  1. very brief and simply to say : 1)like that fetus for a couple of weeks is sexless, and after a period of time, depending on the chromosomes it has XX, XY,.. male or female hormones play their role and make that fetus to mutate towards a gender? 2)in human anatomy penis and vagina , except the shape and functionality, are not different that much ! so as every thing else ! 3)due to that fetus being sexless times, a man has nipples, and woman got immature prostates ! are all of these generally ok?
