Intersex medical interventions these are rare in North America and Europe. Masculinizing surgery for completely virilized individuals with XX sex chromosomes and CAH is even rarer. Orchiopexy for repair of undescended testes (cryptorchidism) is the second most common surgery performed on infant male genitalia (after circumcision). The surgeon moves one or both testes, with blood vessels, from an abdominal or inguinal position to the scrotum. If the inguinal canal is open it must be closed to prevent hernia. Potential surgical problems include maintaining the blood supply. If vessels cannot be stretched into the scrotum, or are separated and cannot be reconnected, a testis
Congenital adrenal hyperplasia due to 3β-hydroxysteroid dehydrogenase deficiency an undervirilized male with normal sensitivity to testosterone. If the infant boy is only mildly undervirilized, the hypospadias can be surgically repaired, testes brought into the scrotum, and testosterone supplied at puberty. Management decisions are more difficult for a moderately or severely undervirilized genetic male whose testes are in the abdomen and whose genitalia look at least as much female as male. Male sex can assigned and major reconstructive surgery done to close the midline of the perineum and move the testes into a constructed scrotum. Female sex can be assigned and the testes removed and vagina enlarged surgically. A
