Also known as a didelphic uterus, the double uterus is characterized as a malformation in which two uteruses and two cervixes form while a female fetus develops. In normal uterus development, the uterus begins as two tubes that join to create a larger, hollow area, which then becomes the uterus. A double uterus occurs when the tubes do not merge, but develop instead into two separate structures.

Most women who have double uteruses will never notice any symptoms of the condition, as detection is generally only obtained through imaging such as hysterosalpingogram, an ultrasound, or an MRI. Once detected, and in order to verify that the double uterus is not a bicornuate uterus, a hysteroscopy or laparoscapy may be necessary.

Fertility and conception are not at risk with a double uterus; however, pregnant women with a double uterus need to be closely monitored for any signs of preterm birth or miscarriage. As for treatment of this condition, doctors may unify the pair or remove the underdeveloped uterus during surgery.

There have been rare cases in which women have been pregnant in both uteruses and have delivered babies at different times. If both babies develop normally in their respective uteruses, then the pregnancy will likely be normal, but if one uterus and cervix is underdeveloped, then the risk of preterm labor or miscarriage is possible.

If you have any questions or concerns consult your doctor or physician.
