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.
