BACKGROUND: Results of assisted reproductive techniques from treatments initiated in Europe during 2005 are presented in this ninth report. Data were mainly collected from existing national registers. METHODS: From 30 countries, 923 clinics reported 418 111 treatment cycles including: IVF (118 074), ICSI (203 329), frozen embryo replacement (79 140), oocyte donation (ED, 11 475), preimplantation genetic diagnosis/screening (5846) and in vitro maturation (247). Overall, this represents a 13.6% increase since 2004, partly due to inclusion of 28 417 cycles from Turkey. European data on intrauterine insemination using husband/partner's semen (IUI-H) and donor semen (IUI-D) were reported from 21 countries and included 128 908 IUI-H and 20 568 IUI-D cycles. RESULTS: In 16 countries where all clinics reported to the IVF register, 1115 cycles were performed per million inhabitants. For IVF, the clinical pregnancy rates per aspiration and per transfer were 26.9% and 30.3%, respectively. For ICSI, the corresponding rates were 28.5% and 30.9%. After IUI-H, the clinical pregnancy rate was 12.6% per insemination in women <40. After IVF and ICSI, the distribution of transfer of one, two, three and four or more embryos was 20.0%, 56.1%, 21.5% and 2.3%, respectively. Huge differences exist between countries. The distribution of singleton, twin and triplet deliveries after IVF and ICSI was 78.2%, 21.0% and 0.8%, respectively. This gives a total multiple delivery rate of 21.8% compared with 22.7% in 2004 and 23.1% in 2003. In women <40 years of age, IUI-H was associated with a twin and triplet pregnancy rate of 11.0% and 1.1%, respectively. CONCLUSIONS: Compared with earlier years, there was an increase in the reported number of ART cycles in Europe. Although fewer embryos were transferred per treatment, there was a marginal increase in pregnancy rates and a reduction in multiple deliveries.
