The incidence of intersexuality in patients with hypospadias and cryptorchidism.

The incidence of intersexuality was determined in 45 patients with cryptorchidism and hypospadias seen between 1952 and 1975. Including patients with ambiguous genitalia the incidence was 53 per cent. When patients with ambiguous genitalia were excluded, providing a group more representative of the patient population usually seen by the urologist, a diagnosis of intersexuality was made in 27 per cent. The concomitant occurrence of hypospadias and cryptorchidism should alert the urologist to evaluate the patient for the presence of intersexuality.
