According to a new report, men have bigger nose than women. Researchers at University of Iowa said that men have bigger nose than women because of their lean muscle mass.

Researchers said that big nose is used to inhale more oxygen that can be carried into the blood of men. More oxygen is inhaled by men to supply the fibrous tissues in the nose. Researchers found that men and women sniff differently at their age of puberty. This happens because men start growing lean muscles and women with fat mass.

Nathan Holton, assistant Prof. at university's College of Dentistry, said that this study has been lead for the first time in the field of medical science. He said that size of nose has been used for the first time to link the size of body in males and females.

Scientists revealed that male exhibit unequal increase in the nasal size along with an increase in the size of the body. "This follows the same pattern as energetic variables such as oxygenate consumption, basal metabolic rate and daily energy requirements during growth", said scientists.

Holton said that size of male nose is always bigger than that of female, even if their body size is same.
