A Biologists study of the Penis

I saw this at another forum, and was interested because it is a TED talk. These are always thought provoking to me. I'm hoping to get some conversation with regards to bundled stretches after you see this biologists view of the tunica at the microscopic level : https://youtu.be/u7SWcQaoaRQ

Thank you, I started to watch and will finish at home. Very interesting, especially coming from a woman.

Thanks dude. It's just taboo to be doing this type of research on penises I suppose to an extent and that is why penis enlargement is a very unknown community and ideology.

Here is a copy of the literature which follows this TED video well. I'm more interested in the structure of the tunica in its flacid and erect states. https://www.google.com/url?q=http:/...TJbsOQ&usg=AFQjCNErW8DS4VBex_IKsG1Va1JNRVbGKg

Thank You. I just got through the entire study and wanted to speak on a few points that directly relate to how we gain. As I said in many other studies the Tunica is very dense with an elasticity of about 5%, making it a very important topic of modern PE. Here are some of the more interesting points of the study an my reaction.

the tunica albuginea is made up mostly of thick bundles of type I collagen fibers and a small amount of elastin, although they do not measure the relative percentages of these fiber types in the tissue. Flaccid human and dog corpora also contain highly crimped collagen fibers and lose much of the crimp upon erection.

In the flaccid state the Tunica folds into a thicker flaccid state. This "crimping" is dispelled upon erection when the Tunica enlarges to its maximum size. In becoming erect the same Tunica tissue becomes much thinner than it was in flaccid state. (in erect state the Tunica becomes 43% thinner) This tells us that a.) it is vital to remain extended when flaccid as much as possible. Since the Tunica is thickest in flaccid state long periods of moderate stretching will be best in breaking down the tissue. Pre-stretching the Tunica before all training by using Bundled stretches becomes very important. In erect state, when the Tunica is thinner, we can take advantage of this through Erect Twists and other erect exercises.

In the outer layer, the fibers are arranged parallel to the long axis of the penis. In the inner layer, the fibers run circumferentially around the corpus cavernosum, perpendicu- lar to the long axis of the penis. Fibers at the transition between the outer and inner layers show a lower degree of preferred orienta- tion; this thin layer (Table 1) contains fibers randomly arranged in a single plane.

Understanding this we can see that the Tunica has dense tissue running in parallel and horizontal, much like a woven cloth. In this case my assertions years ago when I created Bundled Stretches was correct. I made the assimilation to a wet towel that is being wrung out by twisting and pulling on it to allow the water to be released. After doing this for some time the towel becomes longer and wider. This is what I realized all those years ago and amazingly this article proves that.

Measurements from transverse and para- sagittal sections of tunica albuginea show that in erect corpora the outer layer is 43% thinner than in flaccid corpora; the inner layer is 36% thinner in erect corpora. Fibers in both layers have diameters of 32.8 (2.05) μm, n 5 10 measurements for each layer. Mechanical behavior of the corpus cavernosum during erection: The effect of folding and crimping.

Changes in penile dimensions during erection are brought about exclusively through the macroscopic unfolding of the tissue and the straightening of crimped collagen fibers as the corpus cavernosum fills with blood. The folded tissue and crimped fibers allow the corpus cavernosum to expand simulta- neously in length and width during erection; fibers in the thin transition layer may bind the highly organized outer and inner layers together and accommodate shear strains be- tween the layers as the corpus changes its shape and size. But the axial orthogonal fiber array gives the tunica albuginea a mechanism for stop- ping its shape change once it approaches its maximum volume. Hydrostats reinforced by crossed-helical arrays of fibers can still change their dimensions when their fibers are fully extended by changing the angle the fibers make with the long axis of the struc- ture (Clark and Cowey, ’58; Wainwright, ’88). For example, a short and fat crossed-helical hydrostat with a fiber angle close to 90° can increase its internal volume and become longer and thinner because its reinforcing fibers reorient, reducing their fiber angle toward 55° (Clark and Cowey, ’58). In con- trast, the parallel and perpendicular ar- rangement of collagen fibers to the long axis of the corpus cavernosum means that once the fibers are fully extended any further increases in intracavernosal volume will place them in tension. The axial orthogonal array will therefore prevent further changes in the length and girth of the corpus caverno- sum, giving it a reproducible maximum erect size.


So to dumb this down a bit in erect state there is a predetermined stopping point that limits the erection to it's maximum size determined exclusively by the Tunica. What we should take from this is that Flaccid Bundled Stretching, Erect Stretching and Erect Twists will be the most important exercises in deforming the Tunica. This is not so much a huge new discovery more of a huge discovery that has not been tapped into until SRT came out with the newest studies. It brings great support to our theories and brings them closer to laws.

The axial orthogonal array gives the erect corpus cavernosum the ability to resist ten- sile and compressive forces. Because venous outflow is restricted through the corpus cav- ernosum when it is erect (Hanyu et al., ’87; Andersson and Wagner, ’95), it remains at constant volume throughout copulation. So forces on the end of the erect penis that would tend to telescope its length and in- crease its girth are directly opposed by the high tensile modulus of the circumferential collagen fibers. Similarly, compressive forces from the vulvar musculature that would tend to extend the erect penis are directly op- posed by the longitudinal collagen fibers. Therefore, the array gives the erect corpus cavernosum a fixed shape.

