The European Centre for Disease Prevention and Control was asked by the European Commission to assess the risk involved in changing the testing requirements for HIV (human immunodeficiency virus), hepatitis B virus (HBV), and hepatitis C virus (HCV) with regard to the quality and safety of non-partner semen donations.
In May 2011, the European Commission asked ECDC to estimate the change in total exposure risk to hepatitis B (HBV), hepatitis C (HCV) and human immunodeficiency virus (HIV) during reproductive cell handling and storage for secondary parties, if the current scheme of testing at each cell donation would change to testing partner donors of reproductive cells once or twice a year.
