Role of alpha-tocopherol (vitamin E), beta-carotene and/or their combination as antioxidants against the toxicity of fenvalerate on blood hematology, free radicals, biochemical parameters, and semen quality were studied in male rats. Fenvalerate (20 mg/kg BW), vitamin E (100 mg/kg BW), beta-carotene (10 mg/kg BW), and vitamin E plus beta-carotene (100 + 10 mg/kg BW, respectively) were given alone or in combination with fenvalerate. The tested doses were given to rats every other day for 30 days. Results obtained showed that fenvalerate significantly (P < 0.05) induced free radicals in plasma and brain and insignificantly in liver and testes. While, vitamin E, beta-carotene alone and/or in combination decreased the levels of free radicals in plasma, liver, testes, and brain. The activities of glutathione S-transferase (liver), alkaline phosphatase (plasma and liver), aspartate aminotransferase (plasma, liver, and testes) and alanine aminotransferase (plasma and liver) were significantly (P < 0.05) increased due to fenvalerate administration. The activity of acetylcholinesterase was significantly (P < 0.05) decreased in brain and plasma, while plasma glucose, urea, creatinine, and bilirubin concentrations were significantly (P < 0.05) increased in rats treated with fenvalerate. Also, results showed a significant (P < 0.05) alterations in plasma proteins, hematological parameters, body weight, and relative weights of organs. Sperm concentration and motility (%) were significantly (P < 0.05) decreased, while dead and abnormal sperm increased in rats exposed to fenvalerate. Vitamin E, beta-carotene alone and/or in combination did not cause any changes in the investigated parameters, but improved semen quality and minimized the toxic effect of fenvalerate. The obtained results demonstrated the beneficial influences of vitamin E, beta-carotene alone and/or in combination in reducing the harmful effects of fenvalerate.
