Shocking the penis with sound waves may help those who have severe erectile dysfunction that has not respond well to drug treatments, a new study finds.
Among men in the study, "extracorporeal shock wave therapy" significantly improved sexual function, the researchers said. The patients continued to see improvements two months after the treatment had stopped, and close to 30 percent of them achieved normal sexual function and no longer required medications.
Extracorporeal shock waves have been used to break up kidney stones, but the sound waves used in the study to treat erectile dysfunction (ED) were much less intense, the researchers said. No men reported pain or adverse events during treatment.
