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

October 10, 2009

There: What Women Know

Despite the many BBT charting apps and some BBT monitors, and despite the urine analyzing (or the saliva testing) products on the market, here is a fundamental fact:

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 device out there that would detect (not just guess at) ovulation, which will enable you to try to conceive a girl, if that is what you wish for.

There is no such device on the market that would subsequently confirm the pregnancy within a day or two – 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. Because 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.

Ovulona - single slide 3-day fertile window

How? We’ll have the woman monitor at home the process that causes menstrual cycles and is fundamental to women’s health (folliculogenesis). 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.

The Smart Ovulona will display the results electronically interpreted, presented in plain language such as FERTILE DAY 1 while the raw data is stored within the device for optional use by healthcare professionals.

Primary use is for personal 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 of the applications that will come with the core technology.

We show below the working of the prototyped product using the graphs of the measurement results plotted against the days of the menstrual cycle – and compared with the woman’s basal body temperature for reference. The graphs of the measurement data 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 menstrual cyclic profile has numerous repeatable features. It is an electronic signature of the menstrual cycle, which is the female 5th vital sign.

2. The range of measurement values 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 cycle phenomena (folliculogenesis).

The significance of these menstrual cycle profiles goes beyond reproductive management.

To wit: Ours is a unique and disruptive technology.

Note the planned 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 medical 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 http://to.ly/9WtG; BMJ editorial comment http://to.ly/9WtI; CNN.com article “Miscarriage?

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.

This blockquote is added in April 2017

Ovulona - single slide 3-day fertile window

ovulona-single-slide-3-day-fertile-window-forexs.pps

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 hypothesis (i.e. for the working hypothesis of the 3-day fertile window), see https://biozhena.wordpress.com/2007/12/03/fetal-sex-preselection-%E2%80%93-illustrated/ 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.

oh yeah

You need to know for sure. Day 1, day 2, day 3. Simple.
