Academic studies on PE
There are some interesting-sounding studies on PE cited in this article:
It would be interesting if the brain trust here got a hold of these and analyzed them.
The corpora cavernosa in the male penis is similar in construction to the pore cells in marine life called sponges. Repeatedly stretching the pore cells in a live sponge will cause it’s absorption pores to expand and heal in this expanded state to adapt to the minute tearing of the cellular walls of the pores, thereby making the pore cells larger and more capable of absorbing more water and nutrients.
The corpora cavernosa is a live tissue which responds similarly in the manner of a sponge (Martini, 1998); therefore, continuous stretching and healing should cause the distensible blood spaces to increase their ability to absorb more blood, as a sponge does with water, and thereby increase actual size of the erectile tissue.
