At SMR stage 2, what is the expected testicular volume?

• A. 4 mL
• B. 10 mL
• C. 12 mL
• D. 15 mL

Answer: (A)

During early puberty, testicular growth is the first sign of maturation. At SMR stage 2, the testes have begun to enlarge from their prepubertal size to about 4 mL. This level sits at the beginning of pubertal enlargement, whereas higher volumes (around 8–12 mL, 12–15 mL, and 15 mL+) correspond to later stages. So 4 mL best fits stage 2, reflecting the initial pubertal growth of the testes.
