Erectile Dysfunction: Penile Prosthesis


Penile implants are a device that is implanted into the penis and is completely concealed within the body. There are multiple types of implants including inflatable and semi-rigid models. The surgery is typically performed as an outpatient and the device can be used in as little as 4 weeks.


Penile implants have been used since the 1970s and have the highest satisfaction rate among erectile dysfunction treatments.  They are more spontaneous than pills or injections, they offer a permanent treatment option, and allow the user to maintain an erection for as long as they desire.


There are several types of implants. There are inflatable models and semirigid (bendable) models.


The inflatable model features cylinders which replace the erectile tissue, a pump, and a reservoir. They offer the benefit of appearing flaccid until activated and can maintain an erection until you and your partner are satisfied. Once completed, they can be deflated again.


A semirigid or bendable prosthesis has less parts and is better for patients that may be unable to pump up a prosthesis. These devices are always rigid, but can bend up or down as needed. They may be harder to conceal than an inflatable prosthesis.
