How do hormones control puberty?
Quick Answer
Puberty begins when the brain and endocrine glands start releasing hormones that trigger physical changes like growth, body hair, and reproductive maturity. The process usually begins between ages 8 and 13 in girls and 9 and 14 in boys.
The Full Story
Puberty starts when the hypothalamus signals the pituitary gland to release hormones that activate the ovaries or testes. These organs then produce sex hormones such as oestrogen and testosterone, which drive changes in the body. Growth spurts, changes in body shape, voice changes, and development of secondary sex characteristics all follow from this hormonal cascade. The timing varies naturally from person to person and can be influenced by genetics, nutrition, and overall health. Puberty marks the transition from childhood to reproductive maturity.
