At what age does the pubertal growth spurt peak in males?

• A. 12 years
• B. 16 years
• C. 18 years
• D. 14 years

Answer: (D)

In boys, the rapid growth spurt occurs later and reaches its fastest pace during mid-adolescence. The peak height velocity—the fastest rate of height increase—usually happens around 13 to 14 years old. This is when the body is riding the height of pubertal hormonal changes (testosterone with growth hormone/IGF-1) before growth tapers off as the growth plates gradually fuse. So, about 14 years is the best fit because it sits in the typical window when height increases fastest. Some boys hit their peak a little earlier or later, but by 18 most have finished growing, and at 12 years the velocity is usually still increasing rather than peaking.
