Testosterone is the principal male sex hormone and plays a crucial role in reproductive health. Produced mainly in the testes, testosterone regulates sexual development, sperm production, muscle mass, and bone density.
During puberty, testosterone triggers the development of secondary sexual characteristics such as facial hair, voice deepening, and increased muscle growth. In adulthood, the hormone continues to support libido, mood stability, and energy levels.
However, testosterone levels can decline due to aging, medical conditions, or lifestyle factors. One medical disorder related to low testosterone levels is Testosterone Deficiency Syndrome.
Symptoms may include fatigue, decreased libido, loss of muscle mass, and reduced bone density. Diagnosis typically involves blood tests that measure hormone levels.
Appropriate treatment may involve lifestyle changes, medication, erotic or hormone replacement therapy under medical supervision.
