In humans, the gametes are usually produced in different sexes (male and female). These sexes often show outwardly differentiating features called secondary sexual characters. Secondary sexual characters throughout the animal world serve to identify and attract sex partners. Odours (body smells), calling sounds, skin colouration, body contours, behavioral patterns, etc. are some such sex clues.

In humans, the secondary sexual characteristics include:
(i) Distribution of hair on body and face (beard and moustaches in males).
(ii) Breasts in females.
(iii) Muscularity - stronger built in males.
(iv) Skeletal structure.
(v) Behaviour.
(vi) Deeper voice in males.
