Abstract:Erectile dysfunction (ED) is a significant clinical issue in the field of male health, with its pathophysiological mechanisms closely linked to vascular endothelial function. Recent studies have shown that ED is not only a manifestation of male sexual dysfunction but also an early biomarker of systemic vascular disease. Atherosclerosis, as the core pathological basis of cardiovascular disease, is significantly associated between its related evaluation indices and the development of ED. This study focuses on four clinically relevant atherosclerotic indices: the atherogenic index of plasma, atherogenic coefficient, Castelli's risk index-1, and Castelli's risk index-2. These composite indices objectively reflect the progression of atherosclerosis by assessing lipid metabolism disorders and vascular endothelial dysfunction, thereby contributing to the establishment of an early warning system for cardiovascular diseases. Furthermore, they provide novel clinical insights for the prevention and intervention of ED.
