Figure 38 contains two pie charts (A & B) representing the risk of having multiple-fetus pregnancy and multiple-infant live birth from ART cycles using fresh embryos from donor eggs, 2001.

Chart A represents 4,302 pregnancies, of which 43.6% are multiple-fetus pregnancies.
These 4,302 pregnancies are further broken down as follows:

• Singletons: 52.3%
• Twins: 35.5%
• Triplets or more: 8.1%
• Not able to determine number of fetuses because the pregnancy ended in miscarriage: 4.1%

Chart B represents 3,629 live births, of which 41.7% are multiple-infant live births.
These 3,629 live births are further broken down as follows:

• Singletons: 58.3%
• Twins: 38.4%
• Triplets or more: 3.3%

Figure 39 is a bar graph representing the success rates in terms of live births and singleton live births per transfer for ART cycles using frozen donor embryos and for those using fresh donor embryos, 2001.

• Frozen donor embryos
  • Live births per transfer, 27.3%
  • Singleton live births per transfer, 19.6%

• Fresh donor embryos
  • Live births per transfer, 47.0%
  • Singleton live births per transfer, 27.4%
