A penile prosthesis is another treatment option for men with erectile
dysfunction. The simplest type of prosthesis consists of a pair of malleable
rods surgically implanted within the erection chambers of the penis. Today, many
men choose a hydraulic, inflatable prosthesis that allows a man to have an
erection whenever he chooses.
A penile implant is usually used when there is a clear medical cause for ED
and when the problem is unlikely to resolve or improve naturally or with other
medical treatments. Sometimes a penile prosthesis is implanted during surgery to
reconstruct the penis when scarring has caused erections to curve.
How does the penile prosthesis work?
The inflatable penile prosthesis consists of two cylinders--a reservoir and
a pump--that are placed surgically in the body. The two cylinders are inserted
in the penis and connected by tubing to a separate reservoir of fluid. The
reservoir is implanted under the groin muscles. A pump is also connected to the
system and sits under the loose skin of the scrotal sac, between the testicles.
To inflate the prosthesis, the man presses on the pump. This does not involve
putting pressure on the testicles. The pump transfers fluid from the reservoir
to the cylinders in the penis, inflating them. Pressing on a deflation valve at
the base of the pump returns the fluid to the reservoir, deflating the penis.
What is sex like with the prosthesis?
When the penis is inflated, the prosthesis makes the penis stiff and thick,
similar to a natural erection. Most men rate the erection as shorter than their
normal erection, however, newer models have cylinders that may increase the
length, thickness and stiffness of the penis.
A penile prosthesis does not change sensation on the skin of the penis or a
man’s ability to reach orgasm. Ejaculation is not affected. Once a penile
prosthesis is put in, however, it may destroy the natural erection reflex. Men
usually cannot get an erection without inflating the implant. If the implant is
removed, the man may never again have natural erections.
Do the implants work?
About 90%-95% of inflatable prosthesis surgeries are successful, meaning the
implants produce erections suitable for intercourse. Satisfaction rates with the
prosthesis are very high, and typically 80%-90% of men are satisfied with the
results and say they would choose the surgery again.
Is the implant safe?
No surgery is totally free of possible complications. Complications
associated with penile implants include:
- Uncontrolled bleeding after the
