Using a Penis Pump for Peyronie’s - How to See Results

Peyronie’s disease (the technical term for "bent penis") is a challenging condition characterised by scar tissue (plaques) forming inside the penis, leading to curvature, pain, and erectile dysfunction in up to 10 percent of men. Alongside physical symptoms, many men experience significant psychological impact such as stress or reduced self-esteem. Treatment options for Peyronie's disease include things like focused shockwave therapy or surgery, but one non-invasive therapy that fosters suprisingly good results is vacuum erection devices (commonly known as penis pumps or VEDs).

Why a Penis Pump May Help

Vacuum erection devices generate negative pressure around the penis, drawing blood into erectile tissue. This can temporarily straighten the bend in the penis and gently stretch scarred or fibrotic areas over time. VEDs offer a low-risk, at-home therapeutic option without the need for surgery or injections.

Clinical Evidence

• MacDonald et al. (2020): A clinical study found that men using a VED experienced significant curvature reductions. Those untreated often worsened. Baseline severity correlated with improvement, and untreated participants saw declines in sexual function. (Sources include ProactivePH and patient support websites.)
• Khayyamfar et al. (2021): In 200 men in the acute phase of Peyronie’s, a protocol using three differently shaped vacuum cylinders, applied for 30 minutes three times daily over three months, led to curvature reduction (from approximately 52° to 32°), plaque size decrease (from around 1.2 cm to 0.74 cm), and improved erectile function and pain.

• Progressive “inner tube” protocol (Ghasemlouei 2020): A vacuum therapy protocol using progressively larger multi-diameter cylinders (inner tubes) over three months reported improvements in curvature, plaque size, and plaque number, with many men satisfied and not requiring further treatment. The key feature is starting narrow and progressing to wider tubes over time, while keeping pressure controlled and consistent. (See the protocol summary on this page.)
• Urology News (single-arm study): A 12-week regimen of VED use twice daily for ten minutes without a constriction ring delivered penile length increases of 0.5–1.5 cm and curvature improvement by 5–25°. (Urology News)
• Lin et al. (2017) – Animal model: In a rat model of Peyronie’s disease, VED and traction devices both significantly reduced curvature in comparison to controls. VED usage also preserved smooth muscle integrity and reduced fibrosis markers such as TGF-β1. (Seminars in Male Reproductive Health)
• Pre- and post-operative VED use (MDPI study): Patients who used VED three times weekly for three months before surgery and one month after saw 94.7 percent complete curvature correction, a 1.5 cm increase in penile length, no hourglass deformities, and high satisfaction scores.

Protocol Recommendations for Effective Use

Main suggested protocol: the Progressive “Inner Tube” Protocol

This approach is widely used in conservative UK pathways because it applies controlled longitudinal stretch by using progressive inner tubes, sometimes called Peyronie's tubes (starting smaller, then moving up in diameter as tolerance improves).

1. Frequency: Pump up to 3 times daily.
2. Session length: Aim for 30 minutes per session (this is typically broken into manageable cycles rather than continuous suction).
3. Progression: Begin with the smallest inner tube (narrowest diameter) and progress to wider tubes over time as comfort and seal improve.
4. Timeframe: Commit to weeks to months; many protocols describe a 3-month course for meaningful structural change.
5. Intensity: Use controlled, gentle vacuum. You should feel stretch/pressure, not sharp pain.
6. Stop rules: Do not use painfully, and stop if you notice significant bruising or worsening curvature. Seek clinician advice if unsure.

• Use a medical-grade VED designed for therapeutic use, ideally with good pressure control and compatible progressive tube options.
• If you are in the acute phase and supervised by a clinician, intensive multi-cylinder protocols (e.g., Khayyamfar et al.) may be used, but for most home users the progressive inner tube approach is a practical primary protocol.
• For patients preparing for surgery, begin VED therapy three months in advance and resume one month post-operatively to optimise outcomes.
• Consistency is critical. Evidence and clinical practice both suggest the best results emerge after sustained use over 8–12 weeks (or longer).
• VED therapy is often most effective when combined with other conservative options (for example, clinician-directed traction, pharmacotherapy, or targeted rehabilitation).

Mechanism of Action

VEDs exert controlled negative pressure to stretch the penile tissue, encouraging increased blood flow and oxygenation. Mechanotransduction may remodel the collagen structure in fibrotic plaques. Animal studies show VED use is linked to reduced TGF-β1 expression and improved smooth muscle preservation—factors critical in reversing Peyronie’s-related fibrosis.

Safety Considerations

• Always use a clinically approved, medical-grade VED—not high-pressure “enhancement” products that may risk tissue damage.
• Constrictive rings are generally not advised in Peyronie’s treatment unless specifically prescribed by a clinician; they can increase injury risk.
• When used correctly and within recommended pressure limits, VEDs have a strong safety record with rare adverse events.
• Vacuum therapy is generally considered most suitable for mild to moderate curvature and stable disease; severe curvature, significant pain, or complex deformities warrant specialist input.

Summary Table

What is the Best Penis Pump for Peyronie's?

The best penis pump to see lasting results depends on whether or not you are also suffering from erectile function issues (ED). Some pumps come with a constriction ring that can be used to keep the blood in the penis once an erection is achieved. Others, called Penile Vacuum Trainers, just vacuum blood into the penis to train it straight.
