Figure 3: Evaluation of erectile response at 10.0 V. (a) The Sham group, the BCNI group, the BCNI + Losartan group, and the neurectomy group; n = 12 in each group. (b) Results of cavernous electrostimulation in the four experimental groups are expressed as ICP/MAP. Bar graphs represent mean ± standard deviation. **P < 0.01, the indicated group compared with the Sham group; #P < 0.05 and ##P < 0.01, the indicated group compared with the BCNI group. BCNI: bilateral cavernous nerve injury; ICP: intracavernosal pressure; MAP: mean arterial pressure.
