Sex ED: Have you ever heard of a decidual cast?


Since sexual education, especially in the United States is so poor, many agree that better information and education is a necessity.
Today I learned about something called a decidual cast, and before today this was not something that I was ever taught about.

A decidual cast is a large, intact piece of tissue that is passed through the vagina in one solid piece. It happens when the thick mucus lining of the uterus, called the decidua, sheds in the near exact shape of your uterine cavity, creating a triangular “cast.”

The medical term that doctors use for this is membranous dysmenorrhea. It can happen when you’re having your period.

Doctors aren’t exactly sure what causes it. But they do believe it can be a sign of an ectopic pregnancy (a non viable life threatening pregnancy that forms outside of the uterus).

Most described experience to be excruciatingly painful accompanied with heavy bleeding, nausea, and sever cramping.
