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.

QUOTE UNQUOTE.

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.

Parturition means birthing (birth) and dystocia a difficult one

January 9, 2008

And what is a parturition alarm?

For these and other entries, see the Alphabet of bioZhena at

https://biozhena.wordpress.com/2007/11/28/the-alphabet-of-biozhena/

Parturition alarm:

This is a concept that has to do with the need to know when labor or delivery is beginning, because the birthing female may be in need of help.

At the time of writing the first Alphabet draft more than five years ago, an Internet search produced only one such technology, a pressure-sensing girth, suitable for the horse breeder only, because it utilizes the fact that the horse mare lies on her side only in the process of parturition. To illustrate, we borrow a nice picture from a more recent publication found in today’s search on parturition alarm, which search still shows a preponderance of equine innovations:

Equine birth alarm

In the originally noted publication, reference was made to some other method that would detect the emergence of the amniotic sac or of the foal from the vulva (vaginal orifice) but that was not a satisfactory solution. In the horse-breeding arena, about 5-6% of births require help. Various approaches to the birth alarm solution have been attempted.

These days, there are quite a few patents etc. found in the parturition alarm search. And even 5 years ago, a patent from New Mexico University should have been found because their intra-vaginal parturition alarm patent (basically for cows) was published in 1987.

In human obstetrics, where most births take place in hospitals, determining the right time of confinement would be very beneficial. bioZhena (and/or its sister company, bioPecus) will investigate our vaginal sensor technology – suitably modified – with a view to developing a parturition alarm applicable to any mammal.

Also relevant in this context is the implication of the Ovulona making available the menstrual cycle (folliculogenesis) data over many months or cycles before conception. This will enable a more accurate anticipation of the EDD, Expected Date of Delivery. You will understand this better below, under Parturition. I highly recommend that you check out Figuring Your Due Date, too – from the Midwife Archives.

Let us put it this way: Since this is the bioZhena blog (and not bioPecus, for veterinary tools), the EDD issue must be addressed first, before any parturition alarm developments. Because we are primarily concerned with the Rerum Naturare Feminina.

And it would still be of great interest to hear from an expert Latinist about the correct way of saying this in plural, the Natural Thing of Women, the Women’s Natural Thing…

This being a reference to /2007/12/16/cervix-uteri-and-seven-or-eight-related-things/ .

Parturition:

The process of giving birth; childbirth. [From Late Latin parturitio, from Latin parturitus, past participle of parturire, to be in labor.]

Parturition is illustrated at http://www.mhhe.com/biosci/esp/2001_saladin/folder_structure/re/m2/s5/ .

The illustration’s legend indicates that physicians usually calculate the gestation period (length of the pregnancy) as 280 days: 40 weeks or 10 lunar months from the last menstrual period (LMP) to the date of confinement, which is the estimated date of delivery of the infant [EDD].

Indubitably, due dates are a little-understood concept:

“Truth is, even if you know the exact date when you ovulated, you still can only estimate the baby’s unique gestational cycle to about plus or minus two weeks” [ http://www.gentlebirth.org/archives/dueDates.html ]. Why should that be? Because of the variability of your menstrual cycle lengths? (They vary even if you do not think so).

Statistically, the gestation time for human babies has a mean of 278 days and a standard deviation of 12 days, an uncomfortably large spread. The old Naegele Rule of a 40-week pregnancy was invented by a Bible-inspired botanist Harmanni Boerhaave in 1744 and later promoted by Franz Naegele in 1812. It is still believed to work fairly well as a rule of thumb for many pregnancies. However, the rule of thumb also suggests: “If your menstrual cycles are about 28 days, quite regular, and this is not your first child, your physician’s dating is probably fine. If your cycles are longer or irregular, or if this is your first child, the due date your physician has given you may be off, setting you up for all kinds of problems” (induction, interventions, C-section among them).

This is where the bioZhena technology can be expected to provide help, making it possible to reckon the EDD with recorded menstrual cycle (folliculogenesis history) data rather than merely with the LMP + 280 days. This, once properly researched, may be expected to have a significant impact on obstetric management. — Any comments?

It is ironic that, in this age of technological medicine, American women worry about their birthing process not being allowed to take its own natural course on account of an ancient method of predicting the EDD.

