Figure 5. Effect of HEE of leaves of C. pulcherrima on the percentage of sperm with acrosomal intactness status of (A) human and (B) rat for different incubation periods at different concentrations. Bars were expressed as mean±SEM (n=16), ANOVA followed by “Multiple-comparison Student’s two-tail ‘t’-test”. Points and bars with different superscripts (a-f) differ from each other significantly, p<0.05.
