Variability of menstrual cycles and of ovulation timing

See how this complicates things whether you want pregnancy or want to avoid it

And yes, stress has something to do with it

In the previous post, I wrote that we would suggest that the terminology that speaks of sub-fertility or reduced fertility is misleading. If you did not stumble over it wondering why, then I am glad for you (I should say, for both of you!). Because you “got it” and will now think of taking some appropriate steps, and those will NOT be to your insurance agent and/or – more likely – to your bank!

Because you understand that, until proven otherwise, your situation should be termed one of “instant conceptive gratification cannot be had probably due to wrong timing”. Nothing reduced or sub- about that! And, the adjective “conceptive” is meant to indicate that the hope is that the other kind of gratification has obtained. The one I referred to as physio-pleasure, but that would be a topic for another time…

Let me remind you of the gist of the previous article with this picture. -

The collage is meant to be suggestive of the message from bioZhena. After some disappointments – if no steps were to be taken to determine the right time (aka kairos time, in the terminology of ancient Greeks) – with the help of our Ovulona you will get the pregnancy that you wish for.

This happy end is represented in the third part of the composite graphic, which part is what they call a wordle. It is a wordle of this here bioZhena’s Weblog, showing the first 15 most frequently used words in the blog as of a few months ago (the font size is a measure of the respective words’ usage frequency). I called the piece “15-Word(le) Greetings from bioZhena’s Follicular Waves”, as the waves are hinted at there, are they not. Learn about the follicular waves, or rather about Folliculogenesis In Vivo™ [FIV™], and you will get what you wish for.

Since you are not likely to have reviewed the menstrual variability references given in the previous post, I will document the notion of wrong time with our data. I mean the data from a small clinical trial carried out with a prototype of our core technology, the Ovulona™ for home use. This trial was performed by an independent group at Marquette University NFP clinic – with patients attending the clinic to learn NFP for one of two reasons: either because they experienced difficulties in achieving pregnancy, or because they wanted to learn NFP [Natural Family Planning] as a means of birth control. Or, maybe, they wanted to use NFP for both, at different phases of their lives.

We can look at data of 10 women, 2 cycles each, reviewing here the ovulation data obtained with said prototype of our Ovulona device.

The data are systematically documented (along with two reference methods for comparison) in the attached 1-page document (Variability of menstrual cycles), and I am doing my utmost to boil it all down for you to as brief a briefing as possible.

Listing of two consecutively detected ovulation days (ovulation marker detected by our device), and noting whether the cycle was subsequently categorized as regular or irregular, goes like this:

Ovulation day number in 2 consecutive cycles

Patient #1 16 (regular) 17 (regular) Patient #2 14 (regular) 17 (irregular) Patient #3 17 (regular) data absent Patient #4 15 (irregular) 14 (irregular)

The list goes on, and you should know that “irregular” means “challenged”, and means something of a problem that our modern lifestyle presents to the biology of our women.

One patient provided data from her four cycles, and the variability was – not surprisingly – even more pronounced (-5 days, +5 days, -3 days):

Patient #9

18 (irregular)

13 (regular)

Patient #9

18 (irregular)

15 (regular)

The following table shows the wide spread of the differences between ovulation days in two consecutive menstrual cycles of 10 women attending said NFP clinic.

Differences from -5 to +3 days are recorded in this small sample, and the one woman with 4 cycle records showed +5 days, too, which illustrates that the more cycles are followed, the larger the spread of ovulation days becomes (this is “cycle irregularity” in the conventional, usual sense).

Our meaning of regularity is indicated and documented in the attached summary, “Variability of menstrual cycles”. Regular cycles are those where our ovulation marker is within 1 day of LH peak or of the day of Peak mucus (Pk).

Our meaning of irregularity is defined as those cycles where the ovulation marker day data is not within 1 day of said hormone-detecting parameters (LH and estrogen, respectively), and is always higher – signifying delayed ovulation (delayed with respect to the hormonal signals).

As I said above, “irregular” in our parlance means “challenged”, and it means something of a problem that our modern lifestyle presents to the biology of our women. More often than not, the challenge is stress, which I discussed in this blog earlier in at least two posts. Our FIV technology (aka the Ovulona personal monitor) detects the effects of stress, and helps to deal with the consequences in terms of its effect on fertility status.
