What are the hazards of congenital absence of vagina to pregnancy?

You should know that in our daily life, many female friends are troubled by congenital absence of vagina. This symptom brings great harm and pain to female friends. So, can "congenital absence of vagina" get married and have children? Let us learn about its related content together:

"Shi Nu", commonly known as "Shi Xin Zi" among the people, means that they are born without vagina, but have general female sexual characteristics, sexual desire and normal female psychological state. From an anatomical point of view, "Shi Nu" is mainly due to the deformity and blockage of the menstrual passage, and they do not have menstruation or the menstruation cannot flow out.

There are two types of "stone women": "external stone" and "internal stone". "External stone" is also called "false stone". It means that the penis cannot be inserted into the vagina after marriage due to the thickening or occlusion of the hymen. This kind of "external stone woman" can be corrected by hymenotomy, and she can have a normal sex life after the operation. "Internal stone woman" refers to congenital absence of vagina. This is due to the fact that the Mullerian ducts that develop into the uterus and vagina during the embryonic period have not been cavified.

"Stone women" have no vagina, and are usually discovered only after they have no menstruation after puberty or cannot have sexual intercourse on their wedding night. "Stone women" can be discovered in time during premarital physical examinations. Through correction and "reconstruction" of the vagina, they can have a happy sex life in the future. Some women, although without a vagina, have a normally developed uterus. After the menarche, the menstrual blood cannot flow out every month, so it accumulates in the uterine cavity. When the uterine cavity is filled, the menstrual blood flows into the abdominal cavity through the opening of the fallopian tube. Due to the stimulation of menstrual blood in the uterus, the uterus will have paroxysmal spasms and contractions, and periodic abdominal pain will occur. If the ovaries of people without vaginas can secrete a certain amount of female hormones, their breasts will develop, pubic hair will grow, and they can still have female secondary sexual characteristics.

Some people are born without vagina, and some have no uterus or a juvenile uterus. Without a uterus, there is no endometrium, and menstruation cannot occur. In other words, the uterus of an unmarried young woman is small and long like that of a young girl, and the endometrium is very thin, so menstruation cannot occur. Some "barren women" have a vague vaginal appearance, but there is a diaphragm blocking the vagina, or the vagina is partially closed. Even if there is a uterus and endometrium, menstruation cannot flow out, let alone sexual intercourse.

Hymen occlusion is also a type of "barren woman". Under normal circumstances, the hymen grows outside the vagina. It is a thin membrane with an opening in the middle, from which menstrual blood or vaginal secretions flow out. If the development is abnormal, the hymen has no opening, which is called hymen occlusion or imperforate hymen. In this type of women, the development of the uterus and vagina is mostly normal, but because of the hymen occlusion, menstrual blood cannot flow out during menstruation. At first, menstrual blood accumulates in the vagina, and then in the uterus and fallopian tubes. Its symptoms are the same as those caused by menstrual blood retention without a vagina, and there are also abdominal pain and lumps. During a gynecological examination, you can see that the hymen bulges outward and is purple, which is caused by blood accumulation.

Can "barren women" get married and enjoy married life? The answer is yes. "Barren women" can be corrected and get married. Women without vagina but with normal uterine development should undergo surgical correction at the age of menarche to prevent menstrual blood retention from inducing endometriosis. If the uterus is dysplastic or lacking, Chinese medicine and estrogen can be used for treatment. For example, a small dose of 0.5-1 mg of ethinyl stilbestrol can be taken orally once a day for 3-4 menstrual cycles; or thyroxine tablets and vitamin E can be taken at the same time to "stimulate" uterine development. Some scholars advocate that a contraceptive ring can be placed in the uterus to use the regular stimulation of the ring to promote the growth of the uterus. Under the guidance and monitoring of a doctor, it can be tried for 2-3 months.

For congenitally vaginal agenesis, compression and dilation and vaginoplasty can be used for correction. The so-called compression and dilation method is to apply mechanical pressure to the shallow pit equivalent to the external opening of the vagina with a smooth blunt wooden round stick, twice a day, 20 minutes each time, and after about 3 months, the shallow pit can reach a depth of 7-8 cm. The vagina expanded by compression can basically meet the needs of sexual life.
