A double uterus is a rare uterine malformation in women. Women with a double uterus can still have a normal pregnancy and birth, but they are more likely to have serious pregnancy complications, such as premature birth, stillbirth, difficulty giving birth, miscarriage, or even miscarriage. even infertile.1. What is a double uterus?
The uterus, also known as the womb, is a female genitalia and a hollow, pear-shaped internal organ. Normally, each woman will have one uterus, two fallopian tubes, two ovaries, and one vagina. However, women with birth defects can have two uteruses (double uterus). This is a very rare congenital abnormality, only one in thousands or even millions of people. A double uterus is typical for uterine abnormalities, including a round uterus, uterine malformation, or a bicornuate uterus.A double uterus will have two separate uterine chambers, each of which can lead to the cervix and vagina. That is, women with a double uterus will have two uteruses, two separate vaginas, and two fallopian tubes.
Pregnant women with a double uterus cause the arterial branches to nourish the fetus will be scattered, in addition, the uterine lumen is narrow and the uterus has difficulty in expanding, which will lead to miscarriage. pregnancy, stillbirth, fetal growth retardation, fetal malnourishment or premature birth.
2. Causes of a double uterus
A double uterus is a malformation of the uterus that usually occurs while the fetus is developing in the womb. During embryonic development, the fetus' uterus will be formed by merging two parallel ducts, thereby forming a hollow organ called the uterus. If this merging process does not face any difficulties or obstacles, it will form a completely normal and healthy uterus. On the contrary, if abnormalities occur during fusion, it can lead to bicornuate or double uterus.The cause of this incomplete merger is currently unknown. However, according to experts, one of the main causes of this rare uterine abnormality is genetic factors.
Women with a double uterus often have one cervix, one vagina, or each uterus has a separate cervix. In some cases, a double uterus will form a septum along the vagina and divide the vagina into two separate passages.
Although this is a rare birth defect of the uterus, it makes it less difficult for women to get pregnant. This means that women with a double uterus can still get pregnant and give birth as normal. However, the abnormal condition can cause some complications such as a high risk of miscarriage, slow fetal growth, premature birth or even infertility.

3. Effect of twin uterus and risk of miscarriage
If there are no medical or obstetric complications, this abnormality in the uterus will not cause any symptoms, so it will be difficult for women to know if they have a double uterus. or not. To recognize this condition, doctors need to perform pelvic exams and go through imaging tests periodically.Most women with a double uterus still comfortably enjoy the "marital sex" life like other women. However, for women with a double uterus during pregnancy, there may be the following risks:
Difficult birth: During pregnancy, the uterus containing the fetus grows, but the uterus remains. just a little bigger than usual. Because the position of the non-pregnant uterus is low, during labor it will make it difficult for the fetus to pass out, causing difficulty in delivery. That's also why the rate of cesarean section is higher than usual in people with a double uterus. In fact, there are women who have a twin uterus who are able to give birth vaginally if the fetus is small and the remaining uterus does not obstruct the exit of the fetus. Low birth weight: Usually, women with one uterus will have two uterine arteries to supply blood. However, people with a double uterus have only one uterine artery that supplies blood to each uterus. As a result, the blood supply to the fetus will be reduced, increasing the risk of having a low birth weight baby. Premature birth: because the uterus containing the fetus in a person with a double uterus is more limited than that of a person with a single uterus, this can easily lead to premature birth. Miscarriage: Women with a double uterus rarely have both uteruses fully developed. When the fetus implanted in the uterus is not complete, the ability to keep the fetus will be very low. In addition, those carrying this abnormal uterus will have a very narrow uterine cavity, when the pregnancy is too large, the uterus will have a self-rejection mechanism. These factors are the main causes leading to the risk of multiple miscarriages or premature birth.

4. Double uterus treatment
If a double uterus doesn't cause any complications, you won't need surgery. In case, the test results show that there are two double uteruses along with two vaginas, the doctor may prescribe surgery to remove the septum that divides the vagina into two, to make it easier for the pregnant woman. more in childbirth.Another effective method to treat a double uterus is removal of the uterus that is not working well. However, this method should be carefully considered before performing because it is associated with endocrine problems in women and can affect the blood supply to the uterus. In addition, women who have a double uterus and are in pregnancy must pay special attention to pregnancy health because there is a high risk of risks such as abnormal fetal position, delayed fetal growth. development due to narrowing of the uterus, premature birth or even stillbirth. Ideally, you should go for regular check-ups so that your doctor can monitor you regularly and give you useful advice.
