The perils of IVF, of ARTs, of giving birth at old maternal age

April 15, 2012

About epigenetic evidence that should make you think twice+ before you contemplate In Vitro Fertilization and think that having a baby can wait. The bottom line? Be a young mother!

I lighten up this very serious topic by announcing that an unusually early hummingbird scout has arrived here in the Front Range of northern Colorado Rocky Mountains yesterday morning! And the tiny hummie is here today, too! In fact, two of them, the green-back variety!

But on Friday, it was a sad coincidence when, after I “shared” on Facebook the picture of a certain baby in need of a heart transplant, later in the day I happened on a related news. And I tweeted the allowed 140 characters thus: #Infertile #TryingToConceive Warning & clear explanation http://to.ly/cTP3 #IVF protocols seriously flawed – induce epigenetic damage.

In the above-linked summary of a Swiss study about children born by Artificial Reproductive Technology [ART] procedures, “ART children were found to have … a significantly higher risk of cardiovascular disease at a young age.”

Note: “Vascular dysfunction is related to ART per se rather than to parent-related factors. Oxidative stress may represent an underlying mechanism”. Cited from: “Systemic Vascular Dysfunction in Children Conceived by Assisted Reproductive Technologies” http://spo.escardio.org/eslides/view.aspx?eevtid=33&id=976 by Rimoldi SF, Sartori C, demarche SF, Stuber T, Garcin S, Duplain H, Germond M, Scherrer U, Allemann Y.

This problem does not appear to be related to parental factors, but to the ART procedure itself.”

This Circulation 2012 online article also summarizes the background, as follows: “Assisted reproductive technology (ART) involves the manipulation of early embryos at a time when they may be particularly vulnerable to external disturbances. Environmental influences during the embryonic and fetal development influence the individual’s susceptibility to cardiovascular disease raising concerns regarding the potential consequences of ART on the long-term health of the offspring.”

And it is apparently even worse.

According to a position statement by European Society for Human Reproduction and Embryology (ESHRE), http://www.eshre.eu/binarydata.aspx?type=doc&sessionId=2zn3zp4523tjjg45tnjhaev1/Birth_defects_position_papers.pdf QUOTE:

“Children from couples who get pregnant after assisted reproduction techniques (ART), like IVF/ICSI, have a 40-50% increased risk for a birth defect.

A similar increased risk has been reported for subfertile couples who get pregnant spontaneously after a prolonged time period. This increased risk seems thus mainly be due to parental characteristics from the infertility status and not to the treatment given. A recent case-control study from USA has confirmed these findings.” END QUOTE.

Vanya Loroch, PhD is the author of the summary referenced in the tweet above, in the opening sentence about epigenetic damage due to IVF. Readers will benefit from watching his last listed reference, The Ghost in your Genes (at http://www.youtube.com/watch?v=toRIkRa1fYU ).  As Dr. Loroch writes, it is a fascinating BBC show on the topic of human epigenetics. I would say, the movie should be a mandatory infotainment (viewing) material for all teenagers and young adults.

Vanya also provides a micro-primer on epigenetic alterations, which I recommend. It is at the mentioned http://www.loroch.ch/blog/public/danger-ivf-summary-findings (= the above-cited tweet’s short URL: http://to.ly/cTP3 ).

As one of the scientists there contemplates, in the last part of the film, this new epigenetic insight will make you think about being a guardian of your genome – for the sake of the future offspring of your offspring, not just for your own health’s sake. The environmental impact on the health of future generations (yes, in plural) is demonstrated there in a clear way, with very little scientific jargon and much BBC quality.

Incidentally, how the in vitro in IVF causes the epigenetic switch (damage) is shown there, too. Highly recommended. They don’t even mention uniparental disomy (UPD) as I do, below! After you’ve watched the movie, you’ll put it in context, for sure. Especially you, the female “uniparent”!

I’ve written previously about delayed parenting or, rather, mothering: Every year past the optimal fertile age of early twenties is making things harder – on would be Mom, on Baby, on healthcare system, on humankind. Consequences of conception difficulties should not be taken lightly (ref.: https://biozhena.wordpress.com/2010/05/25/difficult-conception-tied-to-pregnancy-complications-addressed/ ). “High-risk pregnancies are more likely in women who have difficulty getting pregnant, with or without help from hi-tech fertility treatments.” That’s citing a specialist medical authority.

In my Facebook Note, titled “Bestia triumphans II and the International Women’s Day. A heresy?”, I put it rather mildly:

Ironically, the consequences of the sexual revolution [i.e., the introduction of the Pill in the 1960s] can only lead to the deterioration of the health of the human lot. The offspring of all those older mothers (and fathers) can hardly be expected to carry an improving human gene pool.

Brief clarifications:

Uniparental disomy (UPD) occurs when a newborn receives two copies of a chromosome, or part of a chromosome, from one parent and no copies from the other parent (http://en.wikipedia.org/wiki/Uniparental_disomy ).

Maternal Age: Women are born with all the eggs they will ever have. Therefore, when a woman is 30 years old, so are her eggs. … Errors can crop up in the eggs’ genetic material as they [the eggs, ova] age over time. Therefore, older women are more at risk of giving birth to babies with chromosome abnormalities than younger women. Since men produce new sperm throughout their life, paternal age does not increase the risk of chromosome abnormalities (http://www.genome.gov/11508982 ).

Heresy or not, I exclaim in the vernacular used during my early adult years in Britain: Damn the bloody Pill!

And, from my even younger years in the “Old Country”, I recall the sadly funny outcry, Lide jsou blbe!, which translates – albeit without rhyming – as: People are imbecile! (daft, idiotic, …). These days, I would not use such language, of course. Not even to those whose job it is to look after healthcare.

The reasons for why I swear at the Pill and other Endocrine Disruptive Chemicals have been discussed previously in this bioZhena’s Weblog. See, for example, Difficult to conceive – Google evidence that pregnancy complications and trying-to-conceive concerns shot up after the Pill launch in 1960s (Regardless of what contraceptive proponents tell you) . You need the gist of the bad Pill effect, here and now? This is the bottom line: “After 3 and up to 15 months of contraceptive pill use, there is a greater loss of the S crypt cells than can be replaced. … S crypts are very sensitive to normal and cyclical stimulation by natural estrogens, and the Pill causes atrophy of these crypts. Fertility is impaired…” and people wait with having kids until it’s too late.

While the Pill- and other drug-making and the various artificial reproductive technologies are a big business (much like war-making), I continue to try and clarify that natural reproductive women’s health management is a must. Gentlemen, we do have the technology for that. Ladies, quite a few of them, already know. Or at least a few of them do – globally.

Smoking affects the menstrual cyclic profile as captured by the Ovulona™, monitoring might help with smoking-cessation

February 21, 2012

80 percent of the 201,773 women who die prematurely from tobacco-related illnesses each year began smoking while they were adolescents. Evidence shows that those young people, who begin to use tobacco, do not understand the nature of the addiction. They believe they will be able to avoid the harmful consequences of tobacco use. They don’t know that “some researchers feel nicotine is as addictive as heroin. In fact, nicotine has actions similar to heroin and cocaine, and the chemical affects the same area of the brain.”

As someone has written, when most girls begin smoking, they are usually caught up in the immediate experience of what appears to be a “cool”, “adult”, or even “glamorous” behavior. They are naive about the powerful addictive nature of nicotine, which, for some adolescents, takes hold after only a few cigarettes.  Among those who had tried to quit smoking, 82 percent were unable to do so.

The tobacco industry spends vast sums of money on persuading people to take up or continue smoking. In its own words, the industry is “a monster which has to be fed”. The industry sees women as a territory to be conquered, and a large portion of the total marketing expenditure is aimed in their direction.

Women appear to be more susceptible to the addictive properties of nicotine and have a slower metabolic clearance of nicotine from their bodies than do men. Women also appear to be more susceptible to the effects of tobacco carcinogens than men, including higher rates of lung cancer.

Girls and women are significantly more likely than boys and men to feel dependent on cigarettes, and more likely to report being unable to cut down on smoking. While various smoking-cessation treatments and strategies appear to work similarly for both sexes, women may face different stressors and barriers to quitting smoking, such as greater likelihood of depression, weight control concerns, and child-care and family issues.

It is estimated that about 30% of deaths from cervical cancer are caused by smoking. Smoking and taking the Pill in combination can increase the risk of heart disease by up to ten times.

Smoking is damaging to women’s reproductive health. It is associated with infertility, complications during pregnancy, and an earlier onset of menopause.

The estimated 20 percent of pregnant women who smoke during their pregnancies subject themselves and their fetuses and newborns to significant health risks, including miscarriage, stillbirth, pre-term delivery, low birth weight infants, and higher rates of infant mortality.

Smoking while pregnant has serious effects on the health of the baby. Untold adverse consequences affect the lives of those children and the people around them. A study from the Centers for Disease Control and Prevention (CDC) reports that smoking during pregnancy also increases the risk by 50 percent of having a child with mental retardation; this increased risk rises up to 85 percent among those who smoke a pack or more of cigarettes each day. The risk for Sudden Infant Death Syndrome (SIDS) increases among infants who are exposed to intra-uterine smoke and to second-hand smoke after pregnancy.

The younger an adolescent is when she begins to smoke, the more severe her nicotine addiction is likely to be. Additional health effects of smoking are: respiratory problems (and decreased physical fitness), dental problems (including periodontal degeneration), coronary artery disease, mental health effects (including nervousness, depression, more high-risk behavior, etc.), health-damaging behaviors, and other negative effects on quality of life (bad breath, wrinkled skin, stained teeth, and other negative effects that influence how she looks and feels).

