Brief summary
The design of the study is a standard double-blind design, which is needed in this study to allow for unbiased evaluation of efficacy and safety. The effect of the additional impact of testosterone replacement therapy in hypogonadal men on muscle strength and quality of life in comparison to physical exercise alone will be assessed. Treatment duration will be 54 weeks, to monitor the increase as well as the steady state of the parameters assessed.
Interventions
Testosterone undecanoate 1000 mg (4 ml) i.m. injection at baseline, at week 6, at week 18, at week 30 and at week 42, respectively
Matching placebo i.m. injections at baseline, at week 6, at week 18 at week 30 and at week 42, respectively
