The rats were randomly divided into 3 groups: A-C, each containing 6 rats. Fifty grams of fresh leaves of Ocimum gratisssimum were rinsed, thoroughly blended in 100 mL of distilled water and filtered through filter paper. A 10x10-4 and 5x10-4 mL kg-1 of the filtrate were administered to groups A and B, respectively thrice weekly for 5 weeks. Group C served as control and received distilled water. Histopathology revealed mild to severe congestion and edema as well as germinal tissue erosion of the seminiferous tubules. Spermatozoa motility, concentration, live-dead ratio and semen volume did not show significant changes (p>0.05). However, differences in spermatozoa abnormalities between control and tested groups were highly significant (p<0.01). Mean differences in sperm abnormalities between groups A (28.5), B (13.75) and the control were also greater than calculated Least Significant Difference (LSD) value of 2.146. These findings indicate antifertility properties of Ocimum gratisssimum. ER -
