A penile implant, also called a penile prosthesis, is a device placed surgically inside the penis that lets a man have an erection whenever he chooses. For men whose erectile dysfunction no longer responds to pills, injections or other treatments, or who cannot tolerate them, an inflatable implant is the definitive treatment. It does not depend on blood flow, nerve signals or medication timing, so it works in situations where everything else has stopped working.
That reliability comes at a real cost, and we want you to hear it first. An implant replaces the erectile mechanism permanently. The surgery takes up the space in the penis where natural erections happen, so once an implant is placed you will not be able to return to natural erections or to injection therapy. Mayo Clinic describes the procedure as lifelong and not reversible. For the right man that trade is well worth making, but it should be a considered decision rather than a first step.
Implants are one part of our broader sexual healthcare program, and our urologists place them only after a full evaluation and a frank discussion of every alternative.
Who is a candidate for a penile implant
Erectile dysfunction is the consistent inability to get or keep an erection firm enough for sex. In most men over forty the underlying cause is vascular: diabetes, high blood pressure, high cholesterol, smoking, and pelvic surgery or radiation all damage the small arteries and nerves that an erection depends on. Treatment usually moves in steps, from lifestyle changes and oral medication, to shockwave therapy or a vacuum device, to injections, and finally to surgery. The NIDDK likewise reserves implant surgery for men who have tried other options without improvement.
How a man responds to trimix injections is especially informative. Trimix acts directly on the erectile tissue, so if it stops producing a usable erection at doses that should work, it tells us the tissue itself can no longer hold an erection. That is not a dead end. It makes a man a good implant candidate. Implants are also a common solution for men whose ED follows prostate cancer treatment, and for men with Peyronie's disease who have both curvature and weak erections, since straightening and restoring rigidity can sometimes be addressed together.
How we evaluate you at NYMD Center
ED is often an early warning of vascular disease, because the arteries of the penis are smaller than those of the heart and tend to show damage first. Before any surgery we look at the whole man. The visit covers how the problem developed, what treatments you have tried and how each worked, your medications, and your cardiovascular risk factors, followed by a focused exam of the penis and scrotum.
Blood work usually includes hemoglobin A1c or blood sugar, a lipid panel and morning testosterone. Diabetes control matters in particular: poorly controlled blood sugar raises the risk of infection, and Mayo Clinic notes that an implant is not recommended for men with diabetes that is not well managed or with serious heart disease. We screen the heart as well, often with an in-office ECG, and coordinate with our internal medicine physicians when risk factors point that way. Low testosterone is treated on its own merits, since it affects libido and energy even though an implant does not depend on it.
Types of penile implants
Every option below is placed through a small incision and hidden completely inside the body. Nothing is visible from the outside, and the choice between them comes down to how natural you want the erection to feel, your anatomy and your manual dexterity.
Three-piece inflatable implant
This is the device most men choose. Two cylinders are placed inside the penis, a small pump sits in the scrotum, and a fluid reservoir is placed in the lower abdomen. Squeezing the pump moves fluid into the cylinders to create a firm erection; pressing a release returns the fluid to the reservoir so the penis becomes soft again. It gives the most natural erection in rigidity and in how flaccid the penis looks and feels at rest. The trade-off is more mechanical parts, which means more that can eventually wear out.
Two-piece inflatable implant
A two-piece device combines the pump and a smaller reservoir in the scrotum, so nothing is placed in the abdomen. It can suit men who have had extensive abdominal or pelvic surgery. The erection is firm, but the flaccid penis is usually a little less soft than with the three-piece design.
Malleable (semi-rigid) implant
Two bendable rods are placed in the penis. The penis is always firm and is bent up for sex and down the rest of the time. There is no pump to operate, which makes it a practical choice for men with limited hand strength or dexterity, and it has the fewest parts. The trade-off is that the penis never truly softens, which some men find harder to conceal.
Sensation, risks and the long term
An implant changes how an erection is produced, not the nerves of the penis. Cleveland Clinic states that an implant won't change the sensation on the skin of the penis or the ability to orgasm and ejaculate. Individual results vary, and we discuss your own situation before surgery.
Infection is the most serious risk. According to Mayo Clinic, most infections appear within three months of surgery, and a serious infection usually means the implant has to be removed. Careful blood sugar control, treating any urinary or skin infection beforehand and precise sterile technique all reduce this risk. Mechanical failure can occur over the years; Cleveland Clinic cites an average device life of about 20 years, and a broken part can be repaired or replaced with another operation. Many men also notice that the erect penis seems slightly shorter than the natural erections they remember, which both Mayo Clinic and Cleveland Clinic describe.
What to expect at your visit and after surgery
Your first appointment is a consultation, not a commitment. We review your history and test results, examine you, and show you the different devices so you can see and handle them. Many men bring their partner, which we encourage. If you decide to go ahead, we explain the preparation, including any medication changes and infection precautions, and the operation is performed by the group's urologists. Most men go home the same day or the next, and you will have follow-up visits to check healing. After several weeks, once the swelling has settled, we teach you how to use the device and confirm that it works as intended.

When to seek care urgently
After implant surgery, call our office promptly if you develop fever, increasing pain, redness, warmth or drainage at the incision, or a change in how the pump or penis looks, since these can be signs of infection or of a device problem. For men still using injections before a decision about surgery, an erection lasting four hours is an emergency that needs care right away.
Questions patients ask
Will a penile implant change how sex feels?
For most men, no. The implant changes how the erection is produced, not the nerves of the penis, and Cleveland Clinic notes that it does not change skin sensation or the ability to orgasm and ejaculate. Some men notice the erection seems slightly shorter than the natural erections they remember. We discuss what to expect in your own case before any decision is made.
Can I go back to pills or injections after an implant?
No. The implant permanently replaces the erectile mechanism, so natural erections and injection therapy are no longer possible afterward, even if the device is later removed. That is why we treat an implant as the definitive step after other options have failed or are not tolerated, and why we make sure you understand this trade-off before surgery.
Can other people tell I have an implant?
The inflatable implant is placed entirely inside the body. The cylinders sit within the penis, the pump in the scrotum and, with the three-piece device, the reservoir in the lower abdomen. The penis looks and feels soft at rest, and most partners cannot tell unless told. A malleable implant keeps the penis firmer at all times, which some men find slightly harder to conceal.
How long does a penile implant last?
Implants are durable, but they are mechanical devices and can fail over time. Cleveland Clinic cites an average lifespan of about 20 years. If a part fails, it can usually be repaired or the device replaced with another operation. A broken implant can also be left in place if a man does not want further surgery.
Who should not have a penile implant?
An implant is not recommended for a man with an active infection, poorly controlled diabetes or serious heart disease until those are addressed, because they raise the risk of complications. It is also not a first step: most men should try less invasive treatments first. Our evaluation looks at your heart, blood sugar and hormones before surgery is considered.
