by hi Member since:December 26, 2009Total points:4,388 (Level 4)To tell you the truth, nobody really knows. The best explanation I've been able to find (and frankly it doesn't explain very much) is that nipples aren't a sex-linked characteristic. In other words, nipples are just one of those sexually neutral pieces of equipment, like arms or brains, that humans get regardless of sex. 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!

Member since:March 01, 2011Total points:564 (Level 2)For the first 2 months after conception, all fetus's are the same, male/female. Its only after that that they develop their x/x or x/y chromosomes. (x=female, y=male). So because everybody has an "x" chromosome, males and females share some parts, i.e; nipples. by Chris Member since:July 30, 2008Total points:397 (Level 2)Men have an X and a Y chromosome. They have nipples because of their x chromosome. They are unable to produce milk like females because of their Y chromosome. Females have 2 X chromosomes and no Y chromosomes, so they are able to produce milk.Imagine a guy without nipples. It would look really weird.
