Why Do Men Have Nipples

Why have male nipples not dissapeared?

There seems to be a logical explanation about why women have nipples - for babies. But why do men's bodies retain what appears to be redundant body parts? The Darwinian natural selection process would seem to dictate that male nipples really should not be there. So what's the deal? Why do men have nipples?

The answer is that as embryos men and women have similar tissues and body parts. If anything the embryo follows a 'female template'. That is why nipples are present in both sexes. It is the effect of the genes, the Y chromosome and the hormone testosterone that brings about the changes and masculinises the embryo. Testosterone promotes the growth of the penis and testicles. Because nipples are there before this process begins the nipples stay!

Nipples and breast tissue have no function as such except for perhaps protecting the heart and lungs from injury.

okay, i know this sounds gross.

but like it or not, it's for my Anatomy class.
