When the embryo is just starting out, the sex has not been determined, this dosen't happen until later in the pregnancy, when the balance of hormones and chromozones determines it.
Until that time, the nipples may be required. During puberty, the changes in the child's body will trigger the growth of breasts for women. There are some cases when men do not produce enough testosterone and will grow breasts (though not full breasts) this can be quite devestating for an adolescent boy, but can be brought back with the use of medication.
And, besides, they come in real handy to locate where to CPR .

All embryos start out as female, the ones with a Y-chromosome become male when an enzyme switches on. So, basically, men have nipples because women need them.

Nipples in men are considered a vestigial organ, like your appendix. Discover magazine had an article about this w/in the last year...

every single embryo is female until is about 6 weeks, when some turn into males . . the nipples develop before this . . if the embryo turns female they turn into lady bumps and if it turns into a man they just stay there and dont do anything! simple!

They are an erogenous zone, that's what they're for, I think.
