ABSTRACT

The present study was aimed to investigate the effect of PVC on reproductive competence in adult male Wistar rats. Further, the study also encompasses the protective effect of trans-resveratrol on PVC-induced reproductive toxicity in rats. Adult male rats weighing 210-240 g were administered with either PVC at two different doses 100 and 500 mg/kg body weight, orally, daily for 60 days or resveratrol (20 mg/kg body weight/day) through gavage for 60 days on alternate days or both PVC (500 mg/kg body weight) and resveratrol. The results revealed significant reduction in the weights of reproductive organs, epididymal sperm count, viable-, motile-, and HOS-tail coiled sperm and testicular daily sperm production, steroidogenic enzyme activities, serum testosterone levels in PVC treated rats. Conversely the levels of lipid peroxidation increased significantly with a decrease in activity levels of antioxidant enzymes in the testis of PVC exposed rats. Exposure to PVC resulted in reduction in epithelial thickness and seminiferous tubule diameter. No significant changes in the selected reproductive variables were observed in the resveratrol alone treated control rats, whereas, co-administration of resveratrol and PVC resulted in a significant improvement in steroidogenesis and spermatogenesis and mitigated oxidative stress over PVC exposed rats.
