It turns out that women's membrane has this wonderful use

This layer of membrane of women has always been a focus of attention from ancient times to the present, and many farces have been staged on TV, in movies, and in real life. From the perspective of gynecology, the hymen is a natural protective barrier for the female reproductive system, preventing bacterial invasion and ensuring fertility.

This membrane appears, develops and forms when the fetus is 3-4 months old. By puberty, the shape and thickness of the hymen are completely perfect and vary from person to person. Most of them are wheel-shaped, ring-shaped, crescent-shaped, sieve-shaped, etc. A thin film of tissue that surrounds the vaginal opening and the vestibule of the vagina, about 0.5 cm wide. The circular hole in the middle can be divided into more than 30 shapes, including circular, oval, ring-shaped, sieve-shaped, umbrella-shaped, lobed, star-shaped, etc. The most common shapes of hymen holes are circular and oval.

1. This membrane is unique to human females, except for "stone women"

This membrane is not present in all female mammals, it is unique to human females. In the world, there are also a small number of women who are born with vaginal absence or vaginal atresia, which means their genitals are underdeveloped or absent, and they are called "stone women".

If menstruation is unable to occur, menstrual blood will accumulate in the vagina for a long time, causing it to flow up into the uterus, or even the fallopian tubes, abdominal cavity, etc., causing infection and abdominal pain, which is a serious situation.

2. Protect the female reproductive system

This membrane is a barrier that protects the body from the invasion of pathogens and can effectively prevent urine from penetrating. Especially in ancient times, when humans did not care about covering their bodies with clothes, this layer of membrane could prevent bacterial invasion and play a better protective role.

Nowadays, it is more reflected in the sanitary protection of the uterine cavity during the development of the ovaries, as well as the protection of the internal reproductive system and female fertility, so women should take care of themselves.

3. The barrier of “survival of the fittest”

"Survival of the fittest" further reflects the importance of this membrane, as only high-quality sperm can enter the body for fertilization.

I still remember a male friend once confided in me: "My girlfriend is pregnant. When we first got together, since we live in the countryside, the neighbors thought she had never had a boyfriend and that she was at a disadvantage because of me. On the first night we were together, I found out the truth and I was very angry. I was the one who was at a disadvantage, okay?" This may be the heart knot of Chinese men.
