Why do men have nipples ?

Some say that nipples in men is just an evolutionary baggage and believe that men once used to feed babies. Some say that it is just for looks, else the chest region would look empty. Most of such talks don't really make an intellectual person believe them. So we decided to know the real motive behind men's nipples. The facts that we got are really interesting and make us understand the human body better.

Men and Nipples ! What do Science say ?

In the beginning as the embryo is formed inside the uterus, you can't determine its sex, as it is neither male nor female. By that time nipples have formed. After 6 or 7 weeks certain changes occur, which determine its gender. If it is going to be male, then testes start to form and testosterone hormone begins to produce. It is the testosterone hormone that makes a male from the uni-sexual embryo.

According to one more scientific hypothesis, we are all females inside the mothers womb for upto 7 weeks. After than the Y chromosome develops in some embryos to make the male. By that time nipples and some undeveloped breasts have already developed. Even the labia and clitoris have also formed by that time. But as the testosterone hormone production starts, labia fuse to become scrotum and clitoris develops to become penis.

Why men can't feed a baby ?

Nipples in men as just dummy and can't produce milk. Prolactin hormone in females stimulates lactation and milk is formed inside the breasts to feed babies. Absence of this hormone in males makes men incapable of producing milk.

Can a man lactate ?

Yes, in some very rare cases it has happened. It happens only when pituitary gland in males secrete prolactin hormone, which is responsible for lactation in women. In 2010 a study was published where a man lactated due to pituitary tumor. Normally a woman have double amount of prolactin hormone in her body compared to man. During and after pregnancy this amount can become 10 times which makes a woman lactate. It means that a man needs 20 times more prolactin to be able to lactate which can happen only under certain rare medical conditions.

Can a men have breast Cancer ?

Yes, however the chances are very rare. Only 1% of all breast cancer cases happen in men. It is because men have underdeveloped breasts under their nipples. Obesity play an important role in developing breast cancer in men.

Those of you who feel more proud to be a man should must know that once you were a baby girl and god left you with those non-useful nipples to keep you reminding of that.
