Why don't you grow a beard?

When men start to secrete male hormones, secondary sexual characteristics will appear, such as beards growing above the lips and on the chin. As the number of shaving increases, the beard will not only become very hard, but also very long, so it is necessary to shave every day. However, in life, some men seem to be special, just like women, without beards. What is going on?

Beards are a manifestation of male secondary sexual characteristics. The appearance of secondary sexual characteristics is stimulated by the testosterone secreted by the testicles after a man enters puberty. Before the age of 11, there is very little testosterone in boys' bodies, and the physical characteristics between boys and girls are not very different. There is no strict time limit for boys' puberty development, which is generally between 10 and 14 years old.

After entering puberty, the first physical sign is the enlargement of the testicles and scrotum. As the testicles gradually develop and mature, they begin to have the ability to produce sperm and testosterone. Under the action of androgens, male genitals develop rapidly, and secondary sexual characteristics appear, such as a strong body, well-developed muscles, broad shoulders and small hips, facial beards, a prominent Adam's apple, and a deep voice. Men's beards are the result of androgens. The appearance and shaping of men's beards also have a process. Only when the puberty period is over and sexual maturity is reached, and the androgen in the male body reaches the level of normal adults, will the beards increase to the appearance of adults.

The level of testosterone in healthy men is generally the same, but the size of beards varies greatly. Some men have thick beards, some have thin beards; some have sideburns, some have goatees, and these are all normal differences. The size and shape of beards are related to ethnicity and family genetics. This is normal and there is no need to worry about it.

Whether it is pathological for a man to be beardless should be judged in relation to the overall development of the body. If a man has no beard, but his reproductive organs and the secondary sexual characteristics mentioned above are all developed normally, then it is not pathological. The age at which boys start to grow beards is not exactly the same. Some grow a few years earlier, and some grow a few years later. It is all normal and there is no need to worry. If a man has entered puberty and has not grown a beard, and his secondary sexual characteristics are not obvious, or even have not developed after puberty, this should be considered abnormal. It may be that there is a problem with the gonadotropin that specifically regulates and controls the secretion of sex hormones, and he needs to go to the hospital for examination and treatment.

To know whether it is a pathological sign for men not to grow beards, you actually need to consider it from all aspects. You need to understand the health status of various parts of your body and your body development. Only in this way can you find out the reasons and make correct and effective judgments to avoid adverse effects on men's health.
