In boys, puberty brings a sequence of hormone-driven physical developments, mainly influenced by testosterone.
Typical changes include:
- Growth spurt
Rapid increase in height and muscle mass.
- Voice deepening
The voice becomes heavier as the larynx (voice box) enlarges.
- Development of facial and body hair
Hair begins to grow on the face, chest, underarms, and pubic region.
- Broadening of shoulders
Body structure becomes more muscular and angular.
- Maturation of reproductive organs
The testes and penis grow, and sperm production begins.
- Skin changes
Increased oil secretion may lead to acne.
- Increased sweating and body odor
Due to more active sweat glands.
Important point:
These changes occur at different rates for each individual and are a normal part of development.
