Persistence of the urogenital membrane has been recently encountered in two young adult females who otherwise had normal external and internal genital development. The anomaly interfered with normal coital function, although not precluding a pregnancy. Since the entity can cause distressing clinical problems in the adult, there is need for early and periodic gynecological screening, beginning with the careful inspection of the external genitalia of all newborn infants.
