[Intracavernosal pressure measurement technology in the animal model of erectile dysfunction]

Penile erection is a primarily aneurovascular event,which depends on the relaxation of the corpus cavernosum smooth muscle cells and engorgement of the penis with blood. The compression of the subtunical venular plexus results in venular blockage.The intracavernosal pressure( ICP) is close to 5-7 mmHg in the flaccid state and rapidly increases to more than 100 mmHg in the tumescence phase. In the study of the animal model of erectile dysfunction,ICP measurement is the golden standard for evaluation of erectile function. In the recent years,telemetric technology has been successfully applied in monitoring the changes of rat ICP abroad,but no such report is seen domestically. This paper presents an overview on the development of the ICP measurement technology.
