What is a Penile Prosthesis and How Does It Work?

Erectile dysfunction is a common problem that affects the quality of life for many men. A penile prosthesis is a surgical solution used when other treatment methods have failed. This device, implanted inside the penis, helps achieve an erection and restores sexual function.

Types of Penile Prostheses

• Malleable (semi-rigid) prostheses: Always firm but can be manually positioned when needed.

• Inflatable prostheses: Inflated with a pump when an erection is desired and deflated after use.

Advantages of Penile Prostheses and Permanent Solution for Erectile Dysfunction
Penile prostheses are often the last resort when medications and other treatments are insufficient. They provide a natural and controlled erection. Clinical studies report patient and partner satisfaction rates around 90–95%.

Preoperative and Postoperative Process

Before Surgery:

• Evaluation with blood tests and Doppler ultrasound

• Diabetes control

• Infection prevention measures

After Surgery:

• Care to prevent infections

• Avoid sexual activity for approximately 1 month

• Recovery usually takes around 1 month

Types of Penile Prostheses

• Single-piece bendable prostheses: Easy to use, always firm, can be bent for storage.

• Two-piece inflatable prostheses: Closer to natural function, patient controls erection as desired.

• Three-piece inflatable prostheses: Most natural appearance and function, high patient satisfaction.

Who is a Candidate for a Penile Prosthesis?

• Men with erectile dysfunction unresponsive to other treatments

• Patients after prostate cancer surgery

• Advanced diabetes patients

• Patients with severe cardiovascular disease

• Those who have experienced pelvic trauma

• Patients with Peyronie’s disease or significant penile curvature

How is Penile Prosthesis Surgery Performed?

• General or regional anesthesia

• Prosthesis inserted through a small incision at the base of the penis

• Procedure duration: 45 minutes to 1.5 hours

• Hospital stay: 2–5 days

• Avoid sexual activity for 4–6 weeks postoperatively

Risks and Complications

• Infection risk (3–5%), prevented with antibiotics

• Mechanical failures

• Rare injuries to the penis or urethra

• Prosthesis may need removal over time

Lifespan and Maintenance of Penile Prostheses
Penile prostheses generally maintain functionality for around 10 years. Regular check-ups and care can extend their lifespan.

Patient and Partner Satisfaction
High satisfaction improves self-confidence and enhances sexual life quality.

Sexual Life After Penile Prosthesis Surgery
Sexual activity usually resumes within 4–6 weeks. The patient can control the erection as desired, allowing for long-lasting sexual activity.
