The evaluation of the newborn infant with ambiguous genitalia is one of the most complicated challenges of medicine. Possibly no other field requires a broader application of both theoretical and practical knowledge, and certainly few decisions have greater social impact on the future of the patient. The aims of this article are threefold: to present a short summary of normal sexual differentiation; to provide a simple classification of those disorders that most frequently present as ambiguity of the external genitalia in the newborn; and to summarize the differential diagnosis, evaluation, and gender assignment in infants with ambiguous genitalia.
