What causes breast enlargement in men?
Gynecomastia is most commonly caused by an imbalance between estrogen and testosterone hormones. Estrogen follows female characteristics, including breast enlargement. Testosterone controls male properties, such as muscle mass and body hair. Although each of these hormones produces the usual properties seen in men and women; males produce small amounts of estrogen, and females produce small amounts of testosterone. Male estrogen levels that are too high or unbalanced with testosterone levels cause gynecomastia.
