If there is any elastin (there must be because it does stretch flaccid to erect) then stretching the cord should result in more elastin and collagen production like in the rest of the tunica. That is the whole mechanism behind PE gains.
One would hope. But the issue for some of us is that this dorsal thickening is so dense and inelastic that stretching it starts to feel like a near impossibility. Okay, maybe not an impossibility, but damn difficult.
