In SMR stage 4, testes are approximately how many milliliters?

• A. 4 mL
• B. 8 mL
• C. 12 mL
• D. 16 mL

Answer: (C)

SMR stages use testicular size as a practical clue to where a boy is in puberty. In stage four, the testes have grown from their prepubertal size and reach a moderate, mid-pubertal size—not the smallest and not yet fully adult. This mid-range size reflects puberty advancing beyond the earliest changes but not yet at full mature dimensions. The other options represent either smaller volumes seen earlier in puberty or larger volumes closer to adulthood, so the value that best matches stage four is the mid-range one.
