A new study from the University of Iowa Department of Orthodontics reveals that males have larger noses than females to facilitate the intake of more oxygen for more lean muscle mass.
A study from the University of Iowa Department of Orthodontics looked at why the average male nose is 10% larger than a female’s. Observations during the study showed the nose size became different between men and women during puberty as young boys are gaining more lean muscle mass. With this muscle mass comes a need for more oxygen. Therefore a larger snout isnecessary.
