The physiological purpose of nipples is to deliver to the infant milk produced in the female mammary glands during lactation. In the male, nipples are often not considered functional with regard to breastfeeding, although male lactation is possible.

At conception, a human has no gender. It isn't for a while that gender is determined. Nipples are a bodypart that comes during the time before gender is determined. In males, they remain undevelopped. In females, modified sweat glands produce milk when the woman is of age for pregnancy.

the nipple forms before the sex characteristics are expressed in gestation and development. It is more energetically expensive for the body to reabsorb this structure once the male characteristics are expressed than to just leave them alone

this website suggests that men can breastfeed in a pinch, thus the need for nipples (if thier mate dies, whatever) but that notion really grosses me out.

No purpose. Mother nature is just lazy and does not want to add all that DNA that would be required to make them appear only on women, so they are suplied to everyone, need them or not.

When you are in your mom, you are set closer to a girl, then a boy, so when a gene gives another chemical, you become a boy, but you still have niples
