It was found that the increase in muscle mass, which begins in boys at the age of 11, provokes the beginning of active growth of the nose, whereas the girls are not observed to have such a process.
The research conducted by the University of Iowa showed that the size of men’s noses is directly related to the demand for oxygen, which is much higher in men than in women.
This relationship, according to the scientists, is caused by men’s muscle mass, which is bigger than in women and requires more energy and oxygen.
In addition, there is a link between the growth of the nose and puberty. The researchers found that boys demonstrate a significant increase in muscle mass and the size of their nose. In girls, this process is not observed.
