Who Is Not a Candidate for a Penile Prosthesis?

Browse the content

Who is not a candidate for a penile prosthesis? Reversible erectile dysfunction, infections, or purely cosmetic reasons make the implant unsuitable—an experienced urologist must assess each case.

Some men who fall into the “not a candidate for penile prosthesis” group include those with reversible erectile dysfunction, active infections or aesthetic motivations. Read on for other contraindications.

What is a penile prosthesis and when is it indicated?

A penile prosthesis is an implant placed inside the penis when conventional impotence therapies fail. Other indications include:

  • Men who experienced severe side-effects with medication;
  • Patients who responded to injections or oral drugs for erectile dysfunction but no longer wish to rely on them;
  • Peyronie’s disease when curvature prevents penetration.

There are two types of prosthesis: inflatable and malleable.

The inflatable model has three cylinders inside the corpora cavernosa, plus a pump and a saline reservoir. When an erection is desired, squeezing the pump fills the cylinders.

A malleable prosthesis consists of two flexible rods that keep the penis constantly firm, allowing it to be positioned upward for intercourse and downward for rest.

Cases where a penile prosthesis should not be recommended

Although effective, the device is not for everyone. Men who should avoid a penile prosthesis include:

  • Those expecting penile growth, since the implant does not lengthen the penis;
  • Erectile dysfunction due to treatable factors—psychological causes reversible with therapy or hormonal imbalance.

Health conditions that prevent prosthesis surgery

Learn more about penile-prosthesis contraindications:

1. Uncontrolled diabetes

Unmanaged diabetes impairs healing, favours infection and weakens immunity.

2. Heart disease

Severe heart failure, uncontrolled arrhythmias and unstable angina raise cardiac-arrest risk and anaesthesia complications.

3. Advanced kidney failure

Kidney failure elevates potassium and hampers drug clearance, increasing side-effects.

4. Coagulation disorders

Any clotting problem heightens bleeding and postoperative haematomas.

5. Immunosuppression

Immunosuppression—from cancer, HIV, chronic kidney disease, chemotherapy, radiotherapy or transplants—raises systemic-infection risk.

6. Severe psychiatric disorders

Conditions such as bipolar disorder, major depression or schizophrenia may impair adherence to care.

7. Major penile anatomical changes

Late-stage Peyronie’s disease or priapism sequelae (e.g. erectile-tissue necrosis) can make implantation unfeasible.

Medical assessment before indicating a penile prosthesis

Evaluating candidacy ensures safety. The assessment includes:

Urological evaluation

  • Physical exam: penile anatomy, testes, prostate;
  • Erectile-dysfunction history: onset, duration, severity, prior treatments (oral drugs, injections, vacuum pump);
  • Clinical history: urological surgeries, trauma, Peyronie’s disease.

Laboratory evaluation

  • Glucose and HbA1c;
  • Free and total testosterone;
  • Renal function;
  • Lipid profile (urea and creatinine);
  • Coagulation panel;
  • Complete blood count.

Cardiovascular and anaesthetic evaluation

  • Electrocardiogram;
  • Echocardiogram and stress test.

Why choose a specialised surgeon?

Working with a penile-prosthesis specialist improves clinical outcomes and peri-operative safety. Key advantages include:

  1. Technical precision and lower risk of infection, bleeding or prosthesis displacement;
  2. Knowledge to select the right prosthesis type—inflatable or malleable;
  3. Comprehensive pre- and postoperative guidance;
  4. Access to hospitals with adequate infrastructure.

When to explore other erectile-dysfunction options

Consider alternatives if:

  • There is performance anxiety, depression or chronic stress;
  • Erectile issues follow abuse of alcohol, tobacco or illicit drugs;
  • Vacuum pumps or intra-urethral therapy have not yet been tried.

Book an appointment and clarify the best treatment for you

If you struggle with erections, schedule a consultation with an erectile-dysfunction specialist. This is the first step to uncover the causes and explore tailored solutions.
