Where
are U.S. ART clinics located, how many ART cycles did they perform in
2002, and how many infants were born?
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.

What types of ART procedures were used in the United
States in 2002?
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.
