In a very rare condition called uterus didelphys, some women are born with not one, but two uteruses. This happens as the reproductive system is forming in the fetus; the uterus starts out as two tubes that join together to form one organ. When the tubes fail to fuse, each turns into its own uterus. Sometimes the vagina is duplicated, too, creating a forked path to each uterus. In many cases, the condition is symptom-free, though unusual menstrual bleeding or fertility troubles can be hints that something isn't right. |
