embryos are all female to begin with only when the Y chromosomes kicks in do the penis and testicles develop.....all human share many similar features including nipples...only the sex hormones control and separate the male from the female....

I don't think anyone really knows. It seems that, Human nipples appear in the third or fourth week of development, well before the sex characteristics. (The sex hormones start to assert themselves at seven weeks.) As many as seven pairs of nipples are arranged along either side of a "milk line," a ridge of skin that runs from the upper chest to the navel.
Normally only one pair amounts to anything, but on about one baby in a hundred you can detect some vestige of the other ones, usually on the order of a freckle or a mole.

its just the way men are.i know that some men even have large enough milk glands to produce milk.however i dont think it would be good enough to feed a baby as i have read others answers.every mammal has nipples and thats just the way the species is.

all mammals have nipples, both male and female, good question. Could it be that male regressed as female took charge of feeding the offspring? ever heard ..."as useless as tit's on a boar hog"?

I've always wondered that myself. But, I think that men would look weird without them.

That's not the question. It is why do women have breasts! Why?! So they can, with their nipples, breast feed.
