Objective: To summarize the procedures and outcomes of ART initiated in the United States in 2000. Design: Data were collected electronically using the SART Clinical Outcome Reporting System software and submitted to the American Society for Reproductive Medicine/Society for Assisted Reproductive Technology Registry. Participant(s): Three hundred eighty-three programs submitted data on procedures performed in 2000. Data were collated after November 2000 so that the outcome of all pregnancies established would be known. Main Outcome Measure(s): Incidence of clinical pregnancy, ectopic pregnancy, abortion, stillbirth, and delivery. Result(s): Programs reported initiating 99,989 cycles of ART treatment. Of these, 73,406 cycles involved fresh nondonor IVF (46.6% with intracytoplasmic sperm injection [ICSI]), with a delivery rate per retrieval of 29.9%; 549 were cycles of gamete intrafallopian transfer, with a delivery rate per retrieval of 24.7%; 763 were cycles of zygote intrafallopian transfer, with a delivery rate per retrieval of 29.9%. The following additional ART procedures were also initiated: 7,581 fresh donor oocyte cycles, with a delivery rate per transfer of 43.7%; 13,083 frozen embryo transfer procedures, with a delivery rate per transfer of 20.4%; 2,721 frozen embryo transfers using donated oocytes or embryos, with a delivery rate per transfer of 23.5%, and 1,200 cycles using a host uterus, with a delivery rate per transfer of 35.8%. In addition, 326 cycles were reported as combinations of more than one treatment type, 41 cycles as research, and 319 as embryo banking. As a result of all procedures, 25,394 deliveries were reported, resulting in 35,345 neonates, of which 35,031 were live born and 314 stillborn. Conclusion(s): In 2000, there were more programs reporting ART treatment and a significant (13.5%) increase in reported cycles compared to 1999. In comparable cycle types, overall success rate (deliveries per retrieval) exhibited an actual increase of 0.6%, which represents an increase of 2.2% when compared to the success rate for 1999.
