Penile stress/strain relationship

“Contrary to what would seem obvious, the SPS is as effective at 3 x 30 minutes daily as the dynamic is at 8~12 hours daily. Combine that with heat and I think we’re on to something.” - That’s amazing if correct. It would suggest that the penismaster (weight hanging, pumping, etc.) are all inefficient and that instead a simple device which you just screw out to a certain length (providing the constant strain) would be best (like Piet’s homemade stretcher). Of course the question then becomes how much strain is needed - which one can get a feel for with the stress-strain plot.

About the question of heat, I was just throwing out the possibility that too much heat (applied over long times) might hinder growth, though the HSPs are quite interesting and may be why some people have success removing discoloration by heating and then massaging the discolored areas.

Its possible it does that. Certainly people have noticed that heating can help remove discoloration.

Interesting article on the stresses inside an erect penis.

When you look at the colored pictures, be sure to note that the lateral view show the penis upside-down - the urethra is on the top (see crossection on the left side).

Immediate thought - the upper side of the penis (at leas mine) is “harder” than the bottom, and it is easier to bend it upwards than downwards. That makes sense when you look at the stress chart; the upper side of the tunica is already “prestressed” to a higher extent, there is more slack in the underside.

Also, if I understood this right, they treated the tunica as one - whereas mbuc referred to a source claiming that in fact there are three tunica - one for each CC and one surrounding them both. I would imagine that would affect the 3D-model a bit, but maybe not if you are looking at a static situation.

Hmmm. I wonder what the colored pictures would look like if the authors of the paper introduced heat in their model.

Maybe we should mail them a link to this discussion, invite them to join in?

Has anyone ever heard of someone pulling their Dick off? I heard of a gentleman who got his pecker hung up in some type of farm machine. I twisted his pants up and his dick was in his pants. In essence he had more than 100 horsepower pulling on his dick. Luckily they got the machine turned off before it completely pulled his dick off. Heard it was black and blue and swollen badly. I would like to ask this person if his dick is longer than it was before. I wonder how much force your dick could take before it pulled into. Is it possible to pull your dick off with enough weights? Just thinking? Danni

danni,
I’m happy you dug up this thread. I must have missed it last year, and it is an awesome read.
I once saw a western movie where they bound a boy’s dick to a rope and had the boy dragged on his dick by a horse. The dick tore apart. It was disgusting. I do not know how much truth it is in there, but it is sure your dick will tear apart when you put too much stress on it.

My question for the other guys: Has anyone of you tried to apply these models on girth? Or did anyone already figure out an experimental setting to determine girth expansion while pumping or clamping?

This is a great thread :up: Best evidence I’ve seen that heat may matter; I’ll change my tune in response to that PE-FAQ from here on.

Where did Innova go?

I read this thread in hopes of finding more information about static stretching, and I did find a link to another good thread. In the meantime, I was able to read about mbuc’s experiments. The information provided is wonderful. Thanks!

So, what if you heated before and during your stretch, allowing the tissue to relax and stretch, and then applied cold when at your maximum stretch? Not really an expert or anything close in engineering, but just seems kind of interesting…

“The SPS is as effective at 3 X 30 minutes daily as the dynamic is at 8~12 hours daily”

Is this true?

Do you set the tension and keep it there, Or do you increase or decrease the tension during the session?

By the way, It took me less than five minutes to remove the springs from my jes. I just don`t understand why the springs are there in the first place if it makes the extender less effective?

I have a Jes type stretcher and can tell you my only gains have come from stretching above erect length. Any tension below that mark has yielded little or no results to most users. It takes some users many months to be able to stretch beyond erect, but once they do, the gains begin.

I have no idea how much weight equivalent of the tension is, but from my limited experience with hanging, I would say not that much. I have hung 20 pounds before, and the tension was to great to handle for more than a few minutes. But I can stretch for 45 minutes to an hour at max tension with my extender. The brunt of the load is being put directly on the ligs and tunica, and can tell you the soreness can be remarkable. You feel a stretch from your gut to your glans.

In over 10 years of PE, I can tell you my quickiest, easiest and most prominent gains have come from the device.

I believe that creep plays a major roll in the permanent elongation of ligaments. In fact, I have found sources to back it up. Yet, just creep is just one stage of the process. Yes, like ModestoMan stated, "the tissues are eventually restored to their original lengths", but it takes time for that to happen. I have read that 40-60% of the recovery occurs in the first hour after the load is removed from the ligs, but that full recovery may take 24 - 48 hours. The good thing about this is that cumulative creep leads to permanent elongation. So, while we want other tissues of the penis to recover from the pressure of the applied force used to stretch the ligs, we want to stretch the ligs again before they have fully recovered. If the ligs are allowed to fully recover between each session, they merely get stronger. Also, building up cumulative cannot go on forever, because cell degeneration, and inflammation occur at any level of stress on the ligs. The ligs build up a resistance to the specific level of force applied even while creep is accumulating, but at a much slower rate than if they were allowed to fully recover between each PE session.

A link to medical information about ligaments and tendons was posted on a thread in the hangers forum on the thread entitled "More Proof that Long Periods of Hanging May be Beneficial" by RB. Bib reads the link and pastes the important information on the thread, and gives his opinion about how the information can be applied to PE. One excerpt stated that after the ligament was stretched beyond 5.14% the elongation was permanent due to micro trama and possible deformation (I would like to insert ModestoMan’s statement that "permanent deformation takes place by breaking and reforming cross-linkages between adjacent collagen fibers", that may very well be the deformation that takes place to make the elongation permanent). So, by applying the right amount of force, for a long enough duration, creep is induced, then by applying the force once again, additional amounts of creep may be able to add up on the previous amount of creep developed. This would not happen in a perfect 2 + 2 fashion, but more or less in a +2 -1 +2 -1 +2 =4 ( -1 for the partial lig recovery periods between PE sessions).

This PE theory is in line with Big Girtha mantra of "never let it turtle". It supports the fact that gains can be achieved through many PE methods, because cumulative creep can be built up by manual exercises, hanging, extenders, and possibly even ads’s ( I believe that even if some ads’s do not induce creep, that they hold the previous creep earned by hanging or stretching constant, or at the least the ads slows down the recovery of the ligs and prevent the full loss of the creep that was earned). So, build up cumulative creep from one session to the next, but watch PI’s to be sure that other tissues are getting sufficient time to heal/stay healthy. Then, once cumulative creep adds up and the stretched length of your ligs is beyond +5.14%, the elongation of that amount should be permanent due to that deformation that ModestoMan mentioned. So, to reach that deformation, you need to accumulate creep. Last, a decondtioning break would once again somewhat lower the tolerance to force that your ligs have built up, as well as relieve the inflammation and stop the cell degeneration that was caused by stress.

I will post this stuff again, perhaps on a thread of my own, but I will post quotes and sources on that thread. If not on a thread of my own, I will add it to remek’s PE theory thread..

Mbuc-

Does this mean that heat alone was more beneficial for you, or the hot/cold routine?
