Ambiguous genitalia
Genitalia that are neither typically female nor typically male.
Also known as intersexual genitalia.</P> Girls (with a 46, XX chromosome constitution) can have virilized genitalia due to excess androgen action.
Conversely, the genitalia in boys (with a 46, XY chromosome constitution) can appear undermasculinized or frankly feminized because of lack of androgen action.
