Testosterone is a key hormone primarily associated with male health but also plays important roles in females. Produced mainly in the testes for men and in smaller amounts by the ovaries and adrenal glands in women, it regulates various bodily functions. In men, testosterone is crucial for the development of male reproductive tissues, muscle mass, bone density, and the production of red blood cells and sperm. In women, it supports bone strength, libido, and muscle growth. Maintaining balanced levels is essential, as imbalances can lead to health issues such as fatigue, mood changes, or physical symptoms.
