Penile Traction Clinical Studies

Penile Traction Therapy (PTT)

Clinical Trials and Studies

 

Below we have summaries and links of relevant penile traction therapy trials, studies and resources. Jes Extender, being a genuine medical grade class 1 device can be used for penile traction therapy (PTT). Due to Australian TGA regulations at present we only intend to promote that Jes Extender to be utilised for enlargement of the penis. In the near future we intend to amend the purpose of registration to include all relevant benefits associated with penile traction therapy which includes supporting improvements in erection quality and penile curvature, as can be seen in the ample evidence below.

It is important to note that from our observation, research and customer feedback we consider there is only a very narrow range of traction that should be applied to the penis to support optimal results, this range being in between 600 to 1500 grams of tension. It is within this range all legitimate penile traction therapy devices operate, please be aware of the poorly made imitations that may use very high and unnecessary amounts of tension that have never been formally tested or trialed. Jes Extender is a precision designed and made device that ensures optimal levels of tension can be applied and easily adjusted in real time whenever needed.

Combination of Penile Traction, Intralesional Verapamil, and Oral Therapies for Peyronie’s Disease – Michael R. Abern MD, Stephen Larsen MD, Laurence A. Levine MD – 2012.

Relevant extracts:

Results: “…Multivariate analysis revealed that duration of PTT use significantly predicts length gain (0.38 cm gain for every additional hour per day of PTT use, P = 0.007).”

Conclusions: “There was a trend toward measured curvature improvement and a significant gain in SPL in men using the combination therapy protocol. Length improvement is related to duration of use of the traction device.”

Penile Traction Therapy for Treatment of Peyronie’s Disease: A Single‐Center Pilot Study – Laurence A. Levine MD, Mark Newell PhD, Frederick L. Taylor MD – 2008.

Relevant extracts:

Results: “Subjectively all men noted reduced curvature estimated at 10–40 degrees, increased penile length (1–2.5 cm) and enhanced girth in areas of indentation or narrowing. Objective measures demonstrated reduced curvature in all men from 10–45 degrees; average reduction for the group was 33% (51–34 degrees). SPL increased 0.5–2.0 cm and erect girth increased 0.5–1.0 cm with correction of hinge effect in four out of four men….”

Conclusions: “Prolonged daily external penile traction therapy is a new approach for the nonsurgical treatment of PD…”

Revision of Penile Prosthesis Surgery after Use of Penile Traction Therapy to Increase Erect Penile Length – Daniel J. Moskovic MA, Alexander W. Pastuszak MD PhD, Larry I. Lipshultz MD, Mohit Khera MD MBA MPH – 2010.

Relevant extracts:

Results: “Stretched penile length increased 2.3cm after 6 months of traction therapy. A revision surgery enabled the placement of a prosthesis that was 20% longer in length (15 cm to 18cm), and erect penile length increased by 4.4cm…”

Conclusions: This case suggests that the use of a penile traction device increases penile corporal length, and thus the length of a penile prosthesis that can be implanted in a patient with an unsatisfactory prosthesis already in place. Importantly, this patient experienced a substantial improvement in erect penile length after surgery.”

Penile traction therapy… is effective and safe in the stable phase of Peyronie’s disease: a controlled multicentre study – Ignacio Moncada, Pramod Krishnappa, Javier Romero, Josep Torremade, Agustin Fraile, Juan Ignacio Martinez‐Salamanca, Hartmut Porst, Laurence Levine – 2018.

Relevant extracts:

Results: “Forty‐one patients in the PG [penile traction group] and 39 in the NIG [non penile traction group] completed the study. There was an overall reduction in curvature of 31.2° (P < 0.001) at 12 weeks compared to baseline in the PG, representing a 41.1% improvement from baseline, which significantly correlated with the number of daily hours the device was applied in a dose‐dependent manner. Those patients using the device < 4 h/day experienced a reduction of 15°–25° (mean 19.7°, 28.8% improvement; P < 0.05), while patients using the device > 6 h/day experienced greater curvature reduction, ranging from 20° to 50° (mean of 38.4°, 51.4% improvement; P < 0.001)…Furthermore, SPL increased significantly in the PG compared to baseline and compared with the NIG, ranging from 0.5 to 3.0 cm (mean 1.8 cm; P < 0.05).”

Conclusions: The use of… a non‐invasive treatment, should be offered to patients with stable PD for 3 consecutive months before performing any corrective surgery, as this provided a significant reduction in the curvature, an increase in penile length and a significant improvement of the symptoms and bother induced by PD”

Non‐invasive methods of penile lengthening: fact or fiction? Marco Oderda, Paolo Gontero – 2010.

Relevant extracts:

Conclusions: “In conclusion, penile extenders appear to be an effective treatment for patients who complain of ‘short penis’. The application of such devices can be recommended in all patients regardless of the penile length, because of the low risk of complications. Taking into account that surgical methods are not supported by a better scientific background nor have they shown better results, penile traction devices should be proposed as a first‐line treatment option for patients seeking a penile lengthening procedure.

“The same consideration may apply to Peyronie’s disease where surgical correction of curvature carries a high risk of patient dissatisfaction because of additional penile shortening. The current evidence suggests that selected cases may benefit from a conservative approach with penile traction devices.

“It seems that penile extenders represent the only evidence-based technique of penile elongation. Results achieved do not seem to be inferior to surgery, making these traction devices an ideal first-line treatment option for patients seeking a penile lengthening procedure.”

A Retrospective Comparative Study of Traction Therapy vs. No Traction Following Tunica Albuginea Plication or Partial Excision and Grafting for Peyronie’s Disease: Measured Lengths and Patient Perceptions – James Rybak MD, Dimitri Papagiannopoulos BS, Laurence Levine MD – 2012.

