Dr. Matsumoto’s research program examines the physiological and clinical effects and mechanisms of action of androgens and their active metabolites in young and aging men. Specifically, his multi-disciplinary and collaborative research program investigates androgen effects on body composition (fat mass, lean mass and bone mineral density), muscle mass and strength, metabolic function, prostate gland and cardiovascular disease, pituitary gonadotropin secretion, spermatogenesis, sexual function, cognitive function, mood and quality of life.
