A few more peri-vernal equinox tweets on #conceiving, #fertility, achieving #pregnancy & #baby gender contrary to Shettles

While NFP users know that fertility awareness is a must for birth control

We all know that the peri in the title does not refer to any “one of a large group of beautiful, fairylike beings of Persian mythology…”. We know that “peri” is in fact a prefix meaning “about” or “around” and “near”, appearing in loanwords from Greek, such as in the title here [http://dictionary.reference.com/browse/peri].

And now for the last few tweets; again somewhat edited, since here we do not have the 140 character limit. And again with clickable links to further information, including the #hash tags with all sorts of tweets there by anybody using a given hash tag, in the manner of the Twitter social networking mechanism.

These tweets should do it for this departure into the so-called microblogging. Do check out http://to.ly/VCF for what a reliable #fertility tool is about. Read up on it http://to.ly/vUz

Here is a birth control product that will be in the competition category when we go into the birth control market: http://twitpic.com/1971ez – This is the device used to insert the ‘Mirena’ coil into the patient’s uterus. Sent via TwitPic. Retweeted by you and 1 other. The reason why this was re-tweeted by yours truly was to highlight the invasiveness of the pictured device, which bears no comparison with ours (quite apart from our device not inserting into the uterus). But, of course, our product is not out yet, with all its user-friendly and otherwise beneficial attributes. Any comments, dear reader, would be appreciated.

RT@pregnancyorg: Read about your cycles getting #pregnant before #conceiving http://ow.ly/1l765 — and then I suggest you also read http://to.ly/VCF and http://to.ly/vUz

RT@Averyugya81: ARTs [Artificial Reproductive Technologies] for #infertility treatment may pass on genetic defects – warns ART pioneer http://to.ly/1pOJ . This is reminiscent of the development when Father of the Pill Dr. Djerassi turned against oral contraception, promoting instead what he called “the Jet-Age Rhythm Method”, by which he meant fertility awareness (aided by technology, hence the reference to jet age)

RT@Averyugya81: How often do I have to have sex to get #pregnant? http://to.ly/1pPi

Adam and Eve by Tamara de Lempicka - solarized

How often?

– Every day for 20 days with 69% chance of success, write statisticians http://to.ly/1phs (from day x to day y of your cycle)

If this continues to be pleasuresome, carry on for months on end to overcome the odds. Else, you need focus, and see my earlier tweets. Fight statistics! (With pleasuresome determination and with the aid of a deterministic timing tool… in the offing)

Again: The odds are against us! #pregnancy #birth control #fertility #startup angel-investor-find-and-match… same difference! Odds are very low (without that focus)

@pregnancyorg‘s gender selection http://to.ly/1qkx seems to perpetuate the Shettles recipe. However, evidence http://to.ly/1nyK http://to.ly/1qmz contradicts Shettles (whose claims have the reputation of not being backed by or based on any properly designed clinical studies). Here is a summary of a solid study, which – for the lack of “Perfect” – employed three “Imperfect Measures” of ovulation as defined in the previous post. The three gave similar results. Female births at (or near) ovulation, male births 2 days earlier (or so)

Birth distribution by gender - France et al., focused NFP TTC study

The uncertainty expressed by the “or near” and “or so” is the consequence of the “Imperfect Measures”, but the trend is clear. Also rather clear is that the low birth counts flanking the high ones are data outliers due to measurement errors inherent in “Imperfect Measures”. For more on this, go to the earlier post at https://biozhena.wordpress.com/2007/12/15/fetal-sex-pre-selection-%E2%80%93-the-fundamentals

Baby gender pre-selection will require a clinical study as stringent as the France et al. study was, but performed with our Ovulona instead of the inaccurate methods (BBT, Peak mucus, LH rise as opposed to LH surge apex)

RT@BabyMed: So can you get pregnant from having sex on your period? http://bit.ly/29yLQJ — THE absolute requirement is a RELIABLE #fertility monitor. (Persistent monitoring in the interest of evidence-based medicine)

RT@BabyMed: So can you get pregnant from having sex on your period? Yes, but only if the cycle is very short, which would be due to a very short follicular phase, which you can only detect with a RELIABLE monitor. (Not to track merely one, two or even three hormones in body fluids – you need to follow FIV™, Folliculogenesis In Vivo™)

RT@bioZhena RT@BabyMed: Furthermore, you want our built-in #pregnancy detection because it will see you #pregnant right away (not only about two weeks later), and – importantly – our device will also see if the pregnancy is lost, which happens quite frequently. See  https://biozhena.wordpress.com/2010/01/10/about-the-added-bonus-of-folliculogenesis-monitoring-automatic-pregnancy-detection . Early embryonic mortality is very high (according to some sources significantly more than 50%), and most of the losses of the conceptus occur early on, prior to 12 weeks. Mostly they occur sub-clinically, without the knowledge of the mother (by one expert source, 52% of all women who conceive experience early miscarriage…)             

RT@bioZhena: RT@BabyMed: Can #pregnancy result from sex on period? Yes, if it’s a very short cycle (due to a very short follicular phase) – which is unlikely – as the pre #ovulation phase is rarely that short. Since teenage cycles tend to be irregular and often short, this is of particular interest to sexually-active teens.  You must MONITOR your cycles if you don’t want any such surprise

RT@bioZhena: RT@BabyMed: Can #pregnancy result from sex on period? See here how unlikely it appears http://to.ly/1k9L . Unlikely, if the shortest follicular phase is 6 days. Menstrual bleeding would have to be as close to ovulation as 4 days, to make the answer unequivocally positive; that would mean cycle length of 18 days (or 16 to 20 days). Very rapid dominant follicle maturation. Until this (shortest follicular phase question) is investigated with our Ovulona monitor of Folliculogenesis In Vivo™ [FIV™], there is probably little data to invoke. I would be interested in any evidence.
