Study: Women prefer large penises. DUH!

size-mattersBigger is better, at least according to new research Women prefer big penises, thunders a new study published this week in the Proceedings of the National Academy of Sciences.

Researchers had 105 heterosexual women (average age: 26) rate 49 nude images of male bodies. Their task? To rate each on a scale of 1 to 7, with each figure controlled for three different traits: Height, shoulder-hip ratio, and penis size.

Here’s the sexy stuff the women were asked to look at: After controlling for the other two variables (height and shoulder-hip ratio), Australian National University researchers were able to confirm their suspicions: Bigger is better. As you increase penis size, the amount of attractiveness scores gets bigger,” post-doctoral researcher Brian Mautz tells NBC News.

The biologists behind the study theorized that penis-size may have played a significant role in human evolutionary history. “It’s not totally clear why women prefer bigger penises,” explains National Geographic, “but studies have shown that women prefer larger sizes because they can increase sexual satisfaction.” Oh?