We have preliminary evidence on how the smoker’s lifestyle affects the FIV™ menstrual cyclic profile captured by the Ovulona™.

Non-baseline profiles flanking baseline subject's AM&PM profile

Baseline cyclic profile of a healthy 30-years old non-smoker woman (who, as a baseline subject, is not taking any medication or contraception) shown here between two cyclic profiles of a smoking mother. The baseline profile was taken twice a day, morning and evening, and the AM and PM records show not only the reproducibility but also how the post-ovulation follicular waves develop between the morning and evening hours. The smoker’s consecutive profiles are similar to the baseline but exhibit significant differences. Cycle 4 record captured a delayed ovulation and short luteal phase. Cycle 5 shows also a short luteal phase, an abnormality (the luteal phase should be about 14 days long, give or take a day or two).

We can imagine that a young woman trying to quit smoking may be helped in her effort by the Ovulona device. The Ovulona could be prospectively proffered for that purpose as a kind of biofeedback tool.

It is envisaged that tobacco interference with the fertility cycle will be recognized and accepted as a powerful motivator in the hard battle with the extremely strong addiction. “Is appearing ‘cool’ worth the resulting difficulty in getting pregnant, having a healthy baby?”

With public health education, the healthcare providers will be able to use the FIV cyclic profiles of the addicted patients to point out the affected features, and to monitor effects of treatment. “We really want to see this part of your cyclic profile to look more like this…”

The fallacy of ovulation calculators, calendars and circulating-hormone detectors

February 13, 2012

Don’t let them lead you by the nose with likely this and probable that! You need to know for sure.

When it comes to the crucial timing of ovulation, it is astonishing to see the fallacies and delusions propagated on the web – and that this includes even certain generally respected mainstream sources. How they declare, for example: If you’re trying to get pregnant, use this tool to find out when you likely ovulate and are most fertile.

Never mind that “most fertile” makes absolutely no sense because there is no such thing as a little fertile, more fertile and most fertile!

Ladies (and teenage young ladies included!), you either are fertile today or you are not: You either can conceive today or not.

It is either or.

You either are fertile today or you are not. It is not a little bit fertile, or more fertile, or most fertile. Like, you cannot be a little bit pregnant… you either are, or you are not.

Besides which, if you want to conceive a pregnancy, you must know with certainty that ovulation happens when you try to conceive – not merely that it is likely to happen. Unless you are reproductively ill or menopausal, it is always likely to happen at some point but the mere likelihood is not very helpful. Conception absolutely requires ovulation so that the released (ovulated) egg has a chance to be fertilized.

You must have a way of detecting ovulation at home and, based on that instrumentally recorded information, we will also help you with the Expected Date of Delivery (EDD), because that is how it works. Not the LMP (Last Menstrual Period) but the date of the conceptive ovulation — that’s the ovulation with which you became pregnant because your ovulated egg became fertilized. The date of ovulation is the date from which the EDD must be computed.

Ovulation caught on camera

Ovulation caught on camera by Dr. Donnez – impressive but not a practical method of detecting ovulation

Fast forward to the principle that’s behind the take-home message of this post and that’s systematically arrived at by the end of this post:

Briefly: Tracking systemic effects (hormones in circulation) is not good enough for fertility status determination, especially if the purpose is pregnancy avoidance.

.

To be blunt about the language of “likely ovulate” and “most fertile”: Such language simply reflects their inability to be definitive about it – and they therefore resort to guesstimating ovulation, calling it a calculation.

Numerous websites proffer their ovulation calculators when you search online for “ovulation”. A free, printable ovulation calendar and ovulation calculator to help you…, ovulation calculator can help you find the best time to conceive (as if there was some worse time when to conceive!), a calculator to generate your ovulation calendar and determine the best time…, our free Ovulation Calendar helps you predict your most fertile time of the month (ovulation) so that you can achieve pregnancy. Etc.

Notably and significantly, they do NOT promote this for natural (behavioral) pregnancy avoidance (birth control) but only as a tool for assisting conception – as if these were not the two sides of the same coin. They do not because they would get into trouble if they did.

A common approach relies on detecting, in a woman’s urine, the luteinizing hormone (LH) that typically surges on the ovulation day. The LH surge (sharp narrow peak in LH concentration) occurs a few hours before ovulation. Because that is really too late for anticipating ovulation, a related but more sophisticated fertility monitor additionally detects also a metabolite of estrogen, i.e., another hormone, which anticipates the LH surge by about a day.

The worst flaw of systemic hormone monitoring

Fundamentally the most serious detriment is the fact that ovulation as such is not detected by said fertility device or any other such available in the marketplace. Ovulation is merely assumed to occur some hours after the LH surge – but the surge of the LH hormone is merely a trigger signal sent by the brain to the ovary. It says, “ovary, let go of the ovum in our dominant follicle”, but it does not say that the ovary in fact did (or does).

This is a fundamental flaw because ovulation is known to fail to occur in approximately 20% of the follicles. Those follicles, triggered by the LH, undergo the cyclic event of follicle rupture but, despite the rupture, the egg does not come out – there is no ovulation.

Human ovulation caught on camera

In 20% of LH-triggered cases, the egg is not released so ovulation, as photographed here by Dr. Donnez, does not occur

Ovulation also fails to occur with another type of follicles, the so-called luteinized unruptured follicles. Yet, the LH surge can be seen in either case, and is therefore a false indicator.

Furthermore, when stress causes a delay of ovulation or absence of ovulation despite the LH surge signal (signal from the brain to the ovary), this cannot be detected and handled by the urinary hormone-based approach. As you can imagine, with our stressful lifestyle and environment, this is a very serious flaw that results in many disappointments. Our technology will make a big difference in managing the situation.

George Condo - Field of Figures

Since, unlike our Ovulona™ Smart Sensor™ technology, their method depends on biochemical reagents and since the supply of the reagents is limited, their product’s user has to estimate on which day of her menstrual cycle she should start using the hormone-monitoring device when peeing into a cup. She does the estimating based on her previous menstrual cycle(s) as though the length and the timing of the present menstrual cycle were the same as in her previous cycle(s). Alas, that’s not so. Because of the variable lengths of successive cycles in most women, this is a weak feature in their design (even though they are getting away with it).

A key practical problem of the referenced 2-hormone device (the Clearblue® Fertility Monitor) is that the monitored urinary concentration of the estrogen metabolite E3G peaks only about 12 to 24 hours prior to the LH surge. This is not early enough to serve as a marker of the beginning of the fertile phase.

Fertile day 1 not identified

Their research or marketing literature may claim that “a sustained rise in E3G can be used to identify the start of the fertile phase”, referring to the slow gradual increase that eventually becomes the peak of E3G concentration. However, the idea to use an ill-defined rise – rather than the peak in the cyclic profile of the estrogen metabolite – is not a viable solution to the fertile window problem.

Even if the ill-defined E3G rise in the urine were correlated with a clearly defined stage of the egg development towards ovulation, a serious problem is that the rate of the E3G rise differs from cycle to cycle, as do the blood concentrations of E3G. The initially slow increase of the E3G concentration in the urine proceeds at different rates in different cycles, not only at different rates in different women. The E3G rise cannot be predictably associated with the beginning of the fertile period, and it cannot serve as a marker.

Hypothalamus-Pituitary-Gonad Feedback Loop

Schematic diagram of interaction between the LH and FSH hormone-generating glands in the brain (hypothalamus and pituitary) and those of the ovary (female gonad) generating estrogen and progesterone

The reasons are as follows:

1. Estrogen is known to have both stimulatory and inhibitory effects on LH secretion and, to be effective as a stimulant, it must rise to its peak levels (> 150 to 200 pg/ml) and must remain elevated for at least 36 hours [J. Hotchkiss and E. Knobil in E.Y. Adashi, J.A. Rock and Z. Rosenwaks, editors: Reproductive Endocrinology, Surgery and Technology, Lippincott-Raven Publishers, 1996].

In fact, the E3G rise indicates something else:

2. The E3G profile does not reflect the local interplay of estrogen with progesterone because it only reflects clearance of one of at least 10 metabolites of estrogen from peripheral blood circulation into the urine, after oxidative conversion in the liver.

Whatever the rate of this clearance process in the given woman in the given menstrual cycle, there are “local mechanisms due to which the quantification of ovarian steroids in peripheral blood or in urine is rendered interesting but of little value in predicting the genital end-organ effect” [C.J. Verco, in A.M. Siegler, editor: The Fallopian Tube. Basic Studies and Clinical Contributions, Futura Publishing Company, 1986].

The decades old problem is fundamental

This makes for the same basic flaw as that suffered by other monitors of peripheral hormones whether the hormone be progesterone (BBT monitoring) or estrogen (conductivity of saliva or of vaginal fluids).

Thus, the 2-hormone approach is in the end as inaccurate as the other LH-detecting techniques (the OPKs, Ovulation Predictor Kits). Therefore, like the other hormone monitoring methods, it cannot be approved and proffered for pregnancy avoidance since the failure rate would be unacceptably high. In fact, a law suit ensued in England, when the original developer company did sell the LH-and-estrogen monitor as a “contraceptive system”, and a number of unintended pregnancies resulted to the users.

The fundamental point is this: The effects of the local and acute regulatory mechanisms (referenced under 2 just above) remain undetected by the old techniques that work with the peripheral biomarker variables.

Ovarian vein-to-artery exchange of steroids, prostaglandins and other bioactive substances is a local transfer mechanism which enables local regulation of ovarian, tubal and uterine functions. The local, as opposed to peripheral, blood concentrations of the steroid hormones are also believed to work with the innervation of the female genital tract (the cervix in particular).

