Pumping study

That’s the same study as the one contained in the original thread. More details about it (method) can be found in the posts above, than what’s given in the link, I think?

Ah, I didn’t look back at the first post and was thinking the thread title was referring to the study on elongation that you posted. If the multi-chamber method/protocol was there, I missed it the first time.

No, that link gives a bit more stuff not covered in the stuff I pasted. It might be very useful, especially for guys with peyronies or guys who want to straighten their penis, a bit. Interesting part:

“The small cylinder is more adept at stretching length, the large at girth, and so on.”

I’ve never pumped so I’m not sure what this means?

Thanks!

It means that if the cylinder is smaller (less wide), there will be a more pronounced traction effect along the penis length.

What I meant, is, has anybody who pumps actually found that smaller cylinder is more conducive to length gains? Similarly, has anybody who pumps found out that a wider cylinder is more conducive to girth gains?

I only used and use one cylinder (2.25”). I don’t understand how a smaller cylinder would act more on length as long as you don’t pack the tube girth wise.

Another note:

Not to be too skeptical but the increase in length was stretched length and since subjects have peyronies, any improvement in curve should also increase length, no? Can this study really be used as evidence of length growth in guys with straight ones? Maybe, very useful for guys with curves, even minor ones like mine. A straight dick looks longer.

My sense after pumping on and off over the years is that a smaller girth cylinder that one can ‘pack’ [meaning that the penis expands to fill the interior girth of the cylinder] will ten to focus on the length as there is no more room to expand ‘girth-wise’.

Nothing remotely scientific, just that I tend to feel a ‘pulling’ sensation in a narrower tube while I tend to feel ‘fatter’ in a larger one.

I definantely agree with pumping being a good tool for length and girth. I personally gained my first quarter inch in length from 2 months of pumping 3 times a week for 2 fifteen minute sets back in 2008.

Did you use a tube narrow enough to fully pack it?

Hey pulacalului. I was using a tube that was about 2 inches wide. It was a pretty big tube but I was able to pack it length wise after the first month. I was never able to pack that tube girth wise.

Now I’ve been using the Dr Kaplan Penis Pump for 1 or two fifteen minute sets after my evening hanging workout is complete.
