When gynecomastia persists despite addressing its underlying cause, discontinuing implicated medications or substances, and completing a period of watchful waiting — and spontaneous regression does not occur — a further clinical approach becomes appropriate.
The initial approach targets spontaneous regression and resolution of the breast enlargement. This includes treating identifiable underlying pathology, changing or stopping pharmaceutical substances suspected to be causative, encouraging cessation of anabolic androgenic steroid (AAS) use, and watchful waiting. When breast enlargement persists beyond this phase without regressing, the next protocol step applies.

We suggest surgical treatment only for patients with long-lasting GM, which does not regress spontaneously or following medical therapy.
The extent and type of surgery depend on the size of breast enlargement, and the amount of adipose tissue.
