The “stone woman”, in the people has been a “taboo” word. In the eyes of people, “stone woman” is not only not really a woman, but also often seen as a symbol of bad luck, inauspicious. So what is the stone woman, stone woman and how to form it? The so-called “stone girl” actually refers to a woman who was born without a vagina or congenital vaginal occlusion. It is not uncommon for women to be born with a vagina, and the incidence is as high as 1 in 4,500, which is much higher than many congenital diseases. The formation of stone women is generally associated with these two causes: 1. Early in pregnancy, the pregnant woman is infected with a virus, exposed to radiation, certain toxic chemicals or drugs that affect the development of the fetus, causing abnormalities in the development of the fetal reproductive organs, resulting in congenital absence of the vagina or vaginal dysplasia. 2, early in pregnancy, the embryo development process by some intrinsic or external factors interference resulting in chromosomal mutations, fetal development malformations, resulting in congenital anovaginal and uterine or vaginal dysplasia resulting in stone girl. Did you know that there is a difference between true and false stone women? True stone (endolith): True stone women are congenitally absent or atretic vaginas, which refers to dysplasia or absence of the vagina or vagina and uterus in the reproductive organs. This type of vaginal absence is most often found in women who have no menstrual periods after puberty or who are unable to have normal sexual intercourse. In some women, the vagina is absent but the uterus is normally developed. After the first menstrual period, menstrual blood will come every month, but it cannot flow out and accumulates in the uterine cavity. When the uterine cavity is filled, the menstrual blood flows into the abdominal cavity along the opening of the fallopian tube. The stimulation of menstrual blood in the uterus causes paroxysmal spasmodic contractions of the uterus and periodic abdominal pain. In vaginal nulliparous women, if the ovaries produce a certain amount of female hormones, they can stimulate breast development and pubic hair growth and still have female secondary sexual characteristics. However, most congenital nulliparous women have no uterus or an infantile uterus. If a woman does not have a uterus, of course, she will not have an endometrium and will not be able to produce menstruation, or if a young unmarried woman has a small and long uterus like a young girl, and a very thin endometrium, she will not produce menstruation. Pseudoliths (ectoliths): Pseudoliths, on the other hand, are hymenal atresia (or hypertrophy) or vaginal diaphragm, meaning that the vagina and other reproductive organs are well developed and the penis cannot enter due to abnormalities in the vagina or hymen only. In this type of women, although there is a vaginal shape vaguely, there is a diaphragm blocking the vagina or the vagina is partially atretic and even though there is a uterus and endometrium, menstruation does not flow, much less sexual intercourse. Under normal circumstances, the hymen grows at the outer opening of the vagina and is a membrane with an opening in the middle from which menstrual blood or vaginal secretions flow. If the hymen is abnormally developed and there is no opening, it is also known as hymenal atresia or an imperforate hymen. In this type of women, the development of the uterus and vagina is mostly normal, but because of the hymenal atresia, menstrual blood does not flow out during menstruation, and at first it accumulates in the vagina, and then also in the uterus and fallopian tubes. It presents with the same symptoms as menstrual blood retention caused by absence of vagina, as well as abdominal pain and masses. During a gynecological examination, the hymen may be seen to bulge outward in a translucent purple color, which is caused by the accumulation of blood. From the anatomical point of view, “stone girl” is mainly a deformity of the menstrual channel, blockage, no menstruation or menstrual flow, so when there is no menstruation after puberty, accompanied by after not accompanied by periodic abdominal pain, women should go to the hospital as soon as possible, through gynecological examination can be detected and treated early. Although some “stone girls” are born without a vagina, it is not a terminal disease and they do not have to feel inferior because of this defect. If the uterus is normally developed, there is a chance of pregnancy after the surgery; if the uterus is dysplastic or missing, a normal sexual life can be restored by doing the surgery, just not pregnancy; and in the case of pseudolithotomy, a hymenotomy is all that is needed.
