What does gynecomastia refer to?

Gynecomastia refers specifically to the abnormal enlargement of the male mammary glands. This condition can result from various hormonal imbalances, particularly an increase in estrogen levels relative to testosterone. It can occur due to genetic factors, health conditions, or as a side effect of certain medications, leading to breast tissue development in males. This condition is distinct from other options, as it specifically relates to breast tissue rather than any hormonal or cardiac issues. Understanding gynecomastia is important in the context of male health, as it can affect self-esteem and body image, in addition to indicating underlying hormonal or health problems.
