Preparing for infertility treatment and pregnancy requires extra time and effort. Learn more about what you can do to be healthy before, during, and after ART treatment. Being in good health also may increase the chance of pregnancy and giving birth to a healthy baby.

Using the ART Report

In the United States, more than 440 clinics provide services to patients seeking to overcome infertility. CDC’s annual Assisted Reproductive Technology (ART) Clinic Success Rates Report  is one tool consumers can use to identify clinics offering medical care and other services. The report provides an in-depth picture of the ART procedures performed in U.S. fertility clinics and information about outcomes of these procedures. It includes individual clinic tables that provide ART success rates and other information from each clinic.

IVF Success Estimator

Another tool to estimate the chance of having a live birth using in vitro fertilization (IVF)—the most common type of Assisted Reproductive Technology (ART)—is the IVF Success Estimator. This information is calculated based on the experiences of women and couples with similar characteristics using National ART Surveillance System.

Selecting a Provider

Selecting a fertility clinic and ART provider that will address your specific needs can be difficult. You can find information about each fertility clinic in CDC’s annual Assisted Reproductive Technology (ART) Clinic Success Rates Report. To select a fertility clinic in your state, you can also use the Interactive Clinic Tables to view the clinic profiles, services, and success rates for the latest reporting year, as well as for previous reporting years. We also recommend that you ask questions to help you learn more about the fertility clinic, its services, and staff.

Single Embryo Transfer

Fertility treatments often result in multiple births (birth of two or more infants). It is important to know that carrying and delivering twins and higher order multiples is associated with higher risk of complications for both women and infants. The decisions that you and your provider make while going through fertility treatments may affect your and your infant’s health. The American Society for Reproductive Medicine (ASRM) and Society for Assisted Reproductive Technology (SART) have released guidance on the number of embryos to transferexternal icon to reduce the chances of having a multiple birth that you may wish to discuss with your physician.
