Gynaecomastia vs Pseudogynaecomastia

“Gynaecomastia” and “pseudogynaecomastia” are terms used to describe different conditions related to the enlargement of male breast tissue. These terms refer to distinct underlying causes and characteristics. Here’s a detailed comparison between gynaecomastia and pseudogynaecomastia:


  • Cause: Gynaecomastia is the development of actual breast glandular tissue in males due to an imbalance in hormones, particularly an increase in estrogen relative to testosterone.
  • Tissue Composition: Gynaecomastia involves the growth of glandular breast tissue, similar to what is found in females.
  • Appearance: It leads to a rubbery or firm mass of tissue, often located just under the nipple. The breast tissue may be tender or sensitive.
  • Causes: Gynaecomastia can be caused by hormonal changes during puberty, aging, certain medical conditions (such as hormonal imbalances, liver disease, and kidney disease), medications (such as anti-androgens, some antipsychotics, and certain medications for prostate issues), and recreational drug use (e.g., marijuana, anabolic steroids).
  • Treatment: Treatment depends on the underlying cause. In some cases, gynaecomastia may resolve on its own, such as during puberty. In persistent cases or those causing distress, surgical removal of excess breast tissue (mastectomy) may be considered.


  • Cause: Pseudogynaecomastia, often referred to as “false gynaecomastia,” is characterized by the accumulation of excess fat in the chest area without significant growth of glandular tissue.
  • Tissue Composition: It primarily involves an accumulation of adipose (fat) tissue in the chest.
  • Appearance: Pseudogynaecomastia results in a softer and less firm appearance compared to true gynaecomastia. The chest may appear to have more fatty tissue.
  • Causes: Pseudogynaecomastia is commonly associated with obesity and weight gain. The accumulation of excess body fat in the chest area can give the appearance of enlarged breasts.
  • Treatment: The primary treatment for pseudogynaecomastia involves weight loss through a combination of a healthy diet and regular exercise. Reducing overall body fat can lead to a reduction in chest fat.

It’s important to note that both gynaecomastia and pseudogynaecomastia can affect an individual’s self-esteem and body image. If you are concerned about changes in your chest or any related health issues, it’s recommended to consult with a medical professional. They can provide a proper diagnosis, guidance on potential causes, and recommendations for appropriate management or treatment options based on your individual circumstances.
