Cryptomenorrhea is a condition where menstruation occurs but is not visible due to an obstruction of the outflow tract. Specifically the endometrium is shed, but a congenital obstruction in the vagina or on part of the hymen retains the menstrual flow. A patient with cryptomenorrrhea will appear to have amenorrhea but will experience cyclic menstrual pain. The condition is surgically correctable.
