The aim of the current work was to compare the roles of caffeine and antioxidants in prevention of cadmium-induced testicular damage when given, in addition to cadmium, in adult male albino rats. Histopathological and ultra-structural examination as well as biochemical and molecular assessments were done. Cadmium chloride (4 mg/kg body weight) was administered via oral gavage from day 21 to 28 of the experiment. Caffeine (25 mg/kg) via intra-peritoneal injection and antioxidant preparation (Antox) 10 mg/kg via oral gavage were given as a pre-treatment for 21 days and concomitantly with Cd from day 21 to 28. Real-time PCR was done for determination of 3, 17 β hydroxy steroid dehydrogenase steroidogenic acute regulatory protein, caspase-9 and mitofusin 1,2 gene expression. Testosterone level, glutathione S-transferase enzyme activity, reactive oxygen species, malondialdehyde and superoxide dismutase were measured spectrophotometrically by ELISA. Histological and ultra-structural evaluation revealed disturbance of normal architecture, vacuolisation and necrosis. Vascular dilatation and congestion and collagen fibre deposition were present. A statistically significant difference was seen in all parameterswhen caffeine and antioxidants were given against cadmium-induced testicular injury. Overall, we conclude that both caffeine and antioxidants have the ability to reverse cadmium-induced testicular injury when given as pre-treatment prior to cadmium exposure.
