Abstract :Unilateral cryptorchidism was induced in adult rats for 5, 10 and 15 days and its influence on testicular morphology was investigated. In seminiferous tubules from abdominal testes the degenerative changes of germ cells was manifested in spermatocytes, spermatids and spermatozoa in Day 5 after the induction of cryptorchidism. These germ cells were almost absent by 15 days after the induction of cryptorchidism. On the other hand, spermatogonia and Sertoli cells were maintained in the failure of some morphological damages during experimental cryptorchidism. It is suggested that spermatocytes and young spermatids like spermatocytes, spermatids and spermatozoa were the most sensitive germ cells to body heat, whereas spermatogonia and Sertoli cells showed strong resistance to it. It was thought that multinucleated giant cells appeared at early time following artificial cryptorchidism might be responsible for the elimination of degenerated germ cells through phagacytosis by the cells.
