Figure 35 is a bar graph representing percentages of embryos transferred that resulted in implantation for ART cycles using frozen nondonor embryos, compared with ART cycles using Fresh nondonor embryos, by age group, 2011.
- Age <35, Frozen nondonor 30.8%, Fresh nondonor 35.6%
- Age 35–37, Frozen nondonor 27.9%, Fresh nondonor 27.3%
- Age 38–40, Frozen nondonor 23.1%, Fresh nondonor 17.3%
- Age 41–42, Frozen nondonor 18.3%, Fresh nondonor 9.4%
- Age 43–44, Frozen nondonor 12.5%, Fresh nondonor 4.5%
- Age >44, Frozen nondonor 12.0%, Fresh nondonor 1.9%
Figure 36 is a bar graph representing percentages of transfers that resulted in pregnancies, live births and singleton live births for ART cycles using frozen nondonor embryos and ART cycles using fresh nondonor embryos, 2011.
- Percentage resulting in pregnancies: Frozen nondonor 44.6%, Fresh nondonor 43.9%
- Percentage resulting in live births: Frozen nondonor 34.5%, Fresh nondonor 35.8%
- Percentage resulting in singleton live births: Frozen nondonor 26.8%, Fresh nondonor 25.6%
Figure 37 depicts two pie charts, A and B, representing distribution of multiple-fetus pregnancies and multiple-infant live births among ART cycles using frozen nondonor embryos, 2011.
- Pie chart A represents 13,325 pregnancies.
- Singletons: 67.6%
- Total multiple-fetus pregnancies 22.7%, which is subdivided as follows:
- Twins: 21.1%
- Triplets or more: 1.6%
- Not able to determine number of fetuses: 9.7%
- Pie chart B represents 10,314 live births.
- Singletons: 77.5%
- Total multiple-infant live births 22.5%, which is subdivided as follows:
- Twins: 21.6%
- Triplets or more: 0.9%
