Detailed description: Erectile dysfunction is defined as the persistent inability to attain and maintain an erection enough to permit satisfactory sexual performance. Although ED is a benign disorder, it may affect physical and psychosocial health and may have a significant impact on the quality of life of sufferers and their partners.

According to the underlying causes, ED can be classified as psychogenic, endocrinologic, neurogenic, and vasculogenic. Vasculogenic erectile dysfunction is defined as an inability to get or keep an erection firm enough for sexual intercourse due to diseases such as diabetes mellitus and atherosclerotic vascular occlusive disease .

ED has been reported to occur in ≥50% of men with DM worldwide. It is usually present within 10 years of diagnosis of DM. The incidence of ED was reported to be higher in men with DM than for men without DM and up to 12% of men who present with ED were found to have previously undiagnosed DM.

Low-intensity extracorporeal shock wave therapy (Li-ESWT) was used in both in vitro and in vivo studies and the results showed that this energy can stimulate angiogenesis. The idea of applying Li-ESWT to the penis came from animal studies in which Li-ESWT was applied to the myocardium of pigs, where it has been reported that there was an improvement in ischemia-induced myocardial dysfunction.

Low-intensity extracorporeal SW therapy (Li-ESWT) of the penis would improve penile blood flow and endothelial function by stimulating angiogenesis in the corpora.

Oral phosphodiesterase-5 inhibitors (PDE-5 inhibitors), such as sildenafil and tadalafil, are usually the first-line treatment of erectile dysfunction. They are effective in a wide range of etiologies including cardiovascular disease, diabetes, and hypogonadism.

Contraction of the ischiocavernosus participates in the process of enhancing erectile rigidity by compressing the roots of the corpora cavernosa and inducing short-term suprasystolic intracavernosal pressures.

Further, bulbospongiosus contraction leads to temporary engorgement of the glans penis and corpus spongiosum and results in similar short-term increases in intra spongiosal pressures.
