Shettles die-hards

[atomic sagebrush]

It is BEYOND frustrating to me because the evidence so firmly points away from Shettles working. Both Tamara and I (and literally every scientist that has ever studied it including Valerie Grant) are adamant that it has been completely proven wrong that "X are big and slow but live a long time" and "y are small and fast and die sooner" We know 110% that Shettles was mistaken when he looked thru the microscope and saw X and Y sperm (that were really capacitated and uncapacitated sperm) and if Shettles was alive today I feel very confident he would have come around to our way of thinking with this new evidence. But, it just keeps hanging on.

The really frustrating thing is that so many people don't even have a clue what day they Oed on anyway. So they look back and they're like "yeah I got Billy Bob on O day, and Bobbi Sue 3 days before O" and we have NO WAY of knowing if that is even true. People look back and assume they did because, Shettles.

But, this is one of those things that I have had to accept is my way of "roling a boulder up a hill daily only to have it roll back down again the next day" and I hope over time it does start to become more recognized that it doesn't work.

Yes I've learnt the hard way haha. I guess I'm hoping one or two of them who are serious about swaying may take a look. I wish I had understood it properly years ago!

Sometimes you have to post for the people who AREN'T saying anything. Remember there are more people reading then there are answering and it may be many of them are sitting there thinking "this doesn't add up to me" and then you may have really helped them out quite a lot. Thanks for sharing the info too BTW!!! i really appreciate it.

True true. No worries, thank you for starting this site and doing countless hours of research etc, it's amazing.

And I did want to mention that we've had an influx of new people the last several days so you may very well have done that!! Thank you.

This drives me insane too. All of the research on the topic has disproven Shettles. Every single study. Either they find no difference or they find the opposite of Shettles is true. Sex on ovulation day leads to more girls while sex farther from ovulation favors boys. When I was trying to conceive my first I read this book called The Impatient Women's Guide to Getting Pregnant (great book, by the way, for getting pregnant and has a great chapter on gender selection), which is written by a psychology professor, who basically does statistics for a living. She did a meta analysis of all the studies and did find a statistically significant difference favoring the opposite of Shettles. The theory posited in the book is that most embryos conceived on ovulation day were miscarried so it makes sense that the girl embryos, which are heartier, would be more likely to survive under circumstances when miscarriage is likely.

I also agree that most people don't know when the ovulated so they just assume their baby was conceived in line with Shettles' theories. Even with temping and ovulation prediction kits there is room for error. This is also why so many people believe moon sign theory works, another thing that drives me crazy. As difficult as it is to pinpoint ovulation, it's even more difficult to pinpoint conception because conception happens within 24 hours of ovulation. So people have a 48 hour window for ovulation (if using OPKs) and then a 24 window for conception, which means there's a 3 day window and with moon signs a difference of hours, let alone days, can change what you're supposed to be having. But people swear up and down that they're sure they conceived under the correct sign for the gender of their child.

This is a really interesting read. It claims that female embryos are more fragile than previously thought.

I personally believe this is a skewed study because the info that they used was from abortions and fertility treatments. I wish we had a more effective way to study it because the truth is we really have no clue if EITHER girls or boys are heartier/hardier (am I the only one who is not quite sure on the grammar there LOL)

Thanks for sharing glowbug and welcome!

totally about the moon signs don't even get me started. Like anyone knows the hour of their conception. One of these days when I'm really bored I'm gonna take the mystic methods apart but it's so stupid it gives me chronic facepalm just thinking about it.

I have a different take on the O and O-1 day bump with girl conceptions (which I concur does seem to be the case based on my analysis of studies as well). I believe that reduced fertility and harsher maternal conditions AND poorer sperm health = more girls conceived and since sperm lives a shorter time in harsher conditions (both X and Y) I suspect that people who may not be ABLE to conceive from 2 or 3 days before O, may be more "set" for pink. Thus, they can only get pregnant with attempts that are pretty close to O. And the people who are superhuman and can get pregnant from 4 days before O are probably high sperm health/high maternal conditions couples.

Yeah that makes total sense. I've always wondered about those super human freaks who claim to have conceived from, like, 10 day old sperm or whatever and think well, it must be a cosy environment in there if sperm can survive that long in it!
