RESUMO
Benznidazole is used extensively throughout Latin America as an antiparasitic chemotherapeutic agent against chagasica infection. We have shown that rats chronically treated with 80 mg benznidazole Kg-1 day-1 for 30, days present severe testicular atrophy and arrest of spermatognesis. In the present experiments, plasma levels of testosterone (T), luteinizing hormone (LH), follicle stimulating hormone (FSH) and prolactin (Prl- were inbestigated in rats receiving 10, 40 and 80 mg benznidazole Kg-1 day-1 for 30 days. No significant change in T, LH or Prl levels was observed in treated rats (P > 0.05). Plasma FSH concentration, however, was markedly invreased (P < 0.05 by benzidazole treatment (40 and 80 mgKg-1 day-1) and remained high for 90 days after drug treatment was discontinued
