I have no idea if it actually works, but I managed to find it mentioned on a site that looks like it's for urology doctors. According to that site, it's under review by the FDA in the United States (
http://urologytimes.modernmedicine.com/ ... reating-ed). The company that makes the machine, Medispec, is headquartered in Maryland. If you read further in the article, you'll find that it was authored by people with associations with the company, a clear conflict of interest. Here's what it says at the end. "Dr. Feldman is a consultant for Medispec. Several of his co-authors are consultants/advisers for Medispec, and one co-author is an employee of the company."
There are other articles on the National Institutes of Health website (
https://www.ncbi.nlm.nih.gov/). Just search for "Non-invasive low intensity shockwave therapy" or "LISWT" and read the articles that have to do with ED. Be sure to check for the Conflict of Interest statement at the ends of articles. Some authors have conflicts, but other articles don't mention that. I'm skeptical enough to believe that just because a conflict isn't mentioned, it doesn't mean that there isn't one.
Treating ED is a booming business, and guys will pay small fortunes to get treated with expensive drugs or anything else. If shock wave therapy works, it will probably appear in the US, despite big pharma and despite the cost of treatments. Guys will demand it. Many men probably won't have access to it, however, because ED prescriptions and treatments are generally not covered by insurance.
