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?”

Our electronic device will take the WannaBeMoms into a different world of baby-making. See  http://s755.photobucket.com/user/vaclavkirsner/library/Second%20album/Pregnancy%20and%20birth%20control%20how-to%20by%20bioZhena?sort=2&page=1 = a pictorial “Pregnancy and birth control how-to by bioZhena”.

For a woman in her 30s who’s 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. Should you be new to this, https://biozhena.wordpress.com/about/ is an introduction.

Automatic pregnancy detection is inherent  in the Folliculogenesis In Vivo™ cyclic profile

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”, and you can 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 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 patient, that is, 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.

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

fecundoscitus!!! 🙂

MENOPAUSE, HRT, AND BIOZHENA

December 18, 2007

For these and other terms, see the Alphabet of bioZhena at /2007/11/28/the-alphabet-of-biozhena/

You’ll find much more there under Menopause, HRT, and bioZhena.

Klimt’s Medicine mural

The OvulonaTM is an individual woman’s health monitoring tool, primarily responsive to her steroid hormone profile. As such, it may be expected to become useful for the management of menopause, and specifically for the individualization of HRT (hormone replacement therapy) or for the monitoring of the effects of any alternative approach to menopause management. See also under Hot flushes (or flashes) and under End-organ effect, below.

The concept of individualization of HRT has to do with the adjustment of hormone dosages, so as to minimize the drugs’ harmful side effects. The bioZhena technology is an objective and quantitative monitor of the effects of steroid hormones – whether endogeneous or exogeneous (own-body-generated versus administered). On this basis, it is expected to be a meaningful tool for menopause management, both in the hands of health providers as well as conceivably in the hands of the end-users themselves. Besides causing the Ovulona to become a widely used personal tool for women’s health management in the reproductive years, there is a good chance that the technology will naturally extend its usefulness into the post-reproductive years.

Hormone replacement therapy (HRT):

The use of synthetic hormones, particularly estrogen, to replace the menopausal woman’s diminished naturally self-generated supply of hormones. Prescribed to alleviate menopausal symptoms such as hot flushes, as well as to prevent osteoporosis. Menopause and HRT – initially as “estrogen replacement” or unopposed estrogen – did not come into vogue as a topic of concern for the medical profession until the 1960s, when chemical contraception was introduced.

It is interesting to note that in countries in Asia and South America, where women eat either wild yams or soybeans, which are sources of progesterone, the term “hot flush” does not even exist in their languages. They also rarely suffer from the host of female problems presently plaguing Western women.

It is a fact that an estimated 40 to 50 million American women are now 50, the approximate average age of menopause onset. We believe that the Ovulona will be useful in menopause management in general, and personalization of HRT in particular. The latter has to do with the minimization of side effects of HRT. With respect to that, note that the risk of developing breast cancer, particularly the lobular subtype, is elevated with ‘recent long-term’ use of hormone replacement therapy. This according to a report published in the February 2002 issue of the Journal of the American Medical Association.

For more details, see Another study implicates HRT in breast cancer at http://www.lef.org/whatshot/2002_02.htm (and also http://news.bbc.co.uk/1/hi/health/3018930.stm, or google on HRT report risk of developing breast cancer).

See this April 2007 article at http://www.kaisernetwork.org/daily_reports/rep_index.cfm?DR_ID=44377, which states that as a result of said report, millions of women ceased use of the drugs. Prescriptions for HRT declined by at least 38% in 2003 and by an additional 20% in 2004. Researchers found that in 2003 and 2004, 30,000 fewer women developed breast cancer than would have been predicted by previous trends, and the incidence of breast cancer reached its lowest rate since 1987. Researchers estimate that 16,000 fewer cases of breast cancer are being diagnosed each year because of the decline in HRT use, but experts argue that HRT should not be discontinued or abandoned.

