What does hymen mean to women's health?

Because of China's deep-rooted concept of loyalty in ancient times, the hymen still has a great influence on modern people's view of marriage. In fact, the existence value of hymen is not only a test of women's sexual life, but also very important to the health of young women's private parts. Most unmarried women have a thin hymen on their reproductive organs. If the vulva is exposed, it can be observed that the hymen is an annular semi-closed membrane fold at the inner edge of the vaginal opening, with a hole in the center, which is half-moon-shaped, round-hole, oval and sieve-shaped. The hymen is about 2 mm thick and rich in blood vessels and nerve endings. Usually, in the first sexual life of most women, the hymen will "collapse at the touch", leading to vaginal bleeding, which is often called "seeing red" and "falling red"; Later, with the increase of sexual life times, the vaginal opening gradually became larger and the hymen disappeared. However, there are very few women born without hymen; There are also very few women who have no pores on the hymen and become "infertile women", and need to undergo "puncture" surgery, otherwise their health will be affected by the accumulation of menstrual blood. Historical experience shows that few adult women will live alone all their lives. Anthropologists have investigated some primitive tribes with fairly free marriages in New Guinea and found that beautiful, intelligent and capable women often have quite a few suitors and sexual partners. And some ugly, even deformed women, although few people pursue, will also have children. In other words, the hymen of all mature women will be broken by the sexual combination of men and women, leaving only deformed fragments. Thus, from an evolutionary point of view, the hymen seems to be an unnecessary organ; Physiologically, it is an obstacle to sexual life. Sexual life should be a pleasant experience under the emotional blending of both parties, and the existence of hymen obviously affects its formation. However, nature rarely produces useless organs, and it is an important principle of nature to use them in the middle and discard them outside. Since the hymen is not good for the man and will bring a lot of pain to the woman in sexual life, why does it still exist? Contemporary anthropologists put forward two theoretical theories, namely "protection theory" and "sexual selection theory". Anthropologists who hold this view believe that the hymen has a protective effect on women's reproductive system and even their bodies. Like the foreskin covering the male sex organs, it is a barrier and protective film to prevent the invasion of diseases and pathogens. The hymen guards the vaginal door to prevent urine from flowing into the vagina. In the primitive society of human childhood, women did not wear clothes. They put an animal skin on their lower body at most, and the open apron is easy to be invaded by dust and germs. The vaginal wall of girls is relatively thin, and the ovarian development is not yet mature. Therefore, the existence of hymen is of great significance to prevent the invasion of germs, protect the reproductive system in the body and ensure the fertility of women. But the hymen after menarche is as useless as a man's foreskin, but it becomes an obstacle to sexual life. Anthropologists who agree with the "protection theory" also believe that before 18 years old, the girl's body is not mature and the hymen is very thick, which is an early warning device to avoid premature sexual life. Modern medical data show that women who start sexual life prematurely are prone to cervicitis and even cervical cancer due to cervical infection. Hymen only plays a preventive role. Because, for men, it is difficult to overcome the tough natural protective film if they want to have sex with immature young girls and girls; For young girls, premature sexual life will bring considerable physical pain. A large number of medical investigation data show that more than two-thirds of women will "sting" and "see red" when the hymen breaks. Girls, girls in the unfortunate rape, hymen rupture, often have heartbreaking pain; Adult women, if they voluntarily have sex with the person they love, will not have obvious pain when the hymen breaks, because they are psychologically prepared. If sexual intercourse reaches its climax at this time, many women will be very happy. Anthropologists who hold the theory of sexual selection believe that the main function of hymen is to choose the strong among men and promote excellent sperm to enter the vagina for pregnancy. As we all know, in ancient times, the form of human marriage was relatively free and open, and there was no restriction on marriage age or family background, so sexual union was quite casual. The existence of hymen can prevent the old, the weak, the sick and the people with low sexual function from invading young girls. In this way, the birth of less strong offspring can be reduced or prevented, which has the evolutionary significance of choosing the strong. We know that sexual function is related to physical strength. The old, the weak, the sick and the disabled have weak physical strength and low sexual function. The existence of hymen has become a barrier to test sexual function. Those who break the "barriers" are strong and can leave their genes to future generations; Those who can't get into the "customs" are often the weak, and they have little or no chance to spread their genes. Both of the above theoretical viewpoints have some truth. However, which of these two reasons nature chooses-or whether these two reasons play a role in * * * *-needs more powerful facts to prove. Perhaps there are some deviations in nature, and this small organ of the human body is of little significance. It was only out of the need of feudal patriarchal ideology that some so-called scientific values were imposed on it-just like some people who tried to suppress and humiliate women imposed some "unwarranted" moral significance on it. It can be said that due to the reason of human concept, the hymen has caused countless tragicomedy scenes, which will make the future progress of mankind feel inexplicable.