Ironically, the 40 week dogma – which is the gestational counterpart of the unacceptable calendar method of birth control (the so-called “Vatican roulette”) – does not reconcile the 295+ days of the 10 lunar months; and yet, at the same time, the U.S. has an unusually high perinatal death rate, resulting from high statistics of too early (preterm) labor. Quid agitur? See also under Gestation.

Dystocia or birthing difficulty:

Dystocia is difficult delivery, difficult parturition. From Latin dys-, bad, from Greek dus-, ill, hard + Greek tokos, delivery. Calf losses at birth result in a major reduction in the net calf crop. Data show that 60% of these losses are due to dystocia (defined as delayed and difficult birth) and at least 50% of these calf deaths could be prevented by timely obstetrical assistance. The USDA web site http://larrl.ars.usda.gov/physiology_history.htm is apparently no longer there but when it was it indicated that an electronic calving monitor was being developed to determine maternal and fetal stress during calving. These studies are important since they are leading the way for developing methods to reduce the $800 million calf and cow loss that occurs each year at calving in the USA’s beef herds.

In analogy with the superiority of in vivo monitoring of folliculogenesis versus tracking behavioral estrus (heat), in vivo monitoring of the progress towards parturition must be a priori a more promising approach.

The telemetric version of the BioMeter – the animal version of the Ovulona technology – will hopefully provide a tool for these efforts. Once tested on animals, human use will be a logical extension of the endeavor. (Or endeavour, should it take place in Europe! Smiley…)

Comment about the EDD and/or EDC issue, and request for input:

Again, EDD stands for Estimated Day of Delivery, while EDC stands for Estimated Day of Confinement.

Per Encyclopedia of Childhood and Adolescence, article Gestation Period and Gestational Age [ http://findarticles.com/p/articles/mi_g2602/is_0002/ai_2602000272 ], ” 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.”

The Ovulona device from bioZhena will provide to the woman user a very simple means to record the day of any intercourse. In every cycle, whether pregnancy is planned or not. This must become a part of the routine. The information will be electronically recorded along with the daily or almost-daily measurement data inherent in the use of the Ovulona. With that menstrual cycling history data, this intercourse-timing information will be available for optional use by the woman’s physician(s).

Therefore, the routine use of the Ovulona will provide for an equivalent of the above-referenced 38-week (266 days) calculation available to the women receiving IVF or artificial insemination.

This alone should be an improvement on the current way of EDD/EDC assessment.

In addition, an investigation should be undertaken into the question of whether any inference can be drawn from the woman’s menstrual cycle history prior to the conceptive intercourse. Any comments on this would be welcome, even about anecdotal or subjective or tentative observations that may be available already. However non-scientific, however tentative, however uncertain an individual answer or input from you may be…

E.g., do women with more or less regular cycles tend to exhibit a regular gestation period, and vice versa?

And, certainly, what evidence is available in medical literature (or maybe in unpublished records?) about the outcomes of the IVF and/or artificial insemination pregnancies, i.e., about their documented gestation periods? Does the 38 weeks projection work? Always? If not always, can anything be correlated with any deviation?

Do women with distinctly irregular menstrual cycles tend to have non-regular gestation periods?

The complicating effect of first versus subsequent pregnancy has already been noted, of course…

Conceivably, there is no such preliminary info available, and we shall have to try and gather even these preliminary data in a systematic manner, but – no question asked, nothing learned… Public or private input would be appreciated.

Birthday, and how it relates to the bioZhena enterprise – eukairosic™ diagnostic tools

December 28, 2007

Today is a major anniversary related to the bioZhena enterprise. Namely, a round-number (and not small) birthday of the offspring whose begetting had much, if not everything, to do with the inception of the project.

The biologically educated member of the would-be parental team insisted that medical help would have to be the very last resort, as she did not wish to be poked in and subjected to the various medical procedures available in the country of the proud Albion (that, alas, no longer ruled the waves!), where this awakening was going on. The image of what she resented getting into is telling, and it’s not even the whole story.

Woman in stirups sketch

Awakening on the part of said couple, who till then took steps to minimize or theoretically avoid getting in the family way, owing to circumstances. As in too many instances the world over, the “awakening” was left until somewhat too late. I do not wish to talk about age specifics, but you probably know that particularly female fertility (more accurately put, fecundity or fecundability) decreases starting around or even before the Christ’s age, and so – in retrospect – it was no great surprise to find that achieving pregnancy was not as simple as expected. At the time, actually, this was a great surprise…

At the time, yours truly was not an expert in the field that deals with certain practicalities of the most important aspect of life, by which many of us mean procreation, reproduction, and its management. I am referring to some insight into the practicalities on the female side of things procreative, which insight was not there at the time – but the better half knew the basic fundamental that I now delight in referencing as eukairosic.

