Where
are U.S. ART clinics located, how many ART cycles did they perform in
2001, and how many infants were born?
Although
ART clinics are located throughout the United States, the greatest number
of clinics is in the eastern United States. Most clinics are in or near
major cities. Figure 1 shows the locations of the 384 reporting clinics.
The fertility clinic section of this report, 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 approximately 1% of total
U.S. births.

What types of ART procedures were used in the United
States in 2001?
For slightly more than 75% of the 107,587
ART cycles carried out in 2001, 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 11% of
cycles, eggs
or embryos were donated by another woman.
