Gynecomastia, commonly known as male breast enlargement, is medically defined as the growth of tissue in the breasts as a result of an imbalance in the hormones responsible for milk production, testosterone and estrogen. This hormonal imbalance usually occurs when the level of testosterone in the body decreases and the hormone estrogen increases. These hormonal changes are more common during puberty and in men over the age of 50. While it may occur temporarily during puberty due to hormonal fluctuations, it is more likely to become permanent in old age. This condition becomes evident in the form of mass, sagging, cracking and swelling in the male breast area. Gynecomastia can be psychologically disturbing as well as affecting the physical appearance of the individual. It can have negative effects on body image and self-confidence, especially among young men. Therefore, it is important for individuals who encounter this condition to seek appropriate medical assistance and begin the necessary treatment process.
