title: A taxonomy of possible reasons for and against sperm donation.
abstract: OBJECTIVE
  Various reasons may guide the decision of men to become a sperm donor. Our aim was to identify a comprehensive set of possible reasons for and against sperm donation.
  
  
  METHODS
  Concept mapping.
  
  
  METHODS
  Assisted reproduction clinics.
  
  
  METHODS
  Nine sperm donors and seven non-sperm donors.
  
  
  METHODS
  Interviews to obtain statements for and against sperm donation, card-sorting tasks to categorize these statements according to similarity, and hierarchical cluster analysis to structure these categorizations.
  
  
  METHODS
  Hierarchical structure with reasons for and against sperm donation.
  
  
  RESULTS
  The hierarchical structure with 91 reasons comprised selfishness (including narcissism and procreation), psychosocial drives (including altruism, detached procreation, and sexual/financial satisfaction), and psychosocial barriers (including normative and moral barriers related to oneself, one's spouse, the donor child, and society).
  
  
  CONCLUSIONS
  The identified hierarchical overview of reasons for and against sperm donation may help potential sperm donors when considering becoming a sperm donor, enable more systematic counseling of potential sperm donors, and guide further research on reasons for and against sperm donation.