The effects of these local and acute regulatory mechanisms remain undetected by the old so-called prior art techniques that work with peripheral biomarker variables. In contrast, our Ovulona™ detects them – via the cervix, the natural monitor of the female reproductive system.

Gustav Klimt - Medicine mural (complete view)

Gustav Klimt – Medicine mural – Klimt’s primary subject was the female body

The flawed assumption of similar timing of menstrual cyclic events from one cycle to another has been a problem for the BBT and the BBT thermometers. Since the late sixties, the microprocessor technology has been applied by a number of people to the well-tried basal body temperature [BBT] approach to family planning that was originally hoped to work for pregnancy avoidance.

Smart phone apps with the BBT?

The BBT approach is no longer recognized as medically valid even if it may be acceptable to some of the older physicians, and to the younger buyers of an expensive microcomputerized BBT monitor offered from Europe and/or to the users of the more recent smart phone apps based on BBT monitoring.

This is because the so-called basal body temperature is a systemic variable that reflects, among other things, progesterone rise in peripheral blood after ovulation, usually one or two days later.  It is a very indirect and non-specific biomarker. Even though in some women in some cycles a little-understood dip in the temperature graph may apparently be observed one day before the temperature rise, it is clear that the BBT method is of little value due to its lack of predictive capability and due to its fundamental unreliability. The BBT-rise data is known to have a large error bar since the rise can occur from 3 days before to 3 days after ovulation.

For a more detailed critique of the BBT monitoring approach and a rebuttal of a particular European product, peruse Critique of BBT monitoring – DuoFertility rebuttal. Also read a note on 3 things that differentiate our technique from the smartphone apps and particularly the most recent, Natural Cycles .

Briefly: Tracking systemic effects (hormones in circulation) is not good enough for fertility status determination, especially if the purpose is pregnancy avoidance.

.

Purveyors of the old “prior art” technologies get away with it because of the high demand for any help with the serious and growing problem of sub-fertility, more commonly called trying-to-conceive or difficult getting pregnant. When the purveyors publish anecdotal evidence of “efficacy” in the form of thank-you letters from women who did achieve pregnancy, we should keep in mind that the women received help in focusing on trying to hit the fertile period regardless of whether the given technology actually did work or not.

If any of the “prior art” did work reliably, it would be used as a pregnancy-avoidance tool, which is not the case (with the one exception noted above, a reservation included suggesting that only women with self-assessed regular cycles opted to buy the BBT-and-calendar based app with its 11 “unsafe” days offered to the user instead of the true fertile window).

Stress and fertility: How stress affects the inherently narrow fertile window

Stress and fertility

How stress affects the inherently narrow fertile window

To read the whole post, click on either of the antique-book images or on Reblogged from bioZhena’s Weblog:

Before you go there, here is a little update. New research into stress and fertility was published since I wrote the blog post in December 2007, and here is a summary of an article titled “Stress puts double whammy on reproductive system, fertility” (see http://esciencenews.com/articles/2009/06/15/stress.puts.double.whammy.reproductive.system.fertility ).

 

QUOTE: The new research shows that stress also increases brain levels of a reproductive hormone named gonadotropin-inhibitory hormone, or GnIH, discovered nine years ago in birds and known to be present in humans and other mammals. This small protein hormone, a so-called RFamide-related peptide (RFRP), puts the brakes on reproduction by directly inhibiting GnRH.

The common thread appears to be the glucocorticoid stress hormones, which not only suppress GnRH but boost the suppressor GnIH – a double whammy for the reproductive system. END QUOTE

 

Unlike any other fertility monitoring technology, bioZhena’s Ovulona™ is a Smart Sensor™ in vivo monitor of folliculogenesis. Unlike any other fertility monitor, the Ovulona is basically involved with the always-present stress responses – through monitoring certain end-organ effects on folliculogenesis. The other techniques monitor only this or that circulating hormone – not good enough. The end-organ effect(s) is what counts.

How stress affects the inherently narrow fertile window

Stress can do unwanted things to a woman and her menstrual cycle. In a nutshell, stress can make a woman completely infertile in this menstrual cycle (e.g., LPD, see below), or it can change the timing of her fertile window (the time of ovulation included) within the menstrual cycle. Any of this can cause problems and lead to more stress…

The medical term is stress response, and it refers to the overall reaction of the organism to any adverse stimulus, whether it be of physical, mental or emotional kind, internal or external. The purpose is to adapt to challenge, and this goes on all the time. (C’est la vie! Real life is a never-ending series of stress responses.) Should the compensating reaction of the organism be inadequate or inappropriate, a…

Difficult to conceive – Google evidence that pregnancy complications and trying-to-conceive concerns shot up after the Pill launch in 1960s

December 18, 2011

Regardless of what contraceptive proponents tell you

On this day when Vaclav Havel passed away. In this post, I come out explicitly with an argument against the use of contraceptive pills and related agents (all Endocrine-Active Compounds [EACs]), because of the serious consequences of the sex steroid chemicals for women’s health. I start with evidence from Google statistics.

It is possible to examine the English-language literature for the frequency of addressing certain topics over a period of time. I already did this in the recent post “Seven billion people – after half a century with the Pill”.

Let’s look at data from Google Ngram Viewer about the statistics of the occurrence of certain topics (such as difficult birth) in all books published in English. The data is obtained via http://books.google.com/ngrams/info – for anyone to examine.

Briefly, when we enter phrases into the Google Books Ngram Viewer, it displays a graph showing how frequently those phrases occurred in a corpus of books (here English-language books) over the selected years (here 1900 to 2000). The data is normalized by the number of all books published in each year.

Here we have a comparison of statistics of three phrases:

pregnancy complications (blue),

difficult birth (red), and

trying to conceive (green).

Ngram 6: pregnancy complications, difficult birth, trying to conceive

Ngram 6: pregnancy complications, difficult birth, trying to conceive

The topic of difficult birth exhibits an almost linear growth over the century, even though there are discernible steps in the early years such as the step that followed the plateau (flat portion) lasting from about 1915 to just before 1930, when it “shoots up to catch up with” the overall trend. And, overall, the red curve grows steadily from 1900 to 2000.

In contrast, the blue curve of pregnancy complications and the green curve of trying-to-conceive both shoot up only after 1960, the decade of the introduction of the contraceptive pill. The steep rise in pregnancy complications books (blue) starts soon after 1960. The rise in the number of books about trying-to-conceive (green) starts in mid-1970s and is also distinctly faster than the steady growth over the century of books on difficult birth (red), although it is slower than the pregnancy complications that started going up some ten years earlier.

Of course, the green trying-to-conceive curve is not uninteresting in the early decades of the century, either, if only because it appears that the late Victorians had a significant interest in the topic, much higher than in the other two and especially as compared to pregnancy complications (blue). I’ll leave any discussion of the trend there to others, although the downward trend in the first half of the century would seem consistent with the rise of the birth control movement and with the consequences of two World Wars, and the Great Depression in between.

Those two generations had it tough but, on the other hand, their health, the health of humankind, was not yet assaulted by the sex-steroid chemicals that were introduced in the 1960s.

In a previous bioZhena’s Weblog post, you can see evidence that oral contraceptive use directly and negatively impacts the cervical crypts, which brings about the difficulty to conceive. The bottom line is this: “After 3 and up to 15 months of contraceptive pill use, there is a greater loss of the S crypt cells than can be replaced.” The S crypts are needed for conception.

To further cite Professor Erik Odeblad: “Complications arising from the use of the Pill are very frequent. Infertility after its use for 7-15 years is a very serious problem. S crypts are very sensitive to normal and cyclical stimulation by natural estrogens, and the Pill causes atrophy of these crypts. Fertility is impaired since the movement of sperm cells up the canal is reduced. Treatment is difficult.”

This is a serious problem because, according to medical literature, most American women, “approximately 85% of U.S. women will use the OC (oral contraception) for an average of five years.1 However, women’s OC use, similar to other chronic medications, is often inconsistent and transient.2 Reported six-month OC discontinuation rates vary from 18% to 50%.3,4,5 Unintended pregnancy often follows OC discontinuation” END OF QUOTE. (Am J Obstet Gynecol. 2007 April; 196(4): 412.e1–412.e7)

These data can be read and understood as the double-whammy put on or dealt to American reproductive and public health. That is the high prevalence of trying-to-conceive problems (sub-fertility and infertility) and at the same time the very high rate of unintended pregnancies.

While many proponents of chemical contraception minimize or gloss over the side effects of contraceptive chemicals, it is known that “OCPs (oral contraceptive pills) have several known metabolic effects including increased production of clotting factors resulting in increased risk of venous thromboembolism, increased gallstone formation during the first year of use, and increased risk of liver adenomas (Speroff and DeCherney 1993)” – cited from Ther Clin Risk Manag. 2008 October; 4(5): 905–911 (paper from University of Vermont College of Medicine and Reproductive Endocrinology and Infertility, Women’s Health Care Services)

That said, studies mainly focus on side effects such as amenorrhea, the incidence of breakthrough bleeding and spotting, compliance, discontinuation rates or patient satisfaction, headaches, genital irritation, tiredness, bloating, and menstrual pain.

To cite from said medical publication “Evaluation of extended and continuous use oral contraceptives”, Ther Clin Risk Manag. 2008 October; 4(5): 905–911 QUOTE [emphasis mine]:

In a normally menstruating woman who is not taking contraceptive hormones, progesterone is only present in appreciable quantities during the luteal phase of the menstrual cycle [meaning: after ovulation], after the development of the endometrium. When combination OCPs are administered, the effect of the progestational agent takes precedence over the estrogen component in the reproductive tract, and the endometrium demonstrates this progestin effect (Moyer and Felix 1998). The result is a thin, decidualized (transformed) endometrium with atrophied glands that is not receptive to embryo implantation. Progestins also cause thick, impermeable cervical mucus, preventing sperm from reaching the uterine cavity, and also decrease tubal mobility, altering the movement of sperm and oocytes through the fallopian tube (Johnson et al 2007; Rossmanith et al 1997) END OF QUOTE.

