A penile prosthesis is a medical device implanted in a penis during a surgical procedure to enable an erection for satisfactory and satisfying sexual intercourse. The device is not used only in men with organic or treatment-resistant psychogenic impotence who fail to achieve and maintain an erection using erectile dysfunction drugs. A penile prosthesis is also used in the final stage of plastic surgery phalloplasty to complete female to male (transman) gender reassignment surgery as well as during total phalloplasty for adult and child patients that need male genital modification because of congenital anomalies, iatrogenic, accidental or intentional penile trauma, and micropenis.
The most common penile prosthesis has been in use for over 25 years. The current technology of these medical devices is quite safe and effective. Semirigid devices range from permanently erect ones that cannot be altered to malleable ones that can be bent into an unnoticeable position when appropriate.
Inflatable devices use fluid, not air, and are inflated or deflated on demand. Almost all current devices perform satisfactorily for a full decade before needing replacement. The leading manufacturers are American Medical Systems Inc., Mentor Corporation and Timm Medical Technologies.
A penile prosthesis can help men with erectile dysfunction that get no results from erectile dysfunction drugs. In addition, The British Journal of Urology International reports that unlike the limitations of metoidioplasty (metaoidioplasty) for female to male transsexual patients which usually results in an average penis size of 5 cm long and narrow width, current total phalloplasty neophallus creation using a musculocutaneous latissimus dorsi flap results in a long, large volume penis which enables safe insertion of any brand or model of penile prosthesis.
This same total phalloplasty technique enables male victims of minor to serious iatrogenic, accidental or intentional penile trauma injuries (or even total emasculation) caused by motor vehicle accidents, child abuse, animal bites, gun shots, burns, electrocution or self-mutilation to get large penises very suitable for penile prosthesis implantation so they can have successful sexual intercourse.
In some cases of genital reconstructive surgery, implantation of a semirigid prosthesis is recommended three months after total phalloplasty to prevent phallic retraction. It can be replaced later with an inflatable one.
Some studies indicate a partner satisfaction rate of 70% or less, due, some studies suggest, to heightened or unreasonable expectations. Many surgeons are now recommending that both partners be counseled pre-operatively regarding outcome and expectations.
It can be difficult to conceal that you have a prosthesis because the scrotal components are hard and irregularly shaped. Any woman feeling your scrotum will be puzzled. Manual stimulation can be painful.
Vacuum devices (penis pumps) and oral, suppository or injected erectile dysfunction drugs are not penile prostheses. Nor are dildos or any other externally operated device or sex toy.