HOT FLUSHES (OR FLASHES):

During the menopausal years, many women experience severe multiple symptoms, to a greater or lesser extent, depending on the individual. In fact, 70% of women experience hot flushes within 3 months of a natural or a surgical menopause. With some, the menopausal impact of estrogen deprivation can go unnoticed. The hot flush – or, medically, the vasomotor flush – is viewed as the hallmark of the female climacteric, experienced to some degree by most menopausal women.

The term is descriptive of a sudden reddening of the skin on the head, neck and chest, which is accompanied by a feeling of intense body heat and often by profuse perspiration. The duration varies from a few seconds (about 30) to several minutes, and rarely an hour or so. The episode ends usually in profuse sweating and a cold sensation. The hot flush frequency may be from rare to recurrent every few minutes, and the flushes are more pronounced at night or during times of stress. The disturbance of sleep results in fatigue, which may in turn lead to irritability, poor concentration, impaired memory, and other deterioration of quality of life. The vasomotor flushes are less frequent and less intense in a cool environment such as in winter months in the northern hemisphere. They can occur in pre-menopause, and are a major feature of post-menopause, lasting in most women for one or two years, but in as many as 25 – 50% of women for longer than 5 years. Unlike other aspects of menopause, hot flushes lessen in frequency and intensity with advancing age.

The physiology of the hot flush is still not well understood, but it apparently originates in the hypothalamus (in the brain) and is brought about by the decline in estrogen at menopause. Vasomotor flushes appear to result from a sudden lowering of the hypothalamic thermoregulatory set point. Activation of cutaneous vasodilation (increased blood flow into skin vasculature) causes an increased peripheral blood flow and thus heat loss, leading to a fall in core temperature. There are hormonal consequences as follows: About 3 to 6 minutes after the flush onset, epinephrine increases in blood (but not norepinephrine), and corticotropin acutely rises 5 minutes after the flush onset, leading to increases in cortisol (15 minutes), androstenedione (15 minutes) and dehydroepiandrosterone, DHEA (20 minutes). While luteinizing hormone (LH) increases and peaks about 12 minutes after the onset, growth hormone also rises, about 30 minutes after the flush. On the other hand, estrogen levels, as well as prolactin, FSH and TSH (follicle-stimulating and thyroid-stimulating hormones) remain stable during hot flushes.

The flush may be preceded by palpitations or headache, and is often accompanied by weakness, faintness, or vertigo. It is understood in gynecology that 10 to 25% of women report hot flushes before menopause, and that women are often treated unnecessarily with estrogen for this relatively common psychosomatic symptom.

In brief, the flush is not a release of accumulated body heat but is a sudden inappropriate excitation of heat release mechanisms. Its relationship to the LH surge and temperature change within the brain is not well understood. It is understood that the flushes are a consequence of the withdrawal of estrogens, rather than of hypoestrogenism (low estrogen levels) per se. The discontinuation of administered estrogens may also precipitate hot flushes, which may also be caused by the infertility drug clomiphene citrate (a nonsteroidal inhibitor of estrogen receptors in the brain).

Obese women tend to be less troubled by hot flushes (because they are less hypoestrogenic).

An estimated 40 to 50 million American women are now 50, the approximate average age of menopause onset, and so it is not surprising that there is much discussion about whether hormone replacement therapy (HRT, see above) causes breast cancer or whether natural hormone creams are effective. The average woman experiencing the onset of menopause can get lost in all the controversies — especially if she is already losing her normal composure because of distressing hot flushes and night sweats.

The bioZhena technology is expected to become a useful tool for the management of menopause, and specifically for the individualization of HRT or for the monitoring of the effects of any approach to menopause management. The concept of individualization of HRT has to do with the adjustment of hormone dosages, so as to minimize the drugs’ harmful side effects.