This is consistent with the Erik Odeblad findings about the fine structure of the cervical tissues. http://humrep.oxfordjournals.org/cgi/content/full/18/9/1782

Further to the examples of studies about the mainly short-term effects of chemical contraception, here are examples of published findings about the harmful long-term effects of the sex steroid chemicals administered to healthy women. This is not a systematic review, merely a couple of examples.

BONE HEALTH:

The conclusion of “Effects of Depot Medroxyprogesterone Acetate and 20 μg Oral Contraceptives on Bone Mineral Density” [Obstet Gynecol. 2008 October; 112(4): 788–799]is as follows:

QUOTE Use of very low-dose OCP (Oral Contraceptive Pill) may result in a small amount of bone loss. DMPA (depot medroxyprogesterone acetate) use results in greater bone loss, but this is largely reversible at the spine. Use of very low-dose OCPs after DMPA discontinuation may slow bone recovery.

As a result, the Food and Drug Administration issued a warning in 2004 advising women to limit its use to ≤2 years.

Oral contraception (OC) containing only 20 μg ethinyl estradiol (EE) may also adversely affect bone health, especially if used during adolescence. END OF QUOTE [emphasis mine].

HEART HEALTH:

According to J Clin Endocrinol Metab. Author manuscript; available in PMC 2011 November 9 (Published in final edited form as: J Clin Endocrinol Metab. 2007 August; 92(8): 3089–3094), “whether OCP use in healthy young women is associated with increased CV (cardiovascular) risk is controversial. However, a recent meta-analysis of 14 studies showed that current use of low-dose OCPs increased the risk for myocardial infarction by 84% (37). More data are available regarding CV risk associated with estrogen/progestin use in older women… The Heart and Estrogen/Progestin Replacement Study showed an early increase in events and no benefit overall in women with known CV disease, and the Women’s Health Initiative (WHI) trial demonstrated an increase in CV events in healthy women (38, 39).” END QUOTE.

Returning to Odeblad’s results on the consequences of the Pill for the cervix uteri, that is on how contraceptive chemicals make it difficult to conceive later – and reiterating the take-home message put forward previously in “About atrophy, reproductive aging, and how it’s really not nice to fool Mother Nature – or with”:

Natural aging of cervical S crypts (= cervical aging of a woman never pregnant and never on the Pill):

S crypts, which are needed for conception, are down to 20% at 40 years of age, at the natural aging rate -2% per year. Here you have the reason why a too mature age leads to sub-fertility and to infertility. My remark: The optimal age for motherhood has always been and always will be the early twenties of a woman’s life.

Atrophy acceleration effect of 10 years on the Pill:

S crypts are down to mere 10% at 40 years of age. Here is why it’s not nice to fool Mother Nature, why it’s not good to mess with her design. Fertility is drastically reduced. The Pill is an archetypal anthropogenic Endocrine-Active Compound [man-made EAC]. It was brought up previously in this blog how there are very many of these EACs, all insulting the female body and health; some – like chemical contraceptives – by design. Having invoked the design, I am reminded that the original designers of the Pill had no idea about contraception – they were pushing the frontiers of steroid chemistry… (not this particular application of one kind of steroids).

Atrophy slow-down or beneficial effect of pregnancies:

S crypts only down to 40% at 40 years of age. Here you see Mother Nature’s design in action. Pregnancy slows down the inherent rate of natural cervical aging (atrophy, deterioration). The effect of 4 pregnancies was measured in the Odeblad research. This is not to argue for 4 pregnancies per lifetime – it’s merely how the difference between with and without was made more “easily” measurable in the very difficult studies.

And again, the bottom line is this: “After 3 and up to 15 months of contraceptive pill use, there is a greater loss of the S crypt cells than can be replaced. …S crypts are very sensitive to normal and cyclical stimulation by natural estrogens, and the Pill causes atrophy of these crypts. Fertility is impaired since the movement of sperm cells up the canal is reduced.” END QUOTE.

In case you’d like to view the Carlo Adelio Galimberti picture accompanying the concluding words, please re-visit the cited earlier post. The concluding words were and still would be: While the story of Laodamia and Protesilao is touching, I merely want to ask that girls, ladies and their physicians do not moon the messenger.

P. S.

Vaclav Havel would smile at the image of “mooning” Laodamia. I smile at the thought of his riding the children’s scooter (kolobezka) along Saint Peter’s heavenly corridors (looking for Olga? Since Pani Dagmar remained down there?). He reportedly did that scooter-running in the “labyrinthine” corridors of Prague Castle…

And now, go and check out the 2012 post “The fallacy of ovulation calculators, calendars and circulating-hormone detectors” at https://biozhena.wordpress.com/2012/02/13/the-fallacy-of-ovulation-calculators-calendars-and-circulating-hormone-detectors/

Seven billion people – after half a century with the Pill

November 14, 2011

More than a week before the numerologically so exciting (!!) date of November 11 this year of AD 2011, the population of the world officially reached the count of 7 billion – and this should not go unnoticed in a blog that is about women’s health and human reproduction management. Why, by the time the 11-11-11 day came about, more than 2.5 million more babies were born around the world.

Eyeball the “infographic” data below here, accepting that the image contains one of the small European languages. You can handle this because it is a graphic representation of the world and its population. The data is based on a United Nations Report about the State of the World Population. I did not find anything like this infographic when I googled for said UN report, and the bigger languages of Europe were presumably preoccupied by other concerns (like the economy, and the associated politics, stupid…).

So, we refer to this source with all those un-English letters with diacritical marks [RB, Lidové noviny. From: http://www.lidovky.cz/je-nas-7-miliard-lidstvo-v-budoucnu-uzivi-jen-zemedelska-revoluce-phq-/ln_zahranici.asp?c=A111031_085513_firmy-trhy_mev ]. It’s the numbers and symbols that matter, including the relative sizes of the circles. And note also that the blue circles represent the size of the respective continents’ populations in 2010 versus the red projected population sizes in the year 2050.

By 2050, only Europe’s population will have decreased (projected by 19 million), while all the other continents’ populations will have continued to grow. North America’s population, by the way, is projected to grow only due to immigration, otherwise it would be dropping, too. At least the USA’s would.

World population

World population

http://www.lidovky.cz/foto.asp?foto1=MEV3ed992_2poulaceTTTa.png

12 years times 365 days/year = 4,380 days

Population growth = 1,000,000,000 people / 4,380 days =  228,310.5 people born per day  (2,511,415.5 babies in 11 days = 1 billion divided by 4,380 days in 12 years times 11 days)

Check out the arithmetic of the global population growth in recent days, if you like. It is based on the birth rate of 1 billion births per 12 years. That is indicated in the bottom part of the infographic, showing the worldwide number of people in increasing billions against the years at which the given billion count was reached up to now, and is projected to be reached in the future [rok means year and pocet obyvatel means number of people]. It’s noticeable that the UN-projected future growth rate slows down: see how 16, 29, 27 years between additional billion increments are projected for the next 3 one-billion increments.

I won’t go into the (serious) economic and political consequences of these numbers. Rather, I ask you to note that the current birth rate (1 billion per 12 years) has held steady for the last 3 or 4 one-billion increases in world population. Over most of the last half a century, world population grew in steps of one billion per 12 years.

We see that reaching the first billion of humans took more than 18 centuries (including BC). The second billion then took 123 years and the third 33 years, both these surely influenced by the two world wars. After that, the Pill notwithstanding, almost quarter of a million new people have been and are born globally every day (1B / 4,380 days of 12 years = 228,310.5 births per day).

Evidently, the introduction of the oral contraceptive pills and related contraceptives has NOT quite stopped the global population explosion. But then, what about the United Nations-projected drop in the population of Europe (which is a continent where the Pill is surely available)?

Well, I propose to share with you some data from Google Ngram Viewer, about the statistics on the recent historical occurrence of certain topics (such as contraception) in all books published in English, the data obtained via http://books.google.com/ngrams/info .

Briefly, when you enter phrases into the Google Books Ngram Viewer, it displays a graph showing how much those phrases have occurred in a corpus of books (here English-language books) over the selected years (here 1900 to 2008).

And an important point, also cited from there.

Question: Many more books are published in modern years. Doesn’t this skew the results?

Answer: It would if we didn’t normalize by the number of books published in each year.

Here is an example of the occurrence of three phrases (topics) in English-language books over the century from 1900 till 2008, the latest year available. The topics are: pregnancy complications, difficult birth, and birth complications.

Ngram 1: pregnancy complications, difficult birth, birth complications

Ngram 1: pregnancy complications, difficult birth, birth complications

http://books.google.com/ngrams/graph?content=pregnancy+complications%2Cdifficult+birth%2Cbirth+complications&year_start=1900&year_end=2008&corpus=0&smoothing=5

The N numbers (or the number of phrase occurrences relative to all books) for the three topics are on the same scale as indicated on the vertical axis, and the graph shows that the number of books on difficult birth (red curve) rose steadily over the century – but the books on pregnancy complications (blue curve) and birth complications (green curve) shot up after 1960. These N numbers eventually level off and/or begin to decline after the year 2000. (As though everything has been written up, nothing new to publish?)

