A 2017 update.

Transforming Female Reproductive Health Management prt scr

Explore the few slides including the links in some of them:


bioZhena’s technology platform is bound to revolutionize women’s healthcare with diagnostic tools for women and their doctors & payers.

Empower women with clear menstrual cycle data vs. drugging healthy women & the iatrogenic consequences. That is the first (reproductive management) front, opened along with providing a superior (meaning: definitive) tool with which to tackle the ever-growing difficulty of getting pregnant when planned.

Also unprecedented and important for public health is our way of monitoring cervical health at home. This will work in the background of the primary process, not bothering the user unless a tissue aberration is detected consistently several months in a row. This way of screening, and its affordability, should significantly improve on the Pap smear screening test.

But perhaps – especially if you are a male reader – you may feel that a daily (or almost daily) insertion for the quick self-check is too much to expect of a woman keen on knowing her daily fertility status plus the additional benefits of the routine?

Then our next generation telemetric cervical ring iteration of the same smart sensor is the answer for you. She and her doctor will have a choice.

Friendly Technology - with cervical ring & Ovulograph


My gynecology colleague would argue that the other major healthcare front is even more important, namely our way of providing to the women’s healthcare professionals access to the menstrual cycle vital sign longitudinal records, which she likened to the cardiologists’ ECG recordings but with the important advantage of being affordably and routinely generated by patients at home.

This other major front is providing to the healthcare system the means of obtaining a handle on the management of gynecologic and obstetric medical issues that require better diagnostic evidence for more effective and preventative therapies. In short, we are answering the call and challenge to “Improve the methods and criteria to assess ovulatory dysfunction” (per R.S. Legro MD, 2013).

Current modalities to diagnose preterm labor cannot detect the early biochemical changes of the cervix which result in dilation that leads to preterm births. Once the advanced signs of preterm labor are found, remedies to stop it are often futile and always costly for the healthcare system ($26B annually in USA alone), and frequently have adverse long-term consequences for the prematurely-born child and the family.

The bioZhena technology will alert the women-users and their healthcare providers on a timely basis to the onset of pregnancy-related conditions such as normal and preterm labor. And the detection of pregnancy, whether intended or unintended, is automatic with the primary routine use of the home-use smart sensor.


And here is now the financial pro forma aspect of bioZhena’s breakthrough non-interventional approach to women’s healthcare.

10-year projections:

Minimum Viable Product Scenario (MVS) and Full Value Scenario (FVS)

FVS compared with MVS


bioZhena’s pitch on EquityNet:

Women’s personal sex management for the Information Age.

Generating diagnostic vital-sign profiles for doctors and payers. This first app of proprietary cervical sensor has FDA clearance.

Income from it will support further breakthrough applications.

The gist of the bioZhena women’s healthcare breakthrough is this:

We monitor the brain – sex organs feedback loop.

Nobody else does.


See the illustration below. Grasp the significance: The market offers you anything other than what’s needed, which is the monitoring of the feedback brain – ovary interactions.

“To mitigate the startup investment risk, the first app is an already FDA-cleared electronic fertility monitor for women at home…

Our electronic technology platform is bound to revolutionize women’s healthcare with diagnostic tools for women and their doctors & payers.

… will provide for non-interventional reproductive management, aiding conception and natural birth control without hormones, and automatically detecting pregnancy – planned or accidental. …

We will offer early detection of cervical cancer and other STDs as a built-in screen performed innocuously in the privacy of one’s home – automatically in the background of the primary monitoring…

Ovulona™ tracks the female reproductive cycle via the end-organ effect of the brain-ovary feedback loop on the uterine cervix. Numerous benefits ensue…”

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).

Image file URL:

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…”

Much in women’s health revolves around folliculogenesis – from teen age to peri-menopause

November 30, 2011

In this article I sketch for you the usefulness of the Ovulona™ Smart Sensor™ throughout a woman’s life, with particular attention paid to the extremes of the reproductive lifespan.

We outline the significance of the cervical tissue biosensor for a woman’s health management from adolescence (the teen years) to peri-menopause. This schematic diagram is a pictorial synopsis of the multi-purpose utility of the Ovulona throughout most of a woman’s lifetime.

