Stem-cell regenerative medicine as applied to the penis

Purpose of reviewTissue engineering and regenerative medicine has emerged as a new scientific interdisciplinary field focusing on developing new strategies to repair or recreate tissues and organs. This review gathers findings on erectile dysfunction and, Peyronie's disease from recent preclinical and clinical studies under heading of stem-cell regenerative medicine.Recent findingsOver the last 2 years, preclinical studies on rat models demonstrated the tangible beneficial role of stem cells and stromal vascular fraction in the context of preventing fibrosis and restoring erectile function in different animal models of Erectile dysfunction and Peyronie's disease. There are not solid evidences in the clinical settings.SummaryLarge randomized, double blind clinical trials are needed to prove the efficacy of stem-cell therapy on human patients. Owing to the lack of solid evidences, the stem-cell therapy should be only administrated in a clinical research setting.
