Gamendazole produced 100% antispermatogenic effects at 25 mg/kg i.p. in rats, whereas 200 mg/kg was fatal for 60% of rats tested. Since gamendazole produced 100% efficacy, it was tested orally. At a dose of 6 mg/kg, 100% of rats were infertile 4 weeks after a single administration. Complete infertility was maintained for 2 weeks, followed by complete recovery in 4 of 7 rats. The other 3 never recovered fertility. Upon dosing 6 mg/kg orally for 7 days, it produced similar infertility results, but only 2 of 7 rats recovered fertility. There were no abnormalities in rates of conception or abnormal conception in rats who recovered fertility.Pathology reports were conducted on gamendazole treated rats. At 25 mg/kg i.p., 6 mg/kg oral, and in animals that survived 200 mg/kg i.p., there were no remarkable findings, with no evidence of inflammation, necrosis, tumors, or hemorrhage. There was also a lack of observable behavioral effects at 25 mg/kg i.p., 6 mg/kg oral, and in animals that survived 200 mg/kg i.p. Gamendazole treatment had no effect on testosterone levels, and was reported to affect Sertoli cell function, leading to decreased levels of inhibin B. Low levels of inhibin B were correlated to the infertility of the rat."@en }