Ovulona throughout a woman's life

As you recall from prior posts on this blog, FIV™ stands for FOLLICULOGENESIS IN VIVO™, which translates as the sequence of menstrual cyclic records that will be captured and stored (automatically saved) in the Ovulona during normal use by a woman at home. The data is available for transfer to healthcare providers’ Ovulograph™ for medical uses during the reproductive years.

The reproductive age is officially defined as 14 to 44 but we’d encourage, for health reasons, to chop off a few years at both ends from the actual reproductive (high end) or sex-exploration activities (low end). When folliculogenesis – i.e. menstrual cycling – ceases in menopause, hormone therapy and cervical tissue health screening are the two components of menopause and post-menopause health management, to which the Ovulona is applicable.

In this article, I address very briefly (tweetingly!) the two “boundary conditions” of said reproductive years.

I’ll deal with the young boundary condition, i.e. adolescence or teen age, in the style popular nowadays especially at that stage of life . That is, I let speak a few tweets, mostly from .

When you look at the tweetingly referenced papers (click the short URLs below), you will see how the teen cramp sufferer needs our Ovulona. That’s because she must take the anti-inflammatory medication before the ovulation-linked pain hits, otherwise the med would not work. She – or is it you? – must be able to anticipate ovulation. You need the Ovulona. The timing is crucial, similar to the right timing for conception purposes… (Recommended reading: = in the #NSAIDs tweet below).

If it’s menstrual bleeding (not ovulation) that pains you, the Ovulona will tell you when you expect that – whether it is ovulation + 14 days or, probably more likely at this young age, ovulation + irregular. You’ll then see on the display your recorded min and max, with respective probabilities the more accurate the longer you’ve used the Ovulona. That’s this app’s meaning of Smart Sensor™ for you! (And that is because we don’t track just this or that hormone in your pee! Or your BBT, or your signs…)

As for the STD screening aspect of those young years, indicated in the pictorial synopsis above, I refer you to the recent posts in this blog; and the sex ed use of the Ovulona – or rather its recorded data and their discussions in classes – is self-explanatory.

But then there is the subject of chemical contraception, the Pill. So, here, a couple of tweets from’s-really-not-nice-to-fool-mother-nature–or-with/?utm_source=topsy_module

A teenage girl has a #dilemma With the #Pill she brings on herself a significantly earlier #menopause & likely difficulty to #conceive when desired

#Menstrual #cramps are bad but don’t allow them – by taking the #Pill – to cause you the much worse #pain of TTC #infertility    [TTC = Trying To Conceive. That’s the phrase and acronym used by people who have difficulty getting pregnant.] Even with just 3-15 months of #contraceptive #pill use you suffer greater loss of S crypt cells than can be replaced. Then hard TTC is likely   [S crypts are part of the microscopic structure of the cervical epithelium, of the tissues.]

Here now are those few tweets referring to dysmenorrhea, the menstrual pain which causes so much suffering and so many lost hours at school and/or at work. In this day and age!

#NSAIDs against #endometriosis pain Since you must take the meds BEFORE expected #cramps you need our Ovulona tool to anticipate ovulation [NSAIDs = Non-Steroidal Anti-Inflammatory Drugs]

I leave you and this “boundary condition for Ovulona’s use” with two Google Insights graphs. Look here how the worldwide interest level in the subject of period cramps has been increasing since 2004.

Period cramps worldwide searches from 2004 by Google Insights

Period cramps worldwide searches from 2004 by Google Insights

Don’t ask me why the recorded public interest is emanating from those particular English-speaking countries and not from numerous others, and look for details at (you can change the selected parameters and observe the effect of the changes).

I merely note the periodicity developing in the data in recent years on top of the clear upward trend, the periodicity indicative of highest interest in summertime (such as in July 2011)…

This is, of course, the same in the next graph, where I added dysmenorrhea (red) for comparison. That’s a difficult word, so it is not as much searched on as the colloquial cramps – except for, if you look closely, in (Southeast)Asia.

I’ll now use one more tweet to segue into the other end of the span of reproductive years.

#estrogen can be a good medication but we need #personalizedmedicine tools We must measure & titrate #hormone uptake

The following illustration shows that we at bioZhena have the technology with which to do that, i.e. a tool with which to adjust treatment to suit a given female patient.

The illustration is a graph of the effects of estrogen and progesterone monitored with our technology in an ovariectomized pig. Ovariectomy is the removal of the ovaries. It is the animal equivalent of surgical hysterectomy, which causes surgical menopause since the reproductive system no longer produces said sex hormones, the sex steroids estrogen and progesterone.

