The response of hamster testis to the administration of 450mg/kg procarbazine (PCB) over a period of 4 weeks was evaluated. Flow cytometry was used to investigate changes in cell populations in testicular single cell suspensions and to correlate these changes with those observed in histological sections. PCB caused significant decrease in testicular and epididymal weight and a drastic reduction in haploid cells and spermatogenic arrest, demonstrating variation among the test animals. The results obtained confirm previous observations concerning detrimental effects of PCB upon spermatogenesis in species such as the rat and mouse, though its effect on hamster testis is milder and does not include the germinal stem cells. The histological evaluation of the testis showed a good correlation with flow cytometric evaluation, emphasizing the usefulness of this method in providing quantitative and rapid results.
