Men have nipples because during the early stages of a fetus's developemet the sex of the child has not yet been determied so basically what nature does is give a child i the whomb the same basic things as the opposite sex same reaso why women are able to have a orgasm.....(sorry if that didnt make any sense
Agree. Even sillier, my big fat cat - he has 8 of 'em! Go figure. (Actually, in the womb, most mammals are sex-less, with nipples, until certain hormones kick in, in utero, that make them/us female or male. At puberty more hormones surface that help finish the process.)
The early fetus is basically female. When the development advances to the point where the X and Y chromosomes are accessed, the sex of the fetus is determined and continues to develop in that direction. Its all about the DNA.
