General aim To investigate the effect and clinical relevance of testosterone therapy combined with exercise and diet counselling in hypogonadal men undergoing bariatric surgery. Objectives To evaluate the effect of testosterone therapy combined with exercise and diet counselling on muscle strength, body composition, hormones, components of the metabolic syndrome, inflammation, sexual function, and quality of life after weight loss in obese, hypogonadal men undergoing bariatric surgery.