There were many more books written about birth control over the same period of 108 years. We can detect this in the N count on the vertical axis, which here has only 3 leading zeros as opposed to the 5 leading zeros at the maximum level in the previous graph (a hundred times as many books, even in 2008, after the decline from the mid-1970s). The initial rise from 1910 to 1930 must have been not on chemical contraception but (mostly) on the then happening calendar method of Ogino and Knaus, i.e. the later discarded so-called “Vatican Roulette”. That approach to birth control did not work – it could not work – so Margaret Sanger took it on herself (and on her wealthy-widow friend, Katharine McCormick) to cause the “magic bullet” of a pill to be developed. Some magic!

Ngram 2: birth control

Ngram 2: birth control

http://books.google.com/ngrams/graph?content=birth+control&year_start=1900&year_end=2008&corpus=0&smoothing=3

One more Ngram Viewer graph, since they say that three is a charm! The following graph compares the number of books on infertility (blue) with the number of books on contraception (red), and it is on the same scale as the birth control graph above (with only slightly lower maximum level, 0.00035% here vs. 0.00045% above).

Ngram 3: infertility and contraception

Ngram 3: infertility and contraception

http://books.google.com/ngrams/graph?content=infertility%2Ccontraception&year_start=1900&year_end=2008&corpus=0&smoothing=3

Three may be a charm, but I will show you one more, so that you (or your friendly gynecologist) will not accuse me of trying to show that chemical contraception has caused infertility (the infertility epidemic). I have merely shared Google’s Ngram Viewer statistics on books written on given topics. Discourses written on contraception preceded those on infertility by at least 10 years, and the number of infertility books was still rising when contraceptive books were already declining in numbers in the 1980s.

Here then is one more Ngram comparing N numbers of books on behavior problems (blue), mental problems (red), and books on birthing (green curve).

Ngram 4: behavior problems, mental problems, birthing

Ngram 4: behavior problems, mental problems, birthing

http://books.google.com/ngrams/graph?content=behavior+problems%2Cmental+problems%2C+birthing&year_start=1900&year_end=2008&corpus=0&smoothing=3

You see that there are four leading zeros in the scale on the vertical axis, so the order of magnitude of the graphed N numbers is between the two orders of magnitude discussed above (it’s an order of magnitude below infertility and contraception). All three of the numbers in this Ngram rise around 1970, behavior problems books before, birthing books after.

Why did the numbers of books on birthing rise so sharply some 15 years after 1960? I don’t know that there is such a thing as invalid questions. The curves for mental health and birth are correlated, rising around 1970, too (not shown here).

Chemical contraception has not worked to reverse the global population explosive growth although it appears to have reduced the extent of the explosion.

But at what cost? Do look at the last Ngram, below, which compares the number of books on birth control (blue), sexually transmitted diseases (red), STD (green), VD (yellow), and STDs (dark blue). It is on the same scale as the birth control graph above (the second in the series). The green spike after 1960 is STD in singular, as opposed to sexually transmitted diseases (red) and STDs (dark blue), which you see rising slowly after 1980, paralleled by the higher green curve in those years, which starts going up even earlier.

This can be rationalized by the fact that earlier on there was merely one STD (or two), called VD in Britain and in Europe (yellow curve), where the rise occurred somewhat later than in the U.S., along with the slight delay in the “sexual revolution” and its consequences or rather the concerns about those consequences. The broad green, red and dark blue hills of elevated N readings before year 2000 reflect the multitude of STDs today, which numbers did not exist before the sexual revolution. The singular VD has morphed into the plural STDs and sexually transmitted diseases.

Ngram 5: birth control, sexually transmitted diseases, STD, VD, STDs

Ngram 5: birth control, sexually transmitted diseases, STD, VD, STDs

http://books.google.com/ngrams/graph?content=birth+control%2Csexually+transmitted+diseases%2CSTD%2CVD%2CSTDs&year_start=1900&year_end=2008&corpus=0&smoothing=3

I leave the “now what” maybe for another time, but a follower of this blog will have an idea.

On the issue of cervical cancer, after remembering Jan Hus – and heresy

July 10, 2011

The other day I tweeted: July 6 1415 Jan #Hus was burnt at the stake in Konstanz DE for #heresy against #doctrines of #Catholic #Church http://t.co/lM1SlwF

So what, you think to yourself? Okay, sure, you and many others have other things to be concerned about – and who cares about a 15th century heretic? Well, maybe some of us do, and I might on this occasion talk some heresy myself. How ’bout that?

But first, let’s be clear about what heresy is, and what Jan Hus’ heretic speech was about, very briefly. This, in case you don’t read the Wikipedia article http://t.co/lM1SlwF about the medieval thinker, a Czech priest, philosopher, reformer, master and rector at Charles University in Prague, chaplain to the royal court, confessor to the queen,  a key predecessor to Luther and the Protestant movement of the 16th century. It was only some 150 years later that “in 1567 Pope Pius V canceled all grants of indulgences involving any fees or other financial transactions” [indulgence = remission before God of the temporal punishment due for a sin after its guilt has been forgiven].

Master Jan Hus Preaching At the Bethlehem Chapel by Alphonse Mucha, 1916

Master Jan Hus Preaching At the Bethlehem Chapel by Alphonse Mucha, 1916

The Czech king (“Good King Wenceslas” of the English Christmas carol fame) supported Hus preaching against indulgences and other such corruption of “the substance and spirit of the gospel“, but the church’s hierarchy, having declared war on Naples, needed vast revenues to fund the war effort… When the sales of indulgences continued, riots broke out in Prague. Three pro-Hus students were beheaded, and then buried to public acclaim in the Bethlehem Chapel. The hierarchy countered by excommunicating Hus (for the second time). The archbishop “interdicted” the city; that is, he deprived the people of al the spiritual resources of the church, a terrifying development in the middle ages.

This is citing from http://www.victorshepherd.on.ca/Heritage/Jan Hus.htm ; there too you can get the rest of the story about the General Council in Constance, which city was then in Switzerland, with Hus guaranteed a “safe conduct”.

You could see at http://dictionary.reference.com/browse/heresy that the dictionary defines heresy as (1) an opinion or doctrine at variance with the orthodox or accepted doctrine, especially of a church or religious system, and (2) as the maintaining of such an opinion or doctrine. In our time, reference could also be to other types of system or establishment.

More to the point of the Master Jan Hus anniversary, and for a scholarly treatise on the punishment that the medieval intellectual received from the then establishment, treat yourself to http://en.wikipedia.org/wiki/Death_by_burning .

Preparing the execution of Jan Hus

Preparing_the_execution_of_Jan_Hus --- Müller-Baden, Emanuel (Hrsg.): Bibliothek des allgemeinen und praktischen Wissens, Bd. 2. - Berlin, Leipzig, Wien, Stuttgart: Deutsche Verlaghaus Bong & Co, 1904.

For, now that I gave you a preamble, I’ll go into a bit of potentially or mildly heretical talk myself, in relation to cervical cancer (and other STDs, sexually transmitted diseases). It is not heresy to remind ourselves that the HPV vaccines do not cure cervical cancer nor do they prevent infection by all strains of HPV – but it could be heretical to discuss that there has been a grave concern among the public about adverse effects, injuries and even deaths in some young recipients of the vaccines.

And even more so to point out that behavior control (the personal health practices referred to below) is advisable in view of the fact that the cancer is associated with early start of sexual activity and with promiscuity. “It is well known that more than 90% of cases of anogenital warts are caused by HPV. HPV has been implicated in cancers of the cervix, vulva, vagina, penis, anus, and oropharynx. The virus is a necessary cause of cervical cancer. [Note that] as many as 24 million American adults–that is, 1 in 5–may be infected with HPV.”

Sadly, and dangerously for the health of all of us, the above-cited phrase about “It is well known” is misleading because it pertains only to medical people (not even to all of them) as opposed to the general population. “Knowledge about the relationship of HPV to cervical cancer is low even in the United States and the United Kingdom.” One of the sources, on which this assessment is based, concludes: Cervical cancer risk factor knowledge, especially knowledge about HPV is low, even among women with the history of cervical cancer. Younger and more educated women are more likely to have HPV and cervical cancer knowledge accuracy. The importance of personal health practices and the focus on health education should be equally emphasized to achieve successful cancer prevention through vaccination. [Emphasis mine.]

Meanwhile, the government’s Centers for Disease Control and Prevention – in “Reports of Health Concerns Following HPV Vaccination” http://www.cdc.gov/vaccinesafety/vaccines/hpv/gardasil.html – states, among other things (albeit not “in real journals”):

Blood Clots
There have been some reports of blood clots in females after receiving Gardasil. These clots have occurred in the heart, lungs, and legs. Most of these people had a risk of getting blood clots, such as taking oral contraceptives (the birth control pill), smoking, obesity, and other risk factors.
Deaths
As of February 14, 2011, there have been 51 VAERS reports of death among females who have received Gardasil. Thirty two of these reports have been confirmed and 19 remain unconfirmed due to no identifiable patient information in the report such as a name and contact information to confirm the report. A death report is confirmed (verified) after a medical doctor reviews the report and any associated records. In the 32 reports confirmed, there was no unusual pattern or clustering to the deaths that would suggest that they were caused by the vaccine and some reports indicated a cause of death unrelated to vaccination. END QUOTE.

Whereupon @bioZhena suggests: The anti-Hippocrates harm does not go away, and cervical cancer screening is no less needed post-vaccination than without it. That’s why @bioZhena’s interest in the topic, as we propose to introduce a better screen than the Pap – but this requires some funding. With our screen done automatically by women at home (in the background of the primary use of the Ovulona™ monitor), the concern that the Pap frequency would suffer in the West is or can be answered, and providing the screen to the population in the non-West countries is a big plus.

