A clinical update on female androgen insufficiency–testosterone testing and treatment in women presenting with low sexual desire
This 2006 review discusses female androgen deficiency syndrome (FADS), characterized by diminished well-being, unexplained fatigue, and decreased sexual desire in estrogen-replete women. Diagnosis is supported by low free testosterone levels, though measurement challenges exist due to assay limitations. Causes include hypopituitarism, adrenal and ovarian insufficiency, glucocorticoid therapy, and age-related decline.
