Why would a surgical penile implant (penile prothesis) be used?

A surgical penile implant (also called a penile prosthesis) is a treatment option for men with erectile dysfunction (ED). The simplest type of prosthesis consists of a pair of bendable, silicone rods surgically implanted within the erection chambers of the penis. Today, many men choose a hydraulic, inflatable prosthesis that allows a man to have an erection whenever he chooses.

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.
