A member asked:

If nipples are for breastfeeding a baby, so why do men have them?

Dr. Elizabeth Wallen answered

Specializes in Pediatrics

It's embryology: All humans start off as essentially female in the womb no matter what your chromosome arrangement is. After several weeks, if you have a Y chromosome, testosterone kicks in and it changes the chemistry in the genitals and the brain. But the nipples are already there...so they stay.
