The rat model of erectile dysfunction caused by the injury of the cavernous nerve / 医学研究生学报

ABSTRACT

Objective:To establish a rat model of erectile dysfunction caused by the injury of the cavernous nerve. Methods:Rats topographical anatomy were done for identifing the cavernous nerve and major pelvic ganglion and pelvic nerve and hypogastric nerve .Polygraph intracavernous pressure of the models were detected continuously and evaluated. Results:Erectile process was controlled by erectile nerve. Major pelvic ganglion includes two inflows,they are called pelvic nerve and hypogastric nerve. The largest outflow is cavernous nerve. The injury of the cavernous nerve will lead to erectile dysfunction. Conclusion:Rat can be an ideal animal model for studying the erectile dysfunction caused by cavernous nerve injury. The neuvological mechanism of erectile dysfunction can be evaluated with determination of intracavernous pressure.
