The risk of malignancy in the undescended testis is 4 to 10 ten times higher than that in the general population and is about one in 80 with a unilateral undescended testis and one in 40 to one in 50 for bilateral undescended testes. The peak age for this tumor is 15–45 years old.
If the pre-treatment testes are very small and there has been a history of undescended testes it might take longer to achieve sperm production. In these cases, assisted reproductive technology , such as sperm retrieval using testicular sperm extraction (TESE) and/or intracytoplasmic sperm injection (ICSI), might be required.
Orchiopexy is performed in the event of testicular torsion, a urologic emergency presenting with intense pain and often without inciting injury. [citation needed]While neonatal torsion occurs with no anatomic defect to account for its occurrence (occurring in utero or shortly after birth), adult torsion results from a bilateral congenital anomaly often called a "bell-clapper deformity", where ...

One testicle not descending into the scrotum during normal embryonic or fetal development (3–4% of 'normal' live births), also known as undescended testis or cryptorchidism. In this case the testis is within the abdominal cavity, somewhere along the normal route of descent – most commonly, within the inguinal canal .
The undescended testis is at increased risk of testicular torsion. [17] The mechanism for torsion in the undescended testicle is not fully understood, though it may be due to abnormal contractions of the cremaster muscle, which covers the testicle and spermatic cord and is responsible for raising and lowering the testicle to regulate scrotal ...
A ridgling (also spelled ridgeling), [1] or rig, is a cryptorchid; [2] a male animal with one or both testicles undescended, [1] usually describing a ram, bull, or male horse, [3] but cryptorchidism also can be an issue in dogs and cats. [4] Because the heat inside the body is too high for sperm to survive, an undescended testicle is non ...
Normally the testes begin its descent through the inguinal canal to the scrotum at 36 weeks’ of gestation and completed at birth. Failure in the course of testes descent will result in undescended testes (Cryptorchidism). Undescended testis is found in 4% of full-term infants but only 0.8% of males at the age of 1 year have true cryptorchidism.
