2001 National
Summary Accessible Table
Data provided by U.S. clinics that use
assisted reproductive technology (ART) to treat
infertility are a rich source of information about the factors that
contribute to a successful
ART treatment—the delivery of a live-born infant. Pooling the data from
all reporting clinics
provides an overall national picture that could not be obtained by
examining data from an
individual clinic.
A woman’s
chances of having a pregnancy and a live birth by using ART are
influenced by
many factors, some of which (e.g., the woman’s age, the cause of
infertility) are outside a
clinic’s control. Because the national data set includes information on
many of these factors,
it can give potential ART users an idea of their average chances of
success. Average chances,
however, do not necessarily apply to a particular individual or couple. People considering
ART should consult their physician to discuss all the factors that apply in their particular case.
The data for this national report come
from the 384 fertility clinics in operation in 2001 that
provided and verified data on the outcomes of all ART cycles started in
their clinics. The
107,587 ART cycles performed at these reporting clinics in 2001 resulted
in 29,344 live
births (deliveries of one or more living infants) and 40,687 babies.
The national report consists of graphs
and charts that use 2001 data to answer specific
questions related to ART success rates. These figures are organized
according to the type
of ART procedure used. Some ART procedures use a woman’s own eggs, and
others use
donated eggs or embryos. (Although sperm used to create an embryo also
may be either
from a woman’s partner or from a sperm donor, information in this report is presented
according to the source of the egg.) In some procedures, the embryos
that develop are
transferred back to the woman (fresh embryo transfer); in others, the
embryos are frozen
(cryopreserved) for transfer at a later date. This report includes data on frozen embryos
that were thawed and transferred in 2001.
The national report has five sections:
-
Section 1
(Figures 1 and 2) presents information from all ART procedures
reported.
-
Section 2 (Figures 3 through 32) presents information on the
80,864 ART cycles that used
only fresh embryos from nondonor eggs or, in a few cases, a mixture of fresh and frozen
embryos from nondonor eggs.
-
Section 3
(Figures 33 and 34) presents information on the ART cycles that used
only frozen embryos (14,705 cycles resulting in 13,126 transfers).
-
Section 4
(Figures 35 through 39) presents information on the ART cycles that
used only
donated eggs or embryos (12,018 cycles resulting in 10,750 transfers).
-
Section 5
(Figures 40 through 45) presents trends in the number of ART
procedures and
success rates from 1996 through 2001.
The
2001 national
summary table, which is based on data from all clinics included in
this report, immediately precedes
the individual
clinic tables. An explanation of
how to read these tables
is
also provided.
