Youtube star Cassandra Bankson recently surprised her followers by revealing that she was born with two vaginas. The makeup guru, who has more than 750,000 followers to date, only learned of her condition recently.

The condition is known as uterus didelphys, and there are fewer than 100 known cases around the world. The male equivalent, which we introduced you to recently, is even rarer. In typical embryonic development, a female fetus will have two vaginal tubes which later fuse together. With uterus didelphys, this fusion does not occur, and the fetus continues to develop with two uteruses, two cervixes, and often two vaginas. It's not known why this occurs. The condition is often asymptomatic, and sufferers may not realize they have it at all.
