|A penile prosthesis is a treatment option for men with erectile dysfunction. These devices are either malleable or inflatable. The simplest type of prosthesis consists of a pair of (bendable) rods surgically implanted within the erection chambers of the penis. With this type of implant the penis is always semi-rigid and merely needs to be lifted or adjusted into the erect position to initiate sex. Many men choose a hydraulic, inflatable prosthesis, which allows a man to have an erection whenever he chooses and is much easier to conceal. It is also more natural.
A penile implant is usually used when there is a clear medical cause for ED and when the problem is unlikely to resolve or improve naturally or with other medical treatments. Sometimes a penile prosthesis is implanted during surgery to reconstruct the penis when scarring has caused erections to curve (Peyronie’s disease).
