Overview
Gynecomastia is diagnosed clinically after a thorough history and physical examination. Gynecomastia with recent onset and tender on the examination should have serum concentrations of human chorionic gonadotropin (hCG), LH, testosterone, and estradiol measured. The hormonal levels may vary depending on the underlying cause.
Laboratory Findings
- Asymptomatic gynecomastia which is discovered on physical examination and has no known cause found on physical examination has a very low diagnostic yield of blood hormone levels..
- Gynecomastia which is tender and of recent onset should have, following lab work up:[1][2][3][4]
