Stem cell therapy in diabetic men with erectile dysfunction: a step closer to safe and effective regenerative technology

I would like to congratulate the authors on an interesting paper exploring the clinical outcomes of bone marrow-derived mesenchymal stem cells (BM-MSC) injections in diabetic men with erectile dysfunction (ED) (1). This prospective pilot, open-label single arm study showed an improvement in penile erection following 2 separate intracavernous injections of BM-MSC given 30 days apart, with sustained effect up to 12 months as evident by the IIEF-5 and EHS scores.
