Hormone activity: In puberty there is a surge in hormone activity & males have a small amount of estrogen in their system. Breast tissue in some males is more sensitive to even small amounts & up to half will have transient breast tissue enlargement on one or both sides during puberty. It usually fades within 6-12 mo. Persistence or development of breast tissue at other times suggests an abnormality
