Biomechanical properties of the penis

So we all know that the penis is essentially a sponge with a semi-elastic jacket that allows it to hold form when erect. Biomechanically, the important aspect of that jacket is the tunica. I recently stumbled onto an interesting study that did research on Peyronie’s disease, linked below. Par for the discussion is reading of the study linked below, and doing a bit of your own research. Given that the study below deals with technical analysis, an understanding of engineering and calculus would be useful.

This article makes for a very interesting read because the authors actually did biomechanical modelling of the penis. For all exercises that expand the penis via increasing blood volume, this is very relevant. The blood volume increase in the penis puts a direct stress on the tunica, and by forcing in more blood, the stress on the tunica exceeds what is natural. The researchers modeled the normal stress and volume of the penis in both flaccid and erect states, making some assumptions along the way.

What is of interest is the equations and geometries given in the study, and how they modeled the stresses of the tunica. Because they don’t know much about how the penis deforms, they base their modelling on other known tissue and estimate. Given what our vets know from experience, does anyone think there is a way to mathematically optimize one’s own routine to push just right?

Also, in various other studies, I have read that the composition of the tunica in mammalian penises consists of orthogonal fibers. This make-up of orthogonal-reinforcement is very effective. The modern design of the plastic soda bottle actually relies on the same design concept, that is, to have polymers laid out in a matrix so that the molecule fibers are orthogonal to one another. This facilitates a cyclical re-enforcement when the plastic on the bottle has a stress load put onto it.

Originally when plastic bottles were being invented, many trials worked with parallel polymer matrices, but these always snapped too soon in stress strain testing. The breakthrough came when a orthogonal [cross-hatch] pattern was used in the polymer matrix. It turns out that as the polymer is pulled in one direction, the orthogonal fibers would push the fibers parallel to the pull, which would cause them to resist expansion. This reinforcement would occur both ways on a molecular level, giving the material a great dynamic strength.

Clearly, nature’s design of the tunica implemented that idea eons earlier with the cross-hatch nature of the fibers that bind the CC and CS. Noting the similarity in these matrices on a philosophical design level, I half wonder if a plastic bottle could be used as a rudimentary model for the tunica. Again on a purely experimental line of reasoning, and not one to base PE off of, I half wonder if an efficient method for using pressure to expand a plastic bottle could be applied to methods used to stretch the tunica while avoiding injury. Just a thought. -Yaog

I’m all for gains, but how do I get the Liquid Plumber & foil into my cock to achieve this?:)

I haven’t looked at the link yet, but will do so. Lost a cool link that dealt with the pressures on the tunica and how they are produced. Wasn’t simple “balloon” stuff, it was pretty neat.

I have no idea if the bottle bomb thing really works, just heard about it and your statement created a vivid image in my mind. An image I don’t care to revisit…the cock is NOT a mailbox!

Great/Fun read but not really of much practical value unless you were to delve deeper. But that would require a lot of coffee , adderall and intelligent conversation. So I’ll leave it at: great read, thanks for sharing. Were there any other conclusions that you’ve drawn from your readings you’d like to tell us about?

Why can’t we just jelq/clamp/hang and stop worrying WHY it works?

Because if the why is understood, then gains can be produced when little or none have been produced bythe standard methods.

But that pretty much applies to everything, not just this.

Think about it this way, you spend countless hours reading and thinking of how, and why things work and new techniques, when you could be spending those hours (maybe not all at once) doing techniques that have worked.

What’s wrong with wanting to learn more, I don’t see anything wrong with it, if it helps, even better.

Learning might produce more efficient techniques. And some guys gain little to nadda, so hence the interest in the why.

Have fun with that, I’ll be making my penis bigger, and if you find out anything new that nobody has ever discovered in the history of penis enlargement, let me know.

I’m pretty sure we call that clamping.

Every thing else that was mentioned has basically nothing to do with anything, talking about how plastics resist expansion and other animals tunicas. We can’t reconfigure how everything in our dicks are layed out, so why should we care?

Some people are inquisitive. If not, doods who follow pioneers wouldn’t ______.

In this case, followers wouldn’t know how to pull, squeeze or clamp, or………, or…………, or………… their dicks.

True, but jelqing was performed by the “ancients”. People have learned new things, but we’ve basically gone through it all, I dont think theres one more thing we can do to our poor dicks to make it bigger besides patience.

Thanks yaog. Nice article and contribution. It’s very likely that, at some point, I’ll make use of some of the info contained therein.

Added to Favorites.

Gee, I wonder what all that gray goo in our skull is for? Oh, wait…

Sorry to sound so cynical there Goingfor8, but I don’t understand your resistance. Why bother logging into Thundersplace at all? You got your routine, have you mastered it with only one hand? Did you discover any of the elements you now use in your routine?

Someone has to take the time to think about these things. Frankly, I wish there were more guys out there like Yaog that were intelligent enough to both seek and find new solutions to the question. If you want to go the “brute force” route, more power to you. I prefer “work smart” in lieu of “work hard” when ever possible.

You can bet I will be looking into this, Yaog. Thank you for your input. Keep pushing the envelope.

I know I didn’t come up with anything I do right now. But these techniques have been around for a while, we dont even know who came up with the jelq technique! I’m just saying, I dont think we can improve on whats already here. If you want to learn how plastic bottles are made and how other mammals tunicas are made up, then go ahead and use that gray matter to learn about it, but since we dont posses that structure, why learn about it for PE purposes, we can’t change how are dicks are made up. I’m just saying that your wasting valuable time learning something thats already been learned or is useless information.

I didn’t mean to become an ass, it just seemed pointless, I should have never posted anyways.
