What is a penile implant?
A penile implant is a surgically implanted device that helps you get an erection, usually if you have erectile dysfunction (ED).
There are two types of penile implants:
- Inflatable penile implant: A pump in your scrotum (the pouch of skin behind your penis) allows you to get an erection whenever you choose.
- Non-inflatable penile implant: Bendable silicone rods in the erection chambers of your penis allow you to extend the rods into an erect position.
Other names for a penile implant include penis implant and penile prosthesis.
How does a penile implant work?
An inflatable penile implant consists of two cylinders, a reservoir and a pump that a healthcare provider surgically places in your body.
The provider inserts the cylinders into your penis. Tubes connect the cylinders to a separate reservoir under your lower abdominal (stomach) muscles. The reservoir contains fluid. A pump also connects to this system. It sits under the loose skin of your scrotum, between your testicles.
To inflate the implant (prosthesis), you press the pump in your scrotum. Pressing the pump doesn’t put any pressure on your testicles. The pump transfers fluid from the reservoir to the cylinders in your penis, inflating them to the level of hardness that you want. Once erect, you can maintain your erection for as long as you wish, even after an orgasm. When you want to stop being erect, pressing a valve on the pump returns the fluid to the reservoir, which deflates your penis.
A non-inflatable penile implant consists of two firm, flexible silicone rods.
This type of device doesn’t require pumping. To use the implant, you press on your penis to extend the rod into position. You can use the implant for as long as you wish — the hardness doesn’t change, even after an orgasm. After using the implant, you press on your penis again to push it back down.
Who is a good candidate for a penis implant?
Most people who are good candidates for a penis implant have ED or Peyronie’s disease. However, their condition can’t improve naturally or with other conservative medical treatments, such as medications or a vacuum constriction device (penis pump).
How long does the surgery take?
Both types of penile implant surgery are outpatient procedures, and are performed in 90 minutes or less. The patient can go home on the same day. To ensure adequate healing, the device should not be used for at least six weeks following the procedure.
How long does a penile implant last?
On average, penile implants last 20 years. When the implant wears out, it stops working. Your surgeon can revise it, usually by replacing it with a new implant.
