To begin with, we can say that the secondary sexual character is what, in a species, differentiates the male from the female, without this characteristic being directly linked to reproduction.

Among animals, here are some examples: lion’s mane, deer antlers, ram’s horns…

In human hope, certain secondary sexual characteristics are well known: the hairiness is often greater in men, the pelvis wider in women

Others are more amazing! without being systematic, we note however that often the difference in size between the index and middle fingers is more marked in women than in men. In the same way, often, the woman can keep the stretched arms and the glued elbows when the man, him, is incapable of it! Take the test!
