In this review, we describe normal development of fetal genitalia throughout gestation as well as the identification of normal male and female genitalia on ultrasound. We use abnormal and ambiguous genitalia as illustrative tools to assist with the identification of normal genitalia and recognition of some of the most common abnormalities in external genitalia development.
Keywords: ambiguous genitalia; disorder of sexual development; fetal diagnosis; prenatal diagnosis; prenatal ultrasound.
