Which gender tends to have growth spurts earlier?

• A. Boys
• B. Girls
• C. Both equally
• D. Neither

Answer: (B)

Growth spurts begin earlier in girls because puberty typically starts sooner for them than for boys. Estrogen drives the pubertal growth spurt, and girls usually enter puberty around ages 8–13, with the growth spurt occurring early in that period. Boys generally start puberty later, around ages 9–14, and their peak growth occurs a bit later. So, in terms of timing, girls tend to have their growth spurts earlier.
