Penis extender

A penis extender is an external medical device with tentative evidence as of 2019 for Peyronie's disease. It acts as a mechanical, traction device that stretches the human penis in the flaccid state to make it longer.[1]

Description

Penis extenders usually have a plastic ring that sits at the base of a flaccid penis, and another ring before the glans penis, with a traction device that runs along the sides of the organ. The wearer adjusts springs, which pull the penile shaft with the intention of stretching the flaccid penis to become longer.[1]

Medical use

There is tentative evidence for use in Peyronie's disease.[1] As of 2019, studies have been small in size; many had difficulty carrying out the treatment during the study period, and people were not blinded to the treatment that they were receiving.[1]

Adverse effects

Adverse effects are not extensively reported in the literature, and they are usually mild and self-limiting, in part caused by lack of patient compliance with penile traction therapy (PTT). The most commonly reported symptoms with PTT include pain, erythema, ecchymoses, and pruritus. Another reported symptom was edema to the pubic bone, which is associated with vigorous usage. All of these adverse events are generally self-limited and resolve with discontinuation of PTT.[1]

It should not be used if penile wounds, lacerations, or infected zones have not fully healed, and by those suffering certain diseases or disorders.[2] Aggressive or incorrect uses of penis extenders can cause damage to skin and blood vessels, among other possible issues.[3]

Penile traction devices, or penis extenders, stretch the tissues in the penis to increase its length. Some research indicates that these devices work. However, they require persistence and dedication to produce noticeable results. ... Individuals interested in trying a penile extender should note that most of these studies involved only small sample sizes. Other criticisms include selection bias, which means that the randomization of the study participants may not be sufficient, and researchers may select them to achieve a particular result. More research is necessary to determine more accurately the safety and effectiveness of these devices.

Penile extenders usually require the penis being in traction for several hours a day for several months, and the researchers wondered whether the gains were worth it. A small number of the men who used penile extenders reported experiencing bruising, temporary discoloration, pain and itching.

'Our study showed that the penile extender device produces an effective and durable lengthening of the penis, both in the flaccid and stretched state,' concludes Dr Gontero. 'If these results are confirmed by further research, we propose that the device should be used as a first-line treatment option for men seeking a penile lengthening procedure.'

Phallosan is an orthopaedic stretch belt for penis enlargement which was launched on the market in 1999. Between July 2005 and January 2005 a study of the effectiveness of Phallosan was carried out under the patronage of Professor Dr. Sohn, Chief Physician at the Urological Clinic at the Markus Hospital in Frankfurt am Main. The data was collected by the clinic's Senior Consultant, Dr. Hanikel. The results of 24 patients from the study were used for evaluation purposes. Two patients were classified as dropouts, but these had no post-baseline measurements and have been excluded from the analyses. They were only included in the analysis of satisfaction levels in the form of a worst-case analysis and classed as dissatisfied. A further 5 patients were marked 'to follow' in the study data and have been excluded (for the time being) from the analysis. The main purpose of this statistical report is to determine whether a (statistically) significant change in penis girth and length can be identified after using Phallosan for six months. For this purpose, univariate characteristics were calculated for these parameters and t-tests conducted of the significance of the enlargement. An allowance was made for the fact that due to repeated application of the test it was a multiple test problem.

'The magnitude of gained length was similar irrespective of baseline size,' Gontero told LiveScience. 'So the device could work also for those men who complain of so-called penile dysmorphopobia [and who] fall within the normal range — the majority — but who are strongly convinced they have a small penis.' The extender, however, didn't fully live up to the claims of its manufacturer, Andromedical, based in Madrid, which boasts of an average gain of 1.3 inches for an erection and a larger girth. Gontero's group saw no significant improvement in girth and no biological mechanism that would support the claim. Perhaps not surprisingly, the study didn't ask whether the men's partners were happy with the change.