In the illustrated experiment, the steroids were later given to the animal (after recovery from surgery), and the result was that progesterone drove the sensor signal down versus estrogen drove it up (as seen in FIG. 5 below, excerpted from our patent portfolio). This is a useful finding, for example for monitoring the effects of hormone replacement therapy (HRT). 

Graph of estrogen and progestagen effects on porcine cervix

Graph of estrogen and progestagen effects on porcine cervix

We also have the proof of the concept generated by a menopausal woman, using a Premarin treatment in that experiment (Premarin is an estrogen medication used for treating the symptoms of menopause including hot flashes, vaginal dryness, etc.). The data was used in another patent in our portfolio.

Background on menopause, HRT and bioZhena can be found in the early blog post at .

Experts advocate that women in their 30s and 40s should look at menopause now. Health maintenance depends on diagnostic tools. We propose that the preparation for menopause be done – in a simple quick daily routine – by systematically monitoring the Ovulona menstrual cyclic profile, and how it changes over the years. How it responds to pregnancy and birth, to things like diet, exercise, various ills, various medications, stress… in the particular woman user, not some statistical average. For evidence-based personalized health care.

That’s the broader meaning and the purpose of the folliculogenesis cyclic profile generated by the Ovulona. It’s not merely (“merely”!) for helping to get pregnant or for avoiding pregnancy without chemicals, as is illustrated and described in “Pregnancy and birth control how-to by bioZhena” at this Photobucket site. In the third graphic, on this page, see the follicular waves that relate to follicular age, i.e. how fast is menopause approaching, after pregnancies were successfully achieved and then regulated in this Ovulona-guided manner.

This is because the cervix monitors the physiological inputs after conception and after pregnancy just like it does the monitoring before fertilization and before birth. We pick up the diagnostically useful information from this key female organ. We speak of end organ effects.

For a still broader perspective, including symptometric monitoring correlated with folliculogenesis, go to “Far more than a tool for reproductive management”.

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

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 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 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 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 .

Preparing the execution of Jan Hus

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.]

There then appeared a physician’s tweet “in defense of” the HPV vaccines, dismissive of the public concerns:

@bioZhena responded with a request for the source of the info, i.e., for those “several good publications”.

Please cite them disproving deaths, harm. Email: . I look forward to hearing from you. Hard data is indeed necessary.

Did not receive any, unfortunately.

Meanwhile, the government’s Centers for Disease Control and Prevention – in “Reports of Health Concerns Following HPV Vaccination” – 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.
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 [ ]. 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.

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

Here is a citation [from ]:

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 .

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.

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 paper at . 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 (or ). 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 ]:

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 .

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 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 article, which asks, “Will the labor start naturally on time, or will the baby be so late that induction or Caesarean section is necessary?”: . 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 “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 – [].

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

Comment on Female sexual dysfunction treatment options

June 20, 2010

An excellent overview post appeared on the blog, titled Female sexual dysfunction treatment options, written by Jill of All Trades, MD: .

It is worthwhile to capture the introductory paragraphs of Jill’s post here:

Female sexual dysfunction has been reported in up to 40% of women, and described as causing actual distress in approximately 12% of women.

Michelangelo The Last Judgment, 2 cropped

Michelangelo, The Last Judgment, 2 cropped

Therefore, it is an important topic to familiarize with and screen for as a primary care physician, as many patients may not report these symptoms unless they are elicited during the history taking process of the patient encounter. Female sexual dysfunction is often multifactorial and complex; it is affected by such factors as depression and anxiety disorders, life stressors, interpersonal conflict between the couple, medication side effects, age, religious concerns, personal health, privacy issues, personal body image, substance and alcohol abuse, and hormonal influences.

In order to understand the necessary treatment options, it is important to understand the normal female sexual cycle. There are four phases:

1. Libido: the desire for sexual intimacy, through images or thoughts.

2. Arousal: the increase in heart rate, blood pressure, and respiratory rate, along with increased genital blood flow.

3. Orgasm: the peak of sexual pleasure, with rhythmic contractions of the pelvic muscles.

4. Resolution: the return to baseline with pelvic muscle relaxation.

Michelangelo The Last Judgment

Michelangelo The Last Judgment

The author then very nicely and concisely reviews the treatment options.

