CONTEXT: Anorexia nervosa (AN) is a psychiatric illness with considerable morbidity and no approved medical therapies. We have shown that relative androgen deficiency in AN is associated with greater depression and anxiety symptom severity. OBJECTIVE: To determine whether low-dose testosterone therapy is an effective endocrine-targeted therapy for AN. DESIGN: Double-blind, randomized, placebo-controlled trial. SETTING: Clinical research center. PARTICIPANTS: Ninety women, 18 to 45 years, with AN and free testosterone levels below the median for healthy women. INTERVENTION: Transdermal testosterone, 300 μg daily, or placebo patch for 24 weeks. MAIN OUTCOME MEASURES: Primary end point: body mass index (BMI). Secondary end points: depression symptom severity [Hamilton Depression Rating Scale (HAM-D)], anxiety symptom severity [Hamilton Anxiety Rating Scale (HAM-A)], and eating disorder psychopathology and behaviors. RESULTS:Mean BMI increased by 0.0 ± 1.0 kg/m2 in the testosterone group and 0.5 ± 1.1 kg/m2 in the placebo group (P = 0.03) over 24 weeks. At 4 weeks, there was a trend toward a greater decrease in HAM-D score (P = 0.09) in the testosterone vs placebo group. At 24 weeks, mean HAM-D and HAM-A scores decreased similarly in both groups [HAM-D: -2.9 ± 4.9 (testosterone) vs -3.0 ± 5.0 (placebo), P = 0.72; HAM-A: -4.5 ± 5.3 (testosterone) vs -4.3 ± 4.4 (placebo), P = 0.25]. There were no significant differences in eating disorder scores between groups. Testosterone therapy was safe and well tolerated with no increase in androgenic side effects compared with placebo. CONCLUSION:Low-dose testosterone therapy for 24 weeks was associated with less weight gain-and did not lead to sustained improvements in depression, anxiety, or disordered eating symptoms-compared with placebo in women with AN.
