Effect of Selective Dorsal Neurectomy on Erectile Function in Rats

Objective This study aimed to investigate the effect of penile selective dorsal neurectomy (SDN) on erectile function in rats. Methods Twelve adult male Sprague-Dawley rats (15 weeks old) were divided into three groups ( n =4 per group): in control group, rats received no treatment; in sham group, r...

Description
Summary:Objective This study aimed to investigate the effect of penile selective dorsal neurectomy (SDN) on erectile function in rats. Methods Twelve adult male Sprague-Dawley rats (15 weeks old) were divided into three groups ( n =4 per group): in control group, rats received no treatment; in sham group, rats underwent a sham operation; in SDN group, rats underwent SDN with half of the dorsal penile nerve severed. The mating test was performed, and the intracavernous pressure (ICP) assessed six weeks after the surgical treatment. Results At postoperative six weeks, the mating test revealed no significant difference in mounting latency and mounting frequency among the three groups ( P >0.05), while the ejaculation latency (EL) was significantly longer and ejaculation frequency (EF) lower in the SDN group than in the control and sham groups ( P 0.05). Conclusion SDN does not adversely affect the erectile function and sexual desire of rats, and at the same time it can reduce EL and EF, providing an application basis for SDN in the clinical treatment of premature ejaculation.
