MULTICENTER APPROACHES TO DONOR INSEMINATION IN THE FRENCH CECOS FEDERATION - NATIONWIDE EVALUATION, DONOR MATCHING, SCREENING FOR GENETIC-DISEASES AND CONSANGUINITY

The French CECOS Federation collates the results of its 22 sperm banks and provides annual reports on their activity. These records allow st udies on many different aspects; annual nationwide evaluation, matchin g of donors and recipients, follow-up of pregnancies, research into ar tificial procreation, and natural fertility. Risk of transmitted hered itary disease is minimised by genetic screening which establishes the genealogy of donor candidates and includes karyotyping and other biolo gical investigations when a particular risk is suspected. The real ris k of consanguinity is very small. Limiting the number of children born from a given sperm donor can be defined at the local level.
