O-32: Status of Human ART in Spain: Resultsfrom the New Registry of Catalonia

Background: FIVCAT.NET is the registry of human assisted reproductive techniques (ART) in Catalunya to which all authorised centres are obliged to declare their activities. The Background of the present study is to describe the data on effectiveness of the ART in Catalunya over the period 2001-2005 and to compare our findings with other similar registries. Materials and Methods: The data were obtained from the centres conducting ART over this period. All users of the services were included, whether resident or nonresident in Catalunya. Descriptive data of the different stages of the ART process (oocyte recovery, embrio transfer, clinical pregnancy and births) were analysed. The effectiveness of ART was measured by indicators such as rates of pregancy and rate of live birth per pregnancy. Results: An increase (92.4 %) in ART activity over thisperiod was noted. The number of embryos most fre- Abstracts of the 11th Royan International Congress on Reproductive Biomedicine International Journal of Fertility & Sterility (IJFS), Vol 4, Suppl 1, Summer 2010 44 quently transferred changed from three to two. Effectiveness indicators such as pregnancies per transfer improved from 33.2 to 37.1 (from 36.9 to 40.2 using fresh embryos and from to 18.4 to 27.0 with frozen embryos). Multiple births decreased from 50.1 to 38.6, premature births from 37.5 to 28.3 and low-birth-weight infants from 38.0 to 25.6.; findings which compare favourably with other countries .Conclusion: The data collected by FIVCAT.NET are comparable to other surrounding countries, not only with respect to level of activity but also to outcomes achieved.
