Cryptorchidism, also known as undescended testis, is the failure of one or both testes to descend into the scrotum.The word is from Ancient Greek κρυπτός (kryptos) 'hidden' and ὄρχις (orchis) 'testicle'.
Classical Roman law, that is Roman law until the end of the second century AD, did not contain the unus testis-rule according to current scholarly understanding, even though D. 22.5.12 [γ] – a passage of the Digest attributed to the early 3rd century Roman jurist Ulpian – had historically been understood as evidence for the existence of such a rule during this period.
The lower part persists as the gubernaculum testis ("scrotal ligament"). This ligament secures the testis to the most inferior portion of the scrotum, tethering it in place and limiting the degree to which the testis can move within the scrotum. Cryptorchidism (undescended testes) are observed in INSL3-null male mice.
[15] [16] Therefore, if the testicular artery is ligated, e.g., during a Fowler-Stevens orchiopexy for a high undescended testis, the testis will usually survive on these other blood supplies. [ 17 ] Lymphatic drainage of the testes follows the testicular arteries back to the paraaortic lymph nodes , while lymph from the scrotum drains to the ...
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.
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 .

Sertoli cells are specifically located in the convolutions of the seminiferous tubules, since this is the only place in the testes where spermatozoa are produced.
