Abstract | OBJECTIVE: METHODS: Fifteen male patients with Klinefelter's syndrome, including 12 patients who received previous intramuscular (IM) treatment with testosterone esters, were part of the study population from three phase III clinical studies; 13 completed the studies. Patients applied two TTD systems nightly for 6 months or more. Nocturnal erections were assessed by RigiScan monitoring; sexual function was evaluated by using the Watts and Davidson questionnaires. Hypogonadal symptoms were determined by direct patient questioning. RESULTS: Mean morning serum testosterone levels increased to within normal range in all 13 patients (from 5.9 +/- 3.2 nmol/L at hypogonadal baseline to 22.3 +/- 5.6 nmol/L at 6 months). Luteinizing hormone levels decreased to within normal range in six patients and showed clinically significant decreases in four of the other seven patients (from 25 +/- 12 IU/L at hypogonadal baseline to 17 +/- 11 IU/L at 6 months). Nocturnal erections improved significantly during TTD system therapy in comparison with the hypogonadal state. Patient self-reported measures of sexual functioning were comparable to those during prior IM testosterone treatment and better than during the hypogonadal state. Hypogonadal symptoms decreased during TTD therapy in comparison with hypogonadal baseline. No clinically significant changes were noted in prostate volume, prostate-specific antigen, or lipid values. Three patients experienced anxiety or depression during TTD treatment, requiring discontinuation of therapy in one case and use of antidepressants in the other two. CONCLUSION:
