What are the effects of hormonal changes during puberty?

• A. Physical development, sexual maturation, and changes in body composition.
• B. No physical changes occur.
• C. Hormones only affect mood with no physical changes.
• D. Growth slows down to complete.

Answer: (A)

Hormonal changes during puberty drive a wide range of physical and sexual developments, not just mood shifts. The rise of sex hormones—estrogen and progesterone in typical female development, and testosterone in typical male development—along with growth hormone causes a growth spurt, the maturation of reproductive organs, and the appearance of secondary sexual characteristics. These hormones also influence body composition, leading to differences in fat distribution and muscle mass (for example, more muscle growth in boys and more fat distribution in girls), as well as changes like facial and body hair, voice changes in boys, and breast development in girls. Because puberty involves tangible physical changes in shape, function, and appearance, the best description is physical development, sexual maturation, and changes in body composition. The other statements miss these broad physical effects or mischaracterize growth timing during adolescence.
