Precocious and premature development in children should be a cause for concern for parents.

2026-05-13

Precociousness and premature maturity in young people should be guarded against.

A father, noticing his son's premature maturity, decided to provide him with early sex education. He found it difficult to talk to his child about such matters, but out of concern for his son, he mustered the courage to do so.

"Son, Dad wants to talk to you."

"What are you talking about, Dad?"

"Oh, it's nothing really, just a question about 'sex'." The father's face turned red, and he stammered as he spoke.

The son, noticing his father's unusual expression, asked with concern, "It's okay, relax. What do you want to know?"

This lame joke points to a serious problem in today's society-precocious puberty. Generally, precocious puberty refers to physical precocity. However, children today are not only prone to physical precocity but also psychological precocity. Physical precocious puberty manifests as the premature appearance of secondary sexual characteristics, such as pubic and armpit hair, rapid growth in height and weight, and the development of external genitalia.

Two-year-old Junjun's growth and development were unusually rapid from birth. By six months old, he had developed acne on his face, his voice had deepened, and his testicles and penis had noticeably enlarged, making him prone to erections. He also became quite irritable. His parents took him to the hospital for a checkup.

Based on Junjun's clinical presentation and an MRI scan, the doctor diagnosed him with a hypothalamic hamartoma. International literature suggests a high rate of hypothalamic hamartomas in infants, especially children under 3 years old, who are experiencing precocious puberty. Parents should be highly vigilant and undergo MRI to rule out this disease should any signs of precocious puberty be observed.

The doctor explained in detail to Junjun's mother: Precocious puberty is the appearance of sexual maturity symptoms in males before the legal age of sexual maturity. The hallmarks of male sexual maturity are the development of adult-type male genitalia and the appearance of secondary sexual characteristics, such as enlarged testicles and scrotum, increased penis length and girth, the appearance of pubic hair, beard, armpit hair, a deepening and lowering voice, a larger Adam's apple, increased height, and even penile erection and ejaculation. Boys exhibiting these characteristics before the age of 10 can be diagnosed with precocious puberty. Normal activity of the thalamus-pituitary-gonadal axis promotes the normal development of sexual organs and the perfection of sexual function. If certain factors affect the normal activity of this axis, it may disrupt the natural progression of sexual development, resulting in precocious or delayed puberty.

Some cases of precocious puberty are caused by tumors in the body. These tumors can secrete substances similar to sex hormones. Sometimes, even when the tumor is still small, the amount of sex hormones it secretes is already large enough to cause sexual development. Therefore, children with precocious puberty must see a doctor in time for diagnosis and treatment as early as possible.

Children with idiopathic precocious puberty experience accelerated physical growth due to the influence of sex hormones, premature fusion of the sacrum and bones, a shortened growth period, and early cessation of growth, resulting in a final adult height that is lower than that of children of the same age who develop normally during puberty.

Although children with precocious puberty develop sexual characteristics earlier than expected, their psychological and intellectual development remains at the level appropriate for their actual age. The premature appearance of sexual characteristics and the development of reproductive organs can lead to psychological problems in immature children, cause many inconveniences in their lives, and in severe cases, even affect their studies.

Precocious puberty is divided into two types: true and false. True precocious puberty involves the premature maturation of both internal and external genitalia, also known as "complete precocious puberty." Children with this condition follow a normal sexual development process and are fertile. Children with false precocious puberty, however, are not fertile and only exhibit secondary sexual characteristics. False precocious puberty can resolve on its own. If it is not caused by a disease, most children do not require special intervention; simply removing the cause of precocious puberty will gradually lead to a return to normal. However, some cases may develop into true precocious puberty. If you notice your child's sexual characteristics continuing to develop, you should seek medical attention as soon as possible. Specifically, precocious puberty can be divided into the following categories:

1. Cerebral type true precocious puberty: caused by factors such as skull base fracture, severe birth injury, small hypothalamic tumor, recovery from tuberculous meningitis, and sequelae of measles encephalitis.

2. Constitutional precocious puberty: Many children with this condition have a family history of the condition. It is caused by premature activity of the hypothalamus-pituitary-sexual axis and is also known as unexplained precocious puberty.

