why do men have nipples?

Answer 1

I'm not sure. Why do I have 3?

Answer 2

After conception the developing embryo follows a female template. It's only after six to eight weeks that the effect of a gene on the Y chromosome kicks in for boy embryos. This gene stimulates the production and influence of hormones such as testosterone, which 'masculinise' the embryo by altering physical development to form male features.

Nipples, however, are formed before this masculinisation process takes place, and nothing that goes on later reverses this.

So the story that God made Eve from Adam's rib got it the wrong way round. Males are an adaptation of females and the nipples are just one piece of evidence for this.

Answer 3

Basic biology, all embryos at conception are female and the body is designed thus. After a few weeks depending on which sex gene kicks in, the foetus continues as a female or changes into a male in which case changes occur to the genitalia.

Answer 4

As a part of evolution to mamals, all mammals have nipples, be it male or female. Therefore men too have nipples.

Answer 5

all humans develop in the womb in the same way until a certain point, at which point their sex is decided. this happens after the formation of the nipples, unhelpfully.

Answer 6

Decoration.

Answer 7

When you press the nipples together, that's how you make babies.

Answer 10

because they used to be female up to a certain point during growth in the womb.
