Section 3: ART Cycles Using Frozen Nondonor Embryos
Explanation of Figures 43–45. Click on titles or images to go back to Section 3.
Figure 43 is a bar graph representing percentages of embryos transferred resulting in implantation among women using frozen nondonor embryos, by age group, 2008.
- Age <35, 24.3%
- Age 35–37, 20.5%
- Age 38–40, 17.2%
- Age 41–42, 12.9%
- Age 43–44, 9.7%
- Age >44, 9.5%
Figure 44 is a bar graph representing percentages of transfers that resulted in live births and singleton live births for ART cycles using frozen nondonor embryos and ART cycles using fresh nondonor embryos, 2008.
- Frozen embryos is subdivided into the following three categories:
- Thawed embryos resulting in live births, 30.0%
- Transfers resulting in live births, 30.6%
- Transfers resulting in singleton live births, 23.6%
- Fresh embryos is subdivided into the following two categories:
- Transfers resulting in live births, 36.7%
- Transfers resulting in singleton live births, 25.1%
Figure 45 depicts two pie charts, A and B, representing risks of having multiple-fetus pregnancies and multiple-infant live births from ART cycles using frozen nondonor embryos, 2008.
- Pie chart A represents 9,164 pregnancies.
- Singletons: 66.8%
- Total multiple-fetus pregnancies 23.5%, which is subdivided as follows:
- Twins: 20.8%
- Triplets or more: 2.7%
- Not able to determine number of fetuses: 9.6%
- Note: Total does not equal 100% due to rounding.
- Pie chart B represents 7,123 live births.
- Singletons: 77.1%
- Total multiple-infant live births 22.9%, which is subdivided as follows:
- Twins: 21.5%
- Triplets or more: 1.4%
