Hymen can prevent unclean things from entering the vagina and protect the vagina. Before puberty, due to less estrogen secreted by the ovary, thin vaginal mucosa, few wrinkles and low acidity, the resistance is poor, and the hymen has the protective effect of preventing bacteria from invading the vagina. After puberty, with the development of the ovary, the estrogen in the body increases, the vaginal resistance increases, and the hymen gradually loses its function. Hymen foramen is necessary for physiology. When a woman matures, her monthly menstrual blood is excreted through this hole. If there is no hole in the membrane, menstrual blood will be blocked by it and cannot be excreted. Medically it's called imperforate hymen. If it is not found in time, menstrual blood will accumulate in the vagina, spread upward to the uterine cavity and fallopian tube after many years, and flow into the abdominal cavity through the distal opening of fallopian tube, causing fallopian tube injury, intestinal adhesion and abdominal infection.
Generally speaking, the rupture of a woman's hymen means that she is no longer a virgin, but it is not necessarily so. Although some women's hymen is complete, it is no longer a virgin. Some women are indeed virgins, but their hymen has been broken. Because some virgins have large hymen holes, good elasticity and few blood vessels in the membrane, the man is gentle but not rude during sexual intercourse, and the hymen cannot be broken after repeated sexual intercourse; On the contrary, some virgins, due to some accidents, have their hymen broken. For example, some women are ignorant in childhood, insert small toys into the vagina, some encounter trauma, or sharp objects happen to touch the vulva, some are damaged by masturbation, washing or vaginal drug stuffing, and some are fragile and can be broken when engaged in strenuous exercise. Therefore, virgins cannot be identified only by whether the hymen is broken or not.
The role of hymen
1. Before puberty, the female reproductive organs are not fully developed, and the vaginal mucosa is fragile and low in acidity, which cannot stop the invasion of bacteria. At this time, the thicker hymen will take on this important task and protect the female reproductive system.
2. After puberty, the female reproductive organs gradually develop, and the vagina has played a role in resisting bacterial invasion, while the hymen gradually becomes fragile, thus losing this role. Therefore, for mature women, the hymen no longer has any physiological function.
