How do genes and hormones control puberty?
Human BiologyEndocrinology
Quick Answer
Puberty starts when the brain activates hormone signals that trigger the reproductive system and body changes. Genetics influences when this timing begins and how it unfolds.
The Full Story
Puberty begins with signals from the hypothalamus and pituitary gland, which stimulate the ovaries or testes to produce sex hormones. These hormones drive growth spurts, body hair, voice changes, and reproductive maturity. Genetic factors strongly influence the timing of puberty, although nutrition, health, and environment also play roles. Researchers have identified many genes involved, showing that puberty timing is regulated by a complex biological network.
