When do boys grow beards?

People from different regions, climates, and races go through puberty at different times. For example, children in tropical Africa go through puberty earlier than children in Asia. Generally speaking, Chinese boys begin to grow and develop their bodies and beards at the age of 14 to 15. Growing a beard is a secondary sexual characteristic of men. This is because the testicles of boys begin to metabolize testosterone after entering puberty, which stimulates the growth of beards. As the testicles gradually grow and develop, and begin to have the ability to produce sperm and testosterone, children gradually grow and develop into adults.

Boys usually reach puberty, around 17 or 18 years old. Some boys who grow and develop earlier will grow beards. Some boys who grow and develop more slowly will grow beards around 18 or 19 years old. This is all normal. Beard growth is related to one's own growth hormone. For some boys with sufficient growth hormone metabolism, beards will grow and develop earlier. It is best not to eat spicy and irritating foods, and try to avoid eating fried waste foods. Drink plenty of water to replenish the body's water. Try to avoid using electronic devices with radiation sources.

Boys' development is normal unless it is earlier than 9 years old. The first symptom is the change of voice. Generally, the voice of children under 10 years old becomes sharper and sharper, and then a little coarse. The height also grows faster. The scrotum will continue to expand, and the change of hair will become more obvious. At about 11 to 12 years old, short and sparse pubic hair will grow on the vulva. At about 12 years old, the Adam's apple in the neck begins to be prominent, and the voice becomes louder and coarser. This stage is called the change of voice. At 13 to 14 years old, armpit hair begins to grow and facial beard begins to grow.

The normal growth and development of boys is at the age of 13 or more. The testicles begin to expand, the penis thickens, and the secondary sexual characteristics begin to develop. This is the normal growth and development age and level. If the testicles expand, the penis thickens, and the secondary sexual characteristics develop before the age of 9 or 9.5 years, it is clinically called precocious puberty. If the growth and development occurs between the ages of 9 or 9 years and a half and between the ages of 13 and more, it is called early sexual development. Early sexual development will cause the child to be shorter than the average adult, or the probability of estrogen-related symptoms is higher. Therefore, once growth and development are premature, it is necessary to actively go to the hospital outpatient clinic to measure bone age and test related female hormones such as children's growth hormone and estrogen, and further provide treatment and intervention based on the specific severity.
