Morphological and Functional Evidence for the Contribution of the Pudendal Artery in Aging-Induced Erectile Dysfunction

In aged rats, erectile function was severely diminished when pudendal arteries had undergone marked phenotypic changes. Specifically, there was endothelial dysfunction and pathological remodeling of this vessel with age, characterized by medial thickening, impaired vasodilation and significantly reduced capacity for penile blood flow.
