By OmniFlow TeamPeyronie's disease (a condition in which scar tissue forms inside the penis, causing curvature, pain, or shortening) can be distressing both physically and emotionally. While surgery and injectable medications are well-known treatment paths, many men look for non-invasive options first. One device that comes up often in this search is the vacuum erection device (VED), more commonly known as a "penis pump."
Originally designed to treat erectile dysfunction (ED), VEDs have gained attention as a possible tool for managing Peyronie's disease, particularly in its early, "active" phase. This article explains how VEDs work, what the current evidence says about their effectiveness for Peyronie's disease, how they compare to other treatments, and what to know before trying one.
What Is a Vacuum Erection Device?
A vacuum erection device consists of three basic parts: a plastic cylinder that fits over the penis, a pump (manual or battery-powered) that removes air from the cylinder, and a constriction ring placed at the base of the penis. As air is drawn out of the cylinder, negative pressure pulls blood into the penile tissue, producing an erection. The ring is then used to help maintain that erection after the cylinder is removed.
VEDs have been an FDA-cleared treatment for erectile dysfunction for decades. More recently, researchers and clinicians have explored whether the mechanical stretching and increased blood flow VEDs produce might also benefit men with Peyronie's disease — independent of their use for ED.
How VED Therapy Is Thought to Help with Peyronie's Disease
The theory behind using a VED for Peyronie's disease centers on two mechanisms:
Mechanical Stretching
The negative pressure applied during use stretches the tunica albuginea, the fibrous sheath surrounding the erectile chambers where Peyronie's plaques form. Over time, this stretching may help reduce curvature and counteract the tissue contraction caused by scarring.
Improved Blood Flow
Regular use may increase oxygenation and circulation to penile tissue, which some researchers believe could support tissue health and reduce fibrosis (scar tissue buildup) during the active phase of the disease.
Peyronie's disease typically progresses through two phases: an acute phase, marked by active inflammation, pain, and changing curvature (usually lasting 6–18 months), and a chronic or stable phase, when curvature has stopped progressing and pain has resolved. Most research on VEDs for Peyronie's disease focuses on the acute phase, when tissue is still responsive to treatment, or as a rehabilitative tool after surgery.
What the Evidence Says
Clinical research on VEDs specifically for Peyronie's disease is still limited compared to studies on penile traction devices or injectable therapies, but several small studies have reported encouraging findings:
- Some trials have found modest reductions in penile curvature and improvements in stretched penile length among men who used a VED regularly.
- VED use has also been studied as part of post-surgical rehabilitation, helping restore length and rigidity after procedures like plaque incision or grafting.
That said, most available studies involve small sample sizes and varying protocols, so results aren't as robust or standardized as those for dedicated penile traction therapy (PTT) devices, which are specifically engineered to apply constant, controlled stretch over many hours per day.
To put it simply, researchers generally view VEDs as a complementary or adjunct therapy rather than a first-line, standalone treatment for correcting significant curvature.
VED vs. Other Peyronie's Disease Treatments
| Treatment | How It Works | Invasiveness | Best For |
|---|---|---|---|
| Vacuum erection device (VED) | Mechanical stretch + increased blood flow | Non-invasive | Mild curvature, acute phase, post-surgical rehab, co-occurring ED |
| Penile traction therapy (PTT) | Sustained mechanical stretching device worn for hours daily | Non-invasive | Acute or stable phase, reducing curvature and preserving length |
| Oral/topical medications | Varies (e.g., anti-inflammatory or antioxidant support); limited standalone evidence | Non-invasive | Adjunct use; not typically effective alone |
| Collagenase clostridium histolyticum (CCH) injections | Enzyme breaks down collagen in the plaque | Minimally invasive | Moderate curvature with a palpable plaque |
| Surgery (plication, incision/grafting, implant) | Physically corrects curvature or replaces erectile tissue | Invasive | Severe, stable curvature or significant erectile dysfunction |
VEDs are sometimes used alongside other treatments (for example, combined with traction therapy or as part of a recovery plan after CCH injections or surgery) rather than as a sole intervention.
How VED Therapy Is Typically Used
Protocols vary by study and by individual clinical guidance, but general patterns reported in the literature include:
- Short daily sessions, often in the range of several minutes at a time, performed most days of the week
- Use without the constriction ring in some Peyronie's-specific protocols, since the goal is tissue stretching rather than maintaining an erection for intercourse
- Programs that run for several weeks to a few months, with progress monitored by a clinician
Because protocols differ and improper use can cause tissue injury, anyone considering VED therapy for Peyronie's disease should start under the guidance of a urologist rather than following generic instructions meant for ED treatment.
Potential Risks and Side Effects
VEDs are generally considered low-risk, but side effects can include:
- Temporary bruising or petechiae (small red or purple spots from broken capillaries)
- Numbness or tingling in the penis
- Discomfort or pain, especially with excessive pressure or duration
- Reduced sensation with overly frequent or aggressive use
Men with bleeding disorders (or those taking blood-thinning medications) should discuss VED use with their doctor first, as they may face a higher risk of bruising or bleeding. A device with a pressure-release valve or pressure gauge is generally recommended to avoid applying excessive vacuum force.
Who Is a Good Candidate?
VED therapy tends to be most useful for men who:
- Are in the acute phase of Peyronie's disease
- Have mild to moderate curvature without significant plaque calcification
- Also experience erectile dysfunction alongside Peyronie's disease
- Are recovering from Peyronie's-related surgery and need help restoring length and function
Men with severe curvature, hinge deformities, or heavily calcified plaques are less likely to see meaningful improvement from a VED alone and may be better candidates for traction therapy, injections, or surgical correction.
When to See a Urologist
It's worth scheduling an evaluation with a urologist — ideally one experienced in Peyronie's disease — if you notice:
- New or worsening penile curvature
- Persistent pain during erections
- A lump or band of tissue that can be felt under the skin
- Erectile dysfunction that coincides with these symptoms
A urologist can confirm the diagnosis, assess the phase and severity of the disease, and help build a treatment plan tailored to your specific situation.
