For a man with severe erectile dysfunction that no pill or injection can fix, a penile implant can be life-changing — restoring intimacy, confidence, and a sense of wholeness. But for decades, this remarkable surgery carried one silent, microscopic enemy: infection. The story of how surgeons have battled that threat over fifty years is one of the most inspiring tales of quiet, relentless progress in modern medicine.

In May 2026, while shadowing Professore Mohit Khera — a global leader in men’s health and prosthetic surgery — at the American Urological Association (AUA) 2026 meeting in Washington, DC, I attended a lecture that changed how I think about surgical innovation. It traced the journey from the high-infection days of the 1970s to today’s ultra-clean, DNA-guided operating rooms. Here is that story, told for everyone — followed by the part a history lecture does not cover: what none of this progress changes about the decision itself.

First, What Is a Penile Implant?

An inflatable penile prosthesis (IPP) is the definitive option for men with severe erectile dysfunction caused by conditions like diabetes, prostate cancer surgery, or cardiovascular disease — in cases where pills and injections no longer work. It is an elegant device hidden completely inside the body, made up of two cylinders placed in the erection chambers, a small pump tucked into the scrotum, and a fluid reservoir in the lower abdomen.

When a man wants an erection, he presses the pump, which moves fluid into the cylinders to create a firm erection. A release valve returns the fluid afterwards. Because everything is internal, it is invisible from the outside, and partners are generally unaware of it unless told.

But there is a catch. Because it is an implanted device, it has one unique vulnerability: bacteria. If germs settle on the device during surgery, they can form a protective shield called a biofilm. Once a biofilm forms, ordinary antibiotics cannot penetrate it — and the fix is another operation to remove the entire device. Preventing this has been the central problem of implant surgery for fifty years.

Era 1: The Wild West (Before 2001)

The early decades, from the 1970s through the 1990s, featured brilliant engineering but frustratingly high infection rates — especially in vulnerable patients such as those with diabetes, and higher still when a previous implant needed replacing.

Back then, surgeons cleaned the skin with a traditional iodine solution. It killed surface germs but had no lasting power. When an infection did strike, the options were grim: the device came out, the tissue scarred, and the penis shortened. The alternative was first reported at the AUA meeting in 1987 by Dr. Fishman, Dr. F. Brantley Scott and Dr. Selim — remove the infected device, wash the cavity thoroughly, and place a fresh one in the same operation. The approach was popularised in 1996 by Dr. Brant, Dr. Ludlow and Dr. John J. Mulcahy, and is still known as the Mulcahy salvage. It saved many men from losing length and function, but the irrigation solutions were harsh enough to damage healthy tissue as well as bacteria. Surgeons needed a way to kill germs without harming the patient.

Era 2: The Coated Device Revolution (2001–2010)

The new millennium brought two significant upgrades.

First, surgeons switched from iodine to an alcohol-based chlorhexidine skin preparation. High-quality studies showed it was better at preventing infection, because it binds to the skin and keeps killing bacteria for hours after the first incision.

Second, manufacturers turned the implant itself into part of the defence. One company coated its devices with antibiotics that slowly release into the surrounding tissue. A rival introduced a water-loving coating that lets surgeons dip the implant in an antibiotic solution of their choice right before insertion. The impact was striking: surgeons discovered that a surprising number of older, uncoated implants had silent, symptom-free bacteria living on them — and the coated devices markedly cut the rate of bacteria found during follow-up surgeries.

Era 3: The No Touch Technique (2010–2019)

With cleaner skin preparation and smarter devices, the next frontier was the operation itself. Even after the best skin cleaning, deep skin pores still harbour microscopic bacteria. If a surgeon’s glove or an instrument touched the skin and then the implant, those germs could hitch a ride straight into the body.

The answer was the No Touch technique. Before the implant is ever opened, the surgical area is covered with a sterile plastic drape. The surgeon works through a small opening, so the implant never touches the patient’s bare skin at any point. By physically isolating the device from the skin, the amount of bacteria detected during later surgeries dropped further still.

Era 4: The Modern Frontier — Smart Antiseptics and DNA Science (2020+)

This brings us to today’s era of tailored, molecularly guided surgery.

Antiseptics Return — But Smarter

As bacteria worldwide grow more resistant to antibiotics, surgeons have circled back to antiseptics — but with modern precision. Instead of the harsh, tissue-damaging chemicals of the 1990s, they use gentle, highly diluted antiseptic solutions. A leading example is a very low-concentration chlorhexidine rinse that clears the great majority of bacteria and fungi within minutes without harming human tissue. In hot, humid climates where fungal infections are more common, surgeons also routinely add antifungal medication right before the operation.

Reading the Bacteria’s DNA

Perhaps the most striking advance is the shift from old-fashioned lab cultures to next-generation sequencing (NGS). For over a century, identifying an infection meant swabbing the area, smearing it on a lab plate, and waiting days to see what grew — a method that misses many bacteria that will not grow in a lab.

NGS skips the lab plate entirely. It reads the raw DNA from the surgical site and matches it against a genetic database, identifying which bacteria are present within hours, even from tiny fragments. Researchers have found that different problems tend to carry different germ fingerprints: infected implants, eroded implants, and pure mechanical failures each tend to involve distinct organisms. With that information, surgeons have less need to guess which antibiotic to use. It is worth saying that this is still a developing field rather than a settled standard everywhere — which is itself a fair description of where the science sits today.

What Fifty Years of Progress Does Not Change

A story like this is genuinely encouraging, and it can also leave the wrong impression. Lower infection rates make a good operation safer. They do not make it a different operation, and three things are exactly as true in 2026 as they were in 1976.

