why have men got nipples??

Answer 1

because every growing fetus is inherently female. It just takes that one different chromosome to make it male.

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.

Evolution may hold an answer

But why hasn't evolution meant that men have lost these nipples? Over the millennia the human body has been adapted and shaped by what makes one man more successful than another.

Having breasts and nipples - being able to suckle the young - may have conferred an advantage over those men who couldn't. For example it may have increased the chance of survival in lean times if the father could feed the babies as well as the mother. Conversely it doesn't seem to have been a disadvantage - nipple disease in men is very rare. Because nipples in men don't cause problems, there's no genetic drive to lose them.

Answer 4

Men have nipples because during the first 6 weeks in the womb every baby is essentially the same--that is, female. The Y chromosome doesn't "kick in" until about 6 weeks after conception. Therefore, because every male was a female for 6 weeks in the womb, they were left with nipples...

...much like a souveneir.

Answer 5

Well actually it is the female that got the nipples from the male since the male was created first.
Like they said we would really look funny with out one, that is sort of like asking did the first man have a belly button

Answer 6

we all start out in a similar way in the embryo. During development, the embryo follows a female template until about six weeks, when the male sex chromosome kicks in for a male embryo. The embryo then begins to develop all of its male characteristics. Men are thus left with nipples and also with some breast tissue.

Answer 7

Ha-ha-ha! Some good answers on here but it's true about the Y chromosome and all that biological stuff...

Personally... I would say they are there for women to give you a hard time when you misbehave and to pleaze when you don't!

Don't you like getting your nipples licked?

Answer 8

Of course we are humans! Even animals have a nipples to...

Answer 9

Maybe they obtained them through thousands of years of evolution in preparation for them to be the next generation of child bearers. Man if I could live long enough to see that first hand!

Answer 10

No one really knows, however it's generally agreed that nipples are sex-neutral elements of human beings.

Answer 11

When everyone is conceived they're actually female for the first 2 weeks
