What is the typical maximum age boys stop growing?

Boys generally experience their most significant growth spurts during puberty, which typically occurs between the ages of 12 and 16. The growth plates in their bones usually close by the late teenage years. While some boys may continue to grow slightly until around age 18, most complete their major growth by 16 or 17. The correct choice indicates that 17 is often cited as a typical age by which boys may finish growing, aligning with the average timeline of growth plate closure and the end of physical maturity in males. This understanding of growth patterns is essential for professionals working in exercise physiology and related fields, as it can influence training regimens and expectations during developmental years.