I posted the following comment, which at this writing was “awaiting moderation”. –

Thank you for an excellent overview.

I envisage that our Ovulona™ personal vaginal monitor (™ ) will do two useful things for peri-menopausal women and their physicians ( ):

#1. Detect effect of any treatment on vaginal tissues and thus allow for personalization of therapy, titration of medications); and

#2. Allow vaginal delivery of therapeutic compounds.

The Ovulona should become a friendly companion tool for all women, to be routinely used from adolescence to peri-menopause (not only for reproductive management, its primary – or certainly initial – purpose).

To this, for the purpose of bioZhena’s Weblog, I would add a reminder about the significance of the problem of (tissue) atrophy, which the reader will find in The Alphabet of bioZhena (under A in the article titled Atrophy) at .

Atrophy means a wasting away, deterioration, or diminution, any weakening or degeneration (especially through lack of use). Read the article, you’ll see about genitourinary atrophy that leads to a variety of symptoms (in both sexes), affecting the quality of life.

And more, including about “estrogen therapy, which is invariably successful in reversing the atrophic problems. Relief from these problems often results in significant improvements in general well-being.”

In my comment above, #1 (detect the effect of treatment on vaginal tissues), the need for personalization of estrogen therapy is reflected, which requires the end-organ effect measuring tool that we provide. See also under E for End-organ effect in the Alphabet of bioZhena at .

About the Added Bonus of Folliculogenesis Monitoring – Automatic Pregnancy Detection

January 10, 2010


It will really be advisable for women to use the Ovulona™ personal fertility monitor as advocated. Whether pregnancy is hoped for or pregnancy-avoidance is the purpose, diligent routine use of the Ovulona will bring benefits.

What benefits? Not only the correct scientific reckoning of the expected period of gestation (usually spoken of as the EDD or EDC) but also the subject of this article: The automatic immediate detection of pregnancy, which is built into the bioZhena process of menstrual cycle (folliculogenesis) monitoring.

See and hear about this in the narrated slide at . Here is an image of the slide:


We expect that the personal cervix monitoring will be continued after conception has been detected – whether planned or unplanned – for the reason of watching out for or guarding against the possibility of early pregnancy loss (EPL).

Immediate detection

The detection of EPL is based on the understanding of the post-ovulation part of the menstrual cyclic profile signature. In the event of an EPL, the menstrual cyclic profile (which cannot physiologically continue after conception and/or implantation occurs) is logically expected to come back, alerting the woman to try getting pregnant again as soon as possible. This urgency is to reduce the probability of recurring spontaneous abortion as documented in medical literature.

As a 2010 study concluded: Women who conceive within six months of an initial miscarriage have the best reproductive outcomes and lowest complication rates in a subsequent pregnancy. You can read a CNN article about the British Medical Journal published study at . We cite the original BMJ publication at the very end of this post.

“Ask Medical Doctor” [ ] is a web site that provides numerous examples where it follows that our Ovulona™ personal fertility device will be just what the customer needs. And her OBGYN, too.

As an example, here is a posted question (courtesy of @pregnancydoc tweet) [ ]:

“I quit the nuva ring at the end of november, and had a short cycle. I was only on it for a month. My husband an I are trying to conceive. Last week I had a blood pregnancy test, which was negative. As well as the week before. Now I’m almost a week late. I’ve also experienced a little bit of breast tenderness, stomach tenderness, and lower back pain. what’s up?”

Answer by Dr.Bhumika Aggarwal on Fri 08, Jan 2010 10:33pm:

“Hi, Yes you could be pregnant. The only way to know the confirmed cause is a clinical examination by an OBG specialist and if required an ultrasound examination. You could take a urine pregnancy test at home – that would only help a week after you have missed your periods. You should get a blood test for beta HCG levels which would confirm or rule out a pregnancy. This is confirmatory for pregnancy in cases where the urine pregnancy test kit is not helpful. It would be best to consult your doctor without any delay. Regards.”

Commenting on the Ovulona advantage

The above case is not unusual, including the fact that, after quitting hormonal contraception, the menstrual cycle(s) will tend to be short, out of whack. More to the point, however, is that, with the routinely used Ovulona, pregnancy will be detected immediately, by the disappearance of the follicular waves normally appearing in the luteal phase of the cycle [the days after ovulation], whether the cycle is short, long or what have you.

