Explanation of Figures 42–43. Click on titles or images to go back to Section 3.
Figure 42: What is the percentage of transfers that result in live births and singleton live births for ART cycles using frozen nondonor embryos?
Figure 42 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, 2007.
- Frozen Embryos is subdivided into the following three categories:
- Thawed embryos resulting in live births, 29.3%
- Transfers resulting in live births, 29.9%
- Transfers resulting in singleton live births, 22.7%
- Fresh Embryos is subdivided into the following two categories:
- Transfers resulting in live births, 35.9%
- Transfers resulting in singleton live births, 24.7%
Figure 43: What is the risk of having a multiple-fetus pregnancy or multiple-infant live birth from an ART cycle using frozen nondonor embryos?
Figure 43 depicts two pie charts, A and B, representing the risks of having a multiple-fetus pregnancy and multiple-infant live birth from ART cycles using frozen nondonor embryos, 2007.
- Pie chart A represents 8,111 pregnancies
- Singletons: 66.3%
- Total multiple-fetus pregnancies 24.0%, which is subdivided as follows:
- Twins: 21.3%
- Triplets or more: 2.7%
- Not able to determine number of fetuses because the pregnancy ended in an early miscarriage: 9.8%
Note: Total does not equal 100% due to rounding.
- Pie chart B represents 6,365 live births
- Singletons: 75.9%
- Total multiple-infant live births 24.1%, which is subdivided as follows:
- Twins: 22.7%
- Triplets or more: 1.4%
