Penile Rehabilitation After Prostatectomy: Complete Guide

The conversation your surgeon had with you before the operation was likely focused on cancer. That makes sense. But for many men, the question that keeps them up at night in the weeks after surgery is a different one: will I get my sexual function back?

You are not alone in asking it. Erectile dysfunction (ED) after prostatectomy is one of the most common and emotionally difficult side effects of prostate cancer treatment. And yet, it is also one of the most under-discussed. Many men leave the hospital without a clear plan for what comes next.

This is educational content. It is not medical advice. Consult your physician.

This guide is designed to fill that gap. We will walk through why ED happens after prostate surgery, what penile rehabilitation after prostatectomy involves, and how vacuum erection therapy fits into a structured recovery plan. The founders of Augusta Medical Systems have been working in this space for over 40 years. Their mission has always been the same: no man should be told to simply enjoy the time he has left.

Why Penile Rehabilitation After Prostatectomy Matters

Prostatectomy removes the prostate gland. Even in nerve-sparing procedures, the cavernous nerves that control erections run very close to the prostate. They are often stretched, compressed, or disrupted during surgery. This is not a failure of your surgeon. It is anatomy.

After surgery, those nerves need time to recover. This process is called neuropraxia, and it can take anywhere from six months to two years. During that window, the nerves are not sending the signals that allow blood to flow into the penis and create an erection.

Here is why that matters beyond the immediate impact on sexual function: without regular oxygenated blood flow, the smooth muscle tissue inside the penis can lose elasticity over time. Some published literature suggests this may contribute to changes in penile tissue health, including increased risk of cavernous fibrosis, though this remains an active area of clinical research (Kohler et al., BJU International, 2007).

Penile rehabilitation is the clinical term for a structured approach to maintaining penile tissue health and supporting erectile function recovery during this nerve recovery window. It is not a cure. It is a proactive strategy, one that your care team should be helping you plan.

What is a vacuum erection device and how does it work?

What Penile Rehabilitation After Prostatectomy Typically Includes

Rehabilitation protocols vary by physician and institution. Most incorporate some combination of the following:

PDE5 inhibitors (oral medications). Drugs like sildenafil or tadalafil are often prescribed in low daily doses during recovery. Their purpose in this context is less about producing erections on demand and more about maintaining blood flow to penile tissue. Montorsi et al. established an early foundation for pharmaceutical intervention in this space, documenting benefits from proactive treatment in the post-surgical period.

Vacuum erection devices (VEDs). A vacuum erection device creates negative pressure around the penis, drawing blood into the corpora cavernosa. When used regularly, even without the goal of sexual activity, this mechanical stimulation may support oxygenated blood flow to penile tissue during the recovery period, consistent with published literature on the subject.

Intracavernosal injections. Some men are prescribed injectable medications to produce erections directly. These can be effective but carry a higher barrier to compliance compared to other options.

Penile implant consultation. For men who do not recover spontaneous function after two or more years, a penile implant is a surgical option. Most physicians prefer to exhaust conservative approaches first.

The most important word in penile rehabilitation is "proactive." Waiting to see what happens and addressing ED only if it persists is a common approach, but the evidence base increasingly supports early intervention as more beneficial to long-term outcomes (Raina et al., 2006).

How Vacuum Erection Therapy Supports Recovery

Vacuum erection therapy is among the oldest and most studied forms of ED treatment. It is FDA-cleared for the treatment of erectile dysfunction. The mechanism is straightforward: a cylinder is placed over the penis, a pump creates negative pressure, and blood is drawn into the erectile tissue. A constriction ring holds that engorgement in place for sexual activity.

In the context of penile rehabilitation after prostatectomy, the device is often used differently than it would be for situational ED. Many physicians recommend daily or near-daily use during the nerve recovery window, with or without the constriction ring, simply to promote regular blood flow to the tissue.

Raina et al. (2006) documented favorable adherence with vacuum erection devices compared to injection therapy in post-surgical settings, an important consideration given that a rehabilitation protocol only works if a man actually follows it.

