Percentages of ART cycles using fresh nondonor eggs or embryos that resulted in pregnancies, live births, and singleton live births among women aged 40 or older,* 2006

Success rates decline with each year of age and are particularly low for women 40 or older. The above figure shows the percentages of pregnancies, live births, and singleton live births in 2006 for women 40 or older who used fresh nondonor eggs or embryos. The average chance for pregnancy was 23 percent for women age 40; the percentage of ART cycles resulting in live births for this age was about 15 percent, and the percentage of ART cycles resulting in singleton live births was about 12 percent. All percentages dropped steadily with each 1-year increase in age. For women older than 44, the percentages of live births and singleton live births were both a little more than 1 percent. Women 40 or older generally have much higher success rates using donor eggs.
