Effects of testosterone replacement in men with opioid-induced androgen deficiency: a randomized controlled trial
Abstract Symptomatic and rogen deficiency is common in patients taking opioid analgesics , as these drugs potently suppress the hypothalamic – pituitary – gonadal axis . However , the efficacy of testosterone replacement in this setting remains unclear . The objective of this trial was to evaluate the efficacy of testosterone replacement on pain perception and other and rogen-dependent outcomes in men with opioid-induced and rogen deficiency . We conducted a r and omized , double-blind , parallel placebo-controlled trial at an outpatient academic research center . Participants were men aged 18 to 64 years on opioid analgesics for chronic noncancer pain , and total testosterone levels were < 350 ng/dL. Participants were r and omly assigned to 14 weeks of daily transdermal gel that contained 5 g of testosterone or placebo . Primary outcomes were changes in self-reported clinical pain and objective ly assessed pain sensitivity . Sexual function , quality of life , and body composition were also assessed . The mean age was 49 years . The median total and free testosterone levels at baseline were 243 ng/dL and 47 pg/mL and 251 ng/dL and 43 pg/mL in the testosterone and placebo arm , respectively . Of the 84 r and omized participants , 65 had follow-up data on efficacy outcomes . Compared with men assigned to the placebo arm , those assigned to testosterone replacement experienced greater improvements in pressure and mechanical hyperalgesia , sexual desire , and role limitation due to emotional problems . Testosterone administration was also associated with an improvement in body composition . There were no between-group differences in changes in self-reported pain . In conclusion , in men with opioid-induced and rogen deficiency , testosterone administration improved pain sensitivity , sexual desire , body composition , and aspects of quality of life
