Individuals with 5-ARD are born with male gonads, including testicles and Wolffian structures.
The development of the genital tubercle tissue (which by week 9 of a fetus' gestation becomes either a clitoris or a penis) tends towards a size qualifying it as an ambiguous macroclitoris/micropenis (large clitoris/small penis), and the urethra may attach to the phallus.
