Abstract

BACKGROUND This 12th European IVF-monitoring (EIM) report presents the results of treatments involving assisted reproductive technology (ART) initiated in Europe during 2008. METHODS From 36 countries (3 more compared with 2007), 1051 clinics reported 532 260 treatment cycles including: IVF (124 539), ICSI (280 552), frozen embryo replacements (FER, 97 120), egg donation (ED, 13 609), in vitro maturation (IVM, 562), preimplantation genetic diagnosis/screening (PGD/PGS, 2875) and frozen oocyte replacements (FOR, 4080). Overall, this represents a 7.9 increase in the activity since 2007, which is mainly related to an increase in cycles from almost all registers and only partially to the new countries entering EIM (Estonia, Kazakhstan, Moldova and Romania, 5480 cycles in total). European data on intrauterine insemination using husband/partner's (IUI-H) and donor (IUI-D) semen were reported from 27 and 21 countries, respectively. A total of 144 509 IUI-H (1.5) and 24 960 IUI-D (-4.3) cycles were included. RESULTS In 19 countries where all clinics reported to the ART register, a total of 350 143 ART cycles were performed in a population of 369.8 million, corresponding to 947 cycles per million inhabitants. For IVF, the clinical pregnancy rates per aspiration and per transfer were 28.5 and 32.5, respectively, and for ICSI the corresponding rates were 28.7 and 31.9. In FER cycles, the pregnancy rate per thawing was 19.3. The delivery rate after IUI was 9.1 for IUI-H and 13.8 for IUI-D. In IVF and ICSI cycles, one, two, three and four or more embryos were transferred in 22.4, 53.2, 22.3 and 2.1, respectively. The proportions of singleton, twin and triplet deliveries after IVF and ICSI (combined) were 78.3, 20.7 and 1.0, respectively, resulting in a total multiple delivery rate of 21.7, compared with 22.3 in 2007, 20.8 in 2006 and 21.8 in 2005. In FER cycles, the multiple delivery rate was 13.7 (13.4 twins and 0.3 triplets). In women undergoing IUI, twin and triplet deliveries occurred in 10.6 and 0.7 with IUI-H and in 9.4 and 0.3 with IUI-D, respectively. CONCLUSIONS In comparison with previous years, there was an increase in the reported number of ART cycles in Europe. For the first time in 5 years, the pregnancy rates failed to show a year-on-year increase. Compared with 2007, the number of transfers of multiple embryos (3) and a multiple delivery rate showed a marginal decline.
