  • The pathologic causes of gynecomastia are diverse and may include Klinefelter syndrome, certain cancers, endocrine disorders, metabolic dysfunction, various medications, or may occur due to a natural decline in testosterone production. (wikipedia.org)
  • Medications such as aromatase inhibitors have been found to be effective in rare cases of gynecomastia from disorders such as aromatase excess syndrome or Peutz-Jeghers syndrome, but surgical removal of the excess tissue is usually required. (wikipedia.org)
  • A small proportion of male gynecomastia cases may be seen with rare inherited disorders such as spinal and bulbar muscular atrophy and the very rare aromatase excess syndrome. (wikipedia.org)
