Summary of results from the 2 × 2 factorial trial of Testosterone and Exercise (TEX) which directly compared the combined and independent impacts of T treatment (in the physiological range) and supervised center-based exercise. Upper: Changes from baseline following the 12 week intervention, **P < 0.001, *P < 0.05 for week 12 change from baseline compared with placebo + no exercise group change. Lower: Infographic summarising the results from our TEX trial. T + Ex column indicates whether the addition of testosterone (T) to exercise training (Ex) provides additive benefit compared to exercise alone. ‘ + ’ indicates improvement, ‘–’ indicates no significant change
