Women, do you really understand the hymen?

　　The hymen is covering female A hollow membrane at the external vaginal opening, about 1 to 2 mm thick. Both sides of the membrane are moist mucosa. The two layers of mucosa contain connective tissue, capillaries and nerve At the end, the small hole in the middle is called the hymen hole.

　　The size of the hymen pores and the thickness of the membrane may vary from person to person. The diameter of the hymenal hole is about 1 to 1.5 cm, usually round, oval or zigzag-shaped ； Some are half-moon shaped, with the membrane hole on one side ； Some are partition-shaped holes with two small holes arranged up and down or left and right. ； Some have many scattered holes, just like the holes in a sieve.

　　The hymen prevents external unclean things from entering the vagina and protects the vagina. Before puberty, because the ovaries secrete very little estrogen, the vaginal mucosa is thin, has few wrinkles, and has low acidity, so the resistance is poor. The hymen has a protective effect in blocking bacteria from invading the vagina. ； After puberty, with the development of the ovaries, estrogen in the body increases, vaginal resistance strengthens, and the hymen gradually loses its role. The hymen hole is necessary for physiology. After a woman matures, monthly menstrual blood is discharged from the body through this small hole. If there is no small hole in the membrane, the monthly menstrual blood will be blocked by it and cannot be discharged from the body. Medically, it is called hymenal atresia. If not discovered in time, menstrual blood accumulates in the vagina and can expand upward over time. Uterus The lumen and fallopian tube flow into the abdominal cavity through the distal opening of the fallopian tube, causing damage to the fallopian tube, intestinal adhesion, and abdominal infection.

　　***Postpartum and postpartum hymen

　　Virgin's first sexual intercourse, male When a penis is inserted into a woman's vagina, the hymen is often broken and cracks are formed. The cracks in the hymen are often multiple and extend radially from the center to the surroundings. Since the male penis enters in a generally downward and inward direction, the cracks are deep on both sides of the vaginal opening and can reach the base, which is called a complete rupture. Sometimes due to the man's excessive force during intercourse, the nearby vaginal wall can also be lacerated. Women who have given birth, due to fetus Vaginal delivery further damages the hymen, leaving it incomplete, sometimes leaving only a few remaining protrusions, called hymen marks. If the child was delivered by caesarean section, baby It is delivered from the incision in the lower abdomen and does not pass through the vagina, so the hymen still maintains its post-marital shape.

　　The relationship between hymen and virginity

　　Generally speaking, the rupture of a woman's hymen means that she is no longer a virgin, but this is not always the case. Although some women's hymen is intact, they are no longer virgins. Some women are indeed real virgins, but their hymen has been ruptured. Because the hymen of some virgins has large holes, good elasticity, and few blood vessels in the membrane, and the man is more gentle and not rough during intercourse, the hymen may not rupture after multiple intercourses. ； On the contrary, some virgins have their hymens ruptured due to some accidents. For example, some women are ignorant in childhood and insert small toys into the vagina. Some women encounter trauma or sharp objects happen to touch the vulva. Some are damaged due to masturbation, washing or vaginal plugs. In some cases, the hymens are already very fragile and can be ruptured when engaging in strenuous exercise. Therefore, you cannot determine whether you are a virgin simply by whether your hymen is broken.
