Аннотация:A quantitative analysis of spermatogenesis in mice and rats has shown that the response of various germ cells to cytotoxic effects of dipin or NMU. The spermatogonial compartment consisting of activily proliferating cells and some stem cells are the main targets for these drugs. The advanced primary spermatocytes, spermatids, and spermatozoa proved to be less susceptible. Species specific differences have been established in the character of destructive
and restorative processes during spermatogenesis
