Whether the fungicide carbendazim affects the meiotic spermatocytes and consequently induces chromosome aberrations in the spermatids was determined in the adult rat testis using the micronucleus test. Round spermatids containing micronuclei (MN) were significantly increased in number at stages I and V on days 1 and 4.5 after treatment with carbendazim (100 mg/kg), respectively (p<0.05). Immunocytochemistry indicated that approximately 68% of the carbendazim-induced MN contained kinetochores.
