Second developmental characteristics of boys

Puberty refers to the stage when the male reproductive organs have matured and matured, and secondary sexual characteristics have grown and developed. In humans and higher primates, it is marked by the first menstrual period in females.； Specifically refers to the age of puberty.

Puberty refers to the transition period from children to adults. The puberty period is a critical period for rapid physical growth and development. It is also the second peak period of growth and development in life after the newborn period. The World Health Organization (WHO) requires that the puberty period is 13-19 years old. Girls' puberty begins and ends about 2 years earlier than boys. There are great individual differences in the entry and end ages of puberty, which can be about 2 to 5 years apart.

Overall features

The physiological development with estrus as the specific content has a significant impact on the psychological and social development of adolescents during puberty, resulting in several important characteristics of this period:

Puberty is a transitional period

Puberty is the stage when an individual transitions from a child to an adult. Generally, people distinguish puberty from childhood in many aspects, and the boundary between them is sexual maturity. For men, the symptom of sexual maturity is frequent nocturnal emissions (usually frequent nocturnal emissions during sleep at night) ； The lady is on her period, that is, her first period. The physiological development trend, with estrus as the core, gives teenagers social and psychological characteristics that are significantly different from those of children. Individuals rely on adults during childhood, and adults control and make decisions about the specific content and aspects of children's daily lives and activities. ； Children are not responsible for their own personal behavior. As age increases, the scope of daily life and the themes of activities gradually become more complex, giving teenagers different characteristics from teenagers.

They gradually develop a certain will and sense of mission and decide how to carry out some activities. You must bear certain criminal penalties for your personal behavior, especially some criminal crimes. But teenagers are also different from adults. Although they have a certain degree of consciousness, they are not completely alone yet. ； In many aspects, especially in terms of material conditions, we also need to rely on our parents. ； They have not yet become fully responsible persons, and they are not necessarily responsible for all their actions. It is easy to see that the influence of this transition period between children and adults makes teenagers become what is often called marginalized people in social psychology. The variability of their influence and the variability of the requirements that society imposes on them cause them to cause many unique mental health problems.

Puberty is a developmental trend stage

Puberty is the stage during which human body grows and develops. Research shows that in a person's life, there are two stages when the human body grows rapidly and the proportions of each part of the human body change significantly. One is during the early stages of delivery and the first half a year after birth, and the other is during puberty and development. The rapid growth and development during puberty is called the rapid development of puberty. In fact, this situation begins before or at the same time as estrus, and ends about half a year to a year after estrus. Men's rapid growth starts from the age of 10.5 to 14.5 years old, reaches its peak at about 14.5 to 15.5 years old, and then slowly slows down. By the age of about 18, the height has reached a sufficient level of growth. Weight, muscle strength, shoulder width, pelvic width, etc. have also been improved. In addition, sexual function and secondary sexual characteristics have also matured.

For example, while women undergo external changes such as menstruation and secondary sexual characteristics, their male reproductive organs also gradually mature. Pubic hair begins to appear in the private parts, vaginal secretions begin to increase, the uterus enlarges, and the eggs in the uterine and ovarian cortex begin to undergo different stages of growth and development. All this shows that the transition to sexual maturity has begun. Because the growth and development of the human body and sex has had a significant impact on the psychological characteristics and social development of teenagers, it has also caused a series of mental health problems.