Alternative approaches include various uses of plant products with natural estrogenic and anti-estrogenic effects that balance and augment the body’s hormone levels. For example, in The Hot Flash Cookbook (Chronicle Books, 1997), author Cathy Luchetti shares her thoroughly researched and tested nutritional solutions for relief of menopausal symptoms. In “No More Hot Flashes!” ( http://216.205.123.2/whatshot/whatshot45.shtml ), Luchetti is quoted saying, “I couldn’t accept the very idea of HRT. I have never believed in pill-popping or other synthetic approaches to health. Yet, I had to do something, because I felt as if my once-dependable body and upbeat attitude were being chiseled away, bit by bit. And being a historian, I kept recalling all the Victorian stories of menopause that ended with the woman becoming ‘unhinged by the change of life.’ I refused to accept that as my fate.”

Luchetti’s words may be considered symptomatic of the attitude of many women today, and bioZhena is in tune with these changing attitudes. Unfortunately for some, though, with addiction and consumerism being what they are, some of our “thoroughly modern Millies” (pun intended) find it almost impossible to recognize that “…to try for hot-flash relief, you should avoid certain foods if you can — especially spicy foods, caffeine, and sweets. Drinking alcohol can also trigger hot flashes”. For those, there exist some over-the-counter herbal supplements “for ridding oneself of hot flashes and other menopausal symptoms”.

As an objective and quantitative monitor of the effects of endogeneous or exogeneous (own-body-generated versus administered) steroid hormones, the bioZhena technology is expected to be a meaningful tool for menopause management, both in the hands of health providers as well as conceivably in the hands of the end-users themselves. This is a logical expectation because some women, especially those still having menstrual cycles, have apparently found that nutritional supplements (such as Dong Quai or Licorice Root) actually aggravated their symptoms. The proponents of these supplements argue that some of the herbs “don’t agree with every woman” and that it is necessary to “give it time and carefully observe its effects in your body.” As in any other situation, a good diagnostic tool is a highly advisable proposition.

End-organ effect:

A concept of biomedicine, which has to do with monitoring of the effects of stimuli, usually chemical stimuli such as drugs, on a biological system, that is either a part of or the complete body of an animal, or a human subject. While the fate of a chemical compound can be monitored by detecting it in body fluids (blood, urine, saliva, etc.), it can also be monitored by measuring the effect on a certain part of the body, called the end organ because the stimulus ends up there. The same applies to stimuli and reactions that the body generates by itself. bioZhena explores electronic monitoring of end-organ effects.

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.

 

BIOZHENA’S MISSION: A HEALTH TOOL FOR EVERY WOMAN

December 10, 2007

Far more than a tool to aid achieving and avoiding pregnancy

In the early years of the project, I published here a modestly formulated version of bioZhena’s vision statement. That was before a female OBGYN physician joined the team and together we broadened the vision and mission.

With the “Ambassador for the Vagina” it became plausible to fully explore the broad applicability of the technology, and to plan pregnancy monitoring and the transformation of the daily-inserted Ovulona into the semi-permanently worn telemetric cervical ring version that Kim the OBGYN named the Halo™.

Friendly Technology - with cervical ring & Ovulograph

For healthcare providers the Ovulograph™, and the Halo™ cervical ring for all women

Our vision is to create a product that practically every woman will want to use. The woman of the 21st century is envisaged to become accustomed to using her daily Ovulona and/or Halo self-check about as routinely as she is using her toothbrush.

It is pertinent to note that a May 2017 Human Factors in Computing Systems study found that the smartphone apps that track menstrual cycles “often disappoint users with a lack of accuracy… and an emphasis on pink and flowery form over function and customization”. Significantly, too, “teenage girls were relying on smartphone apps as their primary form of birth control”. Such evidence indicates that the market is primed for the bioZhena technology breakthrough.

The Ovulona™/Halo™ will be useful to the point of becoming an essential tool of women’s health management, both at home and, when appropriate, via the Ovulograph™, for the provider in the doctor’s office – and for the payer, too. Accordingly, the Ovulona will be supremely user-friendly and affordable for everyone.

