Erectile dysfunction (ED) is a complex condition affecting men worldwide. Diabetes mellitus (DM) is one of the most common causes of ED. The prevalence of ED in DM varies around 35-85%. Recently, stem cell therapy has started to become the focus of experimental and clinical studies for the treatment of ED. Stem cells have been shown to be able to regenerate functionally damaged tissue, depending on the stimuli or signals received. Stem cells studies in experimental animals have been carried out using biomarker parameters, including VEGF, Bcl-2, E-selectin, cGMP, eNOS and have been shown to be successful in increasing cell survival and angiogenesis, stimulating antiapoptotic, proneurogenic, proinflammatory, and antifibrotic effects and improvements to these biomarker parameters. This study aims to determine the efficacy, mechanism of action, and safety of umbilical cord mesenchymal stem cells as a therapy for ED due to type 2 diabetes in human.
