Why is it more likely for 3 of the same sex???

[ladybirdflies]

the first two girls were 2 1/2 years apart but then I had a six year gap before another girl, but with a different partner. My ex is a chef and apparently chefs are more likely to father girls because of the heat near the testies. I assumed after two girls and a new partner I would have a boy, but no, my biggest surprise happened another girl.
Then I started to wonder is it my body that favours female sperm?? I recently had two mc and started to wonder were they boys and I could not carry them??? We will try again soon, and I really would be chuffed either way, how amazing to have four of the same sex.... and how amazing a boy after all these girls... I do find all of your replies very interesting indeed!

This is genetics at work and unfortunately us girls have no say on it. Geneticists think they have found a gene that has three alleles that explains this. It means some guys have more male than female sperm, the opposite, or a 50/50 split. The beat way to predict it is to look at your partners family tree. Look at him And his siblings, more boys than girls, girls than boys, or even? And you can also look at his fathers siblings for the trend, and also any brothers of your partner that have children. It gets more complicated and hard to see in small families, and those who have needed ART. My partners family are 50/50 but he is in a stressful job and exposed to radiation on occasion, so my guess would be that we are more likely to be girl producers. It's also a noted trend in the defence forces to have more girls..... we have, out of the 8 babies born to friends, never seen a little boy!

I think that some men just have more boy/girl sperm and some have 50/50 too.

That said, we have even amounts of boys/girls on both sides of family (including hubby and I having 2 sisters and a brother between us) and yet we have 3 boys!

Ive heard the chances increase but never seen the studies behind it, we tried swaying number 3 but odds must have been too high already