Saint Nicholas Day, his legend, and our modern day’s prematurity, EDD calculation, gestational age, problem with LMP

December 8, 2010

Could high prevalence of prematurity be a consequence of motherhood not being the top job held by society in high esteem? A modern paradox.

December 5 is the eve of St. Nicholas Day, the patron Saint of many people, cities and countries – including the largest one [ http://en.wikipedia.org/wiki/Saint_Nicholas#Deeds_and_miracles_attributed_to_Saint_Nicholas ]. St. Nicholas is remembered and celebrated in similar ways in some countries, rewarding well-behaved children but not the misbehaving ones… Which is why St. Nicholas, known as Svaty Mikulas, visits the children at home, in certain parts of Central Europe, in the evening along with an Angel and a Devil (Cert). The Saint asks the parents about the kids’ conduct…

Josef Lada_Mikulas, andel a cert

Josef Lada - Mikulas doma

Josef Lada – Mikulas doma

I share with you a depiction of the tradition drawn by Josef Lada in the troubled 1930s, an idyllic tradition of an industrial people, which they keep to this day…

Besides numerous miracles, this most popular of Saints was and is reputed for gift-giving (hence the commercialized Santa Claus transformation morphing St. Nicholas  with a Western or Northern European Father Christmas later on in the month of December).

There are numerous legends about Saint Nicholas’ miracles and his deeds of help. Perhaps the most famous one is about the three daughters of an impoverished man who could not afford a proper dowry for them, dowry being an ancient habit, the original purpose of which “was to provide ‘seed money’ or property for the establishment of a new household” – and we are now talking about the 300s CE [Christian Era].

The saint Bishop of Myrna saved the girls from the fate of slavery and prostitution by secretly dropping “three purses (one for each daughter) filled with gold coins through the window opening into the man’s house”, which gift made the young girls “eligible” again. It is also said that he dropped the gift down the chimney where stockings were hanging “over the embers to dry, and that the bag of gold fell into the stocking”. That’s beside the point because we are not discussing Santa of Christmas, but rather we are remembering St. Nicolas of December 6.

Jan_Steen_Het_Sint_Nicolaasfeest, The Feast of St. Nicholas

Jan_Steen_Het_Sint_Nicolaasfeest,                               The Feast of St. Nicholas

In those times many, many centuries ago, the chief purpose of young women’s life was motherhood, naturally within a marriage, hence the said dowry habit. In our times, many things have changed, including, unfortunately, young women’s attitude towards motherhood. Well, not just young women’s attitude…

Motherhood must be held in high esteem to reverse the trend reflected by an outcry in tweeter-sphere that’s a part of life nowadays: “I never felt marginalized as a woman until I became a mother”. Now this is very sad. Sad for society since the opposite should be the case.

Motherhood is the most important “job” in the world, and this is not some cute old-fashioned thought. Women bear enormous responsibility for the health of the nation, of humankind. Society should pamper them. Meaning: Society should be organized based on the recognition of Mother Nature’s design, which design – with the optimal years for motherhood in the early twenties – does not go away only because nowadays we can do all kinds of things – including octuplet pregnancies at grandmotherly age.

One consequence of the referenced changes is the currently common delays in getting married, and especially delays in bringing children into the world, starting a family. In other words, the unfortunate consequence is motherhood in later years of life than Nature intended. And then there are other consequences. Among them, prematurity.

@DrJenGunter not too long ago tweeted on prematurity, the most common cause of infant morbidity and mortality in the U.S.: “I just wrote a book on prematurity. Personal and professional experience”. See The Preemie Primer: A Complete Guide for Parents of Premature Babies–from Birth through the Toddler Years and Beyond [Paperback], Jennifer Gunter MD (Author) at http://www.amazon.com/Preemie-Primer-Complete-Premature-Babies/dp/0738213934/

Here is a citation [from http://www.preemieprimer.com/ ]:

My son Victor has dystonic cerebral palsy. He weighed 843 g at birth and had a grade 2 IVH. The bleed resolved in the NICU without hydrocephalus.

He is seven years old now. He is very stiff and is so shaky on a bicycle that we have given up trying for now. He couldn’t stand on one foot until he was 5. It took a very long time for him to get the hang of swimming and at the age of seven he is by no means a fish, but I feel if he were to fall in a pool he could keep his head above water. His digestive tract is very affected, but we have figured out ways to minimize these issues. It took countless hours of OT and thousands of hours of him practicing, but his writing is beautiful and God know where he gets his spelling ability from. He hopscotches like a pro. He is reading a grade level ahead. All without a CT scan or an MRI.

Based on his exam and his problem areas I am sure his cerebellum is a mess. In fact, I wonder if I would have pushed him so hard if I had seen a brain scan before we left the NICU?

“What we know about prematurity” is reviewed by the March of Dimes Campaign at http://www.marchofdimes.com/Mission/prematurity_indepth.html .

Today more than 1,400 babies in the United States (1 in 8 [= 12.5%]) will be born prematurely. Many will be too small and too sick to go home. Instead, they face weeks or even months in the newborn intensive care unit (NICU). These babies face an increased risk of serious medical complications and death; however, most, eventually, will go home. … In fact, the rate of premature birth increased by more than 20 percent between 1990 and 2006. … The rate fell to 12.3 percent in 2008 from 12.7 in 2007, a small but statistically significant decrease.

Why women deliver early? In nearly 40 percent of premature births, the cause is unknown. However, researchers have made some progress in learning the causes of prematurity. Studies suggest that there may be four main routes leading to spontaneous premature labor.”

Štyrský, Marriage

Štyrský, Marriage

Do refer to the referenced article for more about the four main causes:

  1. Infections and/or inflammation.
  2. Maternal or fetal stress.
  3. Bleeding.
  4. Stretching.

And then there is this: These four routes are not the only things to consider. Other factors, such as multiple pregnancy, inductions and cesarean sections, can also play a role. (Mostly man-made factors, we note. I say “mostly” because some multiple pregnancies happen also to women who did not get pregnant through the Artificial Reproductive Technologies… )

Prematurity is bad for infant, parents, and public health. We at bioZhena propose to contribute to the reduction of its prevalence, by making the FOLLICULOGENESIS IN VIVO™ [FIV™] technology available for routine use by women and their physicians. As a particular example, in relation to the referenced other factors, we propose to make it possible to compute the Expected Date of Delivery (EDD) based on the expectant mothers’ folliculogenesis data.

The idea is to get away from the gestation calculation popularized about 200 years ago in 1812 by a Dr. Naegele, for whom the 40 weeks or 10 lunar months rule of obstetrics is named. This rule of 280-day gestation assumes that the mother ovulates on day 14 of a 28 day menstrual cycle, which the readers of bioZhena’s Weblog know that it is an unrealistic assumption.

Napoleon & carabiniers_in_front_of_Moscow_1812

Allegedly*, it was Dr. Hermanni Boerhaave, in his time a highly respected academic physician, botanist and chemist, who read in the Bible that pregnancy should last 10 lunar months. He is said to have formulated – in the 1700s – a way of calculating the expected date of delivery (EDD).

Thus, expectant mothers get EDD today based on the myth of the baroque-era Boerhaave … Yet, already Aristotle taught that “the human fetus is expelled … at any period of pregnancy …; moreover, when the birth takes place in the eighth month, it is possible for the infant to live.”

The gist of the bioZhena hypothesis is this: The EDD can be projected quite well from ultrasonic measurements of the unborn baby’s head and body size, but for a more convenient, affordable and consequently more practical solution, we propose to seek a correlation between the Ovulona FIV™ attributes such as cycle length and the EDD/EDC. Importantly, this will be done by using the date of insemination, which will be easily – electronically – recorded by the user of the Ovulona™ as an integral part of the routine.

Trying to be fair or considerate to the women’s healthcare classics, I report an obgyn.net paper at http://www.obgyn.net/fetal-monitoring/fetal-monitoring.asp?page=cotm/9807/cotm_9807 . It is titled “’Back to the Future’ for Hermaani Boerhaave, or, ‘A rational way to generate ultrasound scan charts for estimating the date of delivery’” by Dr David J R Hutchon, Consultant Obstetrician, Memorial Hospital, Darlington, England. This is about the ultrasound approach, and he comments that: QUOTE “the approach mimics, in modern terms, the method originally formulated by Boerhaave. … If Boerhaave had had an ultrasound scanner, his paper might have read something like, ‘It is proved by numerous observations that 99 out of 100 births occur 22 weeks (at 18 weeks gestation) after the biparietal diameter of the fetus is 40mm’ (Fig 1).”

Besides his Figure 1, I also share Mr Hutchon’s (a British medical doctor, when Consultant, becomes Mr again) Fig. 2, “Regression analysis showing line fit plot. The number of days between scan and delivery has been converted to conventional gestation by subtracting from 280. The lower and upper dotted lines represent delivery at 42 and 37 weeks respectively.” QUOTE UNQUOTE.

Gestation age vs. crown rump length by DJR Hutchon

Gestation age vs. crown rump length by DJR Hutchon

Gestation vs. biparietal diameter by Hutchon

Gestation vs. biparietal diameter by Hutchon

Biparietal diameter is the (outer – inner) measurement of the fetal skull echo. Crown-rump length (CRL) is the measurement of the length of human embryos and fetuses from the top of the head (crown) to the bottom of the buttocks (rump). In humans, the fetal stage of prenatal development starts at the beginning of the 11th week in gestational age, which is the 9th week after fertilization. These are the Wikipedia reported definitions. The two weeks between 9 and 11 assume the “regular” length of the menstrual cycle, which is a theoretical assumption that could very likely be incorrect in practice, in the given woman and in the given last cycle of hers (because regularity is a myth, too). Well, look at the scatter in the data points, it’s telling.

