Pregnancy Success Rates Using Donor Eggs



Cute babyIn the United States, the CDC (Centers for Disease Control) collects data from fertility clinics on their pregnancy success rates for infertility treatments such as IVF, PCG, and ICSI. In these surveys, the pregnancy success rate is defined as the percentage of a particular treatment that results in a pregnancy and live birth. Recently I have received numerous questions about the pregnancy rates using donor eggs, so I thought I would do some research. Since the CDC takes some time to analyze the data, the most recent CDC data comes from 2004. I’ve summarized the results below.

Success Rates for IVF (in vitro fertilization) Using Donor Eggs

  • There were a total of 9,283 ART cycles using fresh embryos conceived from donor eggs. The success rate was 50.5 percent, meaning that 4,641 ART cycles resulted in a pregnancy with a live birth.
  • There were a total of 4,439 ART cycles using frozen embryos concieved from donor eggs. The success rate was 30.5 percent, meaning that 1,331 ART cycles resulted in a pregnancy with a live birth.

    For both types of embryo transfers, the average number of embryos transferred per cycle was between 2.4 and 2.7.

    If you are having your baby through egg donation, you should definitely ask your doctor about the differences between using fresh and frozen embryos.