• It is not reversible. Implanting the cylinders removes the natural erectile tissue. If the device is ever taken out, natural erections do not come back, and tablets or injections will no longer work either. This is the single most important sentence on the page.
• It is not a first step. An implant is considered after tablets, injections and other measures have been tried or are unsuitable — not instead of trying them.
• Every device eventually wears out. Modern prostheses last a long time, but they are mechanical, and a man implanted in his fifties should expect a replacement at some point. Revision surgery carries a higher infection risk than the first operation — which is precisely why the first one is done as carefully as this article describes.

Many men also notice some loss of length compared with the erections they had before erectile dysfunction developed. That is expected rather than a complication, and it is one of the things worth discussing properly beforehand. The full picture is set out on the penile prosthesis surgery page, and the specific question of replacing an existing device is covered in penile implant revision surgery.

What Infection Actually Looks Like

An article about infection prevention should tell you how to recognise one. Reporting it early is not a formality — it is often what decides whether the device can be saved or has to come out.

Contact the hospital the same day if you develop any of these after implant surgery:

• Fever or chills
• Redness that is spreading, or any discharge from the wound
• Pain that is increasing after the first few days rather than settling
• A scrotum that is tense or swelling quickly
• Inability to pass urine
• Any part of the device becoming visible or breaking through the skin — this is erosion and needs urgent assessment

And one that surprises people: an implant infection can appear months after the operation, as pain that never quite settles rather than a dramatic fever. If something has not felt right for weeks, that is worth a phone call rather than patience.

What You Can Do About Your Own Risk

Fifty years of progress happened on the surgical side of the table. The patient side matters too, and it is largely about the weeks before the operation rather than the day itself: blood glucose controlled as well as it can be, any urinary or skin infection treated and cleared beforehand, and smoking stopped if at all possible, since it impairs wound healing. Tell the team about any infection anywhere in the body before surgery, even one that seems unrelated. Afterwards, keep the device identification card, and tell any doctor, surgeon or radiographer about the implant before imaging, catheterisation or an operation — a urinary catheter in particular should not be passed by someone who does not know the device is there.

Why This Story Matters

Walking out of that lecture hall, I felt a real sense of gratitude. The beauty of medicine is not only in discovering the next big thing. It is in the willingness to look honestly at what we already do, find the flaws, and work relentlessly across decades to fix them. A complication that once caused stress and heartbreak for thousands of men has been systematically dismantled — through better skin preparation, clever device design, disciplined surgical technique, and genetic science.

It has not been eliminated, and any surgeon who tells you otherwise is selling something. Infection remains the complication that worries prosthetic surgeons most, and the risk is higher in men with diabetes, in men who are immunosuppressed, and in revision surgery. What fifty years of work has bought is a far better set of odds — and for the men who reclaim their intimacy and confidence through a penile implant, that is not an academic timeline. It is the reason the operation is offered with confidence today.

If you are struggling with severe erectile dysfunction that has not responded to other treatments, a penile implant may be worth discussing.

Domande frequenti

What is an inflatable penile prosthesis (IPP)?

An inflatable penile prosthesis is a surgically implanted device that allows men with severe erectile dysfunction to achieve an erection when pills and injections no longer work. It consists of two cylinders in the penis, a small pump in the scrotum, and a fluid reservoir in the lower abdomen. Pressing the pump moves fluid into the cylinders to create a firm erection. Because it is entirely internal, it is invisible from the outside. It is the definitive treatment for severe erectile dysfunction, but it is considered after other treatments rather than instead of them.

Is penile implant surgery reversible?

No. The device can be removed, but implantation permanently alters the natural erectile tissue, so natural erections do not return afterwards and tablets or injections no longer work. Improvements in infection control do not change this. It is the point to be most certain about before agreeing to the operation.

How common is infection after penile implant surgery today?

Far less common than it once was. Alcohol-based chlorhexidine skin preparation, antibiotic-coated devices, the No Touch surgical technique, gentle antiseptic rinses and DNA-based bacterial identification have all reduced it, and in experienced hands it is now an uncommon complication. It has not been eliminated, and the risk remains higher in men with diabetes, in men who are immunosuppressed, and in revision surgery.

What are the warning signs of an infected penile implant?

Fever or chills, spreading redness or discharge from the wound, pain that increases after the first few days instead of settling, a tense or rapidly swelling scrotum, inability to pass urine, or any part of the device becoming visible. Contact the hospital the same day rather than waiting for the next appointment. An implant infection can also appear months later as pain that never settles, and reporting it early is often what decides whether the device can be saved.

What is a biofilm, and why does it matter for implants?

A biofilm is a protective shield that bacteria can form on the surface of an implanted device. Once it develops, ordinary intravenous antibiotics cannot penetrate it, which means the infection usually cannot be cured with medication alone and the device typically has to be removed surgically. This is why preventing bacteria from ever reaching the implant during surgery matters so much.

What is the No Touch technique in penile implant surgery?

The No Touch technique is a surgical method designed to prevent the implant from ever contacting the patient’s bare skin, where bacteria live deep within the pores. The surgical area is covered with a sterile plastic drape, and the surgeon works through a small opening so the device is isolated from the skin surface. This simple but powerful innovation significantly reduced the bacteria detected during surgery.

Can I lower my own risk of infection?

To a degree, yes, and mostly in the weeks beforehand: blood glucose controlled as well as possible, any urinary or skin infection treated and cleared, and smoking stopped if you can, since it impairs wound healing. Tell the surgical team about any infection anywhere in the body before the operation, even one that appears unrelated.

Who is a good candidate for a penile implant?

A penile implant is generally considered for men with severe erectile dysfunction that has not responded to first-line treatments such as oral medications or penile injections. Common underlying causes include diabetes, complications after prostate cancer surgery, and cardiovascular disease. Because the operation is irreversible, the decision is made together with a urologist after a full assessment of health, expectations and treatment history.