Augusta Medical Systems manufactures the SomaTherapy line of vacuum erection devices. These are medical-grade devices, not the lower-quality products sold in general retail. The SomaTherapy OTC Manual is the most widely recommended entry point for men beginning a rehabilitation protocol. The SomaErect STF and STF Plus models offer anatomically customized cylinder sizing for men who require a more precise fit.

Important precautions: Vacuum erection therapy is not appropriate for all men. Men taking anticoagulant medications or with severe bleeding disorders should consult their physician before using a VED. Men with autonomic neuropathy or certain vascular conditions may require physician-supervised screening before starting therapy. Always discuss your complete medical history with your care team before beginning any rehabilitation protocol.

Talking to Your Doctor: Starting the Conversation

Many men do not bring up sexual function concerns with their physicians. The reasons are understandable: the visit is focused on cancer surveillance, the topic feels embarrassing, or they assume nothing can be done.

None of those reasons should stop you from asking.

Your urologist or primary care physician can help you:

  • Assess where you are in the recovery timeline
  • Determine whether you are a candidate for a structured rehabilitation protocol
  • Discuss pharmaceutical options, vacuum therapy, or a combination approach
  • Set realistic expectations for recovery

If your physician does not bring it up, you can. A simple statement works: "I'm concerned about my erectile function since the surgery. Can we talk about what options I have?"

You deserve that conversation. And the research suggests that having it early, rather than waiting, gives you a better chance at meaningful recovery.

What the Evidence Says About Timing

The 5th International Consultation on Sexual Medicine (2025) reviewed the published evidence on vacuum erection therapy after radical prostatectomy. Two findings are worth understanding before you start a rehabilitation protocol.

First, on nerve recovery. The ICSM panel concluded that vacuum erection therapy has not been shown to accelerate the return of spontaneous erectile function after prostatectomy. Nerve recovery has its own biological timeline — typically six months to two years — and no current rehabilitation tool reliably speeds it up. This is important to know so you can set realistic expectations with your care team.

Second, on tissue and length preservation. Here the evidence is stronger and more actionable. Penile length loss is common after prostatectomy. The ICSM review found that men who began vacuum erection therapy approximately one month after surgery experienced significantly less length loss than men who waited until six months. In one comparison, 12% of early initiators lost two centimeters or more of length, versus 45% of late initiators. Among men who used the device consistently — more than half the days during the rehabilitation period — only 3% experienced one centimeter or more of length loss.

What this means in practice. Talk with your urologist about starting a vacuum therapy protocol earlier rather than later in the recovery window, and about what consistent daily use looks like for your situation. A common protocol described in the literature involves brief cycles of erection and release, repeated for ten to fifteen minutes daily. Your physician will tell you what is appropriate for your case.

If you are past the twelve-month mark without the recovery you hoped for, you have not missed your window. Speak with your urologist about additional options, including continued rehabilitation and other FDA-cleared therapies.

Frequently Asked Questions

How does penile rehabilitation after prostatectomy actually work?
Penile rehabilitation uses structured, proactive steps during the nerve recovery window after prostate surgery to support erectile tissue health and encourage blood flow. It may include oral medications, vacuum erection devices, or a combination. The goal is to protect penile tissue and support recovery of nerve function before permanent changes occur.

Can a vacuum erection device help with ED after prostate surgery?
Yes. FDA-cleared vacuum erection devices are used by many men as part of a penile rehabilitation protocol after prostatectomy. They work by mechanically drawing blood into the erectile tissue, which may support oxygenated blood flow during recovery. Your physician can advise whether a VED is appropriate for your situation.

When should I start penile rehabilitation after my prostatectomy?
Most physicians recommend beginning a rehabilitation protocol within the first few weeks after surgery, once initial healing has progressed. Early intervention is associated with better outcomes in the published literature. Ask your surgeon or urologist at your first post-operative visit.

Is penile rehabilitation after prostatectomy covered by insurance?
Augusta Medical Systems has operated on a cash-pay basis since 2015. We do not process insurance claims. Contact our team directly for current pricing and options.
