What are the success rates for ART cycles using frozen nondonor embryos? Figure 33

Figure 33 is a bar graph representing success rates for frozen embryos and fresh embryos, 2002.

• Frozen Embryos (subject heading is divided into the following three categories):
  • Live births per thaw, 24.1%
  • Live births per transfer, 24.8%
  • Singleton live births per transfer, 18.7%
• Fresh Embryos (subject heading is divided into the following two categories):
  • Live births per transfer, 34.8%
  • Singleton live births per transfer, 22.5%

What is the risk of having a multiple-fetus pregnancy or multiple-infant birth from an ART cycle using frozen nondonor embryos? Figure 34

Figure 34 depicts two pie charts, A and B, representing the risk of having a multiple-fetus pregnancy and multiple-infant live birth from ART cycles using frozen nondonor embryos, 2002.

Pie chart A represents 4,562 pregnancies

• Singletons: 68.0%
• Total multiple-fetus pregnancies 24.5%, which are further subdivided as follows:
  • Twins: 20.3%
  • Triplets or more: 4.2%
  • Not able to determine because the pregnancy ended in miscarriage: 7.5%

Pie chart B represents 3,619 live births

• Singletons: 75.4%
• Total multiple-infant live births 24.6%, which are further subdivided as follows:
  • Twins: 22.3%
  • Triplets or more: 2.3%
