What makes our erection happen ?

I have read many clear and instructive threads on how the erection happens.
But, quite by chance, I was reviewing some lectures on a website called (TED: Ideas Worth Spreading) and I came across this one.

(If the link doesn’t work, just go to ted.com and do a search on penis … this lecture will come up

It is a 11 minute video. Blow past the first 5 minutes of blathering and then towards the middle, this woman gives that i think is the clearest explanation of how the layers of the Tunica and smooth muscle work in the erection.

The woman’s name is Diane Kelly and she has done quite a bit of work on why and how the erection happens in humans and other mammals

I figured that this was the group to share this with

Interesting.

One thing she did make clear was that the way penile tissues are arranged, it makes it impossible to bend or stretch.

Without extraordinary effort, of course.

That’s why I recently began to hang.

I would agree … I really only saw it this morning, so I haven’t had much time to assess what the implications of her work are.

Thus far, my takeaways have been that since she has shown that the collagen fibers of the tunica run north-south in one layer and east-west in the second layer,
it suggest that clamping is likely to be more effective than bundled stretches for girth work.
As for length … it seems that her findings support the idea that manual stretching and manual hanging are effective

An additional benefit from her work is that if you go to her website, she sites and links to the resources that she used. Among the studies that she sites are a number of studies on plastic deformation of collagen fibers (i.e. the stuff that the Tunica is made of). I haven’t had time to look at them but I suspect that they may also be enlightening

I will follow the links when I have a moment.

She made clear in the video that her research had to be outcome-driven, in other words, have financial merit. This would suggest to me things such as cybernetic/organic devices, prosthetics or simply tissue re-generation.

She certainly is extremely interested in cock.
