Which hormones are primarily responsible for regulating metabolism and development in males?

The primary hormones responsible for regulating metabolism and development in males are androgens. These hormones, which include testosterone, play a crucial role in the development of male primary and secondary sexual characteristics, such as increased muscle mass, body hair growth, and deepening of the voice. Additionally, androgens influence metabolic processes by promoting protein synthesis and impacting energy metabolism, thereby affecting how the body uses and stores energy.

Insulin primarily regulates glucose metabolism and is critical for maintaining blood sugar levels. While this hormone plays a significant role in overall metabolism, it does not specifically govern male development.

Thyroxine, a hormone produced by the thyroid gland, is essential for growth and metabolism but is not gender-specific; it affects metabolic rate and development across both sexes.

Glucagon, produced by the pancreas, works to raise blood glucose levels when they are low, thus playing a role in glucose metabolism rather than the broader regulatory functions associated with male development and overall metabolic regulation.

Therefore, androgens are the key hormones in this context, directly influencing both metabolic pathways and developmental processes specific to males.
