This study aimed to investigate the protective effect of an antioxidant vitamin C against sodium arsenite-induced male reproductive toxicity as arsenic affects reproductive system by producing ROS. The treatment of mature guinea pigs with sodium arsenite (5mg/kg body weight/day) for period of 28 days reduced DSP, testosterone concentration and body, testis, epididymes and liver weight along with marked accumulation of arsenic in blood, liver, testis, epididymes and vas deferens.
