title: New considerations for the pathogenesis of endometriosis.
abstract: OBJECTIVE
  To review the available evidence regarding the immunological, epidemiological and other factors involved in the pathogenesis of endometriosis.
  
  
  METHODS
  Literature review.
  
  
  RESULTS
  Endometriosis remains a poorly-understood disease of unknown etiology and pathogenesis.
  
  
  CONCLUSIONS
  There is evidence to suggest that alterations in the immune response, whether genetically transmitted or environmentally induced, predispose women to the ectopic implantation of endometrial cells transported into the peritoneal cavity by way of retrograde menstruation. This predisposition may exist because of an impaired peritoneal clearing of endometrial cells and fragments or because of pathological angiogenesis.
