Figure 2. Different degrees of virilization according to the scale developed by Prader (15)Stage I: clitoromegaly without labial fusionStage II: clitoromegaly and posterior labial fusionStage III: greater degree of clitoromegaly, single perineal urogenital orifice, and almost complete labial fusionStage IV: increasingly phallic clitoris, urethra-like urogenital sinus at base of clitoris, and complete labial fusionStage V: penile clitoris, urethral meatus at tip of phallus, and scrotum-like labia (appear like males without palpable gonads)
