Energy-Based Therapies for Erectile Dysfunction: Current and Future Directions.

Abstract

Energy-based therapies are novel treatments for erectile dysfunction that are thought to work by stimulation of tissue vasodilation, neoangiogenesis, and so forth. Low-intensity extracorporeal shock wave therapy (Li-ESWT) is the energy-based therapy with the most robust evidence basis demonstrating efficacy and safety. Among this evidence, randomized controlled trials (RCTs) evaluating Li-ESWT have largely been focused on responders to phosphodiesterase-5 inhibitors. Many of these RCTs have limitations including short follow-up durations, inconsistent protocols, and small sample sizes. Until more diverse patient populations are studied and these limitations are addressed, the use of Li-ESWT should remain limited to IRB-approved clinical research trials.
