Why do men have nipples? ?

Question

Seriously - what purpose do they serve?

Answer 1

Actually, men can breast feed. It sounds weird but back in the day if there was no women around we(men) where able to produce milk. You can still do it but you have to get special hormones from the doctor.

Also, women mostly breast feed becuase when they are going to have the baby they are already producing it cause their body knows.  

Answer 2

s*x is determined by the X and Y chromosomes- the mother provides one X chromosome while the father provides either an X chromosome or a Y chromosome.

XX= female

XY= male

XO= does not have a s*x BUT physically the body looks female (default s*x)

Because the default s*x of a human fetus is a female therefore both sexes have nipples. Also mens' chests would look unnatural if they didn't have them. There have also been a few cases of a male being able to breastfeed.
