Sperm total antioxidant capacity (TAC). TAC was reduced in diabetic rats as compared to normal, non-diabetic rats. Administration of C. borivilianum root extract at 250 and 500 mg/kg/day and glibenclamide in diabetic rats resulted in higher TAC as compared to non-treated diabetic rats. 250C: 250 mg/kg/day C. borivilianum root extract; 500C: 500 mg/kg/day C. borivilianum root extract, 600G: 600 μg/kg/day glibenclamide. n = 6 per treatment group, *p < 0.05 as compared to normal, non-diabetic control rats, †p < 0.05 as compared to non-treated diabetic rats.
