why do men have breasts and nipples?

Answer 1

Favorite Answer

Men don't develop breast tissue, but they do have nipples. All humans at one point in time are a woman. It all depends if the Y chromosome is present or not. If it is, the body sends out testosterone changing the woman to a male. The organs "down there" change to male organs, but the nipples just stay where they are. So in a sence, men have nipples because women have them.

Answer 2

when a baby is first developing in the whomb it is female, so nipples grow, after that the baby will either become a male or stay female... thus meaning males and females have nipples because all males used to be female, after that its all up to hormones, female hormones cause breasts to grow etc, and males hormones cause lots of hair etc
