Most normal-appearing undescended testes are also normal by microscopic examination, but reduced spermatogonia can be found. The tissue in undescended testes becomes more markedly abnormal ("degenerates") in microscopic appearance between two and four years after birth. Some evidence indicates early orchiopexy reduces this degeneration.
Funny Cide was a ridgling who was gelded and went on to become a champion race horse. 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.

The ectopic testis can be in the perineal region, the opposite side of the scrotum, the suprapubic region, the femoral region, or the superficial inguinal pouch. [1]The ectopic testis is initially normal, but if it is ignored after childhood, it may become small and soft, with spermatogenesis arresting and interstitial cell proliferation occurring.
Mutations in androgen receptor genes are highly implicated, as these are involved in penile development, testes descent, and testes development. [ medical citation needed ] Testicular germ cell cancer (TGCC) shows a strong genetic disposition, with the most significant gene variants being those linked to gonad formation and germ cell function.
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 ...

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.
The main form of treatment is laparotomy, a modern and minimally invasive type of surgery. Laparotomy properly positions the testes within the scrotum (orchidopexy) and removes Müllerian structures, the uterus, and fallopian tubes. [10] Occasionally they are unsalvageable if located high in the retroperitoneum. During this surgery, the uterus ...
