Knowing whether you are limited by Dorsal Thickening/Septum

The tunica albuginea [7] of the corpora cavernosa is a bi-layered structure with which the collagen bundles of the inner layer are arranged circumferentially and those of the outer layer are arrayed longitudinally (Figure1). The inner layer completely contains and, together with the intracavernosal pillars, supports the sinusoids. There is a paucity of outer layer bundles, resulting in a weak sector which may be susceptible to surgical trauma during penile implant [10], at the region between the clockwise 5 and 7 o’clock positions, where there are two triangular ligament structures. These structures, termed the ventral thickening, are a continuation of the left and right bulbospongiosus muscles. There is close contact between the corpora cavernosa and the corpus spongio-sum. On the dorsal aspect, between the 11 and 1 o’clock positions, there is again a dorsal thickening of the outer longitudinal tunica, a radiating aspect of the bilateral ischiocavernosus muscles. Distally they are grouped into the glans penis, forming the distal ligament, an indispensable continuation of the outer longitudinal layer of the tunica located at the 12 o’clock position of the distal urethra. It is arranged centrally, and acts as a trunk of the glans penis. The median septum is incomplete with dorsal fenestration at the pendulous portion of the penis, which is diverged so widely from that depicted in the traditional textbook. Its amount of fenestration is commensurate with the quantity of the intracavernosal pillars. Thus, at a distal penis, the pillars are numerous where the septum is most incomplete, in order to allow for the tensile capability.

The tunica albuginea had been consistently described as a single layer with uniform circumferential thickness. It is, however, unequivocally a bi-layered structure in which the outer longitudinal layer can be regarded as a tendon-like tissue of the finger in the extremities. Thus, it is indeed a continuing structure of the skeletal muscles positioned proximally. The two-layered design is functionally similar to that of a bicycle’s tire, where the inner tire is responsible for confining the inflated air (blood in a sinusoid of the penis), and the outer tire is responsible for supplying strength. It is, therefore, a bi-layered tunica which can meet the requirement for rigid erection. This anatomical knowledge is deemed to be a prerequisite for clinical surgeons who attempt to perform surgeries on the delicate tunica albuginea.

The distal ligament of the glans penis has been overlooked in our published reports. This unique anatomical arrangement may explain why the glans penis is strong enoughto bear the buckling pressure of coitus, as well as how an erect penis is sufficiently rigid but never compresses the corpus spongiosum, which, otherwise, would present an obstacle to ejaculation. Without this strong ligament, it would be like a Christmas tree without a trunk and an umbrella without a stick. A detailed comprehension of the penile anatomy is, therefore, certainly meaningful, and could provide a further foundation for penile surgical techniques and methods.

What, no arterioles?

You mean Shilow wrote that paper ?!?

Foryourprivacy - Penis extenders & septum

I don’t think you and fellows who are speaking of this ‘limiting factor’, like FYP that I quoted, are speaking of the same thing.

You have DT, this is not ‘abnormal’, doesn’t feel like a tendon, it is not in the middle and doesn’t cause a curvature. They feel something different. What Tweaking thinks about that?

I believe that the “cord like feature” is actually the complex of deep dorsal vein, dorsal arteries, and dorsal nerves that are superficial to the tunica and septum, yet are completely enclosed by Buck’s Fascia.

“Buck’s fascia has a dense structure and is composed of longitudinally running fibers; it is firmly attached to the underlying tunica albuginea and encloses the deep dorsal vein, dorsal arteries and dorsal nerves.”

there is an illustration on wikipedia

it is marked “deep fascia”

This seems correct in my experience. I had this situation and still do, just as described in the thread, but after some hanging my BPFSL is longer than BPEL, though only slightly. All other descriptions, including the meaty BPFSL with a clear palpable dense chord in the middle, are accurate.

Good thread. We need a solution.

Why do you say that? It seems like exactly the thing I’m talking about.

It does feel like a tendon, as I’ve said. It is in the middle (between 11 and 1 o’clock positions, consisting of left and right “bands,” which are nearly indistinguishable from the outside). It may cause a curvature (saying it “does” is a conclusory statement, which I am avoiding because I think there are other variables involved).

I believe we are talking about the same thing.

Veins, arteries, and nerves do not provide much resistance to tension. The DT of the tunica does. Why deny the existence of this structure, which is clearly documented in the literature?

Buck’s fascia is “firmly attached” to the tunica. It is much thinner than the tunica and does not provide nearly the same resistance to tension.

‘To the sides’ of the septum means that there actually two cords, not one; and sides, so not in the middle, since septum should be in the middle - I know that one CC could be greater than the other, ok, but anyway whatever is at the sides of the septum should always be farer from the middle of the penis than the septum.

Don’t know, maybe my bad understanding of English is causing some confusion to me, if so forgive please.

No way he wrote that paper. Not only are the arterioles unaccounted for, but the telescopic effect isn’t hit upon either. Shilow’s effort would have been just as over worded though. ;)

Anyway, let’s say one has nor DT neither this ‘fibrous cord’ I’m supposing could be the issue. Neverthless, your penis can’t be stretched without limits.

Let’s say your penis is composed only of CC: at a given point, you can’t stretch it anymore. How this will be felt? If the penis is flaccid, I guess what you’ll feel is kinda two tough cords that you’ll suppose are your ‘limiting factors’. See what I’m trying to say? If there isn’t a distinct, objectively identifiable part of your penis that is tougher, ‘limiting factor’ could be just..well, your mind. :)

Yea, and maybe I’m stressing the 2-sides point to a fault. In reality, they might be merged into one. At any rate, they’re so close that I’ll be damned if I can tell them apart.

The two sides do have two distinct origins, however, i.e., the two ischiocavernosus muscles.

If your penis were composed only of CCs, with no tunica, DT, or “fibrous cord” around them, then it would basically be made of blood vessels and smooth muscle. I’d think that, with a good yank, you could pull the thing right off! The limiting factor at that point would be that you’d have no penis :) .

Haha, you are eluding the point old fox. :)

Seriously, I have no idea that I’m avoiding any point.

Is the point that “limiting factors” are in our heads? Okay, then, but I think of “limiting factors” as obstacles to be overcome, not as reasons to stop and throw in the towel.
