Nitric Oxide and Other Neurotransmitters of the Corpus Cavernosum

  • Nestor F. Gonzalez-Cadavid
  • Jacob Rajfer


The physiology of erection comprises three distinct processes acting in concert: (1) increased arterial inflow, (2) active cavernosal smooth-muscle relaxation, and (3) decreased venous outflow. Cavernosal smooth-muscle relaxation appears to be the key event in a normal erection. Therefore, the cavernosal smooth muscle may be the critical site where erectile dysfunction begins.1
