Growth factor therapy and neuronal nitric oxide synthase

Abstract

Trauma to the cavernous nerve is a known cause of erectile dysfunction, with lengthy and often incomplete recovery. Using rat models, we have previously shown that injury to the cavernous nerves or ligation of pudendal arteries causes a significant decrease of neuronal nitric oxide synthase (nNOS) in the dorsal nerve of the penis and intracavernosal tissue as well as loss of erectile response to neurostimulation. Intracavernous injection of vascular endothelial growth factor or brain-derived neurotrophic factor facilitates the recovery of nNOS and erectile function. Studies are underway to elucidate the molecular mechanism of cavernous nerve regeneration and the potential of using growth factors to enhance the recovery of erectile function in patients after radical pelvic surgery.
