In 2006, a clinical study on such devices proved that they can actually enlarge a man's penis.
Below you can read a quick summary of this pilot study that proves the efficacy of these devices. This study didn't use a penis extender that is commercially available but instead a generic, custom made just for the study.
Now let's procceed with the actual study, named:
"A pilot phase-II prospective study to test the ‘efficacy’ and tolerability of a penile-extender device in the treatment of ‘short penis’
30 patients complaining of having a short penis’ between March 2005 and April 2006 were referred to this 6 month pilot study. However, only 21 were eligible.
The main reason for exclusion was refusal of the patient to comply with the treatment (5 refusals) and/or ineligibility resulting during psychosexual counselling (4 exclusions). Additionally, four patients decided to discontinue the treatment, three after 3 months (one having achieved satisfactory results, one for lack of efficacy and one due to his inability to comply with the protocol), and one at 1 month who reported various side-effects (pain and penile bruising).
So, a total of 15 patients were examined to test the efficacy of the extender device after six months of use. All eligible patients were counselled on how to use the penile extender for at least 4 hours/day for 6 months. Penile dimensions were taken after one, three and six months. Penile dimensions were also measured 6 months after the patients had stopped using the device.
All patients were asked to use the device for a period of six months for at least 4 hours per day (preferably 6 hours per day). They were also asked to sign an informed consent before the study started. The median time that the device was used per day was estimated to be:
- 5 hours during the second month
- 5 hours during the third month
- 4 hours during the sixth month
After 6 months of use, the patients had a mean length gain of 2.3 cm for flaccid penis and 1.7 cm length gain for stretched (erect) penis. Six months after the end of the study, penile dimensions were taken again and it was found that the gains were full retained despite of not using the device.
It should be mentioned that all patients referred were complaining for having a short penis. However further examination showed that they all had an averagely sized penis and none had a true micro penis (which is what doctors define as short penis).
The study concluded that penile extenders should be regarded as a minimally invasive and effective treatment option to elongate the penile shaft in patients who want a larger penis
Here is an extract taken from the study:
"After 6 months the mean gain in length was significant, meeting the goals of the effect size, at 2.3 and 1.7 cm for the flaccid and stretched penis, respectively. No significant changes in penile girth were detected. The EF domain scores improved significantly at the end of study. Treatment satisfaction scores were consistent with acceptable to good improvement in all items, except for penile girth, where the score was either 'no change' or 'mild improvement'."
I want a penis extender too!
If you are now looking for a penis extender, from my personal experience I suggest you to try out sizegenetics. For more information you can check my sizegenetics review and the Sizegenetics FAQ. Recently, a reader also shared his story on how sizegenetics helped him to gain 2 inches after 1.5 year of hard work.
