Gynecomastia is an enlargement of the mammary gland in men. We distinguish:

  1. True gynecomastiamammary gland proliferation;
  2. Pseudogynekomastia – increased fat in the breast area;


  • in newborns;
  • in puberty;
  • in men going into a senium.



The course of surgical removal

Gynecomastia in men can also be removed surgically by performing a plastic operation, where an incision is made around the areola. This operation takes place under general anaesthesia.[3]
