Question: What is the purpose of nipples on males?

Hi ExplosionsGolor_00

I don’t know whether this will come as a shock, but in the womb all embyos start off as female. For the first few weeks the foetus grows as if it were a female and reproductive organs and nipples develop. After about 60 days for those with a Y chromosome (ie males), testosterone kicks in which changes the genetic activity of cells in the brain and genitals…..but the nipples don’t disappear. So there is no real purpose for male nipples, they are just developed before testosterone kicks in.
