## Size Matters: A Scientific Study A recent study published in PLOS Biology explored how male penis size influences the perception of attraction and threat. The research found that men with larger penises are considered more attractive to women and more intimidating to other men. ## Study Methodology The researchers recruited over 600 men and 200 women, asking them to rate computer-generated male figures with different heights, body shapes, and penis sizes (in a flaccid state). Participants rated the figures as potential mates (women) or rivals (men). The study used nondescript figures to avoid cultural biases. ## Key Findings * Women prefer figures with larger penises, V-shaped bodies, and greater height. * Men perceive figures with larger penises as more threatening rivals. * Men believe that figures with larger penises are more attractive to women. ## Evolutionary Implications The researchers suggest that, in the past, men may have avoided confrontations with rivals equipped with larger penises. This would have led to greater access to partners for men with these characteristics, contributing to the evolution of human penis size. ## Next Steps The researchers intend to study how these visual cues interact with other factors, such as facial features and voice. It will also be interesting to assess how these perceptions vary across different cultures. ## General context Sexual selection is an evolutionary process in which certain traits that enhance reproductive success become more pronounced over time. These traits can be selected by females (intersexual selection) or associated with greater success against male rivals (intrasexual selection).
