In males, which changes characterize Tanner Stage 2?

• A. Few straight pubic hairs and thinning, reddening scrotal skin
• B. Penis lengthens and testes enlarge
• C. Penis grows in length and width, and the glans enlarges
• D. Adult genitalia and pubic hair extending toward the umbilicus

Answer: (A)

In male puberty, Tanner stage II is the first sign of puberty and centers on early changes in the testes and pubic hair. At this stage, the testes enlarge and the scrotal skin becomes thinner, redder, and textured. Pubic hair begins to appear as a few long, straight hairs at the base of the penis. The penis itself has not yet grown noticeably, so descriptions of lengthening or widening don’t apply yet. The other descriptions reflect later stages where penile growth or more extensive pubic hair development occurs, or where the genitalia resemble adult form.
