The aim of this work was to study the alleviative role of betaine versus arsenite-provoked alterations in testis oxidative status and circulating androgenic indices. Twenty-four adult male rats (204.5 ± 21 g) were divided into four groups, equally. Control group was given basal diet and tap water. Group 2 rats received arsenite (100 mg/L) in drinking water. Rats in group 3 received betaine (2% of the diet) during arsenite exposure. Group 4 received betaine at 2% of the diet during study period (30 days). The results revealed significant decrease in testicular glutathione peroxidase, catalase and glutathione in arsenite-treated animals relative to controls. Significant increase in testicular malondialdehyde was also detected in arsenite-exposed group. Concurrent administration of betaine with arsenite significantly increased glutathione and catalase amounts in comparison with arsenite group. Arsenite exposure resulted in a significant decrease in plasma testosterone and dihydrotestosterone levels over control rats, whereas supplementation of betaine augmented the hormones concentrations to the levels that had no significant difference in comparison with controls. Concentration of all measured oxidative status and hormonal variables in the betaine plus arsenite and betaine groups was not significantly different relative to controls. Taken together, betaine may be proposed as an alleviative agent against arsenite-induced male reprotoxicity.
