Which statement describes Tanner Stage 1 in males?

• A. No genital hair and a childhood-appearing penis
• B. Enlarging testes with sparse hair
• C. Penis grows substantially
• D. Adult pubic hair

Answer: (A)

Tanner Stage 1 in males represents the prepubertal state. At this stage, there is no pubic hair and the genitalia look like they did in childhood—the penis is not enlarged and the testes are not yet increasing in size. The statement describing no genital hair and a childhood-appearing penis matches this prepubertal condition exactly. As puberty progresses, you’d expect the testes to enlarge and pubic hair to appear, followed by further growth of the penis and eventual development of adult-like pubic hair. The other descriptions point to later stages of pubertal development, not to Stage 1.
