Klinefelter syndrome (47, XXY) is the most common sex chromosome aneuploidy in males. Principal effects include metabolic and endocrine disorders related to testosterone deficiency. Although not all males develop the characteristic symptoms of Klinefelter syndrome, testosterone deficiency is present in all of them. An increased incidence of anxiety and depression is reported in boys and adolescents with 47, XXY. Depressive symptoms have been associated to testosterone deficiency and also as an adaptive reaction to disease. Psychiatric treatment of depression in patients with Klinefelter syndrome has been limited to drug therapy and supportive psychotherapy. However, studies suggest that testosterone replacement may have an antidepressant effect in depressed adults with testosterone deficiency. The purpose of this case study is to report the course of depressive symptoms in an adolescent subject with Klinefelter syndrome treated with testosterone and psychotherapy.
