A newly published study by the University of Ottawa has positively linked the size of a man’s flaccid penis to his attractiveness to members of the opposite sex.
Size of the penis has been shown to be important in previous studies where the penis size of the same male in a picture was digitally altered; in the latest study 105 heterosexual women were shown random pictures of naked men with varying body shapes and sizes.
This showed the size of the flaccid penis was linked to other image considerations, such as the shoulder to hip size.
The research of the Australian National University in Canberra completed the study using female Australian university students with an average age of 26.
“Since penis size is a sensitive subject. It’s hard to determine whether females lied or ‘self-deceived’ in their responses,” said lead author Brian Mautz, a postdoctoral researcher in evolution and sexual selection at the University of Ottawa.
Despite the uncomfortable nature of the subject researchers claim the study is important as it could show evolution has an important role in which men are seen to be attractive to women. The study has not yet shown the average size of the male penis or “what size is best.”
“We didn’t find an ideal penis size or height,” Mautz explained. “The attractiveness scores were still increasing at the largest values for these traits.”
The study did document the ethnicity and age of the women it was studying for hints about whether penis size mattered.
More than 70 per cent of the women were of European origin, 20 per cent were Asian and seven per cent were from elsewhere. Their average age was 26.
The results “directly contradict claims that penis size is unimportant to most females,” and also hint at why human males tend to have relatively larger genitalia when compared to other primates, the study said.
“Our results show that female mate choice could have played a role in the evolution of the relatively large human male penis,” the authors wrote.
“Before clothing, the non-retractable human penis would have been conspicuous to potential mates.”
The findings were published in a peer-reviewed scientific journal in the United States, called the Proceedings of the National Academy of Sciences (PNAS).
