What role does the man's nipple play? Why do men grow nipples? Many people think that male nipples are just to distinguish between positive and negative.
The difference between men and women is the difference between chromosomes XX and XY. In fact, regardless of men and women, his factory settings are all girls, X stands for nipples of men and women, and Y distinguishes the lower body of men and women. Not only that, nipples actually grow earlier than Tintin. The nipple begins to grow in the 3-4 weeks of embryonic development, and stops developing in the 6-7 weeks when the Y chromosome begins to release androgen.
Back to the topic, I summarize the function of man's nipple in the article.
1. Can help. The compression position of cardiopulmonary resuscitation is generally in the middle of two nipples. If one day the nipple disappears, do you want to measure it with a ruler? With nipples, you can quickly locate rescue and may save lives.
2. You can have fun. Men's nipples are all sensitive. Stimulating a man's nipples can give him a certain pleasure, promote the relationship between husband and wife, and have some fun in carrying on the family line.
You can take a baby. Although a man's nipple is an ornament, it can also produce milk through certain drug stimulation. Dad can sleep when mom is not at home. So that's what dad means?
However, it is very interesting that some men have "sad nipple syndrome" in their nipples. When touching nipples, men will feel sad and sad, and some even want to commit suicide. If this happens, you must seek medical attention in time.
Moreover, men's nipples are actually more fragile than women's. They don't have a bra to protect them, so they can easily wear out their skin if they are not careful.
In addition, men do get breast cancer, and one in every100000 men will get breast cancer. This is more common in older men.
Therefore, boys must protect themselves when they go out. If you feel uncomfortable, you must see a doctor in time!