The Elevator: Swiss VC/PE deal-maker offers bioZhena to their investors

December 7, 2007

The Elevator, “The Magazine for a Wealth of Opportunity”, December 2007

 

This post is about the integral and unavoidable aspect of project development – seeking development capital. The title could conceivably read “From Switzerland With Love”, if a play on words were intended. Such as the name of The Elevator magazine is a reference to the phrase “elevator pitch”, a standard concept in the venture capital/private equity arena (meaning a very brief introductory pitch of the investment proposition; The Elevator articles are naturally somewhat more extensive than that).

The editor of The Elevator reviewed and published bioZhena after we responded to their invitation, “Seeking Deals to Fund”, http://www.linkedin.com/pub/0/456/786 .

The Elevator (“The Magazine for a Wealth of Opportunity”) is an impressively produced electronic magazine, attached. On page 3, the editor writes: “…since our first issue in March 2006 we have reviewed over 300 projects and retained 60 of them as features. More than 10,000 individuals have seen The €levator ; we’ve had a great diversity of projects, much interest and several deals closed over the past 12 months. … I invite all our readers to become active members of our investor’s forum …“.

On page 35 appears the following claim: OUR TEAM OF EXPERTS PROVIDES ACCESS TO THE BEST SOLUTIONS IN PRIVATE EQUITY, ASSET MANAGEMENT AND VIP ADVISORY.

Here are the headlines from the magazine’s title page, featuring a partial list of contents, and bioZhena is one of these featured listings:

  • How to open your own fund. An introduction by the experts of JP Fund Services
  • bioZhena. The turnkey technology for birth control
  • VentureLab. The professional matching platform
  • The Village Barbados. Prime Luxury Retreat seeking USD 31 million

The interesting thing about this presentation of bioZhena, by the Geneva-area international business VC/PE deal-maker, is their risk scale. We see a scale with 6 colors, from green and light green, through yellow, then light pink and dark pink, and finally the highest risk level is red.

The editor indicates the risk level of the bioZhena proposition as between light green and yellow (or level 4 on a scale of 1 to 11). This is the same as that of the real estate deal “The Village Barbados”, and it is better than the level 5 [yellow] risk level of the VentureLab deal, and it compares favorably with the various other listings in this December issue of the Elevator. Only the Yacht Club Mediterranean and the Castellan, New York real estate deals are assessed with lower risk levels, 2 and 1 respectively.

It is also interesting that bioZhena’s risk level is assessed the same as that of DealFlow, Toronto – “a television series that captures the drama and sport of global business as seen through the eayes of dealmakers”. DealFlow “is currently seeking US$620,000 in a US$875,000 Private Placement Offering of Convertible Preferred shares at US$20.00 per share”.

bioZhena’s investment opportunity is described as follows:

Investment Volume: Up to $ 15 Million (current Offering for $3M plus 1-year $3M Warrant)

Est. Return on Investment: 100%+

Est. Duration: Approx. 3 Years

Minimum Investment: $250,000 or a portion thereof at Company’s discretion

Regarding fetal sex preselection

December 2, 2007

Ovulona(TM) and bioZhena Corporation logo

A new friend, interested in the bioZhena technology and venture proposition, has written to me:

“One question that I’ve gotten is around the accuracy of sex selection. I know this is (or can be) a controversial subject. My wife and I (parents of 3 boys) tried using one of the methods in a book to have a girl on our second try. It didn’t work, obviously, and our son decided to come on his own. Could you please tell me more about that part of the test. I understand it in theory but probably it will need to go into clinicals to validate the claim – right?”

I responded fairly promptly, but without details such as the references and especially some graphics, and without expressing serious doubt about my friend’s book and the advice they had drawn from it. This was my response:

Of course, sex preselection is a controversial subject. Most important, though, is that you understand that this is not our initial product offering; it is merely a well justified expectation (speculation), which requires a study and investment, just like the early cervical cancer diagnosis as well as the birth control uses of the Ovulona technology.

What we have for immediate market introduction is the Ovulona as a tool for aiding conception, as previously passed by the FDA, and that did not include any fetal sexing claims.

[NFP = Natural Family Planning; FAM = Fertility Awareness Method]

We will introduce SFP, Scientific Family Planning. SFA, Scientific Fertility Awareness. All four ™-designated.

