What is Gynecomastia?

Gynecomastia is derived from the Greek term “gyno” for feminine, and the Greek term “mastos” for breast. The condition involves excessive development of the breast in the male. Gynecomastia may be the result of an increase in ductal tissue and stromal tissue of the male breasts commonly referred to as glandular tissue. In conjunction with the increased ductal and stromal tissue, there may be an increase in the size of adipocytes which is typically referred to as the fatty component. Gynecomastia may be the result of a variety of hormonal, genetic, neoplastic or environmental changes. However, a majority of the cases occur without a clearly defined causal agent and are referred to as idiopathic gynecomastia.
