The Ki-67 of the dorsal penile nerves’ major and minor branches on different days after bilateral cavernous nerve injury. Proliferative marker of Ki-67 in the DPNs’ main (upper panels) and minor (lower panels) branches. The positive cells (red arrow) were greater in all of the BCNI groups, compared to the sham group. Moreover, the positive cells were greatest on the 28th day after BCNI. Magnification is 400×. DPNs = Dorsal penile nerves. BCNI = Bilateral cavernous nerve injury.
