TH2.H1.6 Male Breast

Male Breast:

  • The breast in the male is rudimentary
  • The male breast usually has no fat, additional to that of the superficial fascia which covers the anterior thorax
  • Deep to the rudimentary nipple and the areola, there is a rudimentary duct system
  • Although normally, the duct system in the male is rudimentary, it remains responsive to the female sex hormone, oestrogen
  • Expansion of breast glandular tissue may occur as a result of an endocrine disorder or from exogenous oestrogen present in medications or in environmental pollutants
