Although ART clinics are located throughout the United States, generally in or near major cities, the greatest number of clinics is in the eastern United States. Figure 1 shows the locations of the 391 reporting clinics. The fertility clinic section of this report, arranged in alphabetical order by state, city, and clinic name, provides specific information on each of these clinics. The number of clinics, cycles performed, live-birth deliveries, and live babies born as a result of ART all have increased steadily since CDC began collecting this information in 1995 (see Section 5). Because in some cases more than one infant is born during a live-birth delivery (e.g., twins), the total number of live babies born is greater than the number of live-birth deliveries. CDC estimates that ART accounts for slightly more than 1% of total U.S. births.

For slightly more than 74% of ART cycles carried out in 2002, fresh nondonor eggs or embryos were used. ART cycles that used frozen nondonor embryos were the next most common type, accounting for approximately 14% of the total. In about 11% of cycles, eggs or embryos were donated by another woman. A very small number of cycles (less than 1% of the ART cycles carried out in 2002) involved the evaluation of a new treatment procedure. The vast majority of these cycles included pre-implantation genetic diagnosis for screening of genetic disorders, and a few involved the retrieval of immature oocytes. The number of cycles in which a new treatment procedure was being evaluated is not included in the total number of cycles reported in Sections 2 through Section 5 of the national report and in the individual fertility clinic tables. Thus, data presented in subsequent figures in this report and in the individual fertility clinic tables are based on 115,392 ART cycles.
