What Is a Bicornuate Uterus?

If you are anything like me, you might not even know what a normal uterus looks like. It turns out that this important organ is normally pear-shaped. A healthy uterus has a gently rounded shape that is larger at the top and hollow inside. Women who have a heart shaped uterus have a uterus shaped like a heart. Instead of being a smooth, rounded dome at the top, the uterus is dented right down the middle.

This is a fairly rare condition that only affects about 7 out of 1,000 women. It is congenital, which means that if you have it you were born with it. A bicornuate uterus happens because if the fallopian tubes at the top of the uterus do not fuse together correctly.

How Can You Tell if Your Uterus Is Heart-Shaped?

I was surprised to learn that some women can spend a lifetime without knowing they have this. For many women, it is a condition that has no symptoms at all. You menstruate on time and get a normal heavy period. There is a slightly higher risk of getting endometriosis with a uterine abnormality. This is basically menstrual tissue that backs up into the fallopian tubes instead of exiting the uterus.

Signs of endometriosis include pain during periods, discomfort during bedroom activities, and abdominal pain at other times of the month. All of these symptoms are the most common sign of a bicornuate uterus. However, many women remain unaware until they try to get pregnant. A bicornuate uterus often causes repeated miscarriages and dangerously premature births. According to one study of uterine defects, a bicornuate uterus increases repeated miscarriage risks by up to 37.6 percent.

Because symptoms are not immediately noticeable for so many, it will take a doctor’s input to diagnose the condition. After repeated difficulties getting pregnant, the doctor may decide to do some tests. Imaging tests like ultrasounds may show the abnormal shape. If the ultrasound is not clear, you might need an MRI test to see if you have the condition.

Can You Get Pregnant With a Bicornuate Uterus?

If you are interested in having a child, having a heart-shaped uterus can cause some issues. However, I was happy to find that a bicornuate uterus does not affect your overall fertility. You can still get pregnant at the same rate as other women. The main concern just issues during pregnancy. Doctors will classify this type of pregnancy as high risk, and women will need extra help.

There is a four times higher risk of a baby having a birth defect. This is part of the reason why miscarriages are more likely for women with a bicornuate uterus. If the fetus is not viable, it may be miscarried. Even healthy fetuses have a higher risk of miscarriage. To lower this risk, doctors may suggest that mothers go on bed rest or get frequent checkups.

Later on in the pregnancy, there is a risk for a difficult birth. A bicornuate uterus can cause an early delivery that requires the baby to get extra care. It can also make the babysit with their feet facing downward. This is called a breech position, and it can require a Cesarean delivery.
