Female Androgen Insufficiency

Meaning

Female Androgen Insufficiency (FAI) is a distinct clinical syndrome characterized by consistently low levels of circulating androgens, such as testosterone and DHEA, often accompanied by a specific, bothersome cluster of symptoms. These symptoms typically include persistent unexplained fatigue, significantly diminished libido, reduced overall sense of well-being, and potentially a measurable decrease in bone density and muscle mass. FAI is considered a diagnosis of exclusion, requiring the clinician to carefully rule out all other potential causes for these nonspecific complaints.
