Ever wondered if non-surgical male enhancement actually works? You're not alone. Many men hesitate to explore answers because they doubt the science behind them. But what if there was a clinically tested method backed by research and medical endorsements?
That's where SizeGenetics (Official Store 🏅) clinical studies come in. Research shows its traction-based technology can lead to permanent results by stimulating natural tissue growth. Whether you're looking for increased size, better erection quality, or curvature correction, the evidence speaks for itself. Let’s jump into what the studies reveal—and why this could be the breakthrough you've been waiting for.
What Is SizeGenetics?
Page Contents
SizeGenetics is a medical-grade penile traction device designed for non-surgical male enhancement. Developed in Denmark, it uses clinically proven traction therapy to promote natural, permanent growth. Unlike temporary answers, it works by gently stretching the penis, triggering cell division and tissue expansion over time.

How Does It Work?
The device applies controlled tension, a method backed by research for increasing length and girth. Studies show an average 28% increase in length and 19% in girth after 4–6 months of consistent use. It also improves blood flow by up to 120%, improving erection quality.
Who Is It For?
- Men seeking permanent enlargement without surgery.
- Those with Peyronie’s Disease looking for curvature correction.
- Anyone wanting stronger erections through improved blood flow.
Results last even after stopping use, making it a long-term solution. Curious how it compares to other methods? Let’s dive deeper.
Overview of the SizeGenetics Clinical Study
Clinical studies support the effectiveness of penile traction devices like SizeGenetics for length gains and curvature correction. Research shows consistent use leads to measurable improvements, making it a non-surgical option for men seeking enhancement.
Study Design and Methodology
A study published in the British Journal of Urology tested penile extenders over six months. Participants wore the device for about five hours daily, tracking changes in length, curvature, and sexual function. Researchers used patient logs, photos, and clinical measurements to verify results. The findings showed an average increase of 1–2 cm in length and noticeable improvements in Peyronie’s-related curvature.
Participant Demographics
Studies included men aged 20–70, with most users between 30 and 50. Participants had varying baseline lengths and curvatures, representing a broad range of potential users. The treatment was well-tolerated, with minimal side effects, making it accessible for long-term use.
Key Findings of the SizeGenetics Clinical Study
Clinical studies confirm that penile traction devices like SizeGenetics deliver measurable results when used consistently. Let’s break down the evidence on effectiveness and safety.
Effectiveness and Results
Research shows daily use of traction devices increases penile length by approximately 0.67 inches over six months. A University of Turin review of 10 studies involving 109 men supported these findings, with some users reporting gains exceeding 1 inch. The British Journal of Urology published a study where participants wore the device for six months, showing improvements in both length and curvature, especially for men with Peyronie’s disease.
Key takeaways:
- Gradual progress: Longer use (up to 12 months) yields better results.
- Dual benefits: Users see enhancements in erectile function and straightening of curvature.
- Permanent changes: Gains persist even after stopping use.
Safety and Side Effects
Serious side effects are rare when following guidelines. Most men experience only mild discomfort or slight bruising during the initial adjustment period. Clinical trials involving daily use for up to 8 hours reported no important adverse events.
What to expect:
- Temporary sensitivity: Discomfort typically fades within days.
- Low risk: Studies deem traction therapy safe for Peyronie’s and erectile dysfunction.
- User-dependent: Proper usage minimizes risks.
Curious how these findings compare to other methods? Let’s explore further.
Comparing SizeGenetics to Other Solutions
When exploring penile traction devices, you’ll find many options claiming similar benefits. SizeGenetics stands out due to its FDA clearance and ergonomic design, which enhance comfort and effectiveness. Unlike generic extenders, it’s backed by clinical studies showing measurable results—like a 28% increase in length and 19% in girth over 4–6 months.
Key Differences
- Medical-Grade Quality: SizeGenetics is developed in Denmark and tested for safety, while some competitors lack rigorous clinical validation.
- Permanent Results: Gains from SizeGenetics persist after stopping use, whereas pumps or supplements often provide temporary effects.
- Peyronie’s Disease Treatment: It’s proven to reduce curvature, a feature not all extenders offer.
Why Traction Beads Alternatives?
Devices like pumps or pills might seem easier, but they rarely deliver lasting changes. Traction therapy works by stimulating natural tissue growth, not just forcing blood flow. Think of it like stretching a muscle—consistent tension leads to real, gradual expansion.

Cost vs. Value
Generic extenders may cost less upfront, but their flimsy builds often lead to replacements. SizeGenetics’ durable design and money-back guarantee make it a smarter long-term investment.

User Testimonials and Feedback
Users of penile traction therapy often share their experiences to highlight real-industry results. Many report noticeable improvements in length, girth, and curvature after consistent use.
- Length gains: Some users mention achieving an increase of 0.5–1 inch within 4–6 months. One individual noted a 32% improvement in flaccid length after daily use.
- Curvature correction: Those with Peyronie’s disease describe reduced bending and better symmetry over time. Anecdotal feedback aligns with clinical findings showing important curvature improvement.
- Erection quality: Several users report stronger, more reliable erections due to enhanced blood flow.
Have you wondered if these results are typical? While individual outcomes vary, the consistency in feedback suggests traction therapy delivers measurable benefits. Users emphasize patience and adherence to the recommended usage schedule for optimal results.
Comfort and ease of use also come up frequently. Many appreciate the adjustable design, which allows for gradual tension increases without discomfort. A few note initial adjustments but highlight improved tolerance within weeks.
