Growth and Puberty in detail

Puberty is the stage when the body becomes capable of reproduction, usually between ages 10 and 16, triggered by hormones. In males, testosterone from the testes causes a deeper voice, facial hair, muscle development and sperm production. In females, oestrogen from the ovaries causes breast development, wider hips and the start of periods.

Growth involves cell division and enlargement, and in humans there are fast growth phases in infancy and puberty. Growth is measured with height and mass charts, which show whether a child's growth is typical. Emotional changes also occur during adolescence.
