Oats (Avena sativa L.), which are used in foods, are a potential economically viable source of oil. The purpose of this study was to determine the efficiency of oats oil to alleviate oxidative damage of testis induced by deltamethrin, which is a pyrethroid pesticide that exerts a wide range of effects on non-targeted organisms. The reprotoxicity caused by orally administered deltamethrin (DEL) to mice can be effectively antagonized by the beneficial effects of oats oil (OO) as an antioxidant. Thirty-two male albino mice were divided into four equal groups : a control group, a group of mice given deltamethrin (5 mg per kg b.w.), a group administered deltamethrin after receiving oats oil (6 g per kg b.w.), and a group receiving only OO. Exposure to deltamethrin at a dose of 5 mg per kg b.w. per day caused oxidative stress in testis, proven by a decrease in the epididymal sperm count and motility, an increase in the number of abnormal morphologies in spermatozoa and a significant increase of lipid peroxidation (LP) in the testis when compared to control animals. Co-administration of oats oil to the DEL-treated mice ameliorated the testicular biochemical parameters as well as the histological impairments in testis. We concluded that oats oil ameliorated the toxic effects of deltamethrin in testis explored by reduced LP and improved total sperm density, motility and morphology in mice spermatozoa, suggesting its role as a potential antioxidant.
