The complete at-home system for men correcting penile curvature and Peyronie's disease. The SizeGenetics Penile Curvature & Peyronie's Edition is an FDA-registered medical traction device that applies gentle, measured, directional tension to gradually straighten penile curvature — non-surgically, privately, at home.
Built on the SizeGenetics traction platform trusted by men for over 25 years, this edition ships with the full elongation-bar range and comfort accessories for the long, repeatable daily sessions curvature correction requires.
What penile curvature and Peyronie's actually are
Peyronie's disease is the formation of fibrous scar tissue (plaque) within the tunica albuginea, the elastic sheath surrounding the erectile chambers. That plaque is less elastic than healthy tissue, so the penis bends toward it during erection. Congenital curvature is similar in effect without the plaque. Both respond to sustained mechanical tension.
How traction therapy corrects curvature
Penile traction therapy applies a steady, comfortable stretch along the shaft. Sustained tension triggers mechanotransduction — the process by which cells convert mechanical load into biological remodeling. Chung & Brock (Therapeutic Advances in Urology, 2013) documented that mechanical traction drives "reorganization and remodelling of collagen fibres into uniform densely packed fibrils parallel to the axis of mechanical strain." The European Association of Urology (EAU) Guidelines on Penile Curvature (2023) recognise penile traction therapy as a conservative, non-surgical treatment option for Peyronie's disease — addressing both curvature and length.
Across 15+ peer-reviewed studies (1,000+ patients), penile traction therapy shows a ~27% mean curvature improvement:
- Levine et al. (Journal of Sexual Medicine, 2008) — pilot study, 10 Peyronie's patients, 2–8 hours/day for 6 months: 10°–45° curvature reduction (avg ~33%) plus 1.0–2.5 cm length gain. [ref]
- Gontero et al. (Journal of Sexual Medicine, 2009) — Phase II prospective study, 15 patients, 4–6 hours/day for 6 months; gains remained stable after the device was discontinued. [ref]
- Moncada et al. (BJU International, 2019) — controlled multicentre study, 93 patients across six university hospitals (47 treatment / 46 control): treatment group achieved a mean 31.2° curvature reduction (41.1% improvement) and 1.8 cm length gain over 12 weeks. [ref]
Typical timeline: measurable curvature reduction of 10–20° by months 3–6, building to 15–30° by months 6–9 with consistent wear.
Most patients notice initial curvature improvement within 3–6 months of consistent daily wear. Curvature exceeding 90°, or active/painful (acute-phase) Peyronie's, warrants urological evaluation before traction.
Why men choose this edition

Frequently asked questions
How long until I see curvature improvement? Traction therapy is gradual. Published studies used 2–8 hours of daily wear over roughly 6 months (Levine 2008; Gontero 2009). Most men notice initial curvature improvement within 3–6 months of consistent daily use.
What degree of curvature can be treated at home? Mild-to-moderate curvature responds best to conservative traction; severe curvature or curvature with pain warrants a urologist's assessment first.
Traction vs surgery — which is right for me? Traction is non-invasive, reversible and low-risk but slower; surgery is faster but invasive with its own risks. Many men trial conservative traction before considering surgery.
Is it safe / does it hurt? Worn correctly at recommended tension it should feel like a firm stretch, not pain. Start low and build up. Stop and consult a professional if you experience pain, numbness or discoloration.
Can I use it for general straightening without Peyronie's? Yes — congenital curvature responds to the same directional traction.
