Breast Development in Boys – Causes, Symptoms, Prevention and Treatment

Breast development in boys

Overview and Facts

Puberty is phase of life during which, a person attains sexual maturity accompanied by numerous physical changes. It affects both men and women, but differently. It is a long-term process, which starts with shooting up of the production of hormones that leads to physical changes in the body.

Early in puberty, many boys experience soreness or tenderness around the nipples. Around 75% of them observe some growth of breast. It is the consequence of a biochemical reaction that changes their testosterone into female sex hormone, called estrogen.

Sometimes, there is growth of breast by about 2 inches in diameter under the nipples. Rarely or occasionally, it may be more severe leading to gynecomastia. However, gynecomastia should not be confused with lipomastia, also known as adipomastia.

Lipomastia refers to the accumulation of adipose or fatty tissues in the male chest area with no anomaly in the mammary glands. Whereas, gynecomastia refers to the growth of mammary tissue in the male chest due to hormonal imbalance caused by excess estrogen production. Besides, accumulation of fat tissues can also increase the level of estrogen. Hence, lipomastia and gynecomastia can coexist.


This unusual process of breast development can be distressing in boys, who are trying to create an identity for themselves. Boys may suddenly start hitting the gym or refuse to be seen without a shirt when this condition develops in boys.

It must be noted that all boys and men have breasts, but the amount of breast tissue is small enough to be visible. Boys as babies have some swelling in their nipples when they are born. Girls also have this swelling. In infants, gynecomastia affects over 50% of males due to mother’s estrogen that travels in their bloodstream and the breasts may appear swollen. This usually goes away in a span of 3 months.

During puberty, many hormones are made by the body. Along with androgens (male hormones), some amount of estrogen (female hormone) is also produced. While the hormones are sorting themselves out, the boys start developing some breast tissue during the process. When the breast tissue is so large that it starts to be visible, it is referred to as gynecomastia.

Swelling can be observed under one or both the nipples. This leads to tenderness and soreness. Breasts may not grow much bigger, but swelling may remain for some time while going through puberty. The boys might feel as if everyone is able to notice their breasts, but this may not be true. Around 65% of the boys will have some breast tissue. However, it must be kept in mind that gynecomastia is a normal condition and does not lead to other health issues. Breast tissue does not stay for a longer duration and usually, go away by the age of 20.

A point that must be understood is that if a person is overweight, he may have some fat tissue under the skin around the breasts. This condition is known as lipomastia and is different from the enlarged breast that happens because of hormonal imbalance, known as gynecomastia.

Boys are not very happy with this condition as they feel they are turning into girls or that they may be having breast cancer. In such cases, physical examination must be done to know the exact cause of enlargement of breasts. Whatever may be the cause, surgery is an option to reduce the enlarged breasts and improve the aesthetics.
