Testosterone treatment improves body composition and sexual function in men with COPD, in a 6-month randomized controlled trial.
The aim of this study was to assess the effect of a low-dose testosterone on body composition and pulmonary function , as well as on quality of life , sexuality , and psychological symptoms in patients with chronic obstructive pulmonary disease ( COPD ) . Twenty-nine men with moderate to severe COPD were allocated to receive either 250 mg of testosterone or placebo intra-muscularly , every fourth week , during the 26 weeks study period . Fat-free mass increased in the treatment group ( P<0.05 ) , and a significant difference between the treatment and the control group was seen after 26 weeks ( P<0.05 ) . Fat mass decreased in the treatment group ( P<0.05 ) , and there was a significant difference between the treatment and the control group after 12 weeks ( P<0.01 ) . A significantly better erectile function was reported in the treatment group at the final visit ( P<0.05 ) , and the overall sexual quality of life was significantly better in the treatment group after 12 weeks ( P<0.05 ) . No improvement in pulmonary function was found . In conclusion , administration of a low-dose testosterone  to men with COPD for 26 weeks was associated with improvement of body composition , better erectile function and sexual quality of life . Furthermore , there were no clinical or biochemical side effects
