Introduction

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 cavity. This condition is called double uterus (uterus didelphys).

Each cavity in a double uterus often leads to its own cervix. Some women with a double uterus also have a duplicate or divided vagina.

Double uterus is rare — and sometimes not even diagnosed. According to one estimate, double uterus occurs in 2 percent to 4 percent of women who have normal pregnancies. The percentage may be higher in women with a history of miscarriage or premature birth.

Treatment is needed only if a double uterus causes symptoms or complications, such as pelvic pain or repeated miscarriages.
