Boys continue growing until age 17 or 18. Boys and girls grow about two inches per year until they reach puberty. Then they each have a growth spurt that lasts a year or two. During the growth spurts, boys grow a little faster than girls. Girls reach puberty (on average) about a year before boys do. Girls also end puberty earlier than boys.
The pubertal growth spurt is a rapid increase in height and weight, usually occurring at age 10-12 in the. girls and 12-14 in boys. When the growth spurt is delayed, as in CDGP, the peak growth rate of the. growth spurt is reduced. Also, boys with this condition tend to progress through puberty more slowly.
