It is rare to be unable at birth to differentiate a male from a female newborn because of the presence of ambiguous genitalia, but abnormalities of the external genitalia that need further investigation may occur in about 1 in 4000 births [1]. Antenatal ultrasound scanning has improved our ability to predict these conditions.
