Why do the Breasts of Adolescent Boys Grow? Four Principles for Adolescent Boy Health Care

Enlarged breasts during adolescence are a common occurrence among many boys, and many boys may feel insecure as a result. Today, experts will take you to understand why adolescent boys have enlarged breasts. You don't need to worry so much.

Causes of enlarged breasts during adolescence

During a man's lifetime, there are two periods when physiological breast enlargement occurs due to hormonal and endocrine factors.

One is that when a baby is first born, due to the influence of residual estrogen in the mother's body, it can cause breast enlargement, which usually lasts for 1 week to a few months before it subsides on its own.

The second is during adolescence. At this point, the endocrine function of boys gradually becomes active, and while the testicles secrete a large amount of androgens, estrogen also increases. At first, the amount of androgens far exceeded that of estrogen, so that the effect of estrogen on human organs was not significant. After a period of time, some boys may experience a temporary hormonal imbalance due to temporary hormonal disorders and relatively high levels of estrogen secretion. This can cause a temporary hormonal imbalance, leading to an increase in estrogen levels in the body. In addition, the sensitivity of breast tissue to estrogen increases, leading to an enlarged breast chamber. At the same time, it is also related to the increase in growth hormone and adrenal cortical hormone during this period, which enhances breast stimulation.

Adolescent men's breasts increase, mostly manifested under one or both nipples or areolas, with a hard lump of varying sizes, usually disc-shaped. The smaller one is like a cherry, while the larger one is half the size of a walnut, with a diameter of 2 to 3 centimeters. The edges are clearly defined, and there is swelling and tenderness, and even milk like secretion. Some people suspect that it is a tumor or other lesion, while others suspect that sexual changes have occurred, causing anxiety and anxiety. In fact, this is a physiological phenomenon in boys' adolescence, which mostly occurs between the ages of 13 and 16, with an incidence rate of about 40% to 50%, usually lasting for about a year, with a few people lasting slightly longer. This physiological breast enlargement does not harm health and generally does not require any treatment. As endocrine function gradually improves, it will naturally subside.

If the breast enlargement of adolescent boys is more pronounced, even more pronounced than that of girls, and does not subside for a long time, then it is necessary to go to the hospital for examination to see if there is an endocrine problem. If the breasts appear particularly large due to body obesity, only moderate weight loss is needed to subside.
