CDC Assisted Reproductive Technology (ART) Success Rates
Fertility clinics in the U.S. report and verify data on the assisted reproductive technology (ART) cycles started and carried out in their clinics, and the outcomes of these cycles, during each calendar year. ART includes all fertility treatments in which either eggs or embryos are handled. The main type of ART is in vitro fertilization (IVF). IVF involves extracting a woman’s eggs, fertilizing the eggs in the laboratory, and then transferring the resulting embryos into the woman’s uterus through the cervix. These ART data are a rich source of information that can give potential ART users an idea of their average chances of success per ART cycle or ART transfer. Average chances, however, do not necessarily apply to a particular individual or couple. ART success rates vary in the context of patient and treatment characteristics, such as age, infertility diagnosis, number of embryos transferred, type of ART procedure, use of techniques such as ICSI, and history of previous births, miscarriages, and ART cycles. People considering ART should consult a physician to discuss their treatment options.