Where the physician talks about the urine and blood pregnancy testing is where it gets interesting. When Dr. B. A. writes, “that would only help a week after you have missed your periods”, with the Ovulona the detection will be immediate and, importantly, the Ovulona will make it possible to monitor the progress of the pregnancy. Where the doctor writes, “You should get a blood test”, that will no longer be the only option for the woman in the early days of uncertainty about her pregnancy status, or in the subsequent early stage of pregnancy.

The point is this: The hCG level in the blood shows the presence of the conceptus, and the immediate disappearance of the follicular waves is expected to show the presence of the conceptus before the hCG test can. The reason is that the hCG test requires a certain minimal level of the human Chorionic Gonadotropin (hCG) to be reached, and then the blood concentration peaks on the analytical instrument’s readout that the service lab will use.

This is how the pregnancy shows in the lab test for hCG:

Conceptus signature - small

Conceptus signature – small

Figure from Proc. Natl. Acad. Sci. U.S.A. 96 (6): 2678–81 (March 1999) or

See also, or .

“Once the fertilized egg implants, the developing placenta begins releasing hCG into your blood.” “hCG appears in the blood and urine of pregnant women as early as 10 days after conception” [ ].

“In non-pregnant women, hCG levels are normally undetectable. During early pregnancy, the placenta produces hCG and its level in the blood doubles every two to four days” [ ].

Nothing is perfect, and “hCG kits can detect a wide and varying range of different hCG-related molecules in serum or urine samples” rather than just the one molecule they want to detect [ ].

“The primary role of hCG in the maternal organism is to serve as a signal to the ovary to maintain the corpus luteum, which would regress if it were not rescued by hCG. … It appears that exponentially increasing amounts of hCG are required to prolong the functional lifespan of the corpus luteum, which explains why the corpus luteum survives early pregnancy but regresses during unfertilized menstrual cycles…” [Parry, S, Glob. libr. women’s med., (ISSN: 1756-2228) 2008 ]. Corpus luteum (yellow body) is defined as a yellow, progesterone-secreting, mass of cells that forms from an ovarian follicle after the release of a mature egg (i.e., ovulation), . It is what becomes of the follicle after ovulation.

How it works

Against that background, we bring up the following expected effect of conception on the folliculogenesis profile as it is tracked by the Ovulona and used by the woman at home. The data accumulated in the memory of the device will be available for use by her physician and the healthcare system.

Précis: When conception occurs, the normal folliculogenesis process changes due to the developing pregnancy (i.e., due to the conceptus). Conception can only occur upon ovulation, and when it does then the change happens – immediately. The follicular waves that normally occur after ovulation can no longer appear.

Upon conception, the maternal menstrual cycling is overruled, taken over, by the conceptus and the placenta. Conceptus is defined as the product of conception at any point between fertilization and birth. It includes the embryo or the fetus as well as the extra-embryonic membranes [ , conceptus is from Latin, something conceived; see concept].

The disappearance of the follicular waves will be immediate, and easily detectable. Importantly, as with the monitoring of folliculogenesis for the purpose of either achieving or avoiding pregnancy, it will be presented to the woman at home in plain English as “pregnancy detected” on the display of her Ovulona device.

A very important (and unprecedented) additional advantage of our technique is that any loss of the pregnancy will also be detected in the process of continued routine monitoring during the pregnancy. This is advisable because many conceptions end in natural loss, i.e., the early death of the conceptus. E. g., “absence of TLX antigen recognition due to sharing of maternal-paternal TLX antigen profiles may not allow anti-TA1 activity and may lead to subsequent fetal rejection”, ( ).

Seriousness of the EPL problem

Between one quarter and one third of pregnancies may fail hours or days after implantation [ , citing Prenat. Diagn. 1998;18:1232–40 and J. Endocrinol. 2002; 172: 497-506]. But see also Further References, below, where the incidence is put at 75%+ of all attempts to conceive – the most common complication of human gestation.

In view of the fact that “treatment of women who present with cramping and spotting in the first trimester of pregnancy would be better guided by a sensitive and specific test that would reliably categorize prognoses for pregnancies”, it is worthwhile to speculate as follows. Since “progesterone appeared to be the single most specific biomarker for distinguishing viable from nonviable pregnancies” [Obst. Gynecol. 2000, Vol. 95, Issue 2, pp. 227-231, ], and in view of our sensor’s mode of operation (and the expected response to conception), we might even speculate that differentiating between viable and non-viable pregnancies might be attempted with our technique, too.

