In 2025, three of the top penis straightening devices are the Quick Extender Pro, Phallosan Forte, and Penimaster Pro. This article will explore how these devices work, their effectiveness for penile curvature, and their pros and cons, while also diving into other methods like jelqing to improve penile alignment and health.

Peyronie's disease, a condition that causes penile curvature, can impact a man’s confidence and sexual performance. Fortunately, medical devices known as penis traction devices, or extenders, have gained popularity for their ability to correct penile curvature and assist in treating conditions like Peyronie's disease.

#1. Quick Extender Pro ($179)

How Does It Work?

The Quick Extender Pro is a leading penis traction device that works by applying gentle, controlled traction to the penis. This device consists of an adjustable, strap-like mechanism that attaches to the base of the penis and exerts a gradual pulling force, promoting tissue expansion over time.

The device helps correct penile curvature by encouraging the body to create new, healthier tissue along the stretched areas, thereby realigning the penile structure. The continuous pulling force stretches both the straight and curved parts of the penis, leading to an overall straighter shape over time.

How It Helps to Fix Penis Curvature (Peyronie’s Disease)

The consistent traction provided by the Quick Extender Pro stimulates cell division and tissue regeneration, which helps to gradually stretch and straighten the fibrous plaques responsible for the penile curvature in Peyronie’s disease.

By applying gentle pressure to the affected areas, the device promotes the breakdown of scar tissue while encouraging the growth of new, more flexible tissue, which can straighten the penis over time.

In addition, studies indicate that traction therapy can increase penile length by 1 to 2 inches in many users.

Effective for Peyronie’s disease: Clinically proven to reduce curvature by up to 40%.

Double Strap Support (DSS): Patented design offers extra comfort during extended use.

Penis enlargement: Simultaneously helps to increase penile length and girth.

Non-invasive: Offers a natural alternative to surgery.

Time commitment: Requires consistent daily use for several hours.

Initial discomfort: Some users may experience slight discomfort during the first few days of use.

Cost: Can be expensive compared to other penis straightening methods.

Adjust the device to fit the length of your flaccid penis.

Secure the base ring around the penis and place the adjustable rods along the sides of the shaft.

Gently tighten the device to create a small amount of traction.

Wear the device for 4 to 6 hours a day for optimal results.

The Quick Extender Pro comes in various packages ranging from $129 to $349, depending on the version you choose (Value Edition, Deluxe Standard, or Peyronie’s and Curvature Correction Edition).

#2. Phallosan Forte

The Phallosan Forte is a vacuum-based traction device that stands out for its vacuum suction system combined with a belt-style traction mechanism. Unlike traditional penis extenders that rely solely on mechanical stretching, Phallosan Forte uses a vacuum cap to gently hold the penis in place while applying traction with an elastic belt.

Phallosan Forte is known for its discretion and ease of use, allowing users to wear it under clothing during daily activities. The device promotes tissue regeneration by exerting constant tension on the penile tissues, encouraging cell growth and straightening the penis over time.

Phallosan Forte is highly effective for correcting penile curvature caused by Peyronie’s disease. The device's combination of vacuum suction and traction promotes the breakdown of the fibrous plaques responsible for curvature while simultaneously encouraging the formation of new, healthy tissue. Over time, this results in a straighter penis and improved penile function.

Phallosan Forte also provides customizable traction levels, making it easier for users with sensitive skin or more severe cases of Peyronie’s disease to adjust the pressure to a comfortable level.

Comfortable to wear: The vacuum system and elastic belt make it more comfortable for extended use.

Discrete design: Can be worn under clothing during daily activities.

Proven results: Clinically supported for reducing penile curvature and increasing length.

Customizable tension: Adjustable traction levels for personalized comfort.

Requires long-term use: Significant results may take 6 months or more.

More expensive: One of the pricier devices on the market.

Vacuum suction: Some users may find the vacuum system uncomfortable during the initial adjustment period.

How to Use Phallosan Forte

Place the vacuum cap over the head of the penis and create a secure vacuum seal.

Attach the tension belt around the waist or leg, depending on your preference.

Adjust the tension level to apply gentle traction to the penis.

Wear the device for 6 to 8 hours daily for optimal results.

Phallosan Forte is priced at $379 for the basic package, which includes the vacuum system, tension belt, and various size adaptors. It is available on the official website and select retailers.

#3. Penimaster Pro

The Penimaster Pro is a high-end penis traction device that utilizes vacuum adhesion technology combined with a traditional traction mechanism. Unlike other devices that solely rely on mechanical straps, Penimaster Pro uses a vacuum chamber to securely hold the penis in place, ensuring comfort and even pressure distribution across the penile shaft.

Penimaster Pro’s vacuum adhesion system ensures that the entire penile shaft is evenly stretched, which is crucial for treating the uneven, scarred tissue that causes penile curvature in Peyronie’s disease. By applying continuous tension to the curved areas, the device promotes tissue regeneration and gradually corrects the curvature.

Additionally, Penimaster Pro offers a range of accessories that allow for customized tension levels and support, making it suitable for both mild and severe cases of Peyronie’s disease.

Penimaster Pro has been tested in clinical trials, where it demonstrated significant results in reducing penile curvature and enhancing penile length. Users reported an average reduction in curvature by 30% to 40% and a length increase of 0.5 to 1.5 inches after several months of consistent use.

Vacuum adhesion technology: Ensures even pressure distribution and comfort.

Customizable traction: Suitable for both mild and severe cases of Peyronie’s disease.

Comfortable for long-term wear: Less pressure on the glans compared to traditional extenders.

Durable and high-quality materials: Long-lasting design.

Expensive: One of the most costly penis traction devices available.

Complex assembly: Takes time to assemble and adjust properly.

Requires regular maintenance: The vacuum system needs cleaning and maintenance.

Attach the vacuum chamber to the head of the penis.

Secure the traction rods to the base of the penis.

Adjust the device to create a gentle stretching force.

Wear the device for 4 to 6 hours daily for best results.

Penimaster Pro is priced around $360 to $400, depending on the package and accessories included. It is available for purchase directly from the manufacturer’s website.

1. Can these devices permanently fix penile curvature?

Yes, with consistent use over several months, penis traction devices can lead to lasting improvement in penile curvature, particularly in cases of Peyronie’s disease.

2. How long do I need to use a penis traction device to see results?

Most users begin to see noticeable improvements after 2 to 3 months of daily use, though more significant results may take 6 months or longer.

3. Are these devices painful to use?

There may be some initial discomfort during the first few days of use as your body adjusts to the stretching force, but most modern devices are designed for comfort during long-term wear.

4. Are there risks to using penis traction devices?

When used correctly and as directed, penis traction devices are considered safe. However, improper use or over-traction can cause discomfort or minor injuries.

Each of the three top penis straighteners for 2025 offers unique features:

Quick Extender Pro is ideal for those seeking a non-invasive solution for both curvature correction and penis enlargement, thanks to its Double Strap Support technology.
