Just a couple of anatomical details of the subdermal areas of the pernis that might help members understand what is happening with the accordian effect seen above.. The skin of the penis is connected to an almost gelatinous layer of loose aerolar tissue that is extremely mobile which accounts for the ability of the tip of the
Foreskin to slide almost to the base of the pernis with an
Erection.As the skin leaves the abdominal area the subcutaneous adipose skin thins out and at the inguinal ligament which is on either side of the pubic bone it transforms into this stretchy tissue. That envelopes the penis. We refer to this layer as the Dartos layer as it merges into the scrotum it becomes more of a smooth muscle layer that with contraction allows elevation of the testicles to allow regulation of temperature for sperm production and allows for emission of sperm with ejaculation. There are a few of these fibers along the shaft of the penis and more of these fibers in the
Foreskin that allows for shrinkage of the penis when stimulated and closure of the
Foreskin over the tip of the glans.
Now when one injects into this aerolar area it can be injected close to the dermal layer and the subsequent production of collagen will form closer to the dermis or skin which would promote the accordian effect seen in the pictures in this blog. However, if injected closer to the fascia(which is called Buck\'s fascia) then the collagen formation will form closer to this fascia and attach to it allowing the normal mobility of the skin over it. and no accordian effect. To promote the placement into the appropriate area a blunt
Catheter needs to be used, where a needle would place it in a less precise area that would be variable depending upon the ability of the person placing the filler and his experience of knowing he is in the appropriate space.
Another thing to consider is that PMAA will form a sheet of collagen (scar) tissue that is permeated with little tiny plastic spherical shape objects(from histology slides). This tissue when it becomes thick enough does give bulk and a firmness like scar tissue but it is poorly perfused with blood vessels as with most scar tissue it is friable and when damage doesn\'t heal well like regular tissue. It explains why simple trauma to this tissue can progressively go from a little problem to a big problem pretty quickly. There is little vascularity to the tissue(lack of blood vessels) This would occur as this tissue layer becomes thicker. and looses its contact with surround blood vessels which the penile aerolar tissue has a lot of. these small vessels accounting for the darker color of the penile skin..
Hope this helps one understand a little of what each member here is doing to their member.