For your immediate understanding of this particular fetal sexing implications of the bioZhena technology, you presumably are aware of slide 4. Now I summarize for you where this comes from. Namely, I paraphrase from a detailed white paper, which is available for study upon request, if interested:

…a 1992 publication by John T. France et al., reporting data from 55 pregnancies (and births). The study was based on data whereby only one coitus per fertile period occurred, and three different markers were used to estimate the time of ovulation.

The stringency of the study design by France et al. went so far as to exclude 29% of pregnancies from the birth sex ratio evaluation in terms of timing of conception with respect to ovulation, because of more than one act of intercourse during the fertile period. Significantly, the birth sex ratio was 0.50 for this excluded group but far from 0.50 for the good study population.

The results of the France et al. study were as follows: Of the 34 male infants born, 65% were conceived 2 to 5 days before ovulation, and 71% of the born girls were conceived from intercourse timed between 1 day before to 1 day after the estimated time of ovulation. However, there was a great uncertainty about the actual ovulation day because in only 9% of the cases did the three ovulation markers agree with each other. In 68% of the cycles, agreement was within +/-1 day. The peak cervical mucus marker was one while the other two markers were the onset of the LH surge, and the basal body temperature rise.

Hoping that this mildly specialist language is not just mumbo jumbo to you, the key to this is your understanding that until the emergence of our device there has not been a definitive tool for this; that is, not only predicting but also detecting ovulation – and everything else follows from this simple fact.

The France et al. study was the best, better than some others, but even France et al. did not do everything right. For example, John France was not able to share those 9% of cases where the three methods, which they wisely used (to make up for the absence of a definitive tool), coincided in terms of the day of ovulation. Those 9% could have given us a better, almost definitive baseline. (5 definitive cases, if coincidence of three unreliable methods amounts to definitiveness. 5 = 9% of 55.)

K., this slip into details has been due to your scientific education and the personal level of your prior involvement with the subject, which presumably makes for an appreciation not necessarily to be found elsewhere, in other people.

Having quoted the question and answer verbatim, my next post will attempt to improve the answer (the answer to what may well be a burning question in numerous minds) with the illustrations and explanations. That is: Fetal sex preselection – illustrated . Check it out!

THE ALPHABET OF BIOZHENA WITH CLICKABLE TABLE OF CONTENTS

The Alphabet of bioZhena

A glossary of biomedical terms for bioZhena Corporation

Ovulona and logo

The glossary-and-primer of bioZhena is attached; click on one of the links above.

The glossary is just that! For more details with illustrations and more substantial treatment of certain topics, please go to the the blog, starting perhaps with the Table of Contents . Or try one of the two About pages – one about the blogger and the issues covered here , and the other About bioZhena – tech pitch . See if both these pages include the link to a quick pictorial summary of the bioZhena project, called Tweetroducing bioZhena in 8 slides !

In THE ALPHABET we expand on – and explain the meaning of – the one brief sentence: We have invented the new technology of ovulography™, fundamental to women’s health and lifestyle.

Ovulography is bioZhena’s proprietary technology for monitoring folliculogenesis in vivo. To tell the woman user, which are the three days when she can become pregnant (and the rest of the month when she cannot). And there is more, much more, which is what THE ALPHABET OF BIOZHENA is about. As is the whole of bioZhena’s Weblog .

This glossary/primer of bioZhena Corporation is no Alphabet of Ben Sira — an anonymous work, which has been dated anywhere from the seventh to the eleventh century, and which tells the story of the conception, birth, and early education of the prophet Ben Sira.

There were twenty-two stories (mimicking the twenty-two letters of the Hebrew alphabet) to answer the questions posed by the Babylonian king Nebuchadnezzar. Apart from being notable for the story of Lilith, the primordial first wife of Adam, what makes this ancient text particularly unique and fascinating is its irreverent tone …And, we get to learn of the angels who are in charge of medicine: Snvi, Snsvi, and Smnglof!
