Changes within the body: How do androgens affect pubertal growth?
Adolescence is an important stage in human development, and the physiological changes during this stage are profoundly influenced by androgens. Androgens, especially testosterone, are essential for the development of male characteristics. With the onset of puberty, androgen levels in the body rise dramatically, and these hormonal changes make an important contribution to the shaping of the body.
Basic effects of androgens
Androgens are hormones that regulate male characteristics and physiological processes. Not only are they synthesized in the male body, they are also present at lower levels in the female body. Although often thought of only as male sex hormones, androgens also influence female sexual desire and arousal.
During puberty, increased androgen levels provide the necessary support for the development of secondary sexual characteristics in males and catalyze sperm production.
The effect of androgens on male development
During fetal development, androgen production begins with the formation of the testicles. During the sixth week, the steroidogenic cells in the testes begin to secrete androgens, which are essential for the sexual differentiation of the organ. As growth and development progress, androgens directly influence the formation of sex tissues, such as the development of the penis and scrotum.
Sexual changes during puberty
When puberty arrives, the sudden increase in androgen causes a series of physiological changes in men. These changes include:
- The sound becomes lower
- Appearance of Adam's apple
- Broaden shoulders
- Increase in muscle mass
- Growth of pubic and related body hair
After puberty, continued high levels of androgens contribute to male fertility. These hormones work together with follicle stimulating hormone (FSH) and luteinizing hormone (LH) in the production of sperm, supporting reproduction and health during the year.
Studies have shown that androgen regulation also affects body fat storage and is closely related to muscle development.
Muscle Mass and Fat Distribution
In addition to affecting the reproductive system, androgens have a significant impact on muscle mass. Men generally have more muscle mass than women, which is mainly attributed to androgens promoting the growth of muscle cells.
In addition, androgens can control the distribution of body fat by inhibiting the function of fat cells, which makes the male body usually see a lower fat percentage after puberty.
Psychological and behavioral changes
Androgens are also associated with psychological, emotional, and behavioral changes. Research suggests that these hormones play a central role in changing human behavior, especially aggression and sexual desire.
Androgens have profound effects on the structure and function of the brain, which leads to changes in psychological states and behavioral patterns.
The relationship between estrogen and androgen
Interestingly, androgens not only exist as male sex hormones, but also play an important role in the hormone balance in women. During the process, androgens can be converted into estrogens, which play a role in women's physiology and sexual desire.
ConclusionOverall, the roles of androgens in adolescence are multifaceted. It not only affects the development of sexual characteristics, but also determines psychological and behavioral changes. As our understanding of androgens increases, future studies may reveal more detailed mechanisms of action of these hormones in different sexes and age groups. Have you ever thought about the long-term impact these internal changes will have on your future health and psychological development?
