Gynecomastia is an increase in the amount of breast gland tissue in boys or men, caused by an imbalance of the hormones estrogen and testosterone. Gynecomastia can affect one or both breasts, sometimes unevenly.

Newborns, boys going through puberty and older men may develop gynecomastia as a result of normal changes in hormone levels, though other causes also exist.

Generally, gynecomastia isn't a serious problem, but it can be tough to cope with the condition. Men and boys with gynecomastia sometimes have pain in their breasts and may feel embarrassed.

Gynecomastia may go away on its own. If it persists, medication or surgery may help.

Circumcision is the surgical removal of the skin covering the tip of the penis. The procedure is fairly common for newborn boys in certain parts of the world. Circumcision after the newborn period is possible, but it's a more complex procedure.

Circumcision is a religious or cultural ritual for many Jewish and Islamic families, as well as certain aboriginal tribes in Africa and Australia. Circumcision can also be a matter of family tradition, personal hygiene or preventive health care.

Sometimes there's a medical need for circumcision, such as when the foreskin is too tight to be pulled back (retracted) over the glans. 

Pectoral augmentation is a procedure that can be performed to give the male the definition he’s always desired in the chest region. Long used for reconstruction of the chest after cancer surgery in men, pectoral implants have been safely used to create bulk in the chest region.
