Imperforate Hymen

What is imperforate hymen?

A half moon of thin membrane normally surrounds the opening of a young girl's vagina. In the case of an imperforate hymen, a membrane extends all the way across the area of the hymen, blocking the vaginal opening. It is easily corrected through a minor surgery.

An imperforate hymen may be detected in a newborn, as there may be a bulge in the hymenal membrane from normal mucus in the vagina that cannot drain. The imperforate hymen may not be diagnosed until childhood or at the time of a girl's first period.
