Routine assessment by an endocrinologist and laboratory tests to measure hormone levels aren’t necessary in most adolescent boys with gynecomastia (male breast enlargement), concludes a study in the July issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS).
The cause of adolescent gynecomastia can usually be identified without endocrine testing, according to the study by Jugpal S. Arneja, MD, MBA, and colleagues of University of British Columbia, Vancouver, Canada.
