I had read about it several years ago, and when I consulted a new urologist about it after he mentioned they had a machine, he spoke fairly negatively and basically said it didn't work. A couple of years ago, I saw an ad for a company in a nearby town that advertised it. I did a consult with them and ended up buying a package of 6 sessions spaced two weeks apart for 1700.00 in advance. I wrote a few blog entries about those treatments if you're interested in reading them......

In retrospect, I would say that I wouldn't regard it as a screaming success - I may have gotten some benefit from it, but it wasn't the best thing that I ever found as ED treatment. I will say though, that it was really titillating to be lying there, naked and fully shaved (which is necessary) and having an attractive lady handling and working on my equipment. The treatments last about 15 minutes each. I came away from the experience a bit disappointed by the results, but having really enjoyed it as entertainment. The girl was quite honest with me in the initial consult when I made the decision to try it - If you have mild or moderate ED, you may get some benefit from the treatment, but if you're heavily impacted by ED and completely dead in the water, don't expect miracles.
