Dr. Matsumoto’s research program examines the physiological effects and mechanisms of action of androgens and their active metabolites in young and aging men and animals.  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, brain neuropeptide regulation of body weight and food intake, prostate gland function, pituitary gonadotropin secretion, spermatogenesis, sexual function, cognitive function, mood and quality of life.  Dr. Matsumoto is an investigator in the NIH Center for Research in Reproduction and Contraception (CRRC) at the University of Washington and the NCI Pacific Northwest Prostate Cancer Specialized Program of Research Excellence (SPORE) at the Fred Hutchinson Cancer Research Center, and an affiliate investigator in the Clinical Nutrition Research Unit (CNRU) at the University of Washington.

Dr. Matsumoto directs and sees patients in the GRECC Osteoporosis & Andrology Clinic, a multi-disciplinary subspecialty referral clinic for the evaluation and treatment of patients with osteoporosis and other metabolic bone disease, recurrent nephrolithiasis, male hypogoandism and sexual dysfunction.    He attends, sees patients and teaches fellows, internal medicine residents and medical students in the Endocrine Clinic, a subspecialty referral clinic that evaluates and treats patients with general endocrine and metabolic disorders, including diabetes mellitus, lipid disorders and thyroid disease.  He serves as an attending physician, sees patients and teaches residents and medical students on the inpatient General Medicine Service and on the Housestaff Service of Transitional Care Unit.  Dr. Matsumoto directs the VA Special Fellowship Program in Advanced Geriatrics, a fellowship for research training in gerontology, geriatric medicine and geriatric psychiatry.  He is a faculty mentor on the University of Washington NIH Reproductive Biology Training T32 Grant and NIH Male Reproductive Health Research (MRHR) Career Development K12 Grant.  He mentors junior faculty and fellows in geriatric medicine and metabolism, endocrinology and nutrition.
