Testosterone, the king of male hormones, plays a crucial role in physical and mental well-being in men. It fuels muscles, sex drive, energy levels, and even mood. Testosterone also plays a part in women's health, contributing to bone strength, lean muscle mass, overall well-being, and energy levels. It also significantly impacts sexual desire and satisfaction. While testosterone is often associated with men, women produce it as well, albeit in much smaller amounts —10 to 20 times less than males.
