Hormones - What are they and what do they do?
Hormones are naturally occurring chemicals in the body which help to control the way we feel and function.
For example, as you approach puberty, the brain and pituitary gland release hormones that affect the sexual organs of both males and females. These hormones are estrogen, progesterone and testosterone. These hormones can be found in females and males, but in differing amounts. Estrogen and progesterone are more prominent in women and responsible for the development of female sex characteristics and reproductive functions, and testosterone is found in greater amounts in men and is responsible for the development of male sex characteristics.
Growth hormones are also released at this time, which makes the body grow larger. This major growth surge can last for several years, and when it is over, you will have usually reached your adult height.
Hormones are also responsible for the emotional changes that take place during puberty.
