Clinical results and peer-reviewed research suggest that Phallosan Forte can help alleviate the symptoms of Peyronie’s disease. It is a state-of-the-art penis extender that uses evidence-based science to break down curvature-causing plaque safely and comfortably. Unlike other systems, Phallosan Forte uses a combination of two technologies: an orthopedic belt and a micro-vacuum. By breaking down damaged tissue, the system has been proven to reduce penile curvature.
What is Peyronie’s Disease?
Peyronie’s disease, also called penile fibrosis, is a condition where scar tissue causes the penis to curve painfully during an erection. Repeated trauma to the penis is the most common cause of this scarring, either during sex or other physical activities, although there is no observable cause in some cases.
Peyronie’s disease will not resolve on its own and may even worsen. However, studies show that early management can prevent worsening and improve the effects of scarring. Traction therapy, or stretching the penis, is a standard treatment to reduce scar tissue. Doctors can prescribe surgery or subcutaneous injections as another approach.
Phallosan Forte offers a practical, non-invasive solution. Clinical studies have proven that our system reduces curvature caused by Peyronie’s disease and other conditions.
How Phallosan Forte Treats Peyronie’s Disease
Phallosan Forte uses traction therapy to treat Peyronie’s disease. To reduce the amount of scar tissue that causes curvature, one must apply a traction device, which mechanically stretches the penis in the opposite direction of the bend. Over time, this process softens the bad tissue and reduces the degree of curvature.
Phallosan Forte’s design marries the efficacy of traction therapy with discretion and comfort. The result is a device you can use in public or even while asleep to treat your condition. Here are some benefits of our system:
- It won’t cause discomfort or pain
- It can be worn discreetly under clothing
- Allergen-free materials
- Won’t dislodge during an erection
- Proven, evidence-based results
For Peyronie’s disease patients, Phallosan Forte’s micro-vacuum system securely holds curved penises of all shapes. Regardless of the severity of your scarring, you can use Phallosan Forte to effectively and safely correct curvature and its associated side effects.
Clinical Study
In 2005, a team of German urologists conducted a clinical trial of Phallosan Forte in 24 men, one of whom had penile curvature. In the study, participants used Phallosan Forte for 2 to 8 hours a day for 6 months. The urologists checked the participants three times: at the start of the study, after three months, and again after six months. Urologists measured the length and girth of the participant’s flaccid and erect penises during each check-up. They also asked participants to report their satisfaction with Phallosan Forte and any changes to erections and sexual pleasure.
The study found that Phallosan Forte produced a statistically significant increase in penis size after just three months. The study also found that patients who used the device for six months saw additional growth at a higher rate. Other key findings of the clinical research include the following:
i. Just over half of the patients reported that Phallosan Forte had increased their erection strength
ii. Nearly half of the patients felt an increase in their libido
iii. No patients reported a decrease in erection length, with a quarter reporting a more prolonged erection instead
iv. 22 of the 24 patients in the trial were satisfied with Phallosan Forte’s performance
v. The patient with penile curvature saw a significant improvement
Curvature Reduction with Phallosan Forte
While doing preliminary assessments for the 2005 clinical trial, urologists noted that one patient had a curve in his penis of 60 degrees while erect. This discovery enabled urologists to assess the effectiveness of Phallosan Forte in reducing penile curvature.
After six months, Phallosan Forte reduced the patient’s curvature to 40 degrees while erect. Although no other patients in the trial had curved penises, this finding is a good sign for those suffering from Peyronie’s disease. It suggests that Phallosan Forte can treat curvature.
Other studies confirm the benefits of traction therapy for treating Peyronie’s. A 2008 study published in the Journal of Sexual Medicine followed 10 men diagnosed with Peyronie’s. At the start of this trial, doctors measured curvature between 30 and 85 degrees. After six months of penile traction therapy (PTT), curvature decreased by an average of 33%. The study also found that PTT caused a girth increase that reduced “areas of indentation of narrowing” caused by Peyronie’s, resulting in a more evenly wide penis.
Our 2005 clinical trial and this 2008 study found that patients who used the traction device for 6 months achieved the best results, with a recommended daily usage time of 4 hours.
