If you’ve perused the PEGym member forums, chances are you’ve happened upon several of our members who’ve had positive results with penile extenders. However, if you’re new to penis exercising, you still may be a bit skeptical. Now, The Journal of Sexual Medicine has released study findings giving scientific evidence supporting the efficacy of penile extenders in increasing penis length.

What Are Penile/Penis Extenders

Penis extenders are a type of traction device. Most devices consist of a ring that goes around your penis and sits flush against your body and a fastening device that goes around your penis, right before the glans. Bars separating the two fastening points can be lengthened to put tension on the penis, stretching it, while in a flaccid state.

The Penile Extender Study Participants

Twenty-three men, with a mean age of 26.5 years of age, entered into the study. All of the patients complained of having a short penis. Patients seeking girth only enhancement were excluded, as the study focus was primarily on length improvements. Medical histories were taken, to ensure there were no anatomic penile disorders that would negatively affect the use of the penis extender.

The Penile Extender Study Method

The subjects were asked to wear the penis extender per the following protocol:

1. During the first 2 weeks, participants wore the device daily for 4 to 6 hours per day, and increased the length of the penile extender a 1/2 cm every 5 days.
2. From the beginning of the 3rd week to the end of the 2nd month, participants wore the penis extender daily for 9 hours a day, increasing the length a 1/2 cm every 2 weeks.
3. During the 3rd month, the participants continued to wear the penile extender for 9 hours a day, increasing the length a 1/2 cm every 2 weeks.

Study participants were followed up with at the end of the first and the third months. During each visit, penis length and circumference were measured by the same physician, to help ensure measurements were taken consistently. Measurements were taken for both flaccid and stretched length numbers, proximal girth, and circumference of the glans.

Penile Extender Study Results

Positive results were found concerning both increases in flaccid and stretched penis length, with the use of the penile extender. The results were as follows for flaccid penis length:

• Starting mean penile flaccid length for participants – 8.8 cm
• End of the 1st month mean penile flaccid length – 10.1 cm
• End of the 3rd month mean penile flaccid length – 10.5 cm

This showed an average increase of 1.7 cm in flaccid length by the end of the third month.

Similar results were found for stretched length increases. The results were as follows for stretched penis length:

• Starting mean penile stretched length for participants – 11.5 cm
• End of the 1st month mean penile stretched length – 12.4 cm
• End of the 3rd month mean penile stretched length – 13.2 cm

This showed an average increase of 1.7 cm stretched length by the end of the third month as well.

There were no significant improvements found in penile girth. However, the circumference of the glans did show an average increase of 1/2 cm between the first and the third month.