At first read it may seem discouraging but it truly isn't. The fixed size will remain at it's maximum size and as the study reflects changing this is difficult but we already know this so why do we even care about this? Read on.

The axial orthogonal fiber array is also the collagen fiber arrangement that gives maxi- mum flexural stiffness (Koehl et al., ’95). In an erect corpus cavernosum, bending forces put the longitudinal collagen fibers on one side of the array directly into tension. Bend- ing experiments with inflatable models sup- ported by fiber arrays have shown that cylin- ders supported by axial orthogonal arrays have a higher flexural stiffness than those supported by crossed-helical arrays (Koehl et al., ’95). However, collagen fibers do not resist compressive forces well, so large bending forces will tend to make the structure fail on the side under compression, giving the penis a sharp kink. Penile kinking has been observed in copulating dogs (Grandage, ’72) and rhinoceros (Fish, personal communi- cation).
Three- dimensional folds and crimped collagen in the flaccid tissue allow the corpus caverno- sum to expand during erection; the axial orthogonal array stops the expansion at a repeatable maximum size.

Now we can see the full spectrum of this study and how it directly relates to our own conclusions found in SRT (among other studies/routines that employ SRT practices.) The part I underlined brings great support to the entire SRT study.

I truly appreciate this MoreThanLuck, It really brings a great deal of support to SRT and the work all of us have put into it.

You are more than welcome. I believe there is an optimal way of doing things. Coming into PE as a beginner is cumbersome. I know myself, like many other individuals started this journey because our wives or girlfriends said something or we decided to dig for too much information. For myself, after I went through the first 4 stages of grief, I never accepted that I couldn't do anything about it. I'm an engineer for god sakes! I can do anything and have proven it to myself over and over again. I just need to first understand the problem before attacking it blindly. This research is what that provides. Now what I want to get my hands on is that same fabric structure that this biologist showed on stage. The one with the fibers at 0 and 90 degrees. I just want to see how the fibers move when under different kinds of stress.

Thanks for the clarifications DLD and the comparison of ideas.

Haven't read all of this yet, but considering the fact that pe is designed to take advantage of and elaborate on the elastic properties of the penis, specifically the tunica, is it not feasible to assume that the elasticity would increase over time and moreso with greater force applied?

Kinda like how a rubber band, or better yet a silicone cock ring, becomes more elastic through prolonged use or persistent stretching. As an aside, with gains that 5% obviously becomes exponentially more valid over time.

I've got to assume the science of pe will be explored in my lifetime. Would love to see the naysayers then.

Very interesting article! And it justifies the recent buzz surrounding the bundled stretches here in the forums.

But one even more amazing finding (correct me if I'm wrong): if the tunica thins out by 43% in an erect state elasticity of that tissue gotta be way more than 5%, more like...43%. This makes tunica work even more important.

This raises another question: where did the hypothesis about the 5% come from? and furthermore: may it hold true if applied to the condition of a penis in flaccid state (i.e.: is elasticity of the tunica in flaccid state limited to 5%)? In that case a lot more emphasis should be put on erect twisting and stretching since it would be way more efficient to work on the tunica while being in a max elastic state.

Thanks! There was so much that was parallel to our ideas and I only thought on this directly after reading. I will spend more time later looking up the references and reading those studies. Good stuff my Brothers!

This is really amazing stuff actually!

I have a whole lot of experience working with rope. And wires. Like kevlar. Poly or steel.

And if i should apply that iwould say from experience that the best way to apply bundles would be through super sets.

So basicly instead of using them for warm ups

Do them between each other exercise.

Another great one would be to attach the lm. And then just start and turn it around until you're max bundled (while still applying force) and then twist it the other way around.

So the tension is the same. But the fobers get twisted. Around repeatedly.

This.. This can actually be huge for pe!

How does the tissue look in the glands?

The Tunica stops short of the glans.

Would still love to here some statements of you guys on this subject, especially DLD. I'll go for erect twists and stretches to be on the safe side for now. If the tuncia is much thinner and thus much more elastic in an erect state, it should be a no-brainer whether to do flaccid or erect bundles.

I was thinking this as well. My only issue with the idea of erect bundles is what happens to the blood when creating that twisting action. I see it as a long baloon filled with air. If you squeeze one side the pressure on the other side increases proportionally. The only problem is with the penis, if you squeeze the top, blood flows back into your body. Has anyone done these clamped off at the base?

put one hand at the base and the other under the head. twist it at the head. while you clamp as much as needed.

then. if you want to increase the tension. simply twist the base hand the opposite way of the head hand. it doesn't have to be much. GOOD STUFF

The Glans of the penis is the Corpus Spongiosum, but it does not hold expansion because there is no Tunica covering to hold the expansion. This is why, for the most part, enlarging the glans is hard if not impossible. As you can see in this illustration the Tunica ends at the frenulum and the Corpus Spongiosum continues to form the head.

Really?I have always had the idea that you can increase the size of the head.

The biggest issue is there is no skin or Tunica to hold the expanded size. The head tends to go back to it's original size. What can be done is millions and millions of Kegels This, with a flex of the PC muscles, will blow your head up to it's maximum size.

My head has gotten smaller ever since 6 months of PE and I don't know how to make it big again. Hopefully kegels will help.
