Evidence Behind Penis Traction Extenders

 

 

Traction penis extenders are devices that keep the penis under traction, with enough force that over time the penis itself gets longer. A lot of things claim to be able to enlarge the penis, but in this case there is legitimate evidence that they work, from peer reviewed medical studies listed on Pubmed. Some are for treating the condition called Peyronie's and others for after surgery care.

 

I thought it would be useful for some to see all the evidence backing up these devices in the one place. I am linking straight to the studies on Pubmed, and will also list the specific lines in each study that show the results achieved. Then readers can decide for themselves if they think the evidence in support of traction devices is legitimate, as I think it is.


I recommend this device - x4 Labs -
 

And on to the evidence. No editorializing has been done by me, all I have done is link to the studies and also display the particular line in the conclusion that pertains to the results achieved. This is solely here so you can decide if the clinical evidence behind traction devices is strong enough.

 

 

http://www.ncbi.nlm.nih.gov/pubmed/20102448 - Effect of penile-extender device in increasing penile size in men with shortened penis: preliminary results.

 

The mean flaccid penile length increased from 8.8 ± 1.2 cm to 10.1 ± 1.2 cm and 10.5 ± 1.2 cm, respectively, in the first and third months of follow-up, which was statistically significant (P < 0.05). Mean stretched penile length also significantly increased from 11.5 ± 1.0 cm to, respectively, 12.4 ± 1.3 cm and 13.2 ± 1.4 cm during the first and second follow-up (P < 0.05)

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

“The authors reported an increase in the mean penile length of 4.1 mm (100.5 mm before and 104.6 mm after PTT) (p > 0.05) and decrease in mean erect penile curvature (EPC) of 14° (from 34° to 20°) (p < 0.05) in this small case series”

 

“Daily use of a penile traction device for 6 h a day in men with PD and severe penile retraction was associated with a longer stretched penile length (SPL) (average 0.8 cm gain)”

 

“PTT of at least 6 h per day for a minimum of 4 months resulted in the mean SPL gain of 1.8 cm (range 0–3.1cm).”

 

“The use of a penile extender device was associated with increased penile length ranging from 1 to 3 cm and appeared to be proportional to the number of hours per month that the patient was wearing the traction device. Furthermore, sustained treatment with PTD for 4 months provided an increase in penile length from 1 to 4 cm.”

“and three types of penile extenders resulted in average flaccid increases of 0.5 cm to 2.3 cm.

Mean stretched and flaccid penile length increased by 1.3 and 0.83 cm, respectively at 6 months.

 

http://www.ncbi.nlm.nih.gov/pubmed/22024053

 

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).Conclusion. 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 [corrected].

Importantly, in those who used traction, there was no perceived length loss, 58% reported a mean erect length gain of 1.1 cm.

 

http://www.ncbi.nlm.nih.gov/pubmed/18452379

 

 The recent trial noted that, over a 6-month period, patients reported increases in penile length of 1-2.0 cm, with an accompanying increase in girth.


https://www.ncbi.nlm.nih.gov/pubmed/25809129


At 6-month follow-up, a mean gain of 1.7 ± 0.8, 1.3 ± 0.4, and 1.2 ± 0.4 cm was noted for the flaccid, stretched, and erected penile lengths, respectively (all P values < 0.001). During the off treatment period, there were no significant changes in penile lengths. No effect on penile girth was observed.

 

http://www.ncbi.nlm.nih.gov/pubmed/18990153

 

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.

Penile length, dorsally measured from penopubic angle to meatus, was 100.5mm before and 104mm after penile stretching.

 


So that is all the evidence available to date on penis traction extenders. Read it and decide if you want to give them a try. It is my opinion and experience that they work, though about half as well as the marketing material would have you believe. But there is no need to trust my opinion, the evidence is all above.

 

As earlier, my recommendation is X4 Labs
