Abstract:
Erectile dysfunction (ED) is the inability to achieve and maintain an erection. Erectile function is dependent upon complex interactions of neural and vascular pathways. A major neurotransmitter that facilitates erectile function is nitric oxide. Treatment of ED has expanded to include effective oral agents. Previous ED treatments have consisted of intracavernosal injection, transurethral dilators, and vascular constriction devices. Clinical management of ED will be presented with some discussion on the prostatectomy client.
