It could be a hormonal thing. I remember seeing a documentary once where a woman, who was having fertility problems, found out that she was genetically a male, that is, she had XY chromosomes. It seems there was some problem that inhibited either the production of testosterone and/or progesterone, or the ability to metabolize them. She completely identified herself as female, and had no clue until she sought medical advice!
