Is it normal for boys to have breast development?

Breast lumps in male puberty are normal physiological changes. Breasts are mainly composed of mammary gland tissue, human fat and connective tissue. The surface of mammary gland cells has a unique structure that can identify and accept estrogen. When estrogen combines with the protein kinase of mammary gland cells, the metabolism of mammary gland cells becomes active, causing mammary gland cells to proliferate and the breasts to develop protrusions.

When male adolescents enter puberty, the male testicles metabolize testosterone and a small amount of estrogen, of course, the content is very small. Estrogen causes the mammary gland cells at the nipple to continue to multiply, causing breast lumps. Breast lumps in adolescent boys are often limited to the bottom of the nipple, and sometimes they may be painful to touch. According to statistics, among male adolescents aged 13-15, 1/3-2/3 of them find one or both sides of the breast. The nipples are raised, the diameter of the nipples is increased, and there is pigmentation, but less than 1/5 of the cases have breast lumps. Some boys do not pay attention to the minor changes in their bodies and may not notice the changes in their breasts. Because the increase in the amount of female hormones in male adolescents during puberty is temporary, such breast lumps usually disappear on their own after a few months to a year. Therefore, both boys and parents do not need to feel confused or uneasy.
