European results of assisted reproductive techniques from treatments initiated during 1997 are presented in this first ESHRE report. Data were collected from 18 European countries, usually from already-existing national registers. A total of 482 clinics from these 18 countries reported 203 893 cycles. In 10 countries with complete registration, 133215 cycles were performed in a population of 174 million, corresponding to 765 cycles per million inhabitants. After IVF and intracytoplasmic sperm injection (ICSI), the distribution of transfer of one, two, three and four or more embryos was 11.5, 35.9, 38.4 and 14.3% respectively. Huge differences existed between countries. For IVF, the clinical pregnancy rate per transfer was 26.1%, and the delivery rate per embryo transfer 20.9%. For ICSI, the corresponding rates were 26.4% and 21.5%. Singleton, twin, triplet and quadruplet delivery rates for IVF were 70.4, 25.8, 3.6 and 0.2% respectively, giving a total multiple delivery rate for IVF of 29.6%. After ICSI, the corresponding rates were 71.7, 25.2, 2.9 and 0.1%, amounting to a total multiple delivery rate of 28.2%. The range of triplet delivery rates after IVF range from 0.4% to 11.9% among countries.
