RestoreX and RestoreXL: What the Clinical Research Really Says

If you’ve been researching treatment options for Peyronie’s disease or looking for ways to restore penile length after prostate surgery, you’ve probably come across the RestoreX and RestoreXL traction devices.

Both devices are designed to help men improve penile health without surgery, but they are intended for different conditions and treatment goals.

RestoreX is backed by multiple clinical studies showing it can help reduce penile curvature, restore lost length, and improve sexual function in men with Peyronie’s disease. RestoreXL builds on the same traction technology but is designed specifically for men whose primary concern is penile shortening, particularly after prostate surgery.

Here’s what the research says in plain English.

What are RestoreX and RestoreXL?

The RestoreX traction device was developed to treat men with Peyronie’s disease, a condition where scar tissue develops inside the penis, causing curvature, shortening, painful erections, and sometimes erectile dysfunction.

The RestoreXL is designed for men who are experiencing penile length loss without significant curvature, most commonly after radical prostatectomy or other medical conditions that affect penile length.

Unlike many older traction devices that often required three to eight hours of daily use, both RestoreX and RestoreXL are designed for treatment sessions of just 30 to 60 minutes per day, making them much easier to incorporate into everyday life.

Does RestoreX actually work?

The strongest evidence comes from a randomized controlled clinical trial, which is considered one of the highest standards in medical research.

Researchers followed more than 100 men with Peyronie’s disease and compared those using RestoreX with men who received no traction therapy.

After three months, men using RestoreX experienced measurable improvements in several important areas.

Straighter erections

On average, men reduced penile curvature by approximately 12 degrees, while the control group saw virtually no meaningful improvement. Overall, about three out of four men experienced some improvement in curvature.

Increased penile length

Length loss is one of the most frustrating symptoms of Peyronie’s disease.

Men using RestoreX gained an average of 1.5 to 2 centimeters of penile length during treatment. Nearly 95% of participants experienced some measurable increase in length.

Better sexual function

For men who also had erectile dysfunction, researchers found improvements in erectile function scores and several measures of sexual satisfaction.

Many participants also reported feeling less bothered by their condition and more confident during sexual activity.

Do the results continue over time?

Yes, provided treatment continues.

Researchers followed participants for up to nine months. Men who continued using RestoreX generally maintained their improvements and often gained additional penile length over time.

At six months:

• Average length gains reached about 2 centimeters
• Curvature improvements remained significant
• About 61% of men experienced meaningful straightening, averaging roughly 17 to 21 degrees of improvement
• Most men reported satisfaction with treatment and preferred RestoreX over other traction devices they had previously tried

Can RestoreX be used with Xiaflex?

Many urologists combine RestoreX with Xiaflex (collagenase) injections, which are FDA-approved for certain men with Peyronie’s disease.

Clinical research suggests the combination may produce better outcomes than Xiaflex alone.

In one study, men using both treatments were more likely to achieve significant curvature improvement, more likely to regain penile length, and more likely to experience meaningful overall improvement than men receiving injections without RestoreX.

What makes RestoreXL different?

While RestoreX is designed to correct curvature and restore length, RestoreXL focuses exclusively on penile length restoration.

RestoreXL does not include the counter-bending technology found in RestoreX because it is intended for men who do not have significant penile curvature. Instead, it delivers controlled traction that is optimized for restoring length using the same patented traction principles that made RestoreX successful.

Like RestoreX, RestoreXL is designed to be used for 30 to 60 minutes per day, making treatment much more practical than traditional traction therapy.

Who may benefit from RestoreXL?

RestoreXL may be a good option for men who:

• Have undergone a radical prostatectomy and want to help preserve or restore penile length
• Have experienced penile shortening following surgery, radiation, or another medical condition
• Have little or no penile curvature and therefore do not require curvature correction
• Are looking for a non-surgical treatment option to support penile rehabilitation

For many men recovering from prostate cancer treatment, restoring penile length can also have a positive impact on confidence, intimacy, and overall quality of life.

Is RestoreXL clinically supported?

RestoreXL is a newer product, so it does not yet have the same body of published, device-specific clinical research as RestoreX.

However, it was developed using the same traction therapy principles established in RestoreX research and is supported by evidence showing that penile traction therapy can help preserve erectile function and reduce penile length loss during recovery after prostate surgery.

As additional clinical studies are completed, the evidence base for RestoreXL is expected to continue growing.

Which device is right for you?

Choosing between RestoreX and RestoreXL depends on your individual condition and treatment goals.

RestoreX may be the better choice if you:

• Have Peyronie’s disease
• Have penile curvature or an hourglass deformity
• Want to improve curvature while also restoring lost length

RestoreXL may be the better choice if you:

• Have experienced penile shortening after prostate surgery
• Have little or no penile curvature
• Want to focus primarily on restoring penile length during recovery

Your urologist or men’s sexual health specialist can help determine which option best fits your needs.

Is RestoreX safe?

Overall, the research shows RestoreX is well tolerated.

The most commonly reported side effects include:

• Mild discomfort
• Temporary redness
• Minor skin irritation

These symptoms generally resolve within minutes after treatment, and researchers reported no significant long-term safety concerns during clinical trials.

RestoreXL uses the same general traction principles and was designed with comfort and ease of use in mind. As with any medical device, following the manufacturer’s instructions and your healthcare provider’s recommendations is important.

How strong is the evidence?

Compared with many penile traction devices, RestoreX has one of the strongest clinical evidence bases currently available.

Its strengths include:

• Randomized controlled clinical trials
• More than 100 study participants
• Objective measurements of penile curvature and length
• Publication in peer-reviewed urology journals

Like all medical research, there are limitations. Most studies followed patients for less than one year, and additional long-term research will continue to improve our understanding of treatment outcomes.

RestoreXL currently has less device-specific published research because it is newer, but it is based on the same clinically validated traction principles that have made RestoreX one of the most studied traction devices available.

Key Takeaways for Sexual Health

RestoreX and RestoreXL are designed to help different groups of men, but they share the same goal of providing a non-surgical way to improve penile health and quality of life.

If you have Peyronie’s disease, RestoreX is supported by strong clinical evidence showing it can reduce curvature, restore penile length, and improve sexual function with consistent daily use.

If your primary concern is penile shortening after prostate surgery or another medical condition, RestoreXL offers a focused approach to length restoration using the same proven traction technology in a simplified design.

Both devices are intended to be used under the guidance of a qualified healthcare provider. With consistent use and realistic expectations, they can play an important role in helping men regain confidence, restore function, and improve their overall quality of life.
