Acrylamide is a proved toxin for testicular function, found in food when heated for long period of time. Green tea (Camellia sinensis) is a potent antioxidant; the aim of this study was to investigate the protective effect of green tea extract against the toxic effects of acrylamide in rat testes. Methods: acrylamide was administered orally to rats in different doses and also the extract of green tea was administered orally to different groups of animals in combination with the acrylamide. The weight of animals, testosterone hormone level and histopathological effect upon testicles were evaluated. Results: Testosterone hormone level in serum, and histopathological findings were significantly improved with the co-administration of green tea extract with the acrylamide. Green tea extract reversed all the toxic effects of acrylamide even in high dose for long period (90 days). Conclusion: Green tea extract is a potent antioxidant antidote for the acrylamide toxic effects upon testicular function. © 2013 Wiley Periodicals, Inc. Environ Toxicol 29: 1155–1161, 2014.
