Secondary developmental characteristics of boys

Puberty refers to the first reproductive stage marked by the development of the reproductive organs and the growth of secondary sexual characteristics. In humans and higher primates, it is marked by the first menstruation in females; specifically refers to the age of puberty.

Puberty refers to the transition period from childhood to adulthood. Puberty is a critical period of rapid physical growth and development, and is also the second peak period of growth and development in life after the neonatal period. The World Health Organization (WHO) stipulates that the puberty period is 13-19 years old. Girls' puberty starts and ends about 2 years earlier than boys. There are large individual differences in the age of entering and ending puberty, which can be about 2 to 5 years apart.

Overall features

Physiological development, embodied in estrus, has a significant impact on the psychological and social development of adolescents during puberty, resulting in many key features of this period:

Puberty is a period of transition

Puberty is the transition period from childhood to adulthood. Puberty is generally distinguished from childhood in many aspects, with the distinction being sexual maturity. For men, sexual maturity is manifested by frequent ejaculation (usually during the night when the body is sleeping well); for women, it is menstruation, the first period. The physiological development trend, with estrus as the key, makes adolescents have social development and psychological characteristics that are significantly different from those of children. In childhood, individuals rely on adults, who control and decide the specific content and level of children's daily life and activities; children are not responsible for their own personal behavior. As they grow older, the scope of their daily lives and the themes of their activities become increasingly complex, giving them characteristics that are different from those of children.

They gradually develop a certain special will and sense of mission and decide how to carry out some activities. They will be subject to certain criminal penalties for their personal behaviors, especially some criminal offenses. But adolescents are also different from adults. Although they have a certain degree of self-awareness, they are not completely independent; in many aspects, especially in terms of material conditions, they still have to rely on their parents; they have not become fully responsible people, and they do not have to be subject to criminal penalties for all their personal behaviors. It is not difficult to see that the influence of this transition period between children and adults has caused adolescents to become what is often called marginalized people in social psychology. The variability of their influence and the variability of the requirements clearly put forward to them by social development have caused them to have many unique mental health problems.

Puberty is a developmental trend

Puberty is the stage of human growth and development. Studies have shown that there are two periods in a person's life when the body grows and develops rapidly and the proportions of various parts of the body undergo significant changes. One is the early parturient period and the first six months after birth, and the other is puberty. The rapid growth and development during puberty is called the puberty hypertrophy state. In fact, this state begins just before estrus or at the same time as estrus, and ends six months to a year after estrus. Men's rapid growth begins at the age of 10.5 to 14.5, reaches its peak at around 14.5 to 15.5 years old, and then gradually slows down. By the age of 18, their height has reached a sufficient level of growth and development, and their weight, muscle strength, shoulder width, pelvic width, etc. have also been improved. In addition, their sexual function and secondary sexual characteristics have also developed fully.

For example, during the menstrual period and the development of secondary sexual characteristics, the reproductive organs of women are gradually improving. Pubic hair begins to appear in the private parts, vaginal secretions begin to increase, the uterus grows and enlarges, and the eggs in the ovarian cortex begin to have different growth and development changes. All these indicate that they have just begun to transition to sexual maturity. The growth and development of the human body and sex have a great impact on the psychological characteristics and social development of adolescents, thus causing a series of mental health problems.
