don't forget the role heredity plays.. recent research shows that the gene for the androgen receptor is longer than normal in many trans people.
"Studies in cells show the longer version of the androgen receptor gene works less efficiently at communicating the testosterone message to cells,"
'More feminised brain'
The researchers suggest reduced androgen and androgen signalling contributes to the female gender identity of male to female transsexuals.

"It is possible that a decrease in testosterone levels in the brain during development might result in incomplete masculinisation of the brain in male to female transsexuals, resulting in a more feminised brain and a female gender identity," they say.

I'm not doubting you Stacie but do you have a link to the source of that info?
