Abstract:
1. The labelling pattern of the genital tract of bulls and rams injected peritesticularly with a single dose of [3H]ethylene dibromide was followed by autoradiography of histological sections of the testes and epididymides of treated animals castrated 6, 12, 24, 48 and 72 hr after injection. 2. The radioactivity in the genital tract of the bulls rose at 12 hr and again at 72 hr after injection, whereas in the rams the peak of radioactivity was found 6 hr and 12 hr after injection in the testes and epididymides, respectively. 3. In the bull testes the precursor was localized mainly in the cytoplasm of spermatids, whereas in the rams it was scattered in the seminiferous epithelium. 4. These results are discussed in connection with the susceptibility of bull and the immunity of ram spermatozoa to the spermicidal action of the above treatment found in previous studies. © 1981.
