Spermarche occurs after the growth spurt and is associated with SMR stage

• A. Stage 2
• B. Stage 3
• C. Stage 5
• D. Stage 4

Answer: (D)

Spermarche marks the point at which the male reproductive system reaches functional maturity after the initial growth spurt, so it aligns with the later stage of pubertal development. By this stage, genital development has progressed significantly—testes and penis are near their adult sizes and reproductive capacity is established. That is why the event best matches the later SMR (Tanner) stage, the one where maturation is well advanced but not yet fully at adult completion. It’s earlier than full maturation, and earlier stages reflect earlier changes, while the final stage represents complete maturity.
