The uncoupled endothelial NOS generates O, which reacts with NO to form ONOO, reducing NO bioavailability while activating pro-inflammatory pathways and exacerbating vascular endothelial damage, marked by diminished vasodilation, elevated vascular resistance, inflammatory activation and reduction of penile blood flow, ultimately impairing erectile function [62]
