Symptoms and causes

Symptoms

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.

When to see a doctor

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.

Causes

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.

Complications

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:

  • Infertility
  • Miscarriage
  • Premature birth
  • Kidney abnormalities
