Fig. 1. Representative charts of intracavernosal pressure (ICP). Increase in ICP by electrical stimulation was observed in the sham group (n=7; A). Increases in ICP were clearly lower in the chronic pelvic ischemia (CPI) model group (n=6; B). Increases in ICP were higher than the CPI but lower than the sham group in CPI with treated group (n=7, C). The upper curve is mean arterial pressure and the lower curve is ICP.
