Overview
Gynecomastia is diagnosed clinically after a thorough history and physical examination. A recent onset of gynecomastia with tenderness on the examination require the following laboratory studies: Serum concentrations of human chorionic gonadotropin (hCG), LH, testosterone, and estradiol. The hormonal levels may vary depending on the underlying cause.
Laboratory Findings
- Asymptomatic gynecomastia which is discovered on physical examination has a very low diagnostic yield and usually normal blood hormone levels.
- Gynecomastia which is tender and of recent onset should have, following lab work up:[1][2][3][4]
