adolescent age group

China generally refers to 11-17 years old.

2. Physiological changes in male puberty

(1) Height and weight increase rapidly. During adolescence, the height can increase by an average of 9 centimeters and the weight can increase by 8 to 9 kilograms per year.

(2) The functions of various organs in the body gradually mature, so the thinking ability is active and the ability to respond to things is improved; the thirst for knowledge is strong, and various fine movements can be performed more accurately and coordinated; the reasoning and analysis ability and memory are strengthened. In addition, the development of the hypothalamus, pituitary gland, thyroid, adrenal glands, etc. and the secretion of various hormones further promote the rapid development of body tissues.

(3) The endocrine system is mature and fully functional, and the adrenal glands begin to secrete androgens. Stimulates hair growth, resulting in pubic and armpit hair.

(4) The reproductive system matures, sex hormones reach the whole body through blood circulation, the internal and external sex organs mature, and secondary sexual characteristics appear.

(5) Nocturnal emission

Nocturnal emission is a physiological phenomenon unique to men and an important sign of pubertal development.

The average age of first nocturnal emission is 14 to 16 years old, which is about 2 years later than the average age of menarche in girls. The first nocturnal emission usually occurs in summer. There may not be mature sperm in the early semen. After the first nocturnal emission, physical development gradually slows down, while the testicles, epididymis and penis develop rapidly, approaching adult levels.

Specific manifestations of secondary sexual characteristics

1. Hair (pubic hair, armpit hair and beard) growth: Pubic hair appears first, followed by armpit hair. One year after the appearance of armpit hair, a beard will grow.

2. Change your voice.

3. The appearance of Adam's apple: The protrusion of Adam's apple is a secondary sexual characteristic unique to men.

3. Psychological changes in adolescence

1. Changes in emotional development during adolescence:

Junior high school students are rich in emotions and often express clear reactions to things around them, such as enthusiastic support, envy, joy, sadness, etc. The performance is strong but unstable, and the mood is high and low, hot and cold. When something succeeds, one becomes excited; when something fails, one becomes depressed, depressed and discouraged. Emotional changes are often affected by one's own state of mind. If you are in a good mood, a very ordinary thing can make you happy;

I am in a bad mood, and even something worth being happy makes me unhappy. This is one of the hallmarks that distinguishes it from childhood emotions.

2. Enhanced personality and rapid development of independent consciousness

In terms of learning, he likes to think independently and is no longer satisfied with ready-made conclusions in books and teachers’ explanations. He likes to make new explorations and attempts. This is good for young people to increase their knowledge, develop their talents, and gain a broader understanding of the things around them.

They often have a sense of adulthood in their behavior. They hate others treating them as children. They no longer want to accept special care from their parents in life. They don't like their parents intervening in their activities. They even have psychological resistance to getting rid of their parents' supervision. However, it should be noted that after all, teenagers have little experience in the world, little experience, and poor social adaptability. They should discuss important matters with their parents, teachers, etc.

While improving their evaluation ability, they often overestimate themselves. Especially when they make mistakes and are criticized, they often develop strong feelings of resistance.

3. The emergence of sexual consciousness:

Students who are in the period of puberty and development begin to have a vague understanding of the relationship between the sexes, and in their relationship with classmates, they begin to shift from a preference for the same sex to a preference for the opposite sex. This is a normal psychological change. Generally speaking, women show affection earlier than men of the same age, and begin to love beauty, dress up, and pursue fashion. Men, on the other hand, like social activities, show off their masculinity in front of the opposite sex, and show their talents and bravery.

4. Common problems and self-care in adolescence

wet dream

Men ejaculate during sleep due to dreams. Wet dreams are a normal phenomenon, and although they may stain your clothes, there is no need to worry. However, because nocturnal emissions are often accompanied by waking up from a dream, the mind is relatively nervous and can easily cause psychological burden. Symptoms such as insomnia, headache, dizziness, listlessness, poor appetite, fatigue and weakness may occur. If this happens, you must not be burdened with your thoughts. You should participate in more cultural and sports activities, adjust your life regularly, disperse your energy, build up confidence, and be able to heal yourself. Otherwise, you should go to a doctor for treatment.

Pay attention to nocturnal emission hygiene

Nocturnal emissions cause a large amount of semen to be discharged from the body through the erect penis, which inevitably "contaminates" the underwear. It often makes people at a loss, unable to touch and unable to discard it, especially in dormitories, which is even more embarrassing.

In this case, it is best to put some toilet paper on the bed in advance and wipe it in time. If you ignore it, the bedding will be soaked soon.

Therefore, it is necessary to prepare another pair of underwear (which can be placed inside the quilt cover) for timely replacement. The replaced underwear should be washed immediately and exposed to the sun (the inner layer should face outward to the sun) to achieve the effect of antibacterial and sterilization.

There will definitely be a small amount of semen remaining in the urethra after nocturnal emissions. It is best to go to the toilet to urinate so that it can be discharged in time. If possible, it is best to wash it with tap water to make it clean.

sexual morality

Ask students to answer the following questions:

1. Is irregular menstruation normal during adolescence?

Irregular menstrual periods: Many adolescent girls have irregular menstrual cycles and blood volume. In the first few years after menarche, it is normal for menstrual cycles to be up to two or three months apart.

2. Is it okay to beat your waist during menstruation?

When the waist is sore and the legs are swollen, we beat the sore and swollen muscles to relieve the discomfort. Similarly, many women will habitually beat the waist to relieve the soreness and swelling of the waist during menstruation. But doing so was a mistake. Gynecological experts point out that soreness and swelling in the waist during menstruation is caused by pelvic congestion. Beating the waist at this time will cause more congestion in the pelvis, which will in turn aggravate the feeling of soreness and swelling. In addition, beating the waist during menstruation is not conducive to the repair and healing of wounds after endometrial peeling, leading to increased bleeding and prolonged menstruation.

3. Is it okay to eat fried food during menstruation?

Fried foods are also a big no-no for menstruating women. Because of the influence of endocrine progesterone, women during menstruation increase their sebum secretion and make their skin greasy. At the same time, their capillaries dilate and their skin becomes sensitive. Eating fried foods at this time will increase the burden on the skin and easily cause acne, acne, folliculitis, and dark circles. In addition, because the metabolism of fat and water slows down during menstruation, eating fried foods at this time will easily accumulate fat in the body.

4. Is it okay to eat raw or cold food during menstruation?

The excitability of the cerebral cortex of adolescent girls decreases during menstruation, and they often suffer from fatigue, lethargy, emotional instability, irritability or depression. Therefore, it is not advisable to drink strong tea and coffee during menstruation, and eat as little or no cold drinks as possible.

You should drink more boiled water and eat more fruits and vegetables, because fruits are rich in vitamins. Vitamin C is an essential substance for the human body to synthesize collagen and other intercellular substances. It can enhance the body's resistance, reduce fatigue caused by menstrual labor, and reduce infections caused by decreased resistance during menstruation.
