Most men also have nipples. Can men breastfeed?

Limited to the "nipples" of male animals, male cells must have something to say. Many people are always annoyed by these two points. Occasionally, the nipple will be impulsive if it is not careful, which will destroy the complete aesthetic feeling; Male runners who love marathons will bleed if they don't take care of their nipples. When playing basketball, people who are a little fuller will also be laughed at for their big breasts.

In this case, 25-year-old Xiao Wang is worried about his chest. He is a sunny and handsome young man. Somehow, in a year's time, his weight soared, and even his chest grew bigger and bigger, and he could ooze milk, which once made Xiao Wang very ashamed. Such a scene broke out in girls, and the conclusion is not enough. Vaguely, breasts and nipples are special parts of girls, which not only give enough points, but also give women the opportunity to be mothers and feed their babies.

About the seventh week of embryonic development, sex chromosomes begin to develop efficiently. At this time, embryos with Y chromosome, under the action of SRY gene, began to produce structures with male characteristics such as testicles, rather than individuals with this gene, and developed organs with female characteristics according to this plan. Why not remove this feature in an evolutionary way? If we are not sure that a feature is limited to our existence, it is likely to disappear in the process of evolution. But in fact, besides nipples, there are many unnecessary physical features.

These features are generally called residual features, which are left over from the development of a species. Not necessary, but because of the figure, the retention of these features is inefficient, so the figure is automatically ignored, and there is no need to care about whether the nipple is removed or not. Second, who says nipples are useless? Common in women, the nerves of male nipples are aggregated, which means that their sensitivity is not lower than that of women and they are easily stimulated. And two points, close to the scale, take care of the navel, a little aesthetic. The most closed is that male nipples may also produce milk, as Xiao Wang said at the beginning.

As long as you promise, men may breastfeed like mothers. Generally speaking, men will not breastfeed, but if they are affected by the efficiency of prolactin, they can explode milk. The situation of male lactation is mostly pathological, which is a disease, because drugs and conditioning scenes lead to the decrease of male-related hormone content, while the decrease of female-related hormone content leads to it, which is called "male mammary gland development disease". But some people are especially good at it.

Overseas, a husband died unexpectedly because of his muddy family. In order to cultivate my young children, he took special measures to let me breastfeed and cultivate my children. In the animal kingdom, there are also males who produce milk, such as brown fruit bats, and male goats occasionally produce milk. Finally, male nipples and breasts are enlarged, which is basically consistent. Especially newborn boys, because they grew up in their mother's womb, are born with a little breast structure, and then they will gradually disappear.
