Erectile dysfunction (ED) is defined as the inability to achieve or maintain a sufficient erection to engage in sexual intercourse [1]. Erectile functions are related to the quality of life of individuals. Clinical research studies show that the erectile dysfunction caused by any reason negatively affects the quality of life of both men and their sexual partners [2,3]. ED etiologies include vascular, neurogenic, hormonal, metabolic, psychogenic, and medication side-effects [4].
