Percentages of transfers using fresh embryos from fresh donor or fresh nondonor eggs that resulted in live births, by age of woman, 2019

The above figure compares percentages of transfers resulting in live births for ART cycles using fresh embryos from donor eggs with those for ART cycles using a woman's own eggs, among women of different ages. The likelihood of a fertilized egg implanting is related to the age of the woman who produced the egg. Thus, the percentage of transfers resulting in live births for cycles using embryos from women's own eggs declines as women get older. By contrast, since egg donors are typically in their 20s or early 30s, the percentage of transfers resulting in live births for cycles using embryos from donor eggs remained consistently high at above 40%.
