The present analysis provides an estimate of the average treatment effects of testosterone therapy in middle-aged men .
OBJECTIVES Ageing in men is associated with a gradual decline in serum testosterone levels and a concomitant loss of muscle mass , accumulation of central adiposity , impaired mobility and increased risk of bone fractures .
Whether and rogen treatment might be beneficial in these subjects is still under debate .
We have carried out a systematic review of r and omized controlled trials ( RCTs ) evaluating the effects of testosterone ( T ) administration  to middle-aged and ageing men on body composition , muscle strength , bone density , markers of bone metabolism and serum lipid profile .
Oral testosterone undecanoate (Andriol®) supplement therapy improves the quality of life for men with testosterone deficiency
In a single-blind , placebo-controlled study , the effects of a 3-month oral administration of 160 mg/day testosterone undecanoate ( And riol ® ) on the quality of life of men with testosterone deficiency were evaluated . The subjects included ten men with primary hypogonadism and 29 with and ropause with sexual dysfunction as the most common problem . The changes in subjective symptoms were evaluated by the PNUH QoL scoring system and the St. Louis University Question naire for and rogen deficiency in aging males ( ADAM ) . Digital rectal examination ( DRE ) was performed and serum testosterone , prostate-specific antigen ( PSA ) and liver profile were monitored . Testosterone undecanoate treatment ( n = 33 ) significantly improved sexual dysfunction and symptom scores of metabolic , cardiopulmonary , musculo-skeletal and gastrointestinal functions compared to baseline and to placebo ( n = 6 ) . ADAM score also significantly improved after 3 months of treatment . Serum testosterone was significantly increased compared to pretreatment levels only in the testosterone undecanoate group . In the placebo group , no significant changes compared to baseline were found for testosterone levels and QoL question naires . No abnormal findings were detected on DRE or laboratory findings in either group . Adverse events , such as gastrointestinal problems and fatigue , were mild and self-limiting . It is concluded that and rogen supplement therapy with oral testosterone undecanoate ( And riol ) restores the quality of life through improvement of general body functions in men with testosterone deficiency
