VED After Prostate Surgery: What the Evidence Says

VED After Prostate Surgery: What the Evidence Says

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

Ten months post-surgery. No natural erections. You've done everything your care team told you to do, and you're wondering whether anything is actually working. If that's where you are, this post is for you.

The question men ask most often at this stage isn't "what should I do?" Most men already have a protocol. The question is: "Does this actually work? And does it still matter if I've been waiting this long?"

There is a real answer to that question. The evidence for using a VED after prostate surgery is more specific than most men realize, and understanding the biology behind it can change the way you approach the months ahead. This post covers what the published clinical literature actually says about how and why vacuum erection devices are used in recovery after prostatectomy, what the evidence shows about outcomes, and why consistency over time matters more than most men expect.

Why VED Therapy Is Used After Prostate Surgery: The Biology of Nerve Recovery

Radical prostatectomy, whether robotic-assisted or open, involves working in close proximity to the cavernous nerves. These nerves run alongside the prostate and are responsible for triggering the vascular response that produces an erection. Even with a nerve-sparing approach, some degree of nerve disruption is common. The question after surgery isn't whether the nerves were spared in full; it's whether the tissue they supply stays healthy while those nerves recover.

This is where the published evidence becomes important. Per published literature, nerve recovery after prostatectomy is not instantaneous. It is a slow, months-long biological process. And during that window, the penile tissue that depends on a healthy blood supply is at risk of a specific problem: corporal hypoxia.

Studies on the physiology of penile oxygenation suggest that normal erections serve a biological maintenance function. Oxygenated blood delivered through the cavernous arteries supports the health of erectile tissue. Without that regular oxygenation, evidence suggests corporal tissue may become vulnerable to fibrotic changes over time. Per Padmanabhan and McCullough (Journal of Andrology, 2007), cavernous tissue oxygenation plays a role in the structural health of the erectile mechanism. These are mechanistic findings, and they remain an active area of clinical research, but they form the physiological rationale for why doing something proactive during recovery, rather than waiting, is the direction the clinical literature points.

A vacuum erection device operates by creating a low-pressure vacuum that draws blood into the penile tissue. Per published literature, this mechanical effect may support penile tissue health during the nerve recovery window. Research by Welliver et al. (Journal of Sexual Medicine, 2014) found, in a pilot study, that a brief VED application improved penile oxygen saturation in men after radical prostatectomy. These are early-stage findings, and individual outcomes vary, but they provide a mechanistic basis for VED use in recovery.

The goal of using a VED after prostate surgery during the recovery period is penile health (often referred to in published medical literature and studies as penile rehabilitation), which is the field's term for the structured effort to maintain tissue health while the nervous system recovers.

What Clinical Studies Actually Show About VED Use After Prostatectomy

Three studies in particular are cited repeatedly in the clinical literature on VED use after prostatectomy, and it is worth understanding what each one actually found.

Raina et al. (International Journal of Impotence Research, 2006) examined early vacuum constriction device use following radical prostatectomy. The study found that early VCD use was associated with facilitation of early sexual activity, maintenance of penile length and girth, and potentially earlier return of erectile function. The published finding language uses "facilitated" and "potentially," which is accurate: the literature has not established that VED use accelerates nerve recovery, and individual results vary significantly. But the direction of the findings supports early, consistent use as beneficial to the recovery process.

Dalkin and Christopher (International Journal of Impotence Research, 2007) studied early VED initiation beginning approximately one month after prostatectomy, with daily use over 90 days. Their findings on penile length preservation are notable: among men who used the device more than 50 percent of the days studied, only 3 percent experienced a stretched penile length decrease of 1 centimeter or more. This is a single-arm intervention study, and Tier B evidence, but it is one of the primary sources the 5th International Consultation on Sexual Medicine cited for length-preservation framing. The operative word in that finding is compliance. The men who used the device consistently saw markedly different results than those who did not.

Kohler et al. (BJU International, 2007) evaluated VED use during the nerve recovery window and found results consistent with the hypothesis that regular use may support penile tissue health and could potentially reduce cavernous fibrosis risk. This is an active area of clinical research, and the language must stay hedged: the published literature does not establish that VED use prevents cavernous fibrosis. What it supports is that consistent use during recovery may be protective, and that the mechanistic rationale is grounded in real physiology.

Taken together, these studies do not promise a specific outcome. What they support is a direction: early, consistent VED use during the recovery period is associated in published literature with better maintenance of tissue health, penile dimensions, and the conditions under which natural erections can return when nerve recovery has progressed sufficiently.

The 5th International Consultation on Sexual Medicine (Wang et al., Sexual Medicine Reviews, 2025) provides the most current consensus-level framing: VED therapy is a clinically recognized component of post-prostatectomy penile health, used alongside other approaches as part of a broader care continuum.

Does It Still Matter If You're Months Into Recovery?

This is the question that doesn't get answered often enough.

Per published literature, consistent VED use during recovery may support tissue health and functional recovery; studies suggest this is an area that continues to evolve in clinical research. The nerve recovery process after prostatectomy can take anywhere from several months to two years or more, and the evidence does not describe a moment after which VED use becomes irrelevant. Raina et al. (2006), Dalkin and Christopher (2007), and Kohler et al. (2007) collectively support early, consistent VED use as associated with better maintenance of tissue health and penile dimensions throughout the recovery window, not just the early weeks.

