Figure 1: Erectile function evaluation. The ratio of maximal intracavernous pressure (Max ICP) and mean systemic arterial pressure (MAP) was shown to evaluate erectile function in each group. (a) Representative ICP in response to electrical stimulation of the cavernous nerve at 5 V in Sham group, NC group, EGCG10 group, and EGCG100 group. (b) Statistical chart of Max ICP/ MAP ratio. Each bar depicted the mean values (± standard deviation) from n = 10 animals per group. *P < 0.05 versus NC group, **P < 0.01 versus NC group, ##P < 0.01 versus Sham group.
