A vital component of hormone replacement therapy is not only increasing testosterone levels but also lowering estrogen levels. The increased levels of estrogen and not enough testosterone in a male’s body will cause the breasts to enlarge. If the imbalance of hormones continues for a certain period of time, gynecomastia can develop.
Gynecomastia and low testosterone levels are easily treatable. Gynecomastia is known as a condition when the glandular tissue in mens breasts grow in one or both breasts. The swelling in the breasts can begin in the early stages of puberty and more commonly with men over the age of forty-five. Gynecomastia affects about 1 in 4 men between the ages of fifty and eighty. The condition usually is not harmful or serious but sometimes can cause enlarged breasts and sore breast tissue.
