Which body system's hormones drive puberty?

• A. Nervous System
• B. Endocrine System
• C. Immune System
• D. Digestive System

Answer: (B)

Puberty is driven by hormonal signals from the endocrine system. The brain signals the pituitary to release hormones that stimulate the gonads (testes or ovaries) to produce sex hormones like testosterone and estrogen. These hormones trigger the physical and sexual changes of puberty, such as growth of body hair, breast development, and voice changes. While the nervous system helps initiate the process by sending signals, the actual drivers are the endocrine glands releasing hormones. The immune and digestive systems don’t produce the puberty-driving hormones.
