Physical Changes at Puberty
During puberty, the body changes and becomes sexually mature and able to reproduce. The primary sex characteristics mature, and the secondary sex characteristics become more distinct. Primary sex characteristics are related to reproductive organs. The reproductive organs, present at birth, begin to function differently at puberty. For instance, the testes and ovaries are involved in stimulating more visible changes, such as breast development and growth of the penis.
