Introduction to the 2010 National Report
Data provided by United States 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 healthy 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 when using ART are influenced by many factors, some of which are patient-related and outside a clinic’s control (e.g., the woman’s age, the cause of infertility). Because the national data set includes information on many of these factors, it can give potential ART users an idea of the 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 443 fertility clinics in operation in 2010 that provided and verified data on the outcomes of all ART cycles started in their clinics. The 147,260 ART cycles performed at these reporting clinics in 2010 resulted in 47,090 live births (deliveries of one or more living infants) and 61,564 infants. The 2010 National Summary table combines data from all clinics included in the 2010 Assisted Reproductive Technology Fertility Clinic Success Rates Report (hereafter called the 2010 Fertility Clinic Success Rates Report). Read the explanation of how to read this table, of the 2010 Fertility Clinic Success Rates Report.
The national report consists of graphs and charts that use 2010 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 embryos that might have been frozen in previous years, but were thawed and transferred in 2010.
The national report has five sections:
- Section 1 (Figures 1 through 5) presents information from all ART procedures reported.
- Section 2 (Figures 6 through 39) presents information on the ART cycles that used only fresh nondonor eggs or embryos from nondonor eggs or, in a few cases, a mixture of fresh and frozen embryos from nondonor eggs (100,824 cycles resulting in 82,624 transfers).
- Section 3 (Figures 40 through 42) presents information on the ART cycles that used only frozen embryos from nondonor eggs (28,425 cycles resulting in 26,241 transfers).
- Section 4 (Figures 43 through 47) presents information on the ART cycles that used only donated eggs or embryos (18,011 cycles resulting in 16,531 transfers).
- Section 5 (Figures 48 through 60) presents trends in the number of ART procedures and success rates over the past 10 years, from 2001 through 2010.
