What finding defines precocious puberty in boys?

• A. Penile enlargement before age 9
• B. Delated testicular enlargement
• C. Absence of pubertal signs
• D. Early growth with no pubertal signs

Answer: (A)

In boys, precocious puberty is defined by pubertal development before age 9. Penile enlargement before age 9 specifically signals androgen-driven pubertal progression occurring early, so it serves as a clear manifestation of precocious puberty and is the best choice among the options. Delayed testicular enlargement would indicate late or absent puberty, absence of pubertal signs means no pubertal development yet, and early growth without pubertal signs suggests accelerated growth without gonadal maturation.
