The International Committee for Monitoring Assisted Reproductive Technology's (ICMART) Eighth World Report analyzes assisted reproductive technology (ART) practice and results for the year 2002 from 53 countries by type of ART, women's age, number of embryos transferred and multiple births. Over 601,243 initiated cycles resulted in a delivery rate (DR) per aspiration of 22.4% for conventional IVF, 21.2% for ICSI and a DR per transfer of 15.3% for frozen embryo transfer. For conventional IVF and ICSI, there was an overall twin rate of 25.7% per delivery and a triplet rate of 2.5%. The number of babies born worldwide through ART in 2002 was estimated to range between 219,000 and 246,000. There were wide variations in availability, DRs and multiple birth rates across the countries. Compared with the previous report (year 2000), there was a large increase in the number of cycles and a slight increase in the DR. There was a marginal decline in the mean number of embryos transferred and in the multiple DRs.