As throughout the whole text in this article, speculate is the key word.

Early Pregnancy Loss, Note: Chief Editor is Lee P. Shulman, MD – one of bioZhena Corporation’s Board of Medical Advisors.


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 is10-15%, 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

The gestational age at the time of the SAB can provide clues about the cause. For instance, nearly 70% of SABs in the first 12 weeks are due to chromosomal anomalies. However, losses due to antiphospholipid syndrome (APS) and cervical incompetence tend to occur after the first trimester. END QUOTE.

What Women Know, And What They Want To Know About Their Fertility Status

October 10, 2009

There: What Women Know

There is no device in the marketplace today that would tell you, in plain English, “today is your fertile day 1” – meaning that sex today is likely to lead to pregnancy. And from our clinical trial results you will know that the pregnancy conceived on this first of the fertile days is likely to be a male fetus, a boy.

There is no such device on the market that would subsequently confirm the pregnancy within days – when, after ovulation on fertile day 3, you – or, rather, your Ovulona device for you – will no longer register the usual follicular waves. Your Ovulona device will interpret that as pregnancy detected, because that is how the biology works.

There is no device out there that would identify the only 3 days in each menstrual cycle during which – and only during which – pregnancy can result from insemination, whether natural or artificial. The commercially available fertility monitors cannot detect either delayed ovulation (which happens due to stress) or when ovulation does not occur at all. In fact, they do not detect ovulation, they just guess at it.

Because the currently marketed fertility monitors (ovulation predictors) cannot detect ovulation, they merely assume its occurrence due to the particular hormonal marker-predictor of their choice (usually LH, in some cases estrogen, in one case both). But no single hormone, even if it were detected with the accuracy of laboratory methods, determines the fertile window. It’s much more involved than that.

Here: What Women Want To Know

Only scarcity of funds keeps us from marketing a device doing all those things not available today.

Our personal self-diagnostic device, the Ovulona™, will tell the woman user in plain English (or any other language) whether today is one of the three days when she can become pregnant.

Fertile window

How? We’ll have the woman monitor at home the process that causes menstrual cycles and is fundamental to women’s health. The use of the Ovulona device is very simple, just like a tampon, except that it is inserted for only a few seconds (about 20) to obtain the result, with an instant display of the result.

Primary use is for reproductive management – that is aiding the achievement of pregnancy, and also aiding fertility-awareness based non-invasive birth control. But there is much more, including an automatic screening for cervical cancer, management of PMS/PMDD and management of hormone therapy, to name just a few useful applications that will come with the core technology.

We show the working of the prototyped product using the graphs of the measurement results plotted against the days of the menstrual cycle. The graphs produce cyclic profiles descriptive of the nuances of the monitored menstrual cycles. None of the old techniques can do that.

These cyclic profiles have important characteristics:

1. The cyclic profile has numerous repeatable features.

2. The range of readings is the same in different cycles and, importantly, also in different women.

3. The profile features are interpretable, and are due to the biological process that causes the menstrual phenomena (folliculogenesis).

The significance of these profiles goes beyond reproductive management.

To wit: Ours is a unique and disruptive technology.

Baseline cycles interpreted

Not included in this illustration is the use of the follicular waves for early pregnancy detection (the waves disappear; the right term for this is “instant pregnancy detection”), and monitoring for early pregnancy loss (in that unfortunate eventuality, the waves come back; it is advisable – by certain recent findings – that the couple should not delay trying to conceive again). Refer to the following for more about said recent findings: original medical publication in BMJ; BMJ editorial comment; article “Miscarriage? Try again ASAP, study suggests”; bioZhena’s post “Instant detection of pregnancy and of Early Pregnancy Loss, EPL – the adversary of Trying To Conceive, TTC – especially after age 25”.

Far more than a tool for getting pregnant and for pregnancy avoidance

On symptometric monitoring correlated with folliculogenesis: Why it is essential for effective diagnosis in women’s healthcare

The purpose of this article is to bring to your attention the big picture. That is the fact that the potential impact of the bioZhena technology goes beyond reproductive management. We illustrate how we mean it when we invoke the vision that the Ovulona device will become a friendly routinely-used companion tool with numerous diagnostic ramifications for women everywhere.

