THE EFFECTS OF ALTERATIONS IN NITRIC OXIDE LEVELS IN THE PARAVENTRICULAR NUCLEUS ON COPULATORY BEHAVIOR AND REFLEXIVE ERECTIONS IN MALE RATS

Abstract

Altered NO levels in the PVN affected the frequency of reflexive erections, but not the mount rate. These studies contrast with previous observations of the effects of altered NO levels in the MPOA, and support the hypothesis that physiological specificity in the actions of NO on discrete brain nuclei may have important implications to erectile physiology and dysfunction.
