A penile prosthesis, or penile implant, is one of the oldest effective treatments for the condition of erectile dysfunction. The medical device which is surgically implanted within the corpora cavernosa of the penis during a surgical procedure, provides the highest levels of patient and partner satisfaction of all available treatment options. The device is indicated for use in men with organic or treatment-resistant impotence or erectile dysfunction that is the result of various physical conditions such as cardiovascular disease, diabetes, pelvic trauma, Peyronie’s Disease, or as the result of prostate cancer treatments. Less commonly, a penile prosthesis may also be used in the final stage of plastic surgery phalloplasty to complete female to male gender reassignment surgery as well as during total phalloplasty for adult and child patients that need male genital modification.