3. Pseudoprecocious puberty: Conditions such as adrenal cortex enlargement, adrenal cortical tumors, functional gonadal tumors, choriocarcinoma, and embryonic tissue tumors can cause precocious puberty because the lesions and tumors themselves can secrete sex hormones or gonadotropins, leading to the development of sex organs. Another example is exogenous precocious puberty caused by a child accidentally ingesting their mother's birth control pills. If precocious puberty is suspected in a boy, he should be examined at a hospital promptly, as boys are much more likely to have tumors associated with precocious puberty than girls, so this should not be taken lightly.

In addition to examination and treatment, parents should pay special attention to their child's psychological changes. After a clear diagnosis, they should explain necessary information to their child to help them adapt to the new changes in their body. Parents should also be prepared that some cases of precocious puberty lack effective treatments, requiring even more careful parental care. Currently, some children's nutritional supplements on the market contain hormones, and excessive consumption can lead to precocious puberty; parents should be aware of this.

The fast pace of modern life and the increasing diversity of food have brought many benefits to humankind. However, some foods now contain artificial additives, preservatives, ripening agents, and flavor enhancers. While this allows us to enjoy watermelons and grapes in the dead of winter and summer or autumn fruits in spring, it also brings significant potential harms. Vegetables, an essential part of daily life, are now available out of season in markets, but the large amounts of pesticide residues, industrial fertilizers, and growth hormones do not truly make consumers healthy. Instead, they contribute to increased rates of diabetes, high cholesterol, birth defects, and cancer, with even greater impacts on infants and children. Chickens, ducks, pigs, and freshwater fish raised on feed and additives for rapid growth contain undigested and excreted precocious hormones in their meat. When parents, hoping their children will succeed, feed them fried chicken or other meat products, these hormones have already begun to accumulate in the child's body, accelerating precocious puberty.

In general, the causes of precocious puberty in children include the following:

1. Illness: Some metabolic and endocrine disorders can cause precocious puberty in children, along with other symptoms. Parents should take their children to see a doctor as soon as possible if they notice these symptoms.

2. Environmental Pollution: If poultry are contaminated with hormones during animal farming, meat, eggs, and dairy products may contain hormones, potentially leading to precocious puberty. In addition, the effects of hormone-like pollutants in the environment, such as detergents, pesticides, and plastic products, can also cause precocious puberty. These substances, after decomposition in the atmosphere, can produce estrogen-like active substances. If children come into contact with these substances through skin contact or accidentally ingest them, it can also lead to precocious puberty. Parents need to be vigilant.

3. Abuse of health supplements: If parents always hope their children will grow taller, stronger, and less prone to illness, blindly giving them excessive amounts of health supplements can also lead to precocious puberty. Examples include animal colostrum, silkworm pupae, and royal jelly.

4. Sociopsychological factors: Sexually related images in the media, excessive intimacy between parents, and other such exposure can stimulate the endocrine system, causing children to enter puberty earlier than expected. Therefore, parents should be mindful of their behavior in front of their children.

However, currently, most cases of precocious puberty in children are pseudoprecocious puberty, meaning that some sexual characteristics appear early, but sexual function has not truly matured. Pseudoprecocious puberty is often caused by inappropriate exposure to exogenous sex hormones or preparations containing sex hormones, and is frequently related to obesity, long-term indiscriminate use of health supplements and tonics, etc. Some meat, poultry, and egg products are treated with hormones by producers to increase production or promote early maturation; long-term consumption of such foods can also cause precocious puberty.

Therefore, prevention is key in managing precocious puberty in children. Some nutritional supplements contain substances similar to sex hormones, such as popular children's multivitamins, which contain substances that can induce precocious puberty. Commonly used tonics, such as American ginseng and propolis, are rich in hormones. Many parents give their children tonics on their own after they fall ill, but children generally recover quickly from illnesses, unless it's a chronic condition. Therefore, tonics are generally unnecessary. Parents only need to ensure their children have a balanced diet of three meals a day, avoiding excessive consumption of high-calorie foods such as high-sugar, high-fat, and high-protein foods. Secondly, long-term use of nutritional supplements should be avoided, especially those containing pollen, royal jelly, or ginseng. Children should also avoid foods containing hormones, such as silkworm pupae. Reduce meat consumption and increase seafood, vegetables, fruits, and whole grains to ensure a balanced diet.
