Investigations by Moore (1924) were among the first to show degeneration of seminiferous elements of the mammalian testes during cryptorchidism. Since that time, a number of experiments have demonstrated that biochemical and metabolic changes occur in the cryptorchid testis, including changes in respiration (Tepperman, Tepperman & Dick, 1949), glucose metabolism (Free, Vera Cruz, Johnson & Gomes, 1968), lipid levels (Fleeger, Bishop, Gomes & VanDemark, 1968) and gas tensions (Cross & Silver, 1962). Alteration in blood gas tensions has been associated with testicular degeneration (Free & VanDemark, 1968; Matteo & Nahas, 1963; Waites & Setchell, 1964) suggesting that a relationship may exist between cryptorchidism, gas tensions in the testis and tubular damage. The present study was undertaken to determine the effects of short-term cryptorchidism on oxygen tension in the rat testis. |
