In other words, guys may have women to thank for their greater-than-gorilla-sized genitals.įollow Stephanie Pappas on Twitter and Google+. Men with larger penises, then, may have passed on their genes more readily, resulting in the large-genitals trait being handed down the generations. Human males weigh about half of what gorillas do, but studies peg average erect or flaccid-but-stretched penis length from 4.7 inches (12 cm) to 6.5 inches (16.7 cm).Įvolutionary biologists theorize that large human penises might help remove sperm from competing males during sex, but in an era before clothing, women may have been drawn to mating with men whose genitalia caught their eye. Male humans outgun any other primate species: For example, male gorillas can weigh as much as 400 pounds (180 kilograms), but their erect penis length is only about 1.5 inches (4 cm). The findings might help explain why humans have remarkably large genitalia given their average body size, the researchers wrote. Women with greater body mass per height were slightly more likely than thinner women to weigh penis size more heavily in their judgments of attractiveness, though the difference was small. Women's own features mattered as well, the researchers found: Taller women were more likely to find taller men attractive. It's possible that a larger penis just looked more proportional on a taller man's body, the researchers wrote, or it could be that women were biased against shorter men to the extent that even large genitals didn't help. When the researchers controlled for shoulder-to-hip ratio, they found that a larger penis had a greater effect on attractiveness for taller men. That's good news for guys, according to a 2001 Italian study that found 2.99 inches flaccid to be below average. Beyond 2.99 inches, however, the additional attractiveness per extra length started to decline. Though the effect was less extreme, women also preferred larger penises, at least up to 5.1 inches (13 cm) flaccid, which was the largest computer-generated penis in the study. Shoulder-to-hip ratio was a major determiner of attractiveness, accounting for 79.6 percent of the variation in hot-or-not ratings. The results revealed that women preferred taller men as well as high shoulder-to-hip ratios (meaning that the wider the shoulders were than the hip, the more attractive the man).
