Interesting facts: why do men need nipples?

Theoretically, both women and men should have a full breast, capable of producing milk. Nipples - this is one of those elements that are limited in the formation of men at an early stage. That is why in the future they can not find their completed form, and also can not function fully (as in women).

Dr. McEwen of New York says that the presence of nipples in men indicates the fact that the initial design of the structure of women and men is very similar. But the muscles of the male breast have no functional significance, except that it serves to protect the lungs and the heart from damage.

Dr. McEwen argues that after all, male breast tissue has the ability to respond to female hormones. This example can be seen with gynecomastia, which appears with an excess of estrogen in the body, and can also be observed in male alcoholism.

It seems that both men and women have often asked themselves the question of why men need nipples? Do they really need anything to them? But the body does not and can not have unnecessary organs. But for some reason, the nipples of men have never had any important meaning, so, at first glance, they are completely unnecessary. So all the same, why do men need nipples?

Common but incorrect versions

The first version : for beauty. Naturally, a person without nipples will look somehow stupid, although this opinion was formed from the generally accepted norm. This is the first answer to the question of why do men need nipples?

The second version : a vulnerable place. They say that grabbing a man's nipples, squeezing them and twisting, you can make him very hurt. Again, this version can be argued. After all, there should not be such organs that can be used to injure a person. In addition, men can be hurt and worse - with a blow to the groin. After all, if you hit the penis or testicles, the pain will be clearly stronger than if you just pinch your nipples. If you do not believe me, ask any man!

The third version : this is an erogenous zone. But with this version you can argue, because men have enough erogenous zones and without nipples. Moreover, not all men like touching this part of the body.

The fourth version: some people believe that in ancient times all people were hermaphrodites. As a result of evolution, people acquired sexual characteristics: in women, the breast functioned to feed the baby, and in the male half, it simply stopped developing. But the nipples stayed. Science, of course, does not adhere to this version, considering it to be pseudoscientific.

So why do men need nipples?

There is one more answer to this question. The thing is that embryos do not have sex differences before the 10-15th week of fetal development. Only at this period of intrauterine life there is a change in the hormonal background, and then, proceeding from the fact that the boy or girl is the fetus, there is a change in gender. But the nipples pass their formation much earlier than there is a change in the hormonal background. True, this is probably not the answer to the question of why men need nipples, but about why nipples in the strong half of humanity in general are formed.
