Among patients with hypogonadism-associated comorbidities, opioid users have the highest incidence of hypogonadism. Data from the Testim Registry in the United States were analyzed to determine the efficacy of testosterone replacement therapy in opioid users vs nonusers. ⋯ Testosterone replacement therapy increased serum testosterone in hypogonadal opioid users and nonusers alike. The data suggest that with testosterone replacement, hypogonadal opioid users might be expected to have similar improvements in sexual function and mood as opioid nonusers.
