What Is SizeGenetics?
SizeGenetics is a medical-grade traction device designed for non-surgical male enhancement. It uses gradual stretching to promote permanent tissue growth, backed by clinical studies.
How SizeGenetics Works
The device applies gentle tension to the penis over time, stimulating cytokinesis—a natural process where cells divide and multiply. This leads to permanent gains in length and girth without surgery.
- Traction method: Stretches tissues gradually, similar to how braces align teeth.
- Consistency matters: Daily use (3–6 hours) yields results, with cumulative hours determining progress.
- Permanent results: Gains remain after stopping use, unlike temporary pumps.
Ever wondered how traction therapy compares to quick-fix answers? While some methods offer instant but short-lived changes, SizeGenetics focuses on lasting improvement through controlled, science-backed tension.
Clinical data shows an average 28% increase in length and 19% in girth after 4–6 months. Plus, improved blood flow (up to 120%) supports stronger erections.
Curious if it’s right for you? Men use it for:
- Natural enlargement
- Correcting mild curvature (Peyronie’s)
- Improving sexual confidence
Always consult a doctor if you have severe curvature or scarring. The key is patience—consistent use delivers measurable, permanent changes.
What Is Bathmate?
Bathmate is a hydro penis pump that uses water pressure instead of air to create a vacuum around the penis. It promotes temporary enlargement, better blood flow, and improved erection quality.
How Bathmate Works
Bathmate relies on hydro-vacuum technology. You fill the device with warm water, place it over your penis, and create a seal against your body. Pumping out the water generates a vacuum, drawing blood into the erectile tissues for a firmer, fuller erection.
Each session lasts up to 5 minutes and can be repeated up to three times daily. Unlike traditional air pumps, Bathmate doesn’t require lubrication or constriction rings, making it a simpler option for some users. Since it’s used in the shower or bath, cleanup is straightforward.
The temporary results—like increased girth and stronger erections—come from enhanced blood flow. But, these effects fade over time, unlike permanent gains from traction-based devices. Have you ever wondered how consistent use affects long-term results? While Bathmate offers immediate benefits, it’s not designed for lasting tissue growth.
Key Differences Between SizeGenetics and Bathmate
Choosing between SizeGenetics and Bathmate depends on your goals—whether you want gradual, permanent gains or quick, temporary results. Here’s how they compare in design, ease of use, and safety.
Design and Mechanism
SizeGenetics is a penis extender that uses mechanical traction to stretch the penis over time. It works by gently pulling the tissue, which triggers cell growth for permanent length and girth gains. You’ll need to wear it daily for several hours to see results.
Bathmate is a water-based pump that creates a vacuum using hydro pressure. It draws blood into the penis for immediate girth and length expansion, but the effects fade after a few hours. It’s great for short-term enhancement before intimacy.
Ease of Use
With SizeGenetics, consistency is key. You’ll need to wear it 3–6 hours daily for months to achieve lasting results. It’s less convenient if you prefer quick fixes.
Bathmate is simpler—just 5-minute sessions, up to three times a day. You’ll see instant fullness, making it ideal for beginners or those who want fast results without long-term commitment.
Safety and Comfort
SizeGenetics is clinically tested and safe with proper use, but improper adjustment can cause discomfort. Its 58-way comfort system helps customize the fit for minimal irritation.
Bathmate is gentler on the skin since it uses water instead of air pressure. It’s less likely to cause bruising, but overuse may lead to temporary swelling. Always follow the recommended session times.
- SizeGenetics costs around $200 and takes 4–6 months for permanent gains.
- Bathmate is more affordable and works instantly, but results aren’t permanent.
