I thought female ovaries created the x chromosome and the male sperm then either provide the x or the y. Why then do people say the left ovary creates more girls? Surely whether it's left or right shouldn't make a difference?? My left ovary doesn't really work (confirmed by two different doctors) therefore I only seem to ovulate from the left and am now, after what I thought was a pretty good sway, expecting my third son. Am I destined then never to have a daughter??
There is ~some~ evidence that an egg produced from the left ovary = girl and an egg produced from the right = boy. BUT there is also evidence that we almost always produce an egg from the right and the left is only for "backup". All conflicting, and confusing.
I bet it's just different for everyone. On all my monitored cycles so far, my largest follicle is on the left, and on all the pregnancies where I've had the corpus luteum's location confirmed by ultrasound, it's been on the left. These have been boy and girl pregnancies both. It does seem that my left ovary is larger, more active, and more likely to ovulate. But does this really have anything at all to do with the genders of the children I conceive?
ok thanks ladies for your replies. I have just got confirmation of boy three is on his way and just trying to work out what went wrong as I felt I had a pretty decent sway behind me. Certainly there were a lot of things different this time regarding Dh and my diet and supplements and frequency of bd. I am just now thinking maybe it's hormonal and I am predisposed to conceiving boys! I know I have a low progesterone level as well as the left ovary not working maybe this all led to boy number three. Thanks again!
I was born with only my left ovary & I have 2 boys!
Maybe I'm not understanding this correctly, but if this were true, wouldn't HT gender selection be as simple as only retrieving eggs from the "correct" ovary?
It's by no means 100%, and really the evidence just says that "more" female pregnancies come from the left ovary.
I ovulated from my left ovary with this pregnancy and I'm having a boy.
If you can bear with me this is one of my essays I am going to write hopefully within the next few days.
Yes, and that this doesn't work is a pretty strong indication that there is something else going on and that the side of ovulation is really a red herring.Quote:

Well, good, because my dominant follicle is on the right this time (for once!) and I'm swaying pink.
so i never did manage an essay about this but did put it into my new book.
the evidence indicates that when you ovulate from left, hormonally you are different than when you O from the right. This has nothing to do with the ovary or the eggs themselves, it's that overall you have different hormone levels going on and this affects lots of other stuff in your repro tract as well, particularly CM and it's probably this which sways gender.
In the studies it wasn't side of ovulation per se, but it was the side of ov. over a 3 month time period. And the combination that was the most likely to alter gender ratios (which was L,L,R) was only 75% likely to produce boys, still 25% likely to be girls. So many exceptions, it's interesting because of waht it tells us about gender ratio but DOES NOT mean that you can only get girls from the left.
I o 75 % of the yome from my left for years and years and have 3 boys and only 1 girl!
