Which statement describes SMR stage 4 in male development?

• A. Pubic hair looks adult but less of it, coarse and curly
• B. Pubic hair resembles stage 3
• C. Pubic hair absent
• D. Growth spurt occurs here

Answer: (A)

Understanding SMR stage 4 in male puberty centers on how pubic hair changes. At this stage the hair has the appearance of adult hair—coarse and curly—but its distribution is not yet the full adult pattern; it’s more limited in how far it extends. That’s why the description “pubic hair looks adult but less of it, coarse and curly” fits best. Earlier stages show finer, lighter hair and smaller coverage, and the absence of pubic hair signals a prepubertal phase. Growth spurts are a general part of puberty and aren’t the defining feature of this stage, whereas the key change here is the maturation of hair texture with limited spread.
