ED Treatment – Penile Prostheses

A penile prosthesis is a medical device that is implanted into a man’s penis, usually as an outpatient surgical procedure.  Finding a satisfying solution to erectile dysfunction can be a life-changing event for many men and their partners.  Research shows that penile prostheses are more satisfying than other common treatment options.

Benefits and Risks of Penile Prostheses

More than 300,000 men have returned to an active, satisfying sex life, thanks to penile prostheses.

But like any surgical procedure, there are benefits and risks to be considered.


  • Offers a long-term solution to ED
  • Provides the ability to have an erection anytime you choose
  • Allows for greater spontaneity when the mood strikes
  • Enables you to maintain an erection as long as you desire
  • Eliminates the need for costly pills or shots
  • Feels natural during intercourse
  • Does not interfere with ejaculation or orgasm


  • If an infection occurs, the prosthesis may need to be removed.  Infection rates have decreased to 1 to 3% but may be up to 5% in diabetic men.
  • Penile length may decrease slightly.  Patients need to have realistic expectations since the penis may be shorter than you remember due to chronic scarring or development of previously unrecognized penile curvature.
  • May be subject to mechanical failure. Mechanical failure in approximately 10% of cases over 10 years may necessitate a part replacement.


How The Penile Prosthesis Works 

Three-Piece Inflatable Penile Prosthesis


Types of Penile Prostheses 2

The three-piece, fluid-filled inflatable prosthesis features a pair of cylinders implanted in the penis, a pump implanted in the scrotum, and a reservoir implanted in the lower pelvis.  When the fluid is pumped into the cylinders from the reservoir, it creates an erection that provides rigidity and girth expansion. 



          -Totally concealed in body. Nobody else will know it has been implanted.

          -Like a natural erection

          -Device is inflated to provide rigidity and deflated for concealment

          -When deflated, the cylinders are soft and flaccid

          -92 percent patient satisfaction rate


          -Requires some manual dexterity


Two-Piece Inflatable Penile Prosthesis


Types of Penile Prostheses 1

The two-piece inflatable prosthesis consists of a fluid-filled pair of cylinders implanted in the penis and a small pump implanted in the scrotum.   To get an erection, you simply squeeze and release the pump several times.  When the fluid is pumped into the cylinders, it creates an erection that provides rigidity.  This implant is typically reserved for patients with prior extensive pelvic or abdominal surgery.


          -Totally concealed in body

          -Simple to use

          -One-step deflation

          -Device is inflated to provide rigidity and deflated for concealment

          -90 percent of partners would recommend it to other couples


          -Requires some manual dexterity             

          -Cylinders may remain partially filled with fluid when deflated


Semirigid or Malleable Penile Implant


Types of Penile Prostheses 3

This implant is generally reserved for patients with tremor or poor manual dexterity, such as men with Parkinson’s disease, quadriplegics, or the elderly.

Semi-rigid penile implants are less commonly utilized than the inflatable penile prostheses. The semi-rigid rods are always firm.  This prosthesis is used by bending the penis away from the body to create and erection and then bent toward the body to conceal the device.


          -Semi-rigid implants are less complicated and easier to surgically implant than inflatable devices

          -Have less risk of mechanical failure


          -A penis that is always slightly rigid

          -Creates an erection that is not as naturally rigid as with an inflatable device

          -More difficult to conceal than an inflatable implant
