What is ambiguous genitalia (now known as atypical genitalia)?

Atypical genitalia, formerly known as ambiguous genitalia, is a rare disorder in which your newborn’s external genitals aren’t clearly defined. Your infant may not have the typical genitals of a male or a female. Your infant’s genitals may not have developed completely, or they may have features of both sexes.

Infants with atypical (intersex) genitals may have external genitals that don’t match their internal sex organs or genetic sex. Atypical genitalia is a difference of sexual development (DSD).
