How do androgens affect muscle mass in males?

Androgens, which are male hormones such as testosterone, play a significant role in the development and maintenance of muscle mass in males. The correct choice highlights that androgens promote an increase in muscle growth through several physiological mechanisms.

One of the key effects of androgens is their role in stimulating protein synthesis within muscle cells, which leads to increased muscle fiber size and strength. This anabolic effect not only enhances the growth of new muscle tissue but also helps in the recovery and repair of existing muscle fibers after exertion. Additionally, androgens can influence the metabolism of fat and carbohydrates, contributing to an overall improved body composition that favors muscle development.

Furthermore, the presence of androgens enhances the activity of satellite cells, which are crucial for muscle repair and regeneration, thus further supporting muscle hypertrophy. As a result, men with higher levels of androgens tend to have greater muscle mass and strength compared to those with lower levels.

The correct assertion underscores the vital role androgens play in promoting muscle growth, making it clear why this is the appropriate response to the question regarding their impact on muscle mass in males.
