Puberty typically begins for boys in which age range?

• A. Approximately 7–9 years
• B. Approximately 13–16 years
• C. Approximately 11–14 years
• D. Approximately 9–11 years

Answer: (C)

Puberty in boys typically begins in early adolescence, with the first sign usually being testicular enlargement, followed by other changes such as growth of pubic hair, a growth spurt, voice deepening, and later spermarche. While there is variation, the average onset is around 11–12 years, though some start as early as about 9 and others as late as about 14. The best choice among the options is approximately 11–14 years because it captures the common onset window for most boys. The other ranges are either earlier than most begin (7–9), later than typical onset for many (13–16), or too narrow to include the common early teen start (9–11).
