Hi Girls,

Bec, I've also heard that IVF favours males and yes, as Heather said, there seems to be a predominance of them among those of us who have had IVF. Could just be a coincidence though.

The theory is that the male sperm swim faster and so get there first. The girls are slow and steady. This theory underlies the advice given to those trying to select the sex using natural methods (ie, Shettles). It's all to do with the timing of intercourse and ovulation. Apparently if you want a girl, you need to DTD a few times over the days leading up to ovulation so that there are plenty of girl sperm up there waiting for the egg. If you wait until right on the day, the boy sperm have the better chance.

I'd also heard that ICSI tends to produce more females but I am not sure why this is. Carrie from LTTTC had ICSI and hers was a little girl. Bec, now you're another one I've heard of!

The doctors will always say though that it's still just a fifty fifty chance in the end and of course they're right but it's fun to speculate anyway!
