ambiguous genitalia: a birth defect of the sex organs in which, from their embryonically undifferentiated state, they have failed to become fully differentiated as either male or female, but are unfinished. At birth the baby's sex cannot be declared on the basis of visual inspection. Diagnostically, the term is hermaphroditism or intersexuality. Embryologically, it is not possible to develop a complete penis and scrotum together with a complete vagina and vulva.
