title: Donor deferral policies for men who have sex with men: where are we today?
abstract: The review summarizes recent publications on the contentious issue of donor deferral criterion for men who have sex with men (MSM).
  
  
  
  Recent studies from the United States and China demonstrated that MSM is still a frequent risk factor for HIV-positive donors. Noncompliance is an important factor in the overall risk of HIV transmission but does not appear to be affected by the length of the deferral period. A major US study found a 2.6% noncompliance rate with the current indefinite deferral for MSM; similar or lower rates were found in other jurisdictions with shorter deferral periods. Several countries have had a defined deferral period of 1 year or 5 years in place long enough to determine that increases in HIV-positive cases predicted by modeling studies did not actually occur, suggesting that the assumptions made in these models are overly conservative.
  
  
  
  In summary, MSM eligibility policies are slowly changing around the world, with the US FDA now permitting a 1-year deferral. Transparency, involvement of stakeholders, and careful evaluation of risk and societal benefit should be part of future policy discussions on this issue.
