Lenneth, no doubt environmental chemicals play a role, but transgender people have existed back to ancient times. It's a natural variation in the pre-natal development of the fetus. Like O'Hanlan says nature does everything on a spectrum. We have to stop thinking of gender variance as a defect in people. It's not.

Forgive me if I am wrong , but my understanding is some have slight gene variation while others are affected during foetus development by mother's hormones . I do believe I have read somewhere that this became evident during ww2 , when pregnant women suffered extreme stress .
