Definition
By Mayo Clinic staffAmbiguous genitalia is a rare condition in which an infant's external genitals don't appear to be clearly either male or female. In ambiguous genitalia, a baby's genitals may not be well formed or the baby may have characteristics of both sexes. In a baby with ambiguous genitalia, the external sex organs may not match the internal sex organs.
Ambiguous genitalia isn't a disease. Instead, it is a sign of a condition that affects sexual development.
Ambiguous genitalia is usually obvious at or shortly after birth. Ambiguous genitalia can be very distressing for families. Your medical team will determine the cause of ambiguous genitalia and provide information and counseling that can help guide decisions about the baby's gender.
