Decreased libido disproportionately affects patients with depression. The relationship between depression and decreased libido may be blurred, but treating one condition frequently improves the other. Medications used to treat depression may decrease libido and sexual function. Frequently, patients do not volunteer problems related to sexuality, and physicians rarely ask about such problems. Asking a depressed patient about libido and sexual function and tailoring treatment to minimize adverse effects on sexual function can significantly increase treatment compliance and improve the quality of the patient's life.
