Relating erection percentages to functional standards
Here at Thunder’s, many exercises make reference to percent erect: 10%, 50%, 90%, 100%. I’ve always wondered, what do those numbers mean? My penis is not equipped with a readout gauge!
In the thread Rzilla’s Chemical Enlargement Program , Longtimer had a post (longtimer - Rzilla’s Chemical Enlargement Program) which contained information from a patent application that related erection percentages to observable performance standards. He was kind enough to provide me with the link to that patent application.
In the patent application http://appft1.uspto.gov/netacgi/nph…=DN/20050065159 , there is a section that relates percentage of erection to functional and observable factors:
 Erectile responses may be categorized according to the following: a 100% response or engorgement is a maximal erection which is very hard, firm and unbendable, a 75% response is the softest response considered. hard enough for penetration, a 65-75% response would be partially engorged but would not be sufficient for penetration and intercourse, 40-65% is not a usable erection for sexual intercourse but will have therapeutic effect for enlargement according to the invention, and a response of less than 40% is a slightly engorged, very soft penis wherein the size of the penis is close to the non-erect dimension of flaccid penis with no discernable significant firmness when it is manually palpated by an experienced health professional, and is probably not useful for penis enlargement.
This information is therefore intended primarily to further the discussion on relating erection percentages to things that we can see and feel, and does not represent a broader endorsement of the source PE patent application.
