The hymen is a mysterious structure due to the privacy of women. Many people are curious about it, and they become a symbol of chastity in the eyes of many men! In fact, the hymen of "broken" is normal!
The so called hymen refers to a circular mucous membrane at the female vaginal mouth. It is in a thin film shape. The vaginal opening is located at the back of the vestibule behind the outer mouth of the urethra. Its school name "vaginal petals". The thickness of the hymen is about 12mm. It has abundant microvascular, nerve endings and connective tissues, and has a hole in the middle, about 11.5 cm in diameter. Essence
So the hymen of "broken" is normal! Because it is perforated in itself, assuming it is fully enclosed (of course, some people are born without hymen, showing a lock up state, and need surgery). So where did the blood flow from the menstrual period?
The distance and thickness of the hymen to the vaginal port will slowly move with age. The hymen of the baby girl will be relatively thicker, and the vagina of the baby girl is relatively narrow. Therefore, the early hymen has a certain role in protecting the cervix and uterus. As you get older, the hymen will slowly become thinner and more and more leaning. Finally, you will come to the position of the vaginal opening. The hymen position of mature women is generally within 03cm of the vaginal port.
For adult women, the hymen does not have any known biological functions, and its shape varies from person to person. Its texture is similar to tongue lace, that is, the tissue between the tongue and the bottom of the mouth when the tongue is raised and raised the tongue.
According to the shape of the hymen hole, it can be divided into circular, oval, ring shaped, sieved, crescent like, perforated, etc. There are more than 30 shapes. The form of hymen is different, there are large and small, one hole, two holes, and some even pervasive.
Generally speaking, women will break and bleed during their first sexual life, but still about 30 % of women will not bleed or even have a small amount of bleeding at the first time. Shape. This has something to do with the form of hymen. Like an umbrella like hymen, its elasticity will be better, allowing "Tintin" to pass without causing rupture. In addition, the hymen will not only break the first time "Papa", it is likely that it will also be cleaned (such as high jumping, horse riding, martial arts, etc.). rupture.
Therefore, male friends, please do not use "falling red" to identify women&39;s chastity! There are hymen are not necessarily virgins, and there is no hymen and not necessarily virgin. The two are not sufficient nor necessary. If they just use hymen to determine whether a girl is chastity, it is too outrageous!
