The primary effects of androgens in the body are fundamentally linked to the development of male sexual characteristics. Androgens, such as testosterone, play a crucial role in the process of sexual differentiation during puberty. They are responsible for the development of male reproductive organs and secondary sexual characteristics, including increased muscle mass, body hair growth, and deepening of the voice.

This role in sexual development and maintenance continues throughout adulthood, as androgens contribute to libido, sperm production, and overall male fertility. The influence of androgens extends beyond just physical traits; they also play a part in regulating mood and energy levels, which may have indirect effects on various aspects of health.

While the other options present important functions in the body, they are not primarily associated with androgen action. Regulating blood sugar levels involves hormones like insulin, enhancing immune response is mainly the role of the thymus and various immune cells, and reducing stress levels largely involves hormones such as cortisol and the overall functioning of the adrenal glands.
