puberty

concept:

It is the period when human gonads begin to develop and mature.

It is the transition stage from childhood to adulthood.

The World Health Organization considers the age range of puberty to be 10 to 20 years old.

Puberty is a necessary stage for a child to become an "adult". Puberty begins between the ages of 10-14 for women and between 12-17 for men. Puberty represents the stage from which an individual's sexual function has not yet taken effect to its mature function. In this stage, the individual's sexual development is mature and has the ability to have children.

Characteristics of growth and development during adolescence

(1) Changes in body shape

1. Rapid growth in height

2. Rapid weight gain

(2) The functions of the brain and internal organs tend to be perfected

1. The structural and functional development of the brain is gradually improved.

2. Enhance heart function

Stroke volume increases, heart rate decreases

3. Enhance respiratory function

Increased lung capacity

(3) Sexual development and maturation

The testicles secrete androgens, the main component of which is testosterone. When puberty begins, testosterone not only promotes spermatogenesis but also has many effects throughout the body. It promotes the growth of all accessory reproductive organs - ducts, glands and penis, in order to facilitate their adult functions. Male secondary sexual characteristics also rely on the stimulation of testosterone. Male secondary sexual characteristics include hair growth on the mons pubis, armpits and face, enlargement of the throat, Adam's apple, deep voice, thickening and oily skin, bone growth and bone density, and enhanced skeletal muscle development. Testosterone also enhances metabolic rate and affects human behavior.

Basic concepts of adolescence

Sexual characteristics:

Differences inside and outside the body due to gender differences, divided into primary sex characteristics and secondary sex characteristics

Primary sexual characteristics:

Differences in reproductive organs between men and women

Male: testicles, epididymis, vas deferens

Female: ovaries, fallopian tubes, uterus

erection

Penile erection occurs in newborn babies, also in childhood, and most frequently after entering puberty. Usually when boys go to bed or wake up in the morning, they will have a natural penis erection. If adolescent boys have no penile erection, it may be due to an abnormality of male hormones and nervous system, and they need to seek medical diagnosis.

nocturnal emissions

A man has the phenomenon of ejaculation while sleeping, which is called a wet dream. Nocturnal emissions, also known as nocturnal emissions, are a natural physiological reaction.

When a boy reaches puberty, the sperm continues to produce sperm, which is stored in the seminal vesicles, vas deferens and accessory sperm.

If these organs are filled with sperm, during sleep, due to the relaxation of nerves and muscles, reflex ejaculation will occur and excess sperm will be excreted. This phenomenon is called a wet dream.

There is no harm in having a wet dream. Drinking a lot of water before going to bed, wearing tight underwear or sleeping on your stomach are more likely to cause a wet dream, so they should be avoided.

When a boy has a wet dream, he should immediately change the stained clothes. It is polite to wash these clothes yourself. If not washed immediately, the clothes must be soaked in water to avoid leaving unsightly yellow stains after leaving them for too long.

Secondary sexual characteristics:

It refers to the external differences in gender that appear between men and women after entering puberty, except for the reproductive organs.

Tertiary sexual characteristics

It refers to gender differences in psychology, behavior, emotions, habits, etc. As secondary sexual characteristics develop, tertiary sexual characteristics occur, but changes in tertiary sexual characteristics are greatly influenced by culture. There is no clear physiological basis for this.

General characteristics of pubertal development stages

Physical growth accelerates and a second growth spurt occurs.

Each internal organ increases in size and matures in function.

The endocrine system is active and the secretion of hormones related to growth and development increases significantly.

The development of the reproductive system suddenly accelerates, and reproductive functions are already available in late adolescence.

Secondary sexual characteristics develop rapidly, making the morphological differences between men and women more obvious.

Along with the development of form and function, there are also drastic psychological and behavioral changes, which are prone to mental health problems.
