Intracavernous pressure (ICP) during cavernous nerve (CN) electrostimulation at 4 weeks after surgery. a-d Representative ICP responses for the sham group, CNI rats stimulated 4 weeks after IC injection of PBS, MSCs, and MSC-Exos. The colored bar denotes the 50 s CN electrical stimulation. e, f The ratios of the total ICP (area under the curve) and maximal ICP to MAP are recorded. Each bar depicts the mean ± standard deviation from n = 8 animals per group. *p < 0.01 compared with the PBS vehicle group
