2003 National Summary Table | 2003 National Summary Accessible Table

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 399 fertility clinics in operation in 2003 that
provided and verified data on the outcomes of all ART cycles started in their clinics. The
122,872 ART cycles performed at these reporting clinics in 2003 resulted in 35,785 live
births (deliveries of one or more living infants) and 48,756 infants.

The national report consists of graphs and charts that use 2003 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 2003.

The national report has five sections:

• Section 1 (Figures 1 and 2) presents information from all ART procedures reported.
• Section 2 (Figures 3 through 35) presents information on the 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 (91,032 cycles resulting in 74,296 transfers).
• Section 3 (Figures 36 and 37) presents information on the ART cycles that used only frozen embryos from nondonor eggs (17,517 cycles resulting in 15,725 transfers).
• Section 4  (Figures 38 through 42) presents information on the ART cycles that used only donated eggs or embryos (14,323 cycles resulting in 12,996 transfers).
• Section 5 (Figures 43 through 49) presents trends in the number of ART procedures and success rates from 1996 through 2003.
