Men get breasts, medically known as
gynecomastia, primarily due to an imbalance between estrogen and testosterone, leading to breast glandular tissue growth, often happening naturally during infancy, puberty, and aging, but can also stem from medications, obesity, certain diseases (liver, kidney), alcohol/drug use (steroids), or tumors. It’s a common, usually harmless, enlargement of glandular tissue, distinct from fat buildup (pseudogynecomastia).
Common Causes & Life Stages:
- Puberty: Temporary hormonal shifts where estrogen temporarily outweighs testosterone, usually resolving on its own.
- Aging: Testosterone levels naturally decrease, and body fat can convert remaining testosterone into estrogen.
- Newborns: Exposure to maternal estrogen can cause temporary enlargement.
Other Factors:
- Medications: Anti-androgens, some HIV drugs, heart meds, and ADHD meds.
- Substance Use: Alcohol, marijuana, amphetamines, heroin, and anabolic steroids.
- Medical Conditions: Liver disease (cirrhosis), kidney failure, thyroid issues, and certain tumors.
- Obesity: Excess fat can increase estrogen levels.
What It Feels Like:
- A firm, rubbery lump under the nipple.
- Can be tender or sore, especially when it starts.
When to See a Doctor:
While often benign, see a healthcare provider to rule out underlying issues, especially if it’s new, painful, or accompanied by other symptoms.
