Abstract

Fenpropathrin (FNP) is a member of the synthetic pyrethroids. Herein, the present study was conducted to investigate, for the first time, the potentially harmful effects of FNP on the reproductive system of male rats. In addition, the prophylactic or concurrent influence of camel milk (CM) was assessed. Adult male rats were divided into five groups; control, vehicle control (oil), CM (2ml/rat/day), FNP (15mg/kg bwt/60 days), CM/FNP (prophylaxis) and FNP /CM (co-treated) groups. Sperm morphology, count, serum testosterone (TES), luteinizing hormone (LH) and follicle-stimulating hormone (FSH), thiobarbituric acid reactive substances (TBARS), total antioxidant capacity (TAC), superoxide dismutase (SOD), testicular enzymes, and comet assay analysis were estimated. In addition, histopathology, the ultrastructure of testicular tissue and apoptosis were evaluated. Reduced body weight and gonadosomatic index were observed in the FNP exposed group. TES, LH, FSH were markedly declined following FNP treatment. SOD and TAC concentrations were reduced while PC and TBARS were significantly elevated in FNP group indicating oxidative stress. Furthermore, FNP induced DNA damage and apoptosis in the testis which was evidenced histopathologically and by electron microscope examination. CM significantly counteracted FNP reprotoxic effects, particularly at the prophylactic routine (CM/FNP) than the co-exposure (FNP/CM) one. Conclusively, these findings verified that CM could be a potential candidate therapy against FNP reprotoxic impacts.
