How Common Is Gynecomastia and what causes it?

Gynecomastia is a common condition that affects an estimated 70% of men at some point in their lives. According to a study on gynaecomastia and breast cancer in men, published in the National Library of Medicine, the prevalence of “man boobs” was approximately 33% to 41% in a sample of men aged 25-45 years old.

Another study on how common is gynecomastia by the same journal found that the prevalence of excessive breast tissue in men was approximately 57%. The study sampled men aged 50 to 69 years old.

Overall, the prevalence of moobs varies depending on the population studied and the definition used.

Age groups most commonly affected by gynecomastia

How Common Is Gynecomastia

Gynecomastia can occur at any age, but it is common in three age groups: newborns, adolescents, and older men. In newborns, the transfer of estrogen causes gynecomastia from the mother during pregnancy.

This type of excessive breast tissue is usually temporary and resolves within a few weeks or months.

In adolescents, gynecomastia results from hormonal changes during puberty. The hormonal changes can cause breast tissue to enlarge in boys as well as girls.

Adolescent moobs usually resolves without intervention within a few months to two years, but in some cases, it may persist into adulthood.

In older men, man boobs develop because of a decrease in testosterone levels and an increase in estrogen levels. This hormonal imbalance can occur from aging, certain medications, or medical conditions such as liver disease or hypogonadism.

Gynecomastia Symptoms

Gynecomastia is a condition that causes the enlargement of breast tissue in males. The primary symptom is the development of excessive breast tissue in one or both breasts.

This breast tissue may feel firm or rubbery to the touch and may be tender or sensitive to the touch. Other symptoms that may be associated with man boobs include:

Swelling or tenderness in the breast tissue: Gynecomastia can cause the breast tissue to become swollen or tender to the touch.

Pain or discomfort in the breast tissue: It can cause pain or discomfort in the breast tissue, particularly when touched.

Breast asymmetry: In some cases, gynecomastia may cause one breast to be larger than the other, leading to breast asymmetry.

Nipple discharge: Excessive breast tissue can cause the nipple to produce a clear or milky discharge.

Emotional distress: Gynecomastia can cause emotional distress or embarrassment, particularly in adolescents and young adults.

How Common Is Gynecomastia

Gynecomastia is a common condition that affects an estimated 70% of men at some point in their lives. The prevalence varies depending on the population studied and the definition used. It is commonly in three age groups: newborns, adolescents, and older men.

In newborns, excessive chest fat develop because of the transfer of estrogen from the mother during pregnancy. On the other hand, in adolescents, the cause is hormonal changes during puberty.

In older men, excessive breast tissue develops because of a decrease in testosterone levels and an increase in estrogen levels. Underlying causes of moobs can include medications, illegal drugs and alcohol, medical conditions, genetics, and obesity.
