Benefits
You should be able to have an orgasm with a penile prosthesis if you were able to have one before the surgery, unless you suffer from another medical problem that might prevent it. These prostheses offer new hope to many men who suffer from erectile dysfunction and provide an option in cases where other treatments are inadequate or have failed.
Some scientific magazine articles have shown a 98% satisfaction in patients carrying these prostheses which have a 97.5% mechanical reliability, 5 years after first-time implants and some companies even offer a life-time return warranty on all of their penile prostheses.
Remember that erectile dysfunction is not an inevitable consequence of aging and is treatable.
