Hematocolpos

Hematocolpos is a medical condition in which the vagina fills with menstrual blood. It is often caused by the combination of menstruation with an imperforate hymen.

A related disorder is hematometra, where the uterus fills with (menstrual) blood. This can be caused by a congenital stenosis of the cervix, or by a complication of a surgical treatment, with stenosis of the cervix.
