Extract from the Wessells paper study regarding the penis length methodology. You can see here the evidence that the scientists used the bone pressed measurement methodology. The article states that: “Measurements were made of the length from the pubo-penile skin junction to the meatus, circumference at the mid shaft and fat pad depth by pushing the tape into the pubic bone.” Thus, the erect, flaccid and stretched penis size average does not count the fat pad depth.
