The effects of aqueous extract of Enantia chlorantha
were studied on sperm motility, viability and counts in
adult albino rats. Oral administration of 50 and 100 mg/kg
body weight of the extract daily for a week caused
dose-dependent changes in the sperm motility and viability
without a significant change in the sperm counts. There was
a significant increase in sperm motility and viability (P
<0.05) and an insignificant increase in sperm counts at 50
mg/kg body weight. However, an insignificant increase (P
>0.05) in sperm motility, and viability was observed at 100
mg/kg body weight. The results suggest that low doses of
E. chlorantha could improve sperm quality.
