Abstract:
This study evaluated the effects of kola nut extract on sperm quality in male Sprague dawley rats. 30 adult male rats were used. These were divided into three groups: group A served as control, groups B and C received kola nut extract only (8mg/kg body weight), C served as recovery group. All the groups were treated for four weeks. Group C, which served as recovery group, was allowed to recover for another four weeks after the extract administration. Parameters of sperm quality: count, morphology and motility w ere insignificantly decreased. However, life/dead ratio was significantly decreased (p<0.05). The recovery group showed values that were insignificantly decreased but a bit closer to those of the control animals. This showed that the rats were able to recover to some extent after the extract administration. This indicates that consumption of cola nut has little, if any impact on semen quality.
