Average Age Of Growth Spurts In Boys. The average age at which puberty begins in boys is 11 to 12 years. The end of puberty is not clearly delineated and may vary with the physical, emotional, mental, social and cultural criteria to define an adult boy. However, it usually gets complete at around the age of 17 to 18.
The average growth velocity by age 6 falls to (2 or so inches (5.0-5Â·5 cm) per year, with minimum sex differences in the growth rate until the onset of puberty. The growth spurt at puberty is fueled by the secretion of growth hormone and sex steroids. The timing of this growth spurt is extremely variable.f sustained, it would provide 50-60 cm (close to 2 feet) of growth per year. This extraordinary rate of growth is largely independent of growth hormone. Growth hormone only begins to play a role in growth in the final weeks before birth.
