Can developmental abnormalities of the uterus cause female infertility?

Can developmental abnormalities of the uterus cause female infertility?

The uterus is one of the important organs of pregnancy. So, will women with abnormal uterine development be able to give birth? This depends on the type and degree of deformity and cannot be generalized.

Because there are many types of malformations caused by abnormal uterine development, they can generally be divided into two categories: atretic and non-atretic. Due to the closed outlet of the atretic uterine malformation, menstrual blood cannot flow out during menstruation. As a result, periodic lower abdominal pain will occur after sexual development. This condition will lead to infertility without treatment. However, it can be detected in time before marriage and can be diagnosed and treated in time. Of course, some of them are incurable.

There are many types of non-atretic uterine malformations, such as:

①Delphied uterus. The two uteruses enter their respective vaginas at the same time, separated by connective tissue;

② Bicornuate and bicervical uterus. Two uteruses enter the same vagina, and the two cervixes are visible;

③Bicornuate unicervical uterus. The two lower parts of the uterus are fused, and one cervix extends into the vagina;

④Unicornuate and monocervical uterus. In fact, it is equal to half of the uterus, and there is no fallopian tube and uterine horn on the other side;

⑤ Rudimentary horn uterus. Half of the uterus is well developed. Although the other half of the uterus has a uterine cavity, it does not have a uterine mouth, so it is not connected with the developed half of the uterus;

⑥ Incomplete uterine separation. 1 uterus, part of the uterine cavity is divided into two by the diaphragm;

⑦The uterus is divided by the diaphragm. The uterine cavity is completely divided into two parts by the diaphragm;

⑧Arcuated uterus. The fundus of the uterus is arched.

Some include uterine dysplasia in the scope of uterine malformations, which mainly refers to the underdevelopment of the uterus.

According to the development of the uterus, it can be divided into: ① Primitive uterus. The uterus is very small, only 1 to 3 cm long, and has no uterine cavity, so there is no menstruation; ② Solid uterus. The appearance of this kind of uterus is similar to that of a normal uterus, but it is slightly smaller than normal. There is no uterine cavity and endometrium inside. It is a solid uterus, so there is no menstruation. The above two types also belong to atretic uterus; ③ immature uterus. That is, general uterine dysplasia means that the structure and shape of the uterus are normal, but small, and the cervix is ​​relatively long.

Among the many malformed uteruses, although the twin uterus can be pregnant, the pregnant uterus develops and increases, while the unpregnant uterus increases slightly, resulting in an imbalance and prone to torsion of the pregnant uterus. double hornsUterus and unicornuate uterus are prone to abnormal fetal position in the third trimester of pregnancy, with breech presentation being the most common. If the fertilized egg is implanted in the rudimentary horn of the uterus, it will rupture and cause internal bleeding in the 16th to 20th week of pregnancy because there is no way out. If the fertilized egg is implanted on the underdeveloped uterine wall or mediastinum, it will not mature and can cause miscarriage, habitual abortion and premature birth. Although patients with immature uterus are often treated as infertility, most of them can still become pregnant after treatment.

Most uterine malformations have no typical symptoms, so they are often discovered during hysterosalpingography. Treatment should be determined based on the specific situation. Uterine dysplasia can be treated with estrogen; foreign body stimulation, such as placing a small intrauterine device in the uterine cavity for 2 to 3 months, can also promote uterine enlargement. Surgical treatment is required for uterus with rudimentary horns, uterus doelphi and septate uterus. About 70% of patients with double uterine malformation can become pregnant after surgery, and most of the pregnancy processes are normal.

After pregnancy with an abnormal uterus, miscarriage and premature birth should be prevented. During labor, you should observe closely, choose the mode of delivery, and pay attention to prevent placenta retention, bleeding and infection after delivery. Most of the time, you can have a happy baby.
