Question

Quizplus · Accepted Answer

Hormonal imbalances, specifically an increase in estrogen levels relative to testosterone, are the most common cause of gynecomastia. This can occur during puberty, with age, or due to certain medication or health conditions that affect hormone levels. Birth defects and prenatal drug exposure may also contribute to gynecomastia, but they are less common causes. Aging alone is not a direct cause of gynecomastia, but hormonal changes that occur with age can contribute to its development.
