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

Actually sperm count is 50/50 x and y in equal amounts. For sperm to form it needs to split from a parent sperm cell that contains both an X and Y chromosome. There is a website that has debunked a lot of the myths around gender chances.. I think it's called gender dreaming or something. It was actually very interesting and put a lot of the current theories (genetics, family history,shettles, O+12 mothods) under the microscope and pretty much proved them all wrong.

Interesting BlackRose, do you have a reference or link to that study? I'd love to read it.

I don't believe that is true. I did research into this when we were expecting number three after already having two children of the same gender.

Not all men produce x and y sperm in equal amounts. Some men do, some men produce more x than y, and some men produce more y than x.

You are more likely to have three of same gender if your first two children are boys as nature slightly favours baby boys.
