Gynecomastia in boys?


Doctor, my 8-year-old son is 138 cm tall and weighs 46 kg, which is slightly overweight.
Is it normal for him to have breast tissue? Additionally, his nipples are inverted.
Will this improve as he grows older? Thank you.

Dr. Wu Jingtang reply Breast and Thyroid


Hello: An 8-year-old boy with a height of 138 cm and a weight of 46 kg has a body composition that may be considered within the normal range, although he has some breast tissue.
It is advisable for him to engage in more physical activity.
The inverted nipples can be monitored over time, as they may be related to his weight.
Best wishes, Dr.
Hsin-Yi Wu.

Breast development issues in young boys can be a source of concern for many parents. It is important to understand that during childhood and adolescence, boys can experience various changes in their bodies, including breast tissue development. This phenomenon is often referred to as gynecomastia, which is the enlargement of breast tissue in males.
In your case, your 8-year-old son, who is slightly overweight with a height of 138 cm and a weight of 46 kg, may have some breast tissue that appears more pronounced. This can be considered normal, especially at his age, as hormonal changes can lead to temporary breast tissue development. During puberty, boys experience fluctuations in hormone levels, particularly testosterone and estrogen, which can result in breast tissue growth.
It is also worth noting that the presence of "soft" breast tissue in boys is not uncommon. Many boys may have a bit of fat in the breast area, which can give the appearance of fullness. This is especially true if they are overweight, as excess body fat can contribute to the appearance of breast tissue.
Regarding the concern about inverted nipples, it is important to understand that this can occur in both boys and girls. In many cases, inverted nipples can be a normal anatomical variation and may not require any treatment. As your son grows and undergoes further hormonal changes, it is possible that the appearance of his nipples may change and improve.
In terms of dietary habits, it is essential to encourage a balanced diet that includes fruits, vegetables, and lean proteins. A diet high in processed foods and excessive fats can contribute to weight gain and may exacerbate the appearance of breast tissue. Encouraging physical activity and healthy eating habits can help manage weight and promote overall health, which may also positively influence breast tissue development.

If you have concerns about your son's breast development or if there are any signs of pain, tenderness, or significant changes in breast tissue, it is advisable to consult a pediatrician or a pediatric endocrinologist. They can conduct a thorough examination and, if necessary, perform tests to rule out any underlying hormonal imbalances or other medical conditions.

In summary, it is not uncommon for young boys to have some breast tissue development, especially during childhood and early adolescence. This can be influenced by hormonal changes and body composition. Encouraging a healthy lifestyle and monitoring any changes can help alleviate concerns. If there are persistent issues or worries, seeking medical advice is always a prudent step.