In a nutshell, the word refers to the right time, opportune time – exactly what we are about the strategic or “right time; the opportune point of time at which something should be done.” A window of opportunity is kairos time.

For more about this, the Wikipedia article can be recommended, at http://en.wikipedia.org/wiki/Kairos . Let’s cite: Kairos (καιρός) is an ancient Greek word meaning the “right or opportune moment,” or “God’s time” [sic; thus said – but this should say “gods’ time”]. The ancient Greeks had many gods, and two words for time, chronos and kairos. While the former refers to chronological or sequential time, the latter signifies “a time in between”, a moment of undetermined period of time in which “something” special happens. What the special something is depends on who is using the word. END QUOTE.

If you visit that article, you will probably understand why I would like to look at the possibility of adopting as our company logo QUOTE a monochrome fresco by Mantegna at Palazzo Ducale in Mantua (about 1510 C.E.) that shows a female Kairos (most probably Occasio)… UNQUOTE.

You will also appreciate that, since we are not theologians, and because “eu-“ is the Greek prefix meaning well or good or true or easy, my choice of the adjective that we want to trademark as descriptive of bioZhena’s wares is eukairosic™.

And so here, for the sake of accurate definition, is one other item from The Alphabet of bioZhena – /2007/11/28/the-alphabet-of-biozhena/

Fecundability and fecundity:

Fecundability is the probability of achieving pregnancy within one menstrual cycle – about 20% or maybe 25% in normal couples [sic; the probability depends on many factors, including age – vide infra, or see below].

Fecundity is the ability to achieve a live birth.

Fecundability is strongly influenced by the age of the partners, and it is maximal at about age 24. There is a slight decline at ages 24 – 30, and a rapid decline after age 30.

The words are derived from Latin fecundus, fecund, from the root of fetus, via Old French fecond. Fecund means fruitful in children, or prolific.

As for the eukairosic diagnostic tools, their utility goes beyond reproductive management. Due to folliculogenesis (menstrual cycling), even things such as administration of medications or certain diagnostic examinations must be performed at the right time within the menstrual cycle…

Scire quod sciendum

Infertility and A.R.T. or Assisted Reproductive Technologies

December 15, 2007

For these and other entries, see the Alphabet of bioZhena at

/2007/11/28/the-alphabet-of-biozhena/

 

 

Infertility:

Clinical infertility is the inability of a couple to achieve a pregnancy or to carry a pregnancy to term after one year of unprotected intercourse. If the difficulty to conceive lasts less than a year, the condition is referred to as reduced fertility or sub-fertility (see the previous post at /2007/12/14/sub-fertility-or-reduced-fertility/ ). Clinical infertility is classified further into male infertility, female infertility, couple infertility, and unexplained infertility. Studies have shown that in the past 50 years the quality and quantity of sperm has dropped by 42% and 50% respectively. In the past 20 years the decrease in sperm counts has occurred at a rate of 2% annually. For further information refer to Xeno-estrogens (see the Alphabet of bioZhena at /2007/11/28/the-alphabet-of-biozhena/ and the web reference therein).

In the U.S. alone, of the 6.7 million women with fertility problems in 1995, 42% had received some form of infertility services. The most common services were advice and diagnostic tests, medical help to prevent miscarriage, and drugs to induce ovulation [Fam. Plann. Perspect. 2000 May-Jun;32(3):132-7].

 

 

 

A Glossary of Infertility Terms and Acronyms published by the InterNational Council on Infertility Information Dissemination is available at http://www.inciid.org/glossary.html .

 

 

ART or Assisted Reproductive Technologies:

 

Also referred to sometimes colloquially as the “heroic procedures”, they are used to treat infertility patients. ART refers to all techniques involving direct retrieval of oocytes (eggs) from the ovary. They are: artificial insemination (AI), IVF (in vitro fertilization), TET (tubal embryo transfer), ZIFT (zygote intra-fallopian transfer), GIFT (gamete intra-fallopian transfer), ICSI (intra-cytoplasmic sperm injection), blastocyst transfer and other infertility treatments, such as IUI (intra-uterine insemination), assisted hatching (AZH), and immature oocyte maturation (IOM).

