The passageway through which the testis and spermatic cord descend is called the inguinal canal. Failure of a testis to descend into the scrotum is called cryptorchidism. The testis is divided internally into about 250 compartments or lobules, each of which contains one to three small convoluted tubules, within which spermatozoaare produced.
