Everyone knew it already, but now a new study published in the journal Proceedings of the National Academy of Sciences (PNAS) confirms that women prefer men with bigger penises.
“Penis size does affect attractiveness,” University of Ottawa researcher Brian Mautz told NBCNews.com.
Teams from the University of Ottawa and Australian National University created 49 computer-generated, nude, male figures, which varied in height, shoulder-hip ratio and flaccid penis size.
The figures were shown to 105 Australian women, with an average age of 26, who were asked to rate attractiveness on a scale of 1-7.
“As you increase penis size, the amount of attractiveness scores gets bigger” said Mautz.
However, the good news for men is that after three inches attractiveness still increased, but in smaller increments.
Heavier females had stronger preferences for big penises.

“The results of the PNAS study are consistent with a mate-choice perspective,” said Brody. “Our results support the hypothesis that female mate choice could have driven the evolution of larger penises in humans.”
The study did not include mate choice factors like money, intelligence or hair, so penis size may not be the most important factor among women.