In addition to the convenience, affordability and practicality of the bioZhena approach, do not overlook the feature that the data will be personal to the given woman, and the measurement will not refer to LMP. It will not rely on the woman’s recollection of her last menstrual period (instead, it will refer to the last electronically recorded intercourse); and it will not subject the baby to unnecessary ultrasound radiation.

For more on the topic, try under Gestation in the Alphabet of bioZhena https://biozhena.files.wordpress.com/2007/11/aaee-the-alphabet-of-biozhena.pdf (or https://biozhena.wordpress.com/2007/11/28/the-alphabet-of-biozhena/ ). See also the discussion under Parturition, where we express the expectation that parturition management will be revolutionized by the introduction of the Ovulona into obstetric and gynecological practice.

Summary Definitions [quoted from http://www.righthealth.com/topic/Fetal_Age ]:

Gestation is the period of time between conception and birth, during which the fetus grows and develops inside the mother’s womb.

Gestational age is the time measured from the first day of the woman’s last menstrual cycle [LMP] to the current date. It is measured in weeks. A normal pregnancy can range from 38 to 42 weeks.

Infants born before 37 weeks are considered premature. Infants born after 42 weeks are considered postmature. (Note: 42 x 7 = 294).

Especially with the challenged menstrual cycles that are particularly irregular in length, referencing the LMP in the reckoning can easily introduce a significant error. Perhaps that is why the above summary definition of normalcy is 38 to 42 weeks but prematurity is “before 37 weeks”? (A week here, a week there…) Read also the earlier post https://biozhena.wordpress.com/2008/01/11/about-the-edd-andor-edc-issue-and-a-request-for-input-from-readers/ .

Tomáš Císarovský  - Kukátko

Tomáš Císarovský – Kukátko

280 may have been in the Bible, but it ain’t necessarily right. We’ll see whether 266 is, and whether it is a worldwide constant, which is doubtful. If for no other reason, global constancy is doubtful because it was reported from India that “Mean gestational age at the onset of labour for women native to the area of study was 272 days (standard deviation 9 days). Pregnancies beyond a duration of 280 days showed significantly increased perinatal morbidity.” (Referencing the above righthealth.com definitions, we see 294 – 280 = 14. A week here, a couple of weeks there…)

Well, 272 – 14 = 258. Not 266, and that number is of interest because per Encyclopedia of Childhood and Adolescence, ”a gestation period of thirty-eight weeks (266 days) is calculated for women who are pregnant by a procedure such as in vitro fertilization or artificial insemination that allows them to know their exact date of conception” (article Gestation Period and Gestational Age).

And then you have the oprah.com article, which asks, “Will the labor start naturally on time, or will the baby be so late that induction or Caesarean section is necessary?”: http://www.oprah.com/relationships/Is-Pregnancy-Really-40-Weeks-Long . While debating the validity of the word “necessary” is not the point here, the author there refers to data from studies that concluded greater than 280 days due dates (288 days in one study), of which one study was in Sweden.

A hypothesis can be that hot climates may lead to lower gestation periods than cold climates. This would be a hypothesis based on two data points and a common sense for “the babies taking longer when it’s cold outside”… We’ll want to compare, say, data from Inuits and Lapps on the one hand with data from equatorial Africa and Philippines and/or Indonesia on the other. Logically, we’ll control for factors known or suspected as being involved, such as those four main causes listed above – and age, parity and other factors already explored by people such as Mittendorf in the 1980s.

The idea is that routine use of the Ovulona will provide for an equivalent of the above-referenced 38-week (266 days) calculation, which is available to the women receiving IVF or artificial insemination. The data will be personal and the geography of the birth will be noted (as well as ethnicity), with data sooner or later coming from all corners of the world.

Capturing and working with the fertilization date should, by and of itself, be an improvement over the current way of EDD/EDC assessment. An improvement over the paradox of modern obstetrics and gynecology handling the most important aspect of reproduction by means of some biblical myth, and having become more and more interventionist probably at least in part because of that myth. Reference a recent tweet: Maternity Care In America Rife With Systematic Failures l Being #Pregnant http://su.pr/2j91wY “most people don’t know normal birth”. This refers to the medical staff.

That these thoughts are sensible, and that the chief problem is the LMP, is supported by ultrasound studies such as “Gestational age and induction of labour for prolonged pregnancy” by Jason Gardosi, Tracey Vanner, and Andy Francis (Perinatal Research, Audit and Monitoring, Department of Obstetrics and Gynaecology, Queen’s Medical Centre, Nottingham, UK) in British Journal of Obstetrics and Gynaecology, July 1997, Vol. 104, pp. 792-797 – [http://onlinelibrary.wiley.com/doi/10.1111/j.1471-0528.1997.tb12022.x/pdf].

Citing from this study of more than 24.5 thousand pregnancies: Menstrual dates [LMP data] systematically overestimated gestational age at term when compared with scan dates… suggesting that most pregnancies which are considered ‘prolonged’ according to menstrual dates are in fact mis-dated. The median gestational age for induced labours was 286 days by last menstrual period but only 280 days by scan, and most (71.5%) inductions done post-term (> 294 days) according to menstrual dates were not post-term if scan dates alone are used to calculate the gestational age.“

This study was a retrospective analysis of computer files of 24,675 pregnancies delivered in a teaching hospital between 1988 and 1995.

Here is their graphical summary of distribution of deliveries as a function of gestational ages by ultrasound scan dates.

Deliveries vs. gestational ages by ultrasound scan dates

Deliveries vs. gestational ages by ultrasound scan dates

Their most explicit statement in support of our conviction and plan is this citation: “Even if the date of the last menstrual period is recalled with accuracy, delay in ovulation can result in over-estimation of the true gestational age, which results in an apparent prolongation of pregnancy.” The authors also cite a 1972 paper in American Journal of Obstetric and Gynecology in support of the just cited statement.

The Gardosi et al. paper concluded: Regardless of obstetric and maternal views of the advantages and disadvantages of routine induction policies, our results suggest that most post-date inductions are unwarranted on the basis of gestational age. The incidence of prolonged pregnancies can be considerably reduced by establishing dates by ultrasound alone.

Needless to say, a similar graph for deliveries in India would show the spontaneous labor peak earlier (272 days by one study in tropical Manipal) while a Scandinavian graph would be shifted in the opposite direction; both were referenced above.

I’ll be darned if the introduction of the Ovulona into the gestation arena should not bring some order and peace (as opposed to the mess and anxieties of today). As I wrote in the conclusion of the related January 11, 2008 article: It is perfectly realistic a vision that, in future, an expectant mother’s EDD and/or EDC will be assessed based on her folliculogenesis (FIV™) data.

The EDD/EDC will be computed automatically and provided by her own Ovulona Smart Sensor™. And no Saint Nicholas miraculous assistance will be required by the future users – although we will not write here the same for bioZhena.

* I write “allegedly” because I spent many an hour looking for evidence of truth in this allegation, only to find the Dutch man an impressive medico-scientific mind and an impressive likeable character – but no evidence of the biblical dogma ascribed to him. As I write this note, I am going once more through the tedious but interesting Dr. Boerhaave’s “Academical lectures on the theory of physic” of AD 1744. The man’s fame and authority was such that “a Chinese mandarin, seeking advice, addressed his letter to ‘Boerhaave – Europe’, and it was delivered”. See http://books.google.com/books?id=QTUVAAAAQAAJ&printsec=frontcover&dq=Hermanni+Boerhaave+1744&source=bl&ots=NCeCN4gLdd&sig=SoUA_WS6iSkh2A8WpBX7S4o54Uw&hl=en&ei=ebP-TP2WBIX2tgO12-mvCw&sa=X&oi=book_result&ct=result&resnum=4&ved=0CB8Q6AEwAw#v=onepage&q&f=false

Instant detection of pregnancy and of Early Pregnancy Loss, EPL – the adversary of Trying To Conceive, TTC – especially after age 25

November 11, 2010

Early Pregnancy Loss is also known as #stillbirth or #miscarriage, or Early Embryonic Mortality (EEM), and the Ovulona™ is a tool of evidence-based personalized medicine.

After the optimum fertility age of the early twenties, achieving motherhood gets more difficult. It becomes even more essential than before to know your three fertile days, during which – and only during which – conception can occur.

The simple basic principle is: Fertility status detection must be easy and reliable. PLUS early pregnancy detection is really important, and it should be built-in, an integral part of the conception-aiding tool.

Why? Because:

1) early in pregnancy the conceived baby would be harmed by some of the medications taken by the woman, e.g. by a psychiatric medication with teratogenic effect (harmful to the fetus, causing a congenital disorder);

and 2) because of the annual 600,000 miscarriages – per CDC statistics – out of the 6 million US births, which means that at least some 10% of pregnancies are lost to early pregnancy loss (EPL), miscarriage, stillbirth.

Many EPLs go unnoticed. The EPL is a part of the TTC [Trying To Conceive] or subfertility/infertility problem. Our Ovulona monitor of FOLLICULOGENESIS IN VIVO™ is the prospective solution for managing the problem.

The Ovulona™ detects the 3 fertile days for conception, and it will also automatically detect pregnancy immediately upon conception. Similar to early pregnancy loss — its detection is the inverse of pregnancy detection, which both involve the follicular waves. Like this:

Follicular waves disappear = pregnancy detected

versus

waves reappear in early pregnancy =  early pregnancy loss detected.

Furthermore, the cyclic profile data captured by the Ovulona can be used by your healthcare provider to assess what is going on, and provide more effective help.

DIFFICULT USE OF EXISTING OPKs [Ovulation Prediction Kits] is shown in the following tweet by a @WannaBeMom: “1st month using opk. Do the lines usually start light and then get darker day by day or do they ever go back & forth b4 ovulation?”

