Treatment with C. borivilianum root extract at both doses or glibenclamide lower the percentage of abnormal sperm as compared to non-treated diabetic rats. *p < 0.05 as compared to normal (control), †p < 0.01 as compared to diabetic group. n = 6 rats per group. 250C: 250 mg/kg/day C. borivilianum extract, 500C: 500 mg/kg/day C. borivilianum extract, 600G: 600 μg/kg/day glibenclamide.
