Secondary sexual characters

Text Solution

Verified by Experts

Secondary sexual characters are those which help distinguish the two sexes morphologically. The appearance of these characteristics is influenced by the secretion of hormones at the onset of puberty. Testosterone and oestrogen are responsible for the production of secondary sexual characters in males and females, respectively.
Testosterone is involved in greater bone density, high muscle mass, larger voice box, beard and moustaches development, etc.
Oestrogen is involved in breast development, increased fat tissue around hips, wider pelvic bone, etc.