The natural interest of the woman-user in being in charge of her reproductive life leads to the possibility of using the information gathered in the process for additional medical purposes, some not so obvious in the context of the menstrual cycle signature. The Ovulona cyclic profile is the signature of the menstrual-cycle vital sign.

You will follow the discussion here better if you peruse the bioZhena weblog article, listed under Pages and titled, What is symptometric? What is the meaning of “symptometric data”? The answer in a nutshell: Symptometry means symptoms quantified and charted.

Now for a possible application. You probably do realize that there are gender differences in how patients respond to therapy, and you do not need reminding that cardiovascular disease is a big problem for women’s health, far from killing mainly male victims.

In this context we hint at an electronic interface that will function to navigate through a menu that provides for a daily registration of quantified symptoms by means of one of the standard medical symptometric inventories such as the Calendar of Premenstrual Experiences (COPE), or the Daily Record of Severity of Problems (DRSP), etc. This will replace the paper forms used today, and the data from any number of months stored in the device will be transferred to the patient’s healthcare provider(s). The longitudinal record of menstrual cyclic signatures provides a new means of patient profiling.

By design, the symptometric data will be correlated with the Ovulona data on folliculogenesis – and will be far better than the old, inefficient and costly, paper-using procedures of yesteryear (those did not employ any folliculogenesis correlation, of course). No need to invoke the evolving societal requirements in general healthcare policy towards cost-effectiveness, etc.

A recent health news headline declares: “More evidence that depression is hard on the heart”, and here is the synopsis: Severe depression may silently break a seemingly healthy woman’s heart. Doctors have long known that depression is common after a heart attack or stroke, and worsens those people’s outcomes. Monday, Columbia University researchers reported new evidence that depression can lead to heart disease in the first place [ 03/10/09 06:29 © Copyright The Associated Press].

The issue is not the reported “big surprise: Sudden cardiac death seemed more closely linked with antidepressant use than with the depression symptoms the women reported. That might simply mean that women who used antidepressants were, appropriately, the most seriously depressed, cautioned lead researcher Dr. William Whang. But he said the finding merited more research” [loc. cit.].

The issue is that not only more research but all routine women’s health practice requires the knowledge of how symptoms relate to (correlate with) the course of the menstrual cycle or, more accurately put, the course of folliculogenesis.

For an illustration, refer to Premenstrual syndrome (PMS) and PMDD

Effective therapy requires this differential diagnosis, and our technology will do three things for public health:

1. Enable routine quantitative recording of symptoms,
2. Correlate symptoms with the underlying folliculogenesis process, and
3. Allow for individualization of therapy (titrate medication doses for individuals).

This is one of the examples of non-reproductive applications of the bioZhena planned products; this is simply a reminder that the core product, the Ovulona™ for reproductive management, is far from the only planned product offering.

The Ovulona™ is the core product with various diagnostic ramifications within the bioZhena Fertility and Health Awareness System™.

The Ovulona is not another ovulation kit, my dear

October 6, 2008

@bioZhena‘s reply to Jennifer K. who wrote: How is this different from the other ovulation kits on the market today? It seems very similar to products I have seen before. QUOTE UNQUOTE

Actually, Jennifer, you are mistaken. There is no such thing available to you in the marketplace today.

Ovulona - single slide 3-day fertile window


None of the ovulation kits – which the Ovulona™ is not – or any other fertility-status monitors on the market today have the required ability to determine fertile day 1, fertile day 2, and fertile day 3 (= ovulation, the last day of the fertile window).

All the existing techniques merely guesstimate the approach of ovulation, and none of them can detect ovulation separately from predicting it. They detect neither the first day nor the last day of your brief fertile window – so, they declare the fertile window to be wider than it actually is.

Let’s try to illustrate this with the following graphical comparison of the Ovulona 3-day fertile window versus the fuzzy and much wider, uncertain window indicated by one of the old techniques. (In this case depicted here it was the so-called Peak mucus method but LH kit and BBT yielded similarly wide and fuzzy fertile periods, that is the days on which intercourse resulted in pregnancy.)

Ovulona 3-day fertile window versus old methods' fuzzy estimation of the fertile period

Ovulona 3-day fertile window versus one of the old methods

Because in the Old Method ovulation was only guessed at, a fuzzy fertile period obtained.

Fuzzy and long. Wrong.

