Previous research had revealed the more older brothers a boy has, the more likely he is to be gay, but the reason for this phenomenon was unknown.
But a Canadian study has shown that the effect is most likely due to biological rather than social factors.
So is this why there seems to be so many gay boys that come out of large religious families? I wonder if we can use this little bit o'science to get the forced pregnancy wingnuts off our backs? "See I have to use birth control cause I don't want to make a gay baby"*
*Not that I have any sort of problem with gay babies or gay adults- I'm just playing with the homophobes folks.
