How tall can a boy grow after his voice changes?

Children usually go through three growth stages during their growth. Puberty is the best time for boys to grow. Most boys grow rapidly during puberty. If a boy's height does not grow well during puberty, it is usually difficult for him to grow after puberty. After puberty, boys have basically reached the standard of an adult. How much taller can a boy grow after his voice changes?

How tall can a boy grow after his voice changes?

Height varies from person to person. Generally, a height of about ten centimeters is normal. Normal boys enter puberty at the age of 10 to 13. The earliest signs of puberty are changes in the voice and enlargement of the testicles, followed by an increase in male hormones, the appearance of secondary sexual characteristics and accelerated growth. The average duration of a boy's entire puberty is 4.9 years, and the total height growth is about 25 to 30 cm. Among them, the middle puberty is about 1.5 years, which is a period of rapid growth, with an annual growth rate of more than 10 cm. After that, the growth rate decreases sharply until it stops growing completely.

What factors may affect height?

The early or late maturity age will affect the height growth spurt. Generally, people who have a rapid growth spurt earlier will reach the end point sooner; those who have a later growth spurt will reach the end point later. When girls with precocious puberty stop growing taller, girls with late puberty are still growing taller. Therefore, girls with late puberty are taller. The fastest growth period is prepuberty. Girls can increase their height by 7 to 8 cm in the year before menarche; boys' height growth peaks in the first year of puberty, around 13 to 14 years old, and their height can increase by 10 to 12 cm.

For boys who enter puberty, the secretion of growth hormone increases, and the rate of bone growth also accelerates. At the same time, sex hormones also begin to be secreted and increase day by day. Sex hormones can promote the accelerated maturation of the epiphyseal plate, leading to the accelerated closure of the epiphyseal line until it is completely closed and the child stops growing. These changes all occur after the voice changes or the first ejaculation.

Therefore, when a boy's voice changes, it indicates that his height begins to stop growing. He can only grow 5-7.5cm at most, and some children may only grow 1-2cm.

In life, many parents do not know much about adolescent growth and development. By the time they find that their children have growth problems, they have often missed the best time to intervene in height. Therefore, in the context of the general early sexual development of children, it is particularly important to rule out the possibility of premature development as soon as possible.

Step 1: Pay attention to your child’s growth and development

One of the best and most effective ways to rule out precocious puberty in children is for parents to observe them carefully in daily life and do regular bone age testing to understand their current growth and development status.

Step 2: Control your diet

For children to grow up healthily, they must have a balanced diet and not blindly supplement. Reduce the intake of high-calorie, high-fat foods, ensure protein intake, and eat more fruits and vegetables. At the same time, try to keep children away from foods containing additives, ripening agents, and hormones.

Step 3: Keep exercising

Cultivate good exercise habits. Exercise can not only strengthen the body, but also help consume excess calories and fat to prevent children from being overweight and inducing precocious puberty. It is recommended that children exercise for half an hour to one hour every day and adhere to the principle of moderation.

Step 4: Provide a healthy environment

Avoid children's exposure to behavioral images that exceed their psychological age and reduce psychological stimulation; reasonably control the time children spend watching TV, playing with mobile phones and other electronic devices, because excessive light and radio waves can reduce the secretion of melatonin by the pineal gland in the brain, causing the pituitary gonadotropin, which is usually inhibited by melatonin, to be secreted prematurely, leading to precocious puberty.
