What is the use of men having breasts?

We all know the importance of women's breasts. Women's breasts can not only be used to feed the next generation, but also reflect the unique beauty of women's body curves. Although men also have breasts, people think that men's breasts have no practical use, and some men even have symptoms of overly large breasts, which greatly affects their appearance. In fact, men’s breasts do have certain functions. Let’s take a look at them below.

What does a normal male breast look like?
The male nipple is located in the fourth rib space. The male areola is a round, pigmented skin with a diameter of 15 to 35 mm, sometimes longitudinally oval. There are a small amount of hair and glands in the areola, including sweat glands, sebaceous glands and mammary glands. The nipple can be roughly viewed as being cylindrical or cone-shaped. Its shape varies greatly. In normal shape, the nipple is 0.5 to 1 cm higher than the areola plane. A well-shaped male breast should be elastic, of moderate size (in proportion to his body), with a moderate distance between the two breasts; the nipple should be hemisphere-shaped, the areola should be of moderate size, and its color should be consistent with the nipple; both the areola and the nipple should be colored, and the two parts should be composited together.
2. Why do men have breasts?
The reason why men all have nipples is that there are no sexual characteristics in the early stages of fetal development. Only in the later stages of fetal development does testosterone cause the fetus to have gender, and at this time, the nipples have already developed. Darwin also thought deeply about this issue when he created the theory of evolution. He speculated that in the ancestors of mammals, males and females had the same function of lactation, and that the males' breasts were also very developed at that time. Later, for some reason (such as a decrease in the number of pups in each litter), males were no longer needed to serve as "wet nurses", and the male breasts gradually degenerated.
3. The role of male breasts
1. Men’s nipples are not degenerate organs but undeveloped organs. They have blood vessels, nerves, mammary glands and other structures that enable them to play a role in lactation. If the secretion of androgen and estrogen in a man's body is out of balance, his breasts will develop. Under certain special circumstances, such as taking medications that affect hormone secretion, some men can even secrete breast milk.
2. Men's nipples also have the task of being aesthetically pleasing. From an aesthetic point of view, every symmetrical part of the human body plays a major role in beauty. A man with nipples will definitely have richer body language, instead of having his entire chest and abdomen be too flat and monotonous.
3. Nipples remind men that they need to have the same sense of responsibility as a mother has towards her children. According to Sky News, a recent study shows that men's nipples can give them more comfort when babies cry.
4. What is the reason for male breast enlargement?
Medically known as male breast hyperplasia or male breast hyperplasia, it is a clinical disease in which abnormal development of male breast tissue and abnormal proliferation of breast connective tissue is caused by an imbalance in the ratio of estrogen and androgen due to physiological or pathological factors. Including: increased estrogen levels in the body, androgen deficiency, and the effects of drugs. Male breast hyperplasia is irreversible, which means that the breast will not shrink after it grows larger, and will only get bigger if not treated for a long time.
