What Causes Gynecomastia?
What is Gynecomastia?
It is defined as swelling of the breast tissue in boys or men. It can affect one or both breasts, sometimes unevenly.
It is caused by an imbalance of the hormones estrogen and testosterone. The decrease in the amount of the hormone testosterone compared with estrogen results in Gynecomastia.
Gynecomastia in Infants: Due to the effect of mother’s estrogen, more than half of male infants are born with enlarged breasts which generally go away within two to three weeks after birth.
Gynecomastia during puberty: It is relatively common as it is caused by hormone changes. It goes away without treatment within six months to two years.
Gynecomastia in men: The prevalence of gynecomastia peaks between the ages of 50 and 69.

The doctor will perform a physical examination that may include careful evaluation of breast tissue, abdomen, and genitals. Tests are also done such as:
- Blood tests
- CT scans
- Testicular ultrasounds
- Tissue biopsies
Most cases of gynecomastia regress over time without treatment. If it is caused by an underlying condition then it may need treatment.
Surgery such as liposuction and mastectomy is done to remove excess breast tissue.
