cryptorchidism /crypt·or·chid·ism/ (krip-tor´kid-izm) failure of one or both testes to descend into the scrotum.cryptor´chid Cryptorchidism Occurs when a boy is born with one or both testicles in the lower abdomen rather than the scrotum. Known also as undescended testicles, it is the primary risk factor for testicular cancer. Mentioned in: Testicular Cancer, Undescended Testes cryptorchidism the state of being a cryptorchid. An improperly developed testis may never leave the abdomen, and it may not produce the hormones that induce secondary sex characters. A testis lodged in the canal may well produce these secondary sex characters, but cannot produce spermatozoa. Failure of both testicles to descend is uncommon. Usually only one testis is involved and the other produces sufficient spermatozoa to render the animal fertile. Called also rig. inherited cryptorchidism there is some evidence that cryptorchidism can be inherited in most species. cryptorchidism Undescended testicles A condition in which one or both testicles fail to move from the abdomen, where they develop before birth, into the scrotum; cryptorchidism uncorrected in early childhood is linked to azoospermia and ↑ testicular CA.

DESIGN: We obtained biologic samples from a prospective Danish-Finnish cohort study on cryptorchidism from 1997 to 2001. 4,14,17) Abnormalities of the reproductive system include cryptorchidism, hypospadias, hypoplastic uterus, and vaginal atresia. Risk factors placing a patient in a "high-risk group" for testicular cancer include a history of any one or more of the following: cryptorchidism (undescended testicle), orchiopexy (surgical correction of the undescended testicle), testicular atrophy (degeneration of the testicle), prior diagnosis of mumps, orchitis (inflammation of the testicle), inguinal hernia, hydrocele (fluid around the testicle), and previous testicular cancer (American Academy of Family Physicians, 1994). |
