Virginity is not a gift that a woman “gives”, but rather the integrity of a woman’s self-respect and body. Only when a woman truly understands and respects her body will the specter of a hymen not become a shackle on the soul. Here’s a look at the miraculous changes in a woman’s hymen over the course of her life. A. What is the hymen for? Our bodies, each part of which is a careful masterpiece of God, are always constructed with unparalleled precision and ingenuity. So, what is the function of the hymen? Why is there no “virginity hymen”? Is it really God’s way of demanding chastity from women? After years of research, anthropologists have come up with two theories: the theory of protection: the vaginal walls of young girls are thin, the ovaries are not yet mature, and the hymen plays a very important role in blocking the invasion of germs, protecting the internal reproductive system, and maintaining fertility. Sexual selection theory: The function of the hymen is to select the strongest of the males so that good sperm can enter the vagina for conception, which has important evolutionary significance. In the ancient flood age, human sexual union was highly discretionary, and the presence of a hymen prevented the encroachment of women by men with low sexual function. There is a correlation between sexual function and physical strength, and those who are physically weak usually have lower sexual function. The hymen forms an inspection barrier, and those who break the “barrier” enter, so that they can leave their genes to future generations. Second, the hymen of the three stages of change 1, girlhood: hymen covered in the vagina near the external mouth, about 1-2 mm thick, in the middle of a small hole, called “hymen hole”, about 1 cm in diameter, usually round, oval or serrated; some are half-moon shape, membrane hole on one side; some for the septum hole, there are two small holes for up and down or left and right side by side; some have many scattered small holes, like a sieve. During menstruation, menstrual blood is expelled through these pores. If there are no pores on the membrane, the monthly menstrual blood is blocked and accumulates in the vagina, expanding upward into the uterine cavity and fallopian tubes, and even into the abdominal cavity, resulting in broken fallopian tubes, intestinal adhesions, and abdominal infections, which is medically called “hymenal atresia” and requires gynecological surgery. Before puberty, the hymen is a barrier to bacterial invasion of the vagina due to low estrogen secretion from the ovaries, thin vaginal mucosa, few wrinkled walls, low acidity and weak resistance. After puberty, with the development of ovaries, estrogen increases in the body, vaginal resistance is strengthened, and the hymen loses its role. 2, the first night The first time you have sex, the hymen is broken and a fissure is formed, and bleeding is caused. As hymens vary in shape, the degree of rupture can vary greatly. The septum-shaped hymen with two holes bleeds more and is accompanied by more intense pain. The labial hymen bleeds very little and is almost painless. The thicker and more flexible umbrella hymen may not rupture at all! According to a survey of American gynecologists, about 30% of women do not bleed during first intercourse. This 30% includes the more elastic umbrella hymen, which may rupture only after multiple sexual encounters or after one of the more frantic sexual excursions, but may not bleed. It also includes the extremely rupture-prone porous sieve-shaped hymen, which may have ruptured for various reasons before the first sexual intercourse. 3. After childbirth The hymen is further broken as the fetus is delivered vaginally. Sometimes only a few remnant protrusions called hymenal scars are left. This change does not occur with a cesarean delivery. The hymen can be repaired through surgery. Hymenal repair is a very simple surgical procedure: using the remaining hymen, surgical sutures are applied to restore it as close as possible to its pre-rupture state. Ruptures caused by external impact, sports tears or a few sexual encounters are easily repaired. However, it is more difficult to recover after many sexual intercourse.
