Incidence of spermatids, sperm and Sertoli nuclei at different times following 2560 r of x-rays. The histological material was processed, and slides were stained, as described earlier (Bryan and Gowen, 1956). As in our previous work, the procedure of Chalkley (1943) was used to obtain estimates of the relative areas of the tubules occupied by each stage of spermatogenesis. This procedure was also used to provide data with respect to spermatogonial and non-spermatogonial necrosis during the first 24 hours following exposure to x-rays. RESULTS The data obtained are summarized in Tables I-III. Data pertaining to both strains are presented together for ease of comparison. In Table I all values are.
