why do men have nipples ?

Answer 1

apart from the pleasure we get and that we'd look strange without nipples? :)

In the early stages of life from conception until about 14 weeks, all human fetuses look the same, regardless of gender. At the tender age of 14 weeks post-fertilization , genetically-male fetuses begin to produce male hormones including testosterone. These hormones turn the androgynous fetus into a bouncing baby boy.

Here's where the developmental clock comes in. By 14 weeks, when the hormones turn on, the nipples have already formed. So, while our male fetus goes on to become a baby boy, he keeps his nipples, reminding all of us that people, male and female, started off the same way.

Answer 2

Its because in the early stage of a baby in the womb it is not a boy or a girl... its only afer a few weeks that the sex of the baby is decided. There is a book called 'why do men have nipples' and it has many questions like that in there

Answer 3

I read an article on the Internet about rare cases that men breastfeed their babies. The article was about a man in Indonesia whose wife died shortly after giving birth to their baby. To comfort the baby he held the baby close to his chest, of course the baby found a nipple, started sucking and stopped crying. He kept repeating this and soon afterwards noticed that he was sort of developing breasts and had milk production. According to this article there were more registered cases like this..... Sorry can´t remember where I read this and of course, whether this is true, but it sort of makes sense: why else....?

Answer 4

Nipples develop before the gender of a baby is decided.

Answer 5

Until quite recently (about 300 million years ago) our ancesters were all genetically "female" with "XX" chromosomes. A mutation "male" gene appeared, which caused a beneficial diversion. Over millions of years the masculine "Y" chromosomes developed individually, with genes defining masculinity.
Human males have both X and Y chromosomes, the Y "male" chromosome only has about 83 genes, whereas humanness in general is defined by the 1,000ish genes in the X chromosome.

Answer 6

Well obviously not to breast feed, Ha!

...Interestingly a women has a Penis equivalent "clitoris" so maybe male and female are not so different...

..another theory, just as some fish can change sex according to the needs of the population, maybe humans had that capacity many years ago. In that case the breast would grow...I guess

Answer 7

It's like cars that don't have electric windows but they still have the controls for them.

Answer 8

So that they don't look like a bit of an alien without them!

Answer 9

when we were in the womb we all started off as female, and due to hormonal changes or somwhat you changed to male, so its just a wee reminder that you were female

Answer 10

cos when babies are conceived, the foetus always starts off as a female..until the later stages in pregnancy when the baby's sex is decided.
