Androgen deficiency refers to a condition where the body does not produce enough androgens, which are hormones like testosterone that play a crucial role in male health. This deficiency can lead to various symptoms, including reduced libido, fatigue, and loss of muscle mass. It can occur due to aging, medical conditions, or hormonal imbalances. Diagnosis typically involves blood tests to measure hormone levels. Treatment options may include hormone replacement therapy or lifestyle changes to improve overall health. Addressing androgen deficiency is important for maintaining physical and mental well-being, particularly in aging men and those with specific health issues.
