Where are U.S. ART clinics located, how many ART cycles did
they perform in 2003, 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 399 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 infants 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 infants 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 2003?
For 74% of ART cycles carried out in 2003, 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 12% 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 2003) 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 122,872 ART cycles.
