The main difference between gynecomastia and pseudogynecomastia is the type of tissue. Gynecomastia is characterised by enlarged glandular tissue that feels like a firm mould under the areola and nipple area, whereas pseudogynecomastia is composed solely of subcutaneous fat. The pinch test is a universal assessment that can help distinguish them. Here's how to assess your condition and understand your treatment options.
Comparison Table between Gynecomastia and Pseudogynecomastia
Typically, a man's chest features small, flat nipples that reveal the underlying pectoral muscles, especially when flexed.
It's natural for men to worry when their breasts seem to enlarge or swell. They'll turn to the Internet to search for their symptoms and land on articles regarding gynecomastia, a condition caused by the enlargement of male breast tissue.
However, this isn't the only cause of enlarged male breasts. In some cases, it's caused by excess chest fat.
Let's look at gynecomastia and pseudogynecomastia.
The Self-Pinch Test (Step-by-Step Guide)
The pinch test is a self-assessment to distinguish gynecomastia from pseudogynecomastia. By pinching the tissue under the nipple, gynecomastia is indicated if a firm, rubbery, or fibrous disc is felt, often accompanied by tenderness, whereas fat feels soft and pliable.
How to Perform the Pinch Test
- Stand in front of the mirror with your shirt off.
- Relax your arms on the side and visually observe your chest shape and areola, as well as the position of your nipples.
- Gently pinch the area around your nipple and areola with your thumb and index finger. You are checking for a hard mount that feels rubbery beneath the areola and nipple. Enlarged glandular tissue feels sensitive, but normal chest fat feels like fat in other parts of the body.
- Repeat the checks on the other side of your chest, as gynecomastia can occur on one side (unilateral) or both sides (bilateral)
Result Interpretation
- Firm disc present = Likely true gynecomastia
- Soft tissue only = Likely pseudogynecomastia
- Both present = Mixed gynecomastia (Most common)
Gynecomastia is frequently mistaken for pseudogynecomastia, especially in obese men.
"Because pseudogynecomastia and gynecomastia present similarly in terms of appearance, getting an accurate diagnosis from an experienced doctor is essential to determine the right approach to treatment. During the clinical evaluation, the doctor will assess the severity and gyno grade and recommend an appropriate approach," explains Dr Ivan Puah, who has over 20 years of experience treating gynecomastia and pseudogynecomastia in patients from all walks of life.
What Causes Gynecomastia vs. Chest Fat
Both pseudogynecomastia and gynecomastia can cause a similar appearance of an enlarged, puffy chest. However, the key difference lies in their underlying causes.
Gynecomastia Causes
Gynecomastia often results from hormonal imbalances, though the exact cause can sometimes be idiopathic, meaning it occurs without a clear explanation.
This medical condition affects 1 out of 2 teen boys and 2 out of 3 men above 50 years old.
Understanding that obesity is not the sole cause of gynecomastia is crucial. By being aware of the variety of reasons that can make any male susceptible to this condition, you are empowered to take control of your health.
- Age-related changes
- Side effects of taking certain medications
- Using anabolic steroids for bodybuilding
- Malnutrition and starvation
- Underlying medical conditions such as kidney or liver diseases, lung cancer, cancer of the pituitary gland, adrenal glands or testicles, including thyroid disorders.
Unlike pseudogynecomastia, glandular tissue does not respond to diet, exercise, or non-invasive treatments such as fat freezing or low-energy laser therapy.
Pseudogynecomastia Causes
"Pseudo" means false or imitation, resulting from the accumulation of chest fat. Genetically, men tend to accumulate fat in the chest and abdominal area. When chest fat builds up, the chest appears puffy and swollen.
This is clinically known as lipomastia or adipomastia. The more estrogen you have, the more your body stores fat. Fat also causes your body to produce the aromatase enzyme, which can convert testosterone into estrogen and slow metabolism.
Unfortunately, a lower metabolism will also mean you burn less fat, which triggers a vicious cycle where you store more and more fat in your chest area.
Can You Have Both? (Mixed Gynecomastia)
Interestingly, pseudogynecomastia, caused by fat rather than glandular tissue, is less common than gynecomastia.
Dr Ivan Puah noted that many who initially thought they had pseudogynecomastia were actually diagnosed with true or mixed gynecomastia after a medical evaluation, highlighting the importance of seeking professional assessment to understand your condition accurately.
To successfully treat mixed gynecomastia, combining surgical gland excision and liposuction during treatment is necessary to result in the best masculine male.
For pseudogynecomastia, liposuction alone can give you great results.
When to See a Doctor
While some try to combat these issues with chest exercises or dieting, these methods often prove ineffective. To know if you are suffering from gyno or pseudogynecomastia, the first step is to schedule an assessment with Dr Ivan Puah for an accurate diagnosis.

Liposuction For Pseudogynecomastia (Fat Only): How it works
Dr Ivan Puah's MDC-Sculpt® ️Lipo technique is a novel liposuction method that is tailored to suit each individual's distinct chest shape, fat distribution, and skin laxity.
This approach utilises specialised lipo cannulas. to target fat layers from multiple dimensions to sculpt the chest and encourages skin tightening, a result that traditional liposuction often struggles to achieve.
It results in minimal surgical scarring, a faster recovery period, and a natural, well-contoured masculine chest.

After carefully excising the enlarged glandular tissue with 360°GTD®, Dr Puah will remove the excess fat with the MDC-Sculpt® Lipo Technique while contouring and flattening the chest area.
Scarring is minimal, and the risk of haematoma is significantly reduced with Dr Puah's proprietary methods.
FAQ on gynecomastia and pseudogynecomastia
How do I know if I have gynecomastia or just fat?
Pseudogynecomastia (excess chest fat) is primarily due to fat accumulation, while gynecomastia involves the enlargement of male breast tissue (glandular with or without excess chest fat). To understand what you are experiencing, you can do the self-pinch test or schedule an appointment with a doctor for an accurate diagnosis.
Will losing weight get rid of gynecomastia?
In theory, exercise and weight loss can improve excess chest fat. However, many patients find that the fat tissue is often resistant to these efforts. If diet and exercise do not yield the desired results, medical evaluation and potential treatment options, such as male chest liposuction, may be necessary.
Can gynecomastia go away on its own?
Gynecomastia may resolve on its own, but once developed, especially in adulthood, it does not go away on its own.
What does gynecomastia feel like?
For men suffering from gynecomastia, the breasts appear more rounded, and the nipples tend to appear swollen or puffy. This condition is often accompanied by tenderness and discomfort, which may worsen over time.
Is gynecomastia dangerous?
Gynecomastia and pseudogynecomastia may not pose health risks, but they can take a toll on self-esteem. Many men feel self-conscious about their chests, and severe cases may lead to bullying or teasing due to what some refer to as "man boobs.
At what age does gynecomastia go away?
In most cases, the breast enlargement resolves on its own within a few weeks or months after birth. Some males experience it during puberty, but it resolves independently within a few months or one to two years. If you experience it during adulthood, gynecomastia may not resolve on its own.
Can I diagnose gynecomastia at home?
You can do a pinch test at home. Still, an accurate diagnosis should always be made by an experienced gynecomastia doctor who performs gynecomastia surgery regularly, often monthly, for patients from all walks of life.
Do I need an ultrasound to diagnose gynecomastia?
Ultrasound is not required for an accurate diagnosis of gynecomastia. However, it may be necessary if the lump feels suspicious and the doctor recommends it to rule out cancer or other malignancies.
