I honestly doubt everyone with an older brother is gay, thats messed up logic.
I have heard about this before. If it actually has an effect is isn't by much.
Only 52% in certain cases....lol
Weird science there but I have seen some even worse so eh.
That's really not that far fetched. We know that sexuality is genetic, and we know that a whole heck of a lot goes haywire during gestation. We also know that a mother's womb does all kinds of super duper anti-everything to protect the life inside.

But it is so separate! How would antibodies affect someone's genetic disposition? Development at a genetic level doesn't seem that it would be affected by something on that scale.
I don't know about antibodies but I do know that the hormone levels in the womb can affect the baby's development. The main effect for that usually ends up being in the brain.
I think it's clear that genes only play a partial (although significant) role in ones sexuality, or else the 52% would be much higher.
B/c OB, mental development.

I am still perplexed despite your elaborate explanation. Could you explain a bit more for the slow?

I read somewhere recently that the amount of testosterone and/or other hormones decreases with each successive pregnancy, and that may play a role...
