Percentage of embryo transfers that resulted in live-birth delivery, by patient age and egg or embryo source, United States, 2020

The above figure shows the percentage of embryo transfer cycles started in 2020 that resulted in live-birth delivery of one or more live infants, by patient age and egg or embryo source.

Fresh and frozen eggs or embryos from patients and donors are included. Banking cycles are excluded.

The percentage of embryo transfer cycles that used patient eggs or embryos and resulted in live-birth delivery generally decreased as the age of the woman increased (range: 10.6 to 42.7%) because the likelihood of a fertilized egg implanting is related to the age of the woman who produced the egg. In contrast, 41.4% of embryo transfer cycles using donor eggs or embryos resulted in live-birth delivery for women of all ages (range: 37.6 to 48.5%) because egg donors are typically in their 20s or early 30s and do not have infertility.
