Cryptorchidism
Cryptorchidism (derived from the Greek κρυπτός, kryptos, meaning hidden ὄρχις, orchis, meaning testicle) is the absence of one or both testes from the scrotum. It is the most common birth defect of the male genitalia. In unique cases, cryptorchidism can develop later in life, often as late as young adulthood. About 3% of full-term and 30% of premature infant boys are born with at least one undescended testis. However, about 80% of cryptorchid testes descend by the first year of life (the majority within three months), making the true incidence of cryptorchidism around 1% overall. Cryptorchidism is distinct from monorchism, the condition of having only one testicle.A testis absent from the normal scrotal position can be found:along the ""path of descent"" from high in the posterior (retroperitoneal) abdomen, just below the kidney, to the inguinal ring;in the inguinal canal;ectopically, that is, to have ""wandered"" from that path, usually outside the inguinal canal and sometimes even under the skin of the thigh, the perineum, the opposite scrotum, or the femoral canal;undeveloped (hypoplastic) or severely abnormal (dysgenetic);to have vanished (also see anorchia).About two thirds of cases without other abnormalities are unilateral; one third involve both testes. In 90% of cases an undescended testis can be felt in the inguinal canal; in a minority the testis or testes are in the abdomen or nonexistent (truly ""hidden"").Undescended testes are associated with reduced fertility, increased risk of testicular germ cell tumors and psychological problems when the boy is grown. Undescended testes are also more susceptible to testicular torsion (and subsequent infarction) and inguinal hernias. Without intervention, an undescended testicle will usually descend during the first year of life, but to reduce these risks, undescended testes can be brought into the scrotum in infancy by a surgical procedure called an orchiopexy.Although cryptorchidism nearly always refers to congenital absence or maldescent, a testis observed in the scrotum in early infancy can occasionally ""reascend"" (move back up) into the inguinal canal. A testis which can readily move or be moved between the scrotum and canal is referred to as retractile.
