Definition

By Mayo Clinic staff

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

Double uterus is rare — and sometimes not even diagnosed. The percentage of women with a double uterus is likely 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.