More recently, a 2019 review of clinical evidence published on traction devices found that they are a “valid treatment option” for Peyronie’s disease. A similar review from 2019 examined both traction and vacuum devices and found that both offered benefits when used regularly to treat curvature and scarring associated with the condition.
The science shows that Phallosan Forte effectively treats curved penises caused by Peyronie’s and other conditions.
How Phallosan Forte Counteracts Peyronie’s Disease
Its unique combination of multiple treatment methodologies is at the core of Phallosan Forte’s effectiveness at reducing curvature. Phallosan Forte uses a vacuum pump system connected to an orthopedic belt to create an almost imperceptible tension around the penis. The system works to gently stretch the penis while exerting a comfortable amount of pressure on it.
The continual stretching corrects unwanted curvature while the constant pressure breaks down scar tissue by stimulating new cell growth. This new healthy tissue allows Phallosan Forte to counteract the root cause of the problem. A clinical trial was conducted in 2015 with four men to verify the effectiveness of our product in treating curvature.

Phallosan Forte also increases the girth of flaccid and erect penises. This can be especially useful for those with Peyronie’s disease, who often suffer from indentations caused by the condition’s scar tissue. Phallosan Forte’s combination of traction and stretching increases overall girth and can help stimulate tissue growth in these indentations. The result is a noticeably straighter, more evenly wide penis.

Attaching Phallosan Forte
Phallosan Forte is simple to use. The system features an orthopedic elastic belt that straps around the waist and connects to a suction bell and condom sleeve. When you first use the device, you should attach the included foam rubber protector cap to the head of your penis. This reduces strain on your glans until your body adapts during the first few weeks of wearing the traction device. Once your penis is used to the pressure of Phallosan Forte, you may safely stop using the cap.
The first step to using Phallosan Forte is to insert your penis into the glass suction bell. Next, unroll the silicone sleeve and ensure it covers your penis to the base. The video user guide on our product page provides a visual demonstration of these steps for your convenience. Once you have put on the suction bell, it’s time to connect it to the stretchable belt. Insert your sheathed penis into the ring at the end of the belt. Make sure the ring goes all the way down to the base of your penis.
After the belt is in place, you can attach the suction bell and tension clip and set them to the desired pressure. You are welcome to adjust the pressure to whatever level is comfortable for you. Patients should start on the lowest setting and gradually increase to a more pressurised setting to maximise their results.
Phallosan Forte’s belt system will keep your penis comfortably and securely in place against your body while the suction bell does its work. This prevents slippage when you use the device in public and securely holds your penis, whether flaccid or erect.
All elements of Phallosan Forte are non-allergenic, meaning prolonged use won’t cause irritated skin in sensitive areas. Even patients who wore the system for 10 hours a day for 6 months reported no discomfort or irritation.
Treatment Length for Curvature Reduction
Our 2005 study found that most patients saw significant changes to their penis after three months of continuous use. However, the study also found that a six-month treatment period increased penis size and girth even more effectively. Six months of constant usage also treats other side effects of Peyronie’s, such as unstable erections and indentations in erect penises.
The 2008 study yielded similar findings regarding the effectiveness of vacuum traction in reducing penile curvature. After patients wore the device for 6 months, there was a significant reduction in curvature due to Peyronie’s disease.
Regarding time per day, we have noticed that patients who wear Phallosan Forte for four hours daily tend to achieve the best results. Since traction therapy works better the longer you do it, this isn’t a surprise. More time using the device means more stretching.
Based on clinical trial results, we recommend users wear the system for 3 to 4 hours a day, although it is safe to wear for up to 10 hours a day. If wearing it during the day is inconvenient, you can use the system while sleeping.
Takeaway
The main symptom of Peyronie’s is scarring that leads to a marked curvature in the penis during erection. This curvature can cause pain and may lower libido, resulting in shorter and less powerful erections and a loss of pleasure during sex. Phallosan Forte can improve outcomes in all these areas of concern. Clinical trials have tested the system, and it has proven to be an effective way to increase erection duration and strength and can increase penis sensitivity for some men.
The bottom line is that Phallosan Forte is a safe, discreet treatment for Peyronie’s disease. If you’re suffering from unwanted penis curvature, indentions or “hinged” erections, penile pain, erectile dysfunction or other symptoms of this condition, don’t wait. Try Phallosan Forte today.
