Erectile dysfunction or impotence, as it is normally called, is the most common cause of sexual frustration among men. The common treatments for erectile dysfunction are prescription medicines, penile injections, surgery or implant, and vacuum therapy. Among the four treatments, the latter is the cheapest and non-invasive. One of the known vacuum therapy treatment is the Encore Premium Vacuum Therapy System. This treatment system promises to provide men with a non-surgical option for erectile dysfunction. The Encore Revive Premium includes the following: body shield, vacuum pump, penile cylinder, constriction rings, and mounting cone. The penis is inserted into the cylinder making sure that it is pressed against the body before inserting the vacuum pump on the other end. Revive Premium claims to be very easy to use because of its re-engineered one-hand operation design.
