Bingo!

• Brain testosterone theory

Simon Baron-Cohen proposes a model for autism based in his empathising-systemising (E-S) theory^[8]. His team at the Autism Research Centre in Cambridge, UK, measured testosterone levels in the amniotic fluid of mothers while pregnant. This is presumed to reflect levels in the babies themselves. The team found that the babies with higher fetal testosterone levels had a smaller vocabulary and made eye contact less often when they were a year old.

His group has looked at the original 58 children again, at age four. The researchers found that the children with higher testosterone in the womb are less developed socially, and the interests of boys are more restricted than girls. The results are published in the Journal of Child Psychology and Psychiatry in a 2004 issue ^[9].

No they were not dropped on their heads. They produced too much testosterone while they were developing. That manliness that we love so much also inhibits them. We just can't win for losing.
