Outcome and Prognosis

Regardless of the etiology of gynecomastia, the prognosis is excellent when surgery is performed by a surgeon experienced with the disorder. In pathological-induced gynecomastia, medical and surgical treatment of the cause is required. In drug-induced gynecomastia, withdrawal of the medication leads to some regression in 60% of patients; however, this is typically inadequate and requires surgical intervention. If the gynecomastia is of long duration, it is unlikely to spontaneously regress.
