Reply #19: all embryos start out female until the "hormone cascade" at about 6 wks (I think)

That's when the xx or xy chromosome asserts itself and changes the genitalia from female to male..

I just wonder what the overload of male hormones taken (to produce a beard and suppress menstruation, would have on a developing fetus..

I guess they will know soon :scared:

but maybe not until the child reaches puberty
