In terms of what constitutes small, big and average, a 2007 study from British urologists Kevan Wylie and Ian Eardley revealed that the average erect penis is 5.5 inches in length and 4.7 inches in girth. According to Wylie and Eardley, most men who suffer from small penis syndrome (i.e., the anxiety of thinking their penis is too small even though it isn’t) have nowhere close to what scientists define as a micropenis. Not to mention, according to one of the studies cited, 85 percent of women surveyed said they were satisfied with their partner’s genitals, whereas only 55 percent of men were happy with what nature had given them. In other words, almost half of the men surveyed would like to have a bigger dick.
Some surgical methods have the most evidence of effectiveness, whereas others have fairly frequent complications, sometimes severe, including scarring that lead, ultimately, to penis shrinkage or erectile dysfunction. Noninvasive methods have received little scientific study, and most lack scientific evidence of effectiveness, although scientific evidence supports some elongation by prolonged traction. Some quack products may improve penis erection, mistaken by consumers for penis enlargement.
