Q53 separates ectopic testis from undescended testicle, then distinguishes one side from both sides. Q54 covers hypospadias, in which the urethral opening sits below its normal location; its subdivisions name different locations and congenital chordee. Q55 covers other malformations of male genital organs, separated by the affected organ. Q56 separates indeterminate sex from male, female, and unspecified pseudohermaphroditism.
