Theoretically, both women and men should have full breasts capable of producing milk. Nipples are one of those elements that are limited in formation in men at an early stage. That is why they in the future cannot find their completed appearance, and also can not fully function (as in women).
Dr. Mackaven from New York says that the presence of nipples in men indicates the fact that the initial plan for building women and men is very similar. But the muscles of the male chest have no functional significance, except that it serves as a barrier to the lungs and heart from damage.
Dr. McAven claims that nevertheless, 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 with male alcoholism.
It seems that both men and women have repeatedly asked themselves the question of why men need nipples? Do they really do not need them? But there are no and cannot be unnecessary organs in the body. But for some reason, nipples in men never had any important value, therefore, at first glance, they are completely unnecessary. So all the same, why do men need nipples?
Common but Incorrect Versions
First version : for beauty. Naturally, a person without nipples will look somehow stupid, although this opinion was formed from a generally accepted norm. This is the first answer to the question of why do men need nipples?
Second version: vulnerability. They say that grabbing a man by the nipples, squeezing them and twisting, you can make him very painful. Again, one can argue with this version. After all, there should not be such organs that can be used to injure a person. On top of that, men can also inflict great pain - when
struck in the groin. After all, if you hit the penis or testicles, the pain will be clearly stronger than if you just pinch on the nipples. If you do not believe me, ask any man!
Third version : this is an erogenous zone. But one can argue with this version, because men have enough erogenous zones even without nipples. Moreover, not all men like touching this particular part of the body.
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 remained. Science, of course, does not adhere to this version, considering it pseudoscientific.
So why do men need nipples?
There is another answer to this question. The thing is that up to 10-15 weeks of fetal development, embryos do not have gender differences. Only at this period of intrauterine life does the hormonal background change, and then, based on whether the fetus is a boy or girl, there is a change in gender. But the nipples themselves undergo their formation much earlier than a change in the hormonal background occurs. True, this is rather the answer not to the question of why men need nipples, but about why nipples in the strong half of humanity are formed at all.
