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.

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 [words=http://www.mattersofsize.com/forum/showthread.php?64036-My-Best-Work-Ever-Penis-Enlargement-will-Be-Changed-Forever-gt-gt-Gain%20inches%20with%20SRT-Theory-and-Routine]SRT[/words] 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 [words=http://www.mattersofsize.com/forum/showthread.php?64036-My-Best-Work-Ever-Penis-Enlargement-will-Be-Changed-Forever-gt-gt-Gain%20inches%20with%20SRT-Theory-and-Routine]SRT[/words] (among other studies/routines that employ [words=http://www.mattersofsize.com/forum/showthread.php?64036-My-Best-Work-Ever-Penis-Enlargement-will-Be-Changed-Forever-gt-gt-Gain%20inches%20with%20SRT-Theory-and-Routine]SRT[/words] practices.)
