With gynecomastia, tissue inside the breast glands grows. This can cause female-appearing breasts. Gynecomastia guy-nuh-koh-MAS-tee-uh is swelling of the breast 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.
There is very little actual breast tissue present at birth, although a few days after birth it is not at all unusual for babies to produce what is referred to as 'witches milk' from their nipples. This is said to be caused by the strong influence of the mother's hormones just before delivery, and then the milk is not present again until other conditions later in life cause lactation to start up. Females reach a certain time during which their breasts begin to develop further.
Because of this, many of the breast enlargement techniques that work for women work just as well for men. This option is a popular way of instantly getting bigger breasts for both men and for women, but unlike the other male breast enlargement techniques — this one does not work as well for men as it does for women. Because most men go into the operation with very little breast tissue, it makes it difficult for the plastic surgeon to find a comfortable nook in which to place the silicone inserts. This makes the treatment much more difficult for men than for women.