There is no device in the marketplace that would tell you, in plain English (or in Spanish, Chinese or maybe even in Czech!), “today is your fertile day 1” – meaning that sex today is likely to lead to pregnancy. And from our clinical trial results you will know that the pregnancy conceived on this first of the fertile days is likely to be a male fetus, a boy. We base this expectation on the results of other people’s studies, referenced below.

The rationale, briefly, is this: The male sperm live long enough to be available for fertilization when ovulation releases the ovum (egg) from the ovulating ovarian follicle. Whereas the female X-chromosome bearing spermatozoa have a chance to produce a baby girl only if intercourse takes place on the day of ovulation, because of their short lifespan. With the Ovulona, the rationale will have a chance to be tested and/or utilized in real life…

No such powerful tool out there

There is no device that would – subsequent to determining the days of the fertile window – confirm the pregnancy within a day or two. When, after ovulation on fertile day 3 (indicated in the graph here as day 0), your Ovulona would no longer register the usual follicular waves – and the device would interpret that as pregnancy detected, because that is how it works.

In gynecological convention, days of the menstrual cycle are counted from the first day of menstrual bleeding, but the researchers involved in studying the prediction of ovulation use also another counting system. In that counting system, the day of ovulation is day 0 (zero). This is to allow for comparisons of different cycles, because cycle lengths as well as the phases of the menstrual cycle vary from month to month and also, of course, from woman to woman.

Because the sperm can remain viable for several days but the egg can be fertilized only for several hours after ovulation, there are several fertile days before ovulation. Should the egg remain viable for fertilization longer than the believed 12 to 24 hours, there would be also one fertile day after the day of ovulation. Delayed ovulation will have this effect and this is discussed below. Only our menstrual cycle tracking technology can detect delayed ovulation, a very important attribute.

We believe that published evidence from clinical studies of this problem leads to the conclusion that there are only 3 days of high probability of getting pregnant, and that the ovulation day is the last day of this narrow fertile window.

3-day fertile window vs. old method e2

For more on the foundation of this belief (i.e. for the working hypothesis of the 3-day fertile window), see where we show the outcome of the France et al. study of fetal gender pre-selection superimposed on the menstrual cyclic profile generated by our device in a small clinical trial. This indicates how baby gender pre-selection works or rather how it will work when the Ovulona™ is launched in the marketplace.

This is how come that, in the illustrations above including this one, the days of the fertile window are counted back from ovulation, and hence their negative signs in the graph. Day -2 on this time scale is the first day of the fertile window. It is clearly discerned in our menstrual cyclic profile signature, as shown in the first illustration of this post.

How prior art products and methods fail

If you only detect the ovulation day with your LH kit, it is too late for the previous 2 fertile days. Similarly, if you detect an elevated BBT temperature, which rises and remains elevated after ovulation, it is also too late. The timely determination of the pre-ovulation fertile days has always been THE key problem for NFP [Natural Family Planning] and generally for the Fertility Awareness Based Methods of reproductive management.

There is no device out there that would determine the only 3 days in each menstrual cycle during which – and only during which – pregnancy can result from insemination, whether natural or artificial.

The other fertility monitors – including the more recent smart phone apps – cannot detect delayed ovulation (which happens due to stress) despite the LH hormone signaling that ovulation should go ahead. Neither can the various other monitors warn you when ovulation cannot occur because of the failure of dominant follicle maturation in the present menstrual cycle.

There is no other device that would enable you to avoid the expense and hassle of trying to become pregnant with the help of the costly Artificial Reproductive Technologies when your dominant follicle maturation is not happening – which is only detectable with our folliculogenesis-tracking little device for home use.

Your gynecologist, your family doctor – or your psychiatrist if you suffer badly with PMS (diagnosed as PMDD) – does not have the benefit of the folliculogenesis cyclic profiles stored in the Ovulona memory for better diagnosis and better treatment than you can get today. They do not as yet have the benefit of systematic longitudinal recording of your menstrual cycle vital sign signatures, to facilitate better diagnosis of a health problem such as you may have.

There is no other technology that would – automatically and without bothering you at all – keep track of whether your cervical tissues are healthy, and would issue a warning only when detecting tissue aberration several months in a row – to spare you the anxieties and expenses associated with the Pap smear cervical cancer tests’ frequent false positives. Yes, this too is a functionality planned for the Ovulona in the future.

There is no technology as yet available to all women worldwide with these empowering features at a perfectly affordable cost.
