Is breast development normal for boys?

Breast lumps in men during adolescence are normal physiological changes. Breasts are mainly composed of breast tissue, fat and connective tissue. The surface of breast cells has a unique structure that can identify and absorb estrogen. When estrogen fuses with the protein kinase of breast cells, the metabolism of breast cells becomes active, causing breast cell proliferation and breast development.

After male adolescents enter puberty, the testicles not only produce androgen, but also metabolize a small amount of estrogen, of course, its content is very small. Estrogen causes the mammary gland cells at the nipple to continue to reproduce, causing breast lumps. Breast lumps in adolescent boys are often limited to the nipples, and sometimes they may be painful when touched. According to statistics, among male adolescents aged 13-15, 1/3-2/3 find that one or both sides have breast lumps. The nipples are raised, the diameter of the nipples is increased, and there is pigmentation, but less than 1/5 of the cases of breast lumps occur. Some boys do not pay attention to the small changes in their bodies, and may not be aware of this change in the breasts. Because the increase in the amount of estrogen in male adolescents during puberty is temporary, this type of breast lumps usually disappear spontaneously after a few months to a year. Therefore, whether it is a boy or his parents, there is no need to feel confused and restless.

If some boys who have entered puberty find lumps in their breasts, don't feel anxious, because this is normal and is caused by the influence of estrogen levels.

It is normal for men to have breast lumps during puberty. After men enter puberty, their testicles not only produce androgen, but also produce a small amount of estrogen. Estrogen causes the mammary gland cells at the nipple to continue to multiply, causing lumps in the breast. Breast lumps in adolescent boys are often limited to the underside of the nipple.

Because the increase in estrogen levels during puberty is short-lived, this type of breast lump usually disappears on its own within a few months to a year. When encountering a lump in the breast, boys must not be overly nervous.
