Mayer-Rokitansky syndrome

Müllerian agenesis, also known as Mayer–Rokitansky–Küster–Hauser syndrome (MRKH) or vaginal agenesis, is a congenital malformation characterized by a failure of the Müllerian duct to develop, resulting in a missing uterus and variable degrees of vaginal hypoplasia of its upper portion. Müllerian agenesis (including absence of the uterus, cervix and/or vagina) is the cause in 15% of cases of primary amenorrhoea. [Source: Wikipedia ]
