Info About The Human Reproductive Cycle

Adolescence starts around age ten and runs through fifteen. The body picks up new hormones. They reshape bones and muscles, boost oil in the skin and crank up sweat glands. These shifts leave the body ready to reproduce.

Boys and girls go through many of the same shifts. Muscles thicken in boys while curves fill in faster in girls. Voices drop for males and menstrual cycles begin for females. Hair appears in new spots and extra oil often leads to breakouts.

A big height jump hits both sexes. Girls sprint ahead first then boys zoom past later. Mood swings pop up with this process. Interactive tools map each step with clear visuals and hands-on examples.
