BACKGROUND This 11th European IVF-monitoring report presents the results of assisted reproductive technology (ART) treatments initiated in Europe during 2007.

METHODS From 33 countries, 1029 clinics reported 493 184 treatment cycles: IVF (120 761), ICSI (256 642), frozen embryo replacement (91 145), egg donation (15 731), preimplantation genetic diagnosis/preimplantation genetic screening (4638), in vitro maturation (660) and frozen oocytes replacements (3607). Overall, this represents a 7.6% increase since 2006, mostly related to an increase in all registers. IUI using husband/partner's (IUI-H) and donor (IUI-D) semen was reported from 23 countries: 142 609 IUI-H (+6.2%) and 26 088 IUI-D (+7.2%).

RESULTS In 18 countries where all clinics reported, 376 971 ART cycles were performed in a population of 425.6million (886 cycles per million). The clinical pregnancy rates per aspiration and per transfer were 29.1 and 32.8% for IVF, and 28.6 and 33.0% for ICSI. Delivery rate after IUI-H was 10.2% in women aged < 40 years. In IVF/ICSI cycles, 1, 2, 3 and =4 embryos were transferred in 21.4, 53.4, 22.7 and 2.5% of cycles, with no decline in the number of embryos per transfer since 2006. The proportion of multiple deliveries (22.3: 21.3% twin and 1.0% triplet), did not decrease compared with 2006 (20.8%) and 2005 (21.8%). In women < 40 years undergoing IUI-H, twin deliveries occurred in 11.7% and triplets in 0.5%.

CONCLUSIONS In comparison with previous years, the reported number of ART cycles in Europe increased in 2007; pregnancy rates increased marginally, but the earlier decline in the number of embryos transferred and multiple births did not continue.
