Which option lists two common puberty changes for boys and two for girls that health teachers should address in classroom discussions?

• A. Boys: facial hair and voice deepening; Girls: breast development and onset of menstruation.
• B. Boys: testicular growth and growth spurts; Girls: breast development and onset of menstruation.
• C. Boys: voice deepening and mood changes; Girls: mood changes and breast development.
• D. Boys: testicular growth and voice deepening; Girls: breast development and onset of menstruation.

Answer: (D)

Puberty brings distinct changes that teachers commonly address for each sex, focusing on recognizable, early markers. For boys, the first clear signs are testicular growth and a deepening voice as the voice box enlarges under testosterone. For girls, the typical early changes are breast development and the onset of menstruation, indicating reproductive maturity. This pairing highlights the most consistent, observable sex-specific puberty milestones that educators use in discussions. Other options mix in changes that are less universal or occur in both sexes (like growth spurts or mood changes) or include later-stage signs (such as facial hair), which are less ideal as the core classroom points.
