Learn about symptoms, diagnosis and treatment of this uncommon abnormality of the uterus that's present at birth.
A double uterus is a rare congenital abnormality. In a female fetus, the uterus starts out as two small tubes. As the fetus develops, the tubes normally join to create one larger, hollow organ — the uterus.
Sometimes, however, the tubes don't join completely. Instead, each one develops into a separate structure. A double uterus may have one opening (cervix) into one vagina, or each uterine cavity may have a cervix. In many cases, a thin wall of tissue runs down the length of the vagina, dividing it into two separate openings.
Women who have a double uterus often have successful pregnancies. But the condition can increase the risk of miscarriage or premature birth.
A double uterus often causes no symptoms. The condition may be discovered during a regular pelvic exam or during imaging tests to determine the cause of repeated miscarriages.
Women who have a double vagina along with a double uterus may initially consult a doctor for menstrual bleeding that isn't stopped by a tampon. In these situations, the woman has placed a tampon in one vagina, but blood is still escaping from the second uterus and vagina.
Seek medical advice if you have a menstrual flow despite the insertion of a tampon, or if you have severe pain with menstruation or experience repeated miscarriages.
Doctors aren't certain why some fetuses develop a double uterus and others don't. A genetic component may be a factor because this rare condition sometimes runs in families.
Many women with a double uterus have normal sex lives, pregnancies and deliveries. But sometimes a double uterus and other abnormalities of uterine development are associated with:
A double uterus may be diagnosed during a routine pelvic exam when your doctor observes a double cervix or feels an abnormally shaped uterus. To confirm the diagnosis, your doctor may recommend one or more of the following tests:
If you have a double uterus but you don't have signs or symptoms, treatment is rarely needed. Surgery to unite a double uterus is rarely done — although surgery may help you keep a pregnancy if you have a partial division within your uterus and no other medical explanation for a previous pregnancy loss.
If you have a double vagina in addition to a double uterus, you might be a candidate for an operation that would remove the wall of tissue separating the two vaginas. This can make childbirth a little easier.
You're likely to start by seeing your primary care provider. You might be referred to a doctor who specializes in conditions affecting the female reproductive tract (gynecologist) or a doctor who specializes in reproductive hormones and optimizing fertility (reproductive endocrinologist).
