Abstract

 
BACKGROUND: Wheat sprout contains a high amount of antioxidants, vitamins (especially vitamin E), minerals and phytoestrogen compounds. Use of medicinal herbs in reducing heavy metal toxicities has increased worldwide. In recent years, negative effects of lead on the male reproductive system and sperm fertility parameters have been shown broadly. OBJECTIVES: This study investigated the effects of wheat sprout extract (WSE) and vitamin E on sperm parameters and testicular oxidative stress in rats exposed to lead acetate. METHODS: Thirty-five rats were divided randomly into seven groups: G1 (control group) received 1 ml/kg/day of normal saline, G2 received 20 mg/kg/day of lead acetate, G3 and G4 received 100 mg/kg/day and 200 mg/kg/day of WSE respectively, G5 and G6 received 100 mg/kg/day and 200 mg/kg/day of WSE respectively with 20 mg/kg/day of lead acetate, and G7 received 100 mg/kg/day of vitamin E with 20 mg/kg/day of lead acetate. After 35 days, rats were sacrificed and blood, sperm, liver and testicle tissue samples were collected for histomorphological and histochemical studies. RESULTS: Results showed that count, motility and viability of sperms increased following the administration of 200 mg/kg/day of WSE (p<0.01). Histomorphological studies showed a significant increase in tubular differentiation index (TDI), Repopulation index (RI), number of Sertoli cells, and epithelium of seminiferous tubules in groups receiving 200 mg/kg/day of WSE (p<0.001). CONCLUSIONS: Results of the current study show that dose dependent WSE significantly prevents testicular toxicity and oxidative stress effects of lead acetate.
