Background, Evidence, and Definitions

Gynecomastia is benign proliferation of glandular breast tissue in males. Treatment options include discontinuation of contributing medications, medical therapy for select patients (for example, estrogen receptor modulators), and surgical options such as mastectomy with or without liposuction; choice of approach depends on gynecomastia grade, tissue type (glandular vs. fatty), and patient factors. Mastectomy can be performed via open or minimally endoscopic techniques and severe cases may require larger incisions.

Term	Definition
Gynecomastia	Breast enlargement in boys or men due to a benign (non-cancerous) increase in breast tissue (Endocrine Society, 2022).
ASPS Gynecomastia scale Grade II	Moderate breast enlargement exceeding areola boundaries with edges that are indistinct from the chest.
ASPS Gynecomastia scale Grade III	Moderate breast enlargement exceeding areola boundaries with edges that are indistinct from the chest with skin redundancy present.
ASPS Gynecomastia scale Grade IV	Marked breast enlargement with skin redundancy and feminization of the breast.
Functional or Physical Impairment	A deviation from normal function of a tissue or organ resulting in a significantly limited, impaired, or delayed capacity to move, coordinate actions, or perform physical activities; inability to participate in sports or social activities alone is not sufficient.

Hayes Evidence Analysis (2024): identified 8 abstracts (single-arm studies); no clear strong support for mastectomy from guidelines. Systematic reviews / meta-analyses: Prasetyono 2022 (systematic review of surgical approaches, 18 studies, liposuction techniques, variable complication and reoperation rates), Innocenti 2022 (systematic review of complications across aspiration, excision, and combined techniques; combined techniques associated with lower complication rates than excision alone), Trinchieri 2021 (systematic review and meta-analysis of drug-induced gynecomastia showing associations for several drug classes).
