Benefit and risk of application of European tissue management regulation in ART.

The application of the European Tissues and Cells Directive requires that a high standard of quality and safety be applied to all tissue establishments, including that of assisted reproductive centres. In the countries where the Directive has been implemented, changes in the ART clinic and laboratory procedures have been made. However, many requirements stipulated in the Directive are already in place in some European countries and are mandatory by the country specific laws, while some other requirements have been recently implemented. In this article the benefits and the potential risks of the Directive implementation on the efficacy, safety and cost of all the different assisted reproductive technologies performed, including cryopreservation techniques and storage policies have been widely analysed. The feasibility of the implementation of some of the specific requirements when considering the delicate issues of reproductive cells in contrast to other cells or tissues covered by the Directive has been evaluated.
