What are the dangers of congenital absence of uterus?

Congenital uterine malformation is the most common genital malformation and has great clinical significance. During the evolution of the bilateral mesonephric ducts, affected and disturbed by certain factors, they may stop developing at different stages of evolution and form various uterine malformations. So, what are the dangers of congenital absence of uterus?

In congenital absence of uterus, the paramesonephric ducts on both sides extend horizontally to the midline and merge. If they stop developing before reaching the midline, this is the so-called corner uterus and vagina. If they fail to "cavitate", no uterus will be formed. Congenital absence of uterus is often combined with congenital absence of vagina, but there may be normal fallopian tubes and ovaries. During rectal examination, the uterus cannot be touched at the position equivalent to the cervix and uterine body, but only the peritoneal folds can be felt.

Infant uterus, the uterus stops developing in late pregnancy or any period from birth to puberty, and various degrees of uterine hypoplasia may occur. The cervix of this type of uterus is relatively long, mostly cone-shaped, and has a small external opening. The uterus is smaller than normal and often extremely anteverted or retroverted. Those with anteverted uterus often have underdeveloped anterior uterine wall, while those with retroverted uterus often have underdeveloped posterior uterine wall. Infant uterus can cause dysmenorrhea, oligomenorrhea, amenorrhea, or infertility.

In the medical field, there is a disease that makes people distinguish their true gender, that is hermaphroditism. Hermaphroditism refers to an individual's sexual organs showing the performance of both males and females. The cause of hermaphroditism is the abnormal development of sexual organs during the embryonic period caused by abnormal sex chromosomes and abnormal androgen secretion.

Not all patients with hermaphroditism are infertile. For female patients with pseudohermaphroditism who are "qualified" as female after surgery, the fertility rate is closely related to the treatment time. If the uterus is well developed and treatment is received before the age of 2, the fertility rate is high. The longer it is delayed, the lower the fertility rate, and it will drop to 1% after the age of 18. Some patients with true hermaphroditism have well-developed uterus, ovaries and testicles, and the fertility rate is high without treatment, and they can have children as both husband and wife.
