Abstract

Gynecomastia is an unusual side effect associated with testosterone replacement therapy (TRT) that has been traditionally treated with surgery, radiation, or discontinuation of testosterone supplementation. We report here our experience with two cases of gynecomastia in men undergoing TRT who were successfully treated with the aromatase inhibitor anastrozole.
