Considering male and female is a spectrum and biochemically, we
have the same stuff inside, just of different levels at
different times of the day. If I drink coffee or cocoa, I get
more copper which increases estrogen making me slightly more
female. If I eat pumpkin seeds which have zinc, I become
slightly more male because zinc leads to testosterone.
Outside of the child-bearing capacity which comes from having
formed those particularly shaped organs, ovum? or testicular
sacs? Does your thingie go in or does it go out? ... not a heck
of a lot of difference.
Socially? Usually a big difference. Training begins at babies.
Gets worst around 8 yrs old and it's downhill from there.
