Penile agenesis is a birth defect in humans occurring about once in 5–6 million male births in which a male child is born without a penis.A partner condition is testicular or gonadal agenesis. This is when a male child is born without gonads and consequently develops no testes.Penile agenesis occurs often as a consequence of Testicular agenesis but the reverse is never the case.Most patients in both cases have no known family history and usually have an otherwise normal male anatomy.
