Name two physical changes during puberty in males and two in females.

• A. Males—pubic hair growth and voice deepening; Females—hips narrowing and early menopause.
• B. Males—testicular growth and spermarche; facial/body hair growth; Females—breast development and menarche; hip widening.
• C. Males—breast development and menarche; Females—sperm production; voice deepening.
• D. Males—none; Females—breast development only.

Answer: (B)

Puberty brings hormonal changes that drive the development of secondary sexual characteristics and the ability to reproduce. For males, two key physical changes are testicular growth, which signals the onset of puberty, and spermarche, the first ejaculation indicating the start of sperm production. Facial and body hair growth is another common change that occurs as testosterone rises.

For females, two important changes are breast development and menarche, the first menstrual period, which signals reproductive capability. Hip widening also occurs as the pelvis changes to prepare for potential childbirth.

The best choice reflects these typical male changes (testicular growth and spermarche) and female changes (breast development and menarche, with hip widening as another common change). Other options mix changes that don’t align with puberty patterns (such as hips narrowing or early menopause, or mismatching which sex experiences certain changes).
