How to Improve Erections After Prostate Surgery: What the Evidence Says

Erectile dysfunction after prostate surgery is common, underdiagnosed, and undertreated — but not inevitable. With the right rehabilitation protocol started at the right time, many men recover meaningful erectile function. This guide covers what the evidence actually shows, what approaches work, and how pelvic floor rehabilitation fits into the recovery process.

Why Prostate Surgery Affects Erectile Function

The nerves responsible for erections run directly alongside the prostate gland. During prostatectomy (surgical removal of the prostate), these neurovascular bundles are inevitably stressed and sometimes damaged, even in nerve-sparing procedures.

The result: immediately after surgery, most men experience some degree of erectile dysfunction. The key word is immediately — because for many men, function returns. The timeline and degree of recovery depend on several factors: the surgical technique used, whether nerve-sparing was performed, the patient's age, baseline erectile function before surgery, and — critically — how aggressively rehabilitation is pursued.

The Penile Rehabilitation Window

Research has established a concept called penile rehabilitation — the idea that the penis, like any other organ, requires oxygenation and activity to maintain healthy tissue during nerve recovery. Months of disuse lead to structural changes (fibrosis, smooth muscle loss) that make recovery harder even after nerves regenerate.

The window matters: rehabilitation started within the first 3–6 months post-surgery produces significantly better outcomes than rehabilitation started later. This is why urologists increasingly recommend proactive intervention — not waiting to "see what comes back."

Pelvic Floor Rehabilitation and Erections

The connection between the pelvic floor and erections is direct and well-documented. The bulbocavernosus and ischiocavernosus muscles — part of the pelvic floor — play an active role in maintaining erection rigidity and controlling ejaculation. When the pelvic floor is weak or poorly coordinated post-surgery, erectile function is further compromised.

Multiple studies show that pelvic floor rehabilitation significantly improves erectile function recovery after prostatectomy. Men who perform structured pelvic floor exercises post-surgery recover continence faster and report better erectile outcomes than those who do not.

Evidence-Based Approaches to Improve Erections Post-Surgery

1. Pelvic Floor Rehabilitation (Start Within 4 Weeks)

Begin as soon as medically cleared — usually within 2–4 weeks post-surgery. Focus on slow contractions with full relaxation, progressing to functional exercises as strength returns. Consistency over months is what drives results, not intensity in any single session.

2. PDE5 Inhibitors (Viagra, Cialis)

Phosphodiesterase type 5 inhibitors are the most evidence-supported pharmacological approach to penile rehabilitation. Low-dose daily tadalafil (Cialis) in particular has shown benefits for preserving penile tissue health and improving erection recovery rates. Discuss timing and dosing with your urologist.

3. Vacuum Erection Devices

Vacuum erection devices (VEDs) draw blood into the penis, creating an erection-like state that oxygenates penile tissue. Used regularly — typically once daily for 5–10 minutes — they help prevent fibrotic changes during the nerve recovery period. Most guidelines recommend starting VED use within 4–8 weeks post-surgery.

4. Penile Injections (Alprostadil)

Injectable alprostadil produces reliable erections regardless of nerve status by directly dilating blood vessels. Useful for maintaining sexual activity and penile health during the recovery period, or as a longer-term solution if nerve recovery is incomplete.

5. Psychological and Partner Support

Post-surgical erectile dysfunction has a significant psychological component. Performance anxiety, loss of confidence, and relationship strain compound the physical challenge. Sex therapy and partner communication are underutilized but effective parts of a complete rehabilitation plan.

Managing Urinary Leakage During Sex

Many men post-prostatectomy experience climacturia — leakage of urine at orgasm — or general leakage during sexual activity. This is often more distressing than erectile dysfunction itself and causes many men to avoid sexual activity altogether.

Pelvic floor rehabilitation specifically addresses climacturia by strengthening the sphincter control that was disrupted during surgery. While rehabilitation proceeds, Orykas absorbent underwear provides discreet protection during daily life, allowing men to feel confident and resume normal activity.

A Realistic Timeline

Recovery after nerve-sparing prostatectomy in a younger, healthy man with good baseline function can occur within 12–18 months. For older men or those with bilateral nerve involvement, the timeline may extend to 24 months, and some degree of medical support may be permanently beneficial. Regardless of where on this spectrum you fall, early, consistent rehabilitation always improves the outcome.

Track your progress — both urinary and erectile — with a structured tool. Keel's daily tracking lets you monitor improvements over time, which is important both for motivation and for informed conversations with your care team.

Talking to Your Urologist

Be direct with your care team about erectile recovery — it's a legitimate medical concern, not a cosmetic one. Ask specifically about: nerve-sparing technique outcomes, recommended timeline for PDE5 inhibitors, VED protocol, and referral to a pelvic floor physiotherapist or a programme like Keel.
