The story of a boy who was raised as a girl seems to show that gender really is all in the genes. Despite the efforts of psychiatrists, surgeons and parents, he never felt happy as a girl and eventually reverted to being a man, got married and is now living happily. [...]
Despite being raised as a girl, Joan never felt happy. At 12, she was given oestrogen therapy to complete the conversion to a woman. She grew breasts, but was never accepted by other girls, nor felt comfortable as a woman. [...]Dr Diamond says that the case history has implications for any child born with ambiguous sexuality. "Keep your knife away," he says. "Let the kids make a decision when they get older."
Michael Bailey, a psychologist at Northwestern University, Illinois, told Science Now, a daily science news service run by Science magazine, that the case was heralded by many as the pinnacle of proof that psycho-social factors could override biological factors in determining gender.
Textbooks continued to claim that Joan made a successful adjustment, in spite of contradictory evidence. Dr Diamond's report, says Dr Bailey, "suggests that, if anything,
how you're reared matters little".
