An Australian study led by Dr. Brian Mautz and Professor Michael Jennions from the Australian National University examined the role of body and genital size in perceived male attractiveness. This research used computer-generated, life-sized male figures with varying height, torso shape, and penis size to gauge how these features impacted attractiveness ratings by women. The study, published in the *Proceedings of the National Academy of Sciences*, found that while torso shape (broad shoulders and narrow waist) was the strongest predictor of attractiveness, both height and penis size played a significant role as well.
Notably, penis size impacted attractiveness on a level similar to height, which was already known to be important. Interestingly, the effect of a larger size was more positive for taller men compared to shorter men, suggesting that the appeal of larger size is not straightforwardly “bigger is better,” but is contextual. The research also highlighted how quickly participants made judgments, often within seconds, indicating an instinctive overall impression rather than detailed analysis of individual features.
This study provides valuable insight into human sexual selection and how physical traits contribute to attractiveness, challenging some common assumptions about the importance of individual attributes in isolation. The findings point toward a complex interaction of factors that influence initial attraction, emphasizing that no single trait defines attractiveness in a straightforward manner.
