Figure 43 is a bar graph representing percentages of embryos transferred that resulted in implantation among women using frozen nondonor embryos, by age group, 2009.
- Age <35, 25.2%
- Age 35–37, 21.4%
- Age 38–40, 18.0%
- Age 41–42, 14.7%
- Age 43–44, 10.9%
- Age >44, 10.6%
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, 2009.
- Frozen embryos is subdivided into the following three categories:
- Thawed embryos resulting in live births, 30.3%
- Transfers resulting in live births, 30.8%
- Transfers resulting in singleton live births, 23.6%
- Fresh embryos is subdivided into the following two categories:
- Transfers resulting in live births, 36.6%
- Transfers resulting in singleton live births, 25.5%
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, 2009.
- Pie chart A represents 9,487 pregnancies.
- Singletons: 67.3%
- Total multiple-fetus pregnancies 22.8%, which is subdivided as follows:
- Twins: 20.9%
- Triplets or more: 1.9%
- Not able to determine number of fetuses: 9.8%
Note: Total does not equal 100% due to rounding.
- Pie chart B represents 7,424 live births.
- Singletons: 76.6%
- Total multiple-infant live births 23.4%, which is subdivided as follows:
- Twins: 22.3%
- Triplets or more: 1.1%
