title: [Pathogeneses of erectile dysfunction after rectal cancer treatment].
abstract: Rectal cancer is a common malignancy in the alimentary tract with an increasing incidence, the current treatments of which include surgery, radiotherapy, chemotherapy, and integrated comprehensive options. Sexual dysfunction, especially erectile dysfunction (ED), is one of the commonest complications in men after rectal cancer treatment and is generally attributed to the damage to the pelvic autonomic nerves. However, recent studies show that ED after rectal cancer treatment is a complex pathophysiological process associated with neurogenic, vasculogenic, and psychological factors. This article reviews the pathogeneses of ED after rectal cancer treatment in order to provide some theoretical evidence for its prevention and treatment.
