Question:
Hello Sir,
I have a question about the tempo, the timing, and the speed of height growth, maturity stages, and overall development.
I am a 19-year-old boy and have already entered Tanner stage 5. My pubic hair started to grow somewhere between ages 13 and 14; hair on my legs and arms started between ages 14 and 15; my voice started to change at age 14; and I reached a mature voice around age 16. By age 15, I had some hair on my moustache, while hair on my chin and sideburns began to grow by age 16. Now I almost have a full beard, though it is still a little patchy on my cheeks. By age 17, hair on my chest and abs started to grow. To me, it seems like a normal rate of pubertal development.
However, I did not observe a noticeable peak in height growth. At age 10, I was around 55 inches tall; at age 14, I was 63/64; at age 15, I was 66; at age 16, I was 68/69; at age 17, I was 69.7; at age 18, I was 70.5, and now I am 71 inches tall.
Is it possible for a boy not to have a massive growth spurt? In this case, would the peak of the growth rate be lower?
Thanks
Answer:
Not everyone has a huge growth spurt. Generally, those with a high rate of growth experience it for a shorter period, while those with a lower rate of growth experience it for a longer period. You had a faster rate of growth between the ages of 14 and 16, growing 3 inches each year. Sometime during your 16th year, you entered stage 4, and your growth slowed down. At 19, you reached stage 5. Therefore, you have spent about 2 years in stage 3 and 2 years in stage 4, which is typical.
Despite the slower peak rate of growth, you are taller than average because you started about 1-2 years later than most boys. That delay caused you to start from a greater height because you were still growing at a childhood rate.
