Does size really matter?

  • A new PLOS Biology study by Upama Aich and colleagues found penis size influences perceived female attractiveness and male assessments of fighting ability, based on ratings from over 800 adult participants.
  • Driven by long-standing debates in evolutionary biology, the research team at the University of Western Australia tested if the human penis is a badge of status or a sexual ornament, as prior work mainly focused on female choice and unusual human penile size.
  • The team produced 343 computer-generated male figures varying three traits with seven values, shown as 30° rotating video clips in two formats to about 200 females and 600 males.
  • Female participants rated taller, more V-shaped men with larger penises as more attractive, while male participants viewed rivals with larger penises as more threatening and sexually competitive.
  • Future work could examine how flaccid penis models interact with facial features, voice, movement, and cultural variation, as authors caution real-world assessments need broader integration, Dr. Upama Aich and Professor Michael Jennions say.