Sub-fertility or Reduced Fertility

December 14, 2007

For this and other entries, see the Alphabet of bioZhena at

/2007/11/28/the-alphabet-of-biozhena/

Subfertility (THE INITIAL TARGET OF BIOZHENA):

A state of less than normal fertility but not as bad as clinical infertility. Also called reduced fertility, it refers to the inability to conceive for more than about 4 months but not more than a year (which then becomes classified as clinical infertility, the inability to conceive after a year of unprotected intercourse). It is estimated that as many as one in six couples (17%) have difficulty in conceiving the number of children they want when they want them.

Again: Research suggests that between 14 and 17 percent of couples are affected by subfertility at some time during their reproductive lives. In fact, only eight out of 10 couples trying for a baby do get pregnant within 12 months. For approximately 10 percent of couples, pregnancy will still not have occurred after two years (clinical infertility). Sometimes the label of subfertility is used for couples who have had regular unprotected sexual intercourse for all of two years without conception taking place. This is a reflection of the fact that subfertility is becoming more and more commonplace.

According to one source ( http://www.womens-health.co.uk/ ), even for a healthy fertile couple, the ‘per month’ success rate (conception rate) is only around 15-20%, “so it is not at all uncommon to take some months to conceive”. Overall, around 70% of couples will have conceived by 6 months (a 30% subfertility rate). 85% conceive within 12 months (a 15% subfertility rate, “for the less impatient”). And 95% will be pregnant after 2 years of trying (technically, this is a conservatively estimated infertility rate of 5% – c.f. the 10% referenced above; or, this statistic might be perhaps considered the subfertility rate for the angelically patient). The monthly success rate in this population is 8%, and this statistic drops progressively as time goes on.

As for possible causes of difficulty to conceive, alcohol consumption, even in small amounts, can reduce a woman’s chance of conceiving by more than 50 percent, and smoking “…drastically reduced fertility in our sample”, as wrote a team from the Baltimore-based Health Care Financing Administration, in a report published in “Fertility and Sterility” (1998; 70: 632-637).

In terms of help, many people believe that fertility drugs, even when effective, remove conception from the intimate relationship between the partners, which means that it is to some extent beyond their control. Besides this loss of control, there are drawbacks and disadvantages to all forms of medically assisted conception. Some of them have potentially serious long-term effects. Consequently, many couples prefer to avoid these risks.

Women who describe overcoming infertility with the help of alternative therapists went to them because they had been offered drugs to induce ovulation but were reluctant to take them, when they learned of the possible side effects. Disturbing reports have appeared about the long-term as well as short-term effects of assisted conception. Increased miscarriage levels and premature and multiple births are not only very distressing but have considerable cost implications, both personally and societally (i.e., this is a public health issue). Babies born prematurely, or in multiple births, are at a disadvantage from the start. There are also some reports of increased rates of ovarian cancer in women who have taken fertility drugs, and of cancer in the babies of mothers who have had ovulation induced by drugs.

Subfertile couples are naturally interested in methods and tools that can help them to overcome the difficulty to conceive. The endocrinologist professor Brown may be quoted: “Failing to conceive when wanted is stressful and therefore favours infertility. It should be remembered that, apart from a few conditions such as blocked fallopian tubes, absent sperm and continued anovulation, most couples will conceive eventually without help. However, the modern expectation is one of immediate results, and the main function of assisted reproduction techniques is therefore to shorten the waiting time for conception.” To which we would add that bioZhena aims to offer a more affordable and safer alternative.

With the mentioned statistics of the fertile-age women suffering from the subfertility problem, this is a truly large opportunity in a constantly renewing and growing market. We are talking about 9 or 10 or even 18 million women in the USA alone – or quite possibly many more, taking into account all the impatience and demand for instant gratification in people today; plus about 50% of the 10 million of clinically infertile US couples, that is those who cannot afford the very costly ART treatments. [A.R.T. = Assisted Reproductive Technologies.]

This is the initial, early-stage, mission of bioZhena Corporation: To provide a definitive timing aid to couples experiencing difficulties in conceiving a baby. See also the entry for the Ovulona, where it is explained that, in this situation of reduced fertility, the basic problem is the proper timing of the intercourse.