Relevant extracts:

Introduction: Loss of penile length is a recognized and common consequence of Peyronie’s disease (PD). Traction therapy (TT+) has been reported to decrease post‐op length loss as well as increase stretched penile length (SPL) prior to surgery”

Results: Mean length change seen in TAP (TT+) was 0.85cm (0.25–1.75) vs. −0.53 cm (−1.75 to 0.5) in TAP (TT−) (P < 0.001). The mean length change seen in PEG (TT+) was 1.48cm (0–6) vs. PEG (TT−) 0.24cm (−1 to 2.5 cm) (P < 0.001). Sixty‐one percent of surveys were returned; 85% lost length prior to the initial office evaluation, with an average of −2.5cm lost. Importantly, in those who used traction, there was no perceived length loss, 58% reported a mean erect length gain of 1.1cm…”

Conclusions: Loss of length in men with PD remains a serious concern. It appears that postoperative TT can result in length preservation, and in many, a measured and perceived length gain following correction of the curvature.”

Applying Extender Devices in Patients with Penile Dysmorphophobia: Assessment of Tolerability, Efficacy, and Impact on Erectile Function – Nowroozi MR, Amini E, Ayati M, Jamshidian H, Radkhah K, and Amini S – 2015.
Relevant extracts:

Introduction: Most men seeking penile enhancement techniques have a normal penile size. They are either misinformed or suffer from penile dysmorphophobia and should be discouraged from undergoing invasive procedures. Less invasive techniques including penile extenders are not associated with major complications and may be beneficial from a psychological perspective.”

Results: …from 13 patients with mild baseline erectile dysfunction, nine patients reported normal erectile function after 9 months”

Conclusions: “Penile extender as a minimally invasive technique is safe and provides modest benefits and patient satisfaction.”

Therapeutic advances in the treatment of Peyronie’s disease – F. A. Yafi, M. R. Pinsky, P. Sangkum, W. J.G. Hellstrom – 2015.

Relevant extracts:

Introduction: Most men seeking penile enhancement techniques have a normal penile size. They are either misinformed or suffer from penile dysmorphophobia and should be discouraged from undergoing invasive procedures. Less invasive techniques including penile extenders are not associated with major complications and may be beneficial from a psychological perspective.”

Discussion: Penile Traction Therapy… as a single modality, PTT has shown to be efficacious at reducing penile curvature and preventing PD‐associated loss or gain of penile length in patients in both the acute (Martinez‐Salamanca et al., 2014) and chronic (Levine et al., 2008; Gontero et al., 2009) phases of PD”

“Finally, loss of penile length following surgery for PD is a major complaint for most patients irrespective of surgical technique. The use of PTT has, however, been associated with a 1–3 cm gain in SPL when used as a pre‐operative (Levine & Rybak, 2011) or post‐operative (Moncada‐Iribarren et al., 2007) modality in conjunction with definitive surgical therapy for PD. Overall, PTT is an underused tool which, when used diligently, may provide a clinically significant benefit in penile length…”

Conclusions: “…Traction therapy, as part of a multi-modal approach, is an underused additional tool for the prevention of PD‐associated loss of penile length, but its efficacy is dependent on patient compliance…”

Martínez‐Salamanca MD PhD, Alejandra Egui MD, Ignacio Moncada MD, Javier Minaya MD, Claudio Martínez Ballesteros MD, Luis del Portillo MD, Ignacio Sola MD, Joaquín Carballido MD PhD – 2013.

Relevant extracts:

Aim: The aim of this study was to assess the effectiveness of a penile extender device for the treatment of patients with AP of PD”

Results:The mean curvature decreased from 33° at baseline to 15° at 6 months and 13° at 9 months with a mean decrease 20° (P < 0.05) in the PTT group. VAS score for pain decreased from 5.5 to 2.5 after 6 months (P < 0.05). EF [erectile function] and erection hardness also improved significantly. The percentage of patients who were not able to achieve penetration decreased from 62% to 20% (P < 0.03).

“In the NIG [non penile traction group], deformity increased significantly, stretched flaccid penile length decreased, VAS score for pain increased, and EF and erection hardness worsened. PTT was associated with the disappearance of sonographic plaques in 48% of patients.

Furthermore, the need for surgery was reduced in 40% of patients who would otherwise have been candidates for surgery and simplified the complexity of the surgical procedure (from grafting to plication) in one out of every three patients.” [Emphasis added]

Conclusions:“PTT seems an effective treatment for the AP of PD in terms of pain reduction, penile curvature decrease, and improvement in sexual function.”

Wendy Hurn, Urology Specialist Practitioner, Bristol Royal Infirmary UK – 2006.

Relevant extracts:

Discussion It works by gently stretching the penis and elongating the plaque which in turn breaks it down. If worn as instructed initial results should be seen within 3–4 weeks, with full results taking 3–6 months.”

Results:There has been a marked improvement of between 30–45% in the degree of angulation, with reduction in discomfort and the ability to resume sexual intercourse in most cases.

“An [penile traction device] was fitted and used daily as instructed. Patient was seen in clinic after three months and the fibrotic plaque had lengthened and decreased in width, while the penis itself had lengthened by approximately 1.2cm. The patient reported that the curvature had decreased by approximately 20°. He was seen again at six months and improvements had continued with a further increase in length of 1.52cm, plus a decrease in the size of the plaque”.

Conclusions:“For those who cannot or will not undergo the surgical option…[penile traction therapy] is a real alternative. It gives the patient autonomy and allows them to take some control of the situation, while getting positive results. It is extremely important when discussing the options that this is considered an effective and viable treatment, and the practitioner will themselves realise the potential of this device after seeing the positive effects that it can have on their patients.”
