>Science agrees. It has been scientifically proven that the brain and the hypothalamus is gendered within the first trimester of a pregnancy and that the gendered brain may not match the body's gender due to androstendione, a stress hormone similar to testosterone that binds to receptors that testosterone should have bound to creating a female hypothalamus in a male body, creating a third gender class - males, females and homosexuals.
I believe this has been discredited long ago. Some googling finds
"Although clear sex differences were evident, Swaab, Gooren and Hofman (1992) found no differences in the size of the SDN of the preoptic anterior hypothalamus between "gay" and "heterosexual" men, contrary to what the androgen underexposure theory predicts. Dorner's (1988) contention that "gay" men have a female hypothalamus was not upheld."
