secondary sexual characteristics - Click to enlarge

Click image to enlarge

Stage in human development when the individual becomes sexually mature. It may occur from the age of ten upwards, but each person is individual. The sexual organs take on their adult form and pubic hair grows. In girls, menstruation begins, and the breasts develop; in boys, the voice breaks and becomes deeper, and facial hair develops. Both boys and girls will experience emotional as well as physical changes.
