Effect of administration of aqueous extract of Massularia acuminata stem on intromission frequency of male rats. Values are means of five replicates ± SD; bars carrying letters, b, c, and d, different from their controls, a, on each day (i.e., days 1, 3 and 5) are significantly different at P < .05; bars carrying letters different for the same dose group at different days are significantly different at P < .05; bars carrying letters different from other dose groups are significantly different at P < .05.