Honey is Sweeter than Blood by Salavador Dali, 1941

Honey is Sweeter than Blood by Salavador Dali, 1941

For a woman in her 30s who has had a miscarriage or even two or three, “any delay in attempting conception could further decrease the chances of a healthy baby”, says CNN reporting on a medical study, http://www.cnn.com/2010/HEALTH/08/05/miscarriage.try.again.asap/ .

Study: Women who conceive within six months of miscarriage reduce risk of another.”

November 2016 review and meta-analysis (data on more than a million women): “With an Inter Pregnancy Interval of less than 6 months, the overall risk of further miscarriage and preterm delivery  were significantly reduced.”

These are fundamental principles.

And another principle, not brought up by the CNN or by the study itself, is that a tool for monitoring the early stage of pregnancy for EPL is most desirable. We’d say, mandatory. The Ovulona device monitors (or tracks the process of) folliculogenesis in vivo, which includes the follicular waves that occur after ovulation. The waves disappear upon conception because the reproductive system does not go into another menstrual cycle – it’s pregnant.

In case of EPL, Early Pregnancy Loss (miscarriage), the waves will come back. Early Pregnancy Loss, or Early Embryonic Mortality, is quite a common sad experience of many of us.

The essential point made here is that the woman’s and her physician’s decisions should be guided by the folliculogenesis cyclic profile (and/or its distortion due to distress of any kind). The woman and her doctor should not make decisions or pass recommendations working in the dark, and the data, on which any decision should be based, must be personal to the given patient.

That’s what the Ovulona from bioZhena is for. Personalized medicine. Evidence based medicine.

Automatic pregnancy detection is inherent in the Folliculogenesis In Vivo™ cyclic profile (follicular waves disappear).

This is a screen shot of one of my narrated slides about “what’s going on here” – view (and hear) the slide at https://biozhena.files.wordpress.com/2015/07/single-slide-unprecedented-wealth-of-info-narrated.pps.

Note specifically that: The follicular waves, which occur after ovulation [when the body prepares for the next menstrual cycle], cannot remain in place after fertilization succeeds and conception takes place [because the post-ovulation regime change is even more profound]. That is the principle of instant detection of pregnancy. As opposed to the waiting for the HPT [Home Pregnancy Test] result.

HCG or Human Chorionic Gonadotropin laboratory signature

HCG or Human Chorionic Gonadotropin laboratory signature of the biomarker – detected in a pregnant woman’s urine about 2 weeks into her pregnancy by a HPT home-use urine test – as a color change (into which color the HPT reduces the illustrated complex lab signature)

Should the conceptus [product of conception, early embryo] be lost to EEM, Early Embryonic Mortality (miscarriage), the follicular waves come back to be seen by the Ovulona. That’s the principle of early detection of the miscarriage, and of detecting the return of the non-pregnant condition.

Trying to conceive again should be based on the personal FIV™ [FOLLICULOGENESIS IN VIVO] cyclic profile data generated by the woman trying to have a baby. This is a principle of evidence-based medicine. Personalized medicine.

The Ovulona is intended to help people such as those writing in a forum as follows:

My partner and i started trying for a baby in jan And Concieved in the first month. Unfortunately in march at 8 weeks I had a miscarriage. We have been trying since with no luck. Could something be wrong. Please help this is really getting me down. http://www.netdoctor.co.uk/interactive/discussion/viewtopic.php?t=57881&f=5

We got pregnant the first cycle with both my ds and dd. I am most likely moving to cycle #11 with this baby. We did conceive on the second cycle of trying with baby #3 but we miscarried a week later. Nothing since then. I’m not sure why this time is taking so much longer. http://www.mothering.com/discussions/showthread.php?p=16029816

Can anyone advise? My daughter has been trying to get pregnant for several years. Her husband is fine. My daughter has now been asked to go for a scan which scared the life out of me (you automatically think something is horribly wrong). Can someone tell me what the scan is about – what sort of scan is it? http://www.netdoctor.co.uk/interactive/discussion/viewtopic.php?t=31528&f=5

The information contained in the folliculogenesis cyclic profile, as illustrated in the slide captured above, is meaningful and can help the healthcare provider to answer questions such as these.

In this post we talk again about the feature introduced in an earlier post, https://biozhena.wordpress.com/2010/01/10/about-the-added-bonus-of-folliculogenesis-monitoring-automatic-pregnancy-detection .

This time we focus on the importance of the utilization of the follicular waves not only for practically instant pregnancy detection, but also for a similarly early detection of miscarriage or early pregnancy loss (EPL, also known as spontaneous abortion, SAB). Refer to Early Pregnancy Loss,  http://emedicine.medscape.com/article/260495-overview . Note: Chief Editor is Professor Lee P. Shulman, MD, FACOG – one of bioZhena Corporation’s Board of Medical Advisors.

Excerpted from said Medscape overview: Early pregnancy loss is unfortunately the most common complication of human gestation, occurring in at least 75% of all women trying to conceive. Most of these losses are unrecognized and occur before or with the next expected menses. Of those that are recognized, 15-20% are spontaneous abortions (SABs) or ectopic pregnancies diagnosed after the pregnancy is clinically recognized.

The incidence of spontaneous miscarriage is 10-15%, whereas the rate of recurrent miscarriage is 3-5%. Approximately 5% of couples trying to conceive have 2 consecutive miscarriages, and approximately 1% of couples have 3 or more consecutive losses.

Early pregnancy loss is defined as the termination of pregnancy before 20 weeks’ gestation or with a fetal weight of below 500 g. An article in http://www.cnn.com/2010/HEALTH/08/05/miscarriage.try.again.asap/ summarized the conclusion that “any delay in attempting conception could further decrease the chances of a healthy baby”.

This is a fundamental concept. Further they write, with reference to the original BMJ publication, “Study: Women who conceive within six months of miscarriage reduce risk of another… The women who conceived within six months also had better overall outcomes. They were about 10 percent less likely to have a C-section or a preterm delivery, and about 15 percent less likely to have a baby of low birth weight than the women who waited up to a year.”

This is a highly suggestive conclusion, implying the need to know as soon as possible. The sooner the better for attaining happiness.

Another fundamental principle, not brought up by CNN or by the study itself, is that a tool for automatic monitoring of the early stage of pregnancy to watch out for EEM [Early Embryonic Mortality] is desirable, to put it mildly. Our Ovulona™ device is perfect for that. The Ovulona monitors folliculogenesis in vivo, which includes the follicular waves occurring after ovulation. The waves disappear upon conception (the pregnant system does not go preparing for another menstrual cycle, which the follicular waves signify).

The follicular waves disappear as soon as conception takes place and the woman is in early stages of pregnancy. In case of miscarriage, the waves will come back. The point made here is that the woman’s and her obgyn’s decisions about trying for pregnancy again should be guided by diagnostic data. The data on which any decision should be based must be personal to the given patient – not based on statistical outcomes of studies such as the one referenced above.

That’s what the Ovulona™ from bioZhena is for, the tested and the putative uses of which are discussed throughout the bioZhena’s Weblog.

For a pictorial overview with a written narrative, you can go to http://to.ly/VCF (http://s755.photobucket.com/user/vaclavkirsner/library/Second%20album/Pregnancy%20and%20birth%20control%20how-to%20by%20bioZhena?sort=2&page=1 ) and peruse the 6 pictures with brief written explanations of the basics of FIV™, the ovulographic™ monitoring of folliculogenesis in vivo™.

This one of the 6 illustrations, http://to.ly/1k9L, is about “what’s going on here”.  In other words, what is FOLLICULOGENESIS IN VIVO™, the mechanism of the cyclic profiles, the mechanism of menstrual cycles as detected (and passed on to the Ovulona sensor) by the cervix uteri. Should you want to listen to my spoken narrative, click on the image or on the link below.

The bottom line is this: The multitude of repeatable features of the cyclic pattern makes it possible to determine the boundaries of the fertile window for every individual menstrual cycle.

A key distinction of our technique is that the “dynamic range” of the cyclic profile data (the vertical span) is the same in all cycles and in all women. This – in addition to the repeatable features of the pattern – facilitates electronic interpretation of the data. Only the timing of the various features varies from cycle to cycle, and we work with that.

The cyclic pattern exhibits a number of well-defined peaks and troughs, with the first post-menstruation minimum (or trough, nadir) occurring typically already on cycle day 6, 7 or 8. That’s the selection stage of folliculogenesis (which follows on the stage of recruitment, days 1 – 5). The signal then rises to a maximum (long-term predictive peak, driven by the maturation of the dominant follicle), the highest reading level of the cycle. Over the next several days, the readings fall toward the minimum before the short-term predictive peak. We have found the ovulation-marker minimum after this short-term predictive peak to correlate with urinary LH and FSH peaks (hormones).

Based on data, we interpret the ovulation marker to be an instantly detected effect of the steroid hormone switch that occurs at ovulation (estrogen to progesterone dominance). The follicular waves, which occur after ovulation [when the non-pregnant system prepares for the next menstrual cycle], cannot remain in place after conception takes place [the regime change is even more profound].

That is the principle of instant detection of pregnancy. Should the conceptus be lost to EEM, Early Embryonic Mortality (miscarriage), the follicular waves come back. That’s the principle of early detection of miscarriage also known as spontaneous abortion [SAB], and of detecting and monitoring the return of the non-pregnant condition.

Trying to conceive again should be based on the personal FIV™ [FOLLICULOGENESIS IN VIVO™] data generated by the patient, that is, by the woman trying to conceive. This is a principle of evidence-based medicine. Personalized medicine.
