Isha,
I don't want to side track the thread too much but has any research been done on primates as our nearest descendants ?
I apologise that maybe I should have done some research but are humans the only ones to have this level of gender anomalies ?
I've always been intrigued by the fact that after WW1 the birth rate for males in France was much higher until a natural balance of male to female was achieved . So what influences the reproductive system to achieve that ? I also read in a paper that homosexuality varies depending on the the birth rate ! I have doubts about that one because some countries struggle to control their birth rate !
I suppose the point I'm making is are the differences in the brain arbitary or is there something in natural selection ?
The bottom line is we are not lying when we say we can't help our Cding. we are somewhere between male and female ! The feelgood chemicals released by our dressing are superfluous to where we are on the gender line !