Qualitative research by Corbally et al. (International Journal of Nursing Studies Advances, 2026) noted that men who continued engagement with recovery approaches reported that the psychological experience of recovery does not follow the physiological timeline. Men frequently underestimate the degree of initial dysfunction, and later regret not having engaged more consistently with penile health approaches when they had the opportunity. The discouragement you may be feeling at 10 months is documented in the clinical literature. It is real, it is common, and it does not mean recovery is over.

What the evidence supports is this: the recovery window is longer than most men expect, and the penile tissue that needs to stay healthy for natural erections to return is still benefiting from regular oxygenation during that entire period. If you have been using a VED intermittently or stopped using it because results felt slow, the literature does not support stopping. It supports consistency.

The men in the Dalkin study who saw favorable outcomes were the ones who used the device on more than half the days in the study period. Compliance is the variable the research keeps returning to.

VED Therapy Within the Care Continuum: Where It Fits

A vacuum erection device is not a replacement for the full clinical conversation after prostatectomy. It is one component of a care approach that may also include medication, pelvic floor work, and regular follow-up with a urologist or sexual medicine specialist.

What distinguishes VED therapy in this context is that it is FDA-cleared as a Class II medical device for the treatment of erectile dysfunction, it requires no prescription, and it can be used consistently at home as part of a daily or near-daily routine. For many men, it is the most accessible and sustainable component of a recovery approach.

Per the 2025 literature review in the International Journal of Urological Nursing, VED use for erectile dysfunction recovery after radical prostatectomy is supported as a clinically recognized approach. The review reinforces what the earlier studies showed: the mechanism is physiologically grounded, the evidence is Tier B, and the clinical direction is toward consistent use beginning early in the recovery period.

For men who are months into recovery and have not yet experienced natural erections, the clinical literature does not suggest that the window has closed. It suggests that ongoing, consistent engagement with a structured approach, including VED therapy where appropriate, remains relevant to the recovery process.

A medical-grade vacuum erection device differs meaningfully from consumer-market alternatives. The Augusta Medical Systems SomaTherapy line is manufactured to ISO 13485 medical device quality standards and includes a safety feature that maintains vacuum within a therapeutic range. The design is built for daily therapeutic use, which is the type of use the clinical literature describes.

When to Talk to Your Physician

If you are more than six months post-prostatectomy and have not had a conversation with your urologist or sexual medicine specialist specifically about a recovery protocol, that conversation is worth having now. Published guidelines support discussing all available options, including VED therapy, with your care team.

Questions to bring to that conversation:

• Is VED therapy appropriate as part of my specific recovery protocol?
• Are there contraindications for me (anticoagulation therapy, bleeding disorders, or other conditions) that would affect device use?
• What combination of approaches does the evidence support for my situation?

The Augusta Medical Systems clinical support team is also available at 1-800-827-8382 to answer questions about device use and connect you with educational resources.

Frequently Asked Questions

How does a vacuum erection device support recovery after prostate surgery?
Per published literature, VED therapy may support penile tissue health during the nerve recovery period after prostatectomy by drawing oxygenated blood into erectile tissue. Studies including Welliver et al. (Journal of Sexual Medicine, 2014) found that brief VED application was associated with improved penile oxygen saturation after radical prostatectomy. This is a mechanistic finding that remains an active area of clinical research; individual outcomes vary and device use should be discussed with a physician.

Can I still benefit from VED therapy if it has been 10 or more months since my surgery?
Per published literature, the nerve recovery window after prostatectomy can extend one to two years or more, and studies including Raina et al. (2006), Dalkin and Christopher (2007), and Kohler et al. (2007) support consistent VED use throughout that window as associated with better maintenance of penile health. Qualitative research by Corbally et al. (International Journal of Nursing Studies Advances, 2026) also noted that men reported the psychological experience of recovery does not follow a strict physiological timeline, and that consistent engagement with a structured approach remains relevant throughout. This is educational content, not medical advice. Speak with your physician about your specific situation.

What does the published evidence say about penile length preservation after prostatectomy?
Dalkin and Christopher (International Journal of Impotence Research, 2007) found that among men who used a VED consistently (more than 50 percent of study days) starting approximately one month after surgery, only 3 percent experienced a stretched penile length decrease of 1 centimeter or more. This is a single-arm intervention study (Tier B evidence) and results vary by individual. The finding is cited in the 5th International Consultation on Sexual Medicine (Wang et al., Sexual Medicine Reviews, 2025) as primary support for length-preservation framing. Speak with your physician about whether early VED initiation is appropriate for your recovery.

How soon after prostate surgery can VED therapy begin?
The published literature, including Raina et al. (International Journal of Impotence Research, 2006), examined early initiation of VED use following radical prostatectomy. The timing of initiation should be determined by your treating physician based on your surgical outcome, catheter removal, and healing status. Augusta Medical Systems does not provide medical advice on initiation timing, and the clinical literature does not establish a single universally applicable starting point.

What is the difference between a medical-grade VED and a consumer device?
A medical-grade vacuum erection device is manufactured to medical quality standards (ISO 13485 in the case of Augusta Medical Systems products), includes engineered safety features such as a pressure-limiting mechanism, and is FDA-cleared as a Class II medical device for the treatment of erectile dysfunction. Consumer devices sold as novelty products are not subject to the same manufacturing requirements and are not FDA-cleared for therapeutic use. The clinical studies cited in penile health (often referred to in published medical literature and studies as penile rehabilitation) literature were conducted with medical-grade devices. This distinction matters for therapeutic use.

Penile Rehabilitation After Prostatectomy: Complete Guide

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.

Compare SomaTherapy models and find the right device for your situation

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.
