Most boys continue to grow until their later teen years, but some experience noticeable growth spurts along the way. Growth spurts are often related to the onset of puberty, so boys frequently have height increases as they experience hormonal changes. Growth spurts are also genetic, so some boys might be slow, steady bloomers while others shoot up rapidly during their early teen years and level off over time.
Summer and Nighttime Sky Rockets
There's no exact science for predicting growth spurts in boys but studies show that certain seasons and times of the day are relevant factors. According to Joseph Gigante, associate professor of pediatrics at Vanderbilt Children's Hospital, both girls and boys grow fastest in the summer and slowest in the fall, as reported in "Parenting" magazine. In addition, the human growth hormone is produced throughout the day in children, preteens and teenagers, but is released in large doses during sleep. As a result, some growth spurts in boys are most obvious in the summer when they get good amounts of rest and plenty of physical activity.
Puberty at Last
Many boys experience a drastic change in height shortly after puberty begins. According to KidsHealth.org, boys often grow most rapidly between the ages of 12 and 15. Some boys show early signs of puberty around age 10, but growth spurts usually start a year or two later. Not all boys experience noticeable, acute growth spurts and may grow at a steady rate. Genetic factors, eating habits, exercise, sleep and overall health play important roles in a boy's height increases.
Boys and girls often experience growth spurts at different ages. The average growth spurt for a boy occurs 2 years later than a similar spurt in girls. Because girls often enter puberty earlier than boys, they might experience a growth spurt as early as age 10 but completely stop growing around age 15. Boys on the other hand might not experience a growth spurt until age 12, but often continue growing until age 17, according to "Parenting" magazine. Some teen boys might even experience small height increases as they enter adulthood.
Preteen and teen boys often feel self-conscious if they aren't as tall as their peers or they experience growth spurts later than their friends. As a result, they might develop a poor self-image and consider height-inducing supplements or steroids. Encourage your son to talk to his doctor or pediatrician about any health-related concerns or anxieties, recommend the experts at KidsHealth.org. Doctors offer professional advice and will likely reassure your child that his height falls within normal ranges. They can also detail the harmful side effects of steroids and other growth-related drugs.
