Vaginal folds

Vaginal folds

I believe that many women will find wrinkles at their vaginal opening. This is normal because the vaginal wall is generally like this, and the vaginal opening is located on the vaginal wall. The vagina is quite important for women. Whether it is the vaginal opening or the vaginal wall, women must take good care of it to avoid some gynecological inflammation. Here I will introduce you to some relevant knowledge about the vagina!

1. Introduction to the vaginal wall

The vagina is also the passage for menstrual discharge. Vaginal occlusion, such as imperforate hymen, vaginal diaphragm, and traumatic vaginal atresia. It will prevent menstrual discharge and accumulate in the uterine cavity, fallopian tubes and even the abdominal cavity, thus leading to abdominal pain, endometriosis, infertility and other intractable gynecological diseases. Therefore, if menarche has not yet occurred 2-3 years after puberty breast development, you should go to the gynecology department for a check-up so that possible vaginal atresia can be diagnosed and treated early to prevent other secondary diseases.

The vagina is also a window for gynecological examination. Although the cervix is ​​only the size of an olive, it is one of the most common sites for cancer in women. Cervical cancer and its precancerous lesions can be detected early through the vaginal window for early treatment. A transvaginal digital examination can also reveal the presence of ovarian tumors and other lesions.

2. The role of the vagina

The vagina plays an important role in the reproductive process. The vagina is the place where semen is stored during sexual intercourse. The semen pool formed on the posterior side of the vagina is just opposite to the cervical opening. Sperm can quickly enter the cervical canal at the shortest distance, pass through the uterine cavity and fallopian tube, and look for the eggs discharged that month. If it is the woman's ovulation period and there are no other reproductive obstacles, fertilization will occur and new life will be born. After 40 weeks of gestation, the new life is delivered.

3. Characteristics of the vagina

The vagina has great stretchability. The vaginal walls of women of childbearing age have many vertical and horizontal wrinkles. During pregnancy, the wrinkles become deeper and larger. In addition, the vaginal walls themselves are elastic, so they can expand easily. In addition, the seven bones that make up the fetal head have not yet closed, and there are wide gaps between them. When the fetus is pushed downward by the contraction of the uterus and the pressure of the mother's exhalation, the bones gradually move closer together and even overlap, thereby reducing the diameter of the head to facilitate passage through the vagina. This vaginal dilation and fetal head reduction requires a certain process, usually about 1-2 hours. If the time is too short, it may cause severe vaginal tearing and intracranial hemorrhage in the fetus, and even be life-threatening. For first-time mothers over 35 years old, the vaginal wall has few and shallow wrinkles and poor elasticity, which often makes it difficult for the fetus to pass through, thus causing dystocia.
