Can a unicornuate uterus conceive naturally?

A unicornuate uterus is a type of uterine malformation. In this case, the uterine cavity is relatively small, so when the fetus is developing, it is difficult to bear the weight of the fetus, leading to miscarriage. Theoretically, it is possible to get pregnant with a unicornuate uterus, but the chances are relatively small. For the appearance of unicornuate uterus, patients should receive timely treatment and follow the doctor's advice.

1. Can patients with unicornuate uterus still get pregnant?

Theoretically, women with a unicornuate uterus can get pregnant, but the chances of pregnancy are not high. However, a unicornuate uterus is a developmental malformation after all, which may lead to insufficient blood supply to the fetus after pregnancy, reducing the fetal survival rate. Also, because the uterine cavity of a unicornuate uterus is smaller, as the fetus develops, the uterus will expand, and it will be unable to bear the weight of the fetus, resulting in miscarriage, premature birth, dystocia, and uterine rupture.

2. What situations may occur after a patient with unicornuate uterus becomes pregnant?

1. Normal delivery: This situation is relatively rare, but it does not mean that it is impossible. If the unicornuate uterus is well developed, pregnancy and birth are likely to be normal.

2. Repeated late miscarriage and premature birth: If the unicornuate uterus is not well developed and the uterine cavity is too narrow, the myometrium will not stretch well, making repeated late miscarriage and premature birth more likely to occur.

3. Abnormal fetal position: Abnormal fetal position is also a common situation. Because the fetus’s movement in the uterine cavity is restricted, abnormal fetal position is easy to occur, which may cause dystocia. Moreover, most of them require cesarean section, which may even threaten the life of the pregnant woman.

4. Obstetric complications: When the cervix and uterine muscle layer of patients with unicornuate uterus are poorly developed, it can cause uncoordinated contractions of the uterus, leading to the occurrence of obstetric complications, such as premature rupture of membranes, premature birth, labor arrest, postpartum hemorrhage, etc.

5. Combined pregnancy with rudimentary horn of uterus: Unicornuate uterus most often occurs together with rudimentary horn of uterus, and about 65% of patients with unicornuate uterus will have rudimentary horn of uterus. If pregnancy occurs in the rudimentary horn of the uterus, it will make the pregnancy more dangerous. When a rudimentary uterine horn ruptures naturally in the second trimester, severe abdominal pain and vaginal bleeding will occur, and massive bleeding in the abdominal cavity can cause shock and endanger life. This is also one of the main reasons for the high mortality rate of unicornuate uterus combined with rudimentary horn of uterus pregnancy.

In summary, unicornuate uterus is not uncommon. However, because the symptoms of unicornuate uterus are not obvious, some women may not discover it throughout their lives. If you experience frequent miscarriages or difficulty getting pregnant, you may wish to go to the hospital for a check-up in time and use scientific methods to solve the problem. After all, very few patients with unicornuate uterus can get pregnant naturally and give birth normally. Therefore, early detection and early treatment are the most reliable.
