Abstract

Gynecomastia, a benign expansion of the glandular tissue in the male breast, is frequent in middle-aged and older males as well as in infancy and adolescence. Male obese patients frequently exhibit pseudogynecomastia, which is defined as fat-deposition without glandular proliferation. Its causes can be anything from uncommon neoplasms to harmless physiological processes. This systemic review aimed to examine surgical management strategies for gynecomastia. Data sources were PubMed/Medline and Embase. This review investigated English-language articles (from 2010 to 2023) according to the PRISMA guidelines. Surveys and analyses of national databases were the most widely used methods. The research identified 395 studies, out of which five were eligible for inclusion in the current analysis. Since estrogen and androgens are in balance in males, gynecomastia can be caused by any illness or medicine that raises or lowers the amount of circulating estrogen or androgen, respectively, resulting in an increase in the ratio of estrogen to androgen. Because there are so many potential causes, including neoplasms, a comprehensive history and physical examination are essential. Following the diagnosis of gynecomastia, treating the underlying cause is necessary. If underlying reason is not found then careful observation is necessary. Medical treatment might be an option if gynecomastia is severe and have started recently; if this proves unsuccessful, glandular tissue might be required to be removed surgically.
