Explanation of Figures 6–15. Click on titles or images to go back to Section 2 Part A.


Figure 6 is a bar graph representing outcomes of ART cycles using fresh nondonor eggs or embryos, by stage, 2008.

  • 104,673 cycles started
  • 92,843 retrievals
  • 85,533 transfers
  • 38,631 pregnancies
  • 31,365 live-birth deliveries

Figure 7 is a pie chart representing reasons ART cycles using fresh nondonor eggs or embryos were discontinued in 2008. Note: The statistics below are based on 11,830 ART cycles.

  • No or inadequate egg production 79.8%
  • Patient withdrew for other reasons 14.1%
  • Too-high response to ovarian stimulation medication 5.1%
  • Concurrent illness 1.0%

Figure 8 is a bar graph representing measures of success for ART cycles using fresh nondonor eggs or embryos, 2008.

  • Cycles resulting in pregnancies 36.9%
  • Cycles resulting in live births 30.0%
  • Retrievals resulting in live births 33.8%
  • Transfers resulting in live births 36.7%
  • Cycles resulting in singleton live births 23.1%
  • Transfers resulting in singleton live births 25.1%

Figure 9 is a pie chart representing results of ART cycles using fresh nondonor eggs or embryos, 2008.

  • No pregnancy 62.4%
  • Ectopic pregnancy 0.7%
  • Clinical pregnancy 36.9%, which is subdivided as follows:
    • Single-fetus pregnancy 22.4%
    • Multiple-fetus pregnancy 12.0%
    • Not able to determine the number of fetuses 2.5%

Figure 10 is a pie chart representing outcomes of pregnancies resulting from ART cycles using fresh nondonor eggs or embryos, 2008. Note: Maternal deaths prior to birth are not displayed due to small number (n = 1). Total does not equal 100% due to rounding.

  • Miscarriage 16.5%
  • Induced abortion 1.1%
  • Stillbirth 0.7%
  • Total live births 81.2%, which is subdivided as follows:
    • Singleton birth 55.5%
    • Multiple-infant birth 25.7%
  • Unknown outcome 0.6%
Figure 11 text below

Figure 11 consists of two pie charts, A and B, representing risks of having multiple-fetus pregnancies and the risks of having multiple-infant live births from ART cycles using fresh nondonor eggs or embryos, 2008.

  • Pie chart A represents 38,631 pregnancies.
    • Singletons 60.7%
    • Total multiple-fetus pregnancies 32.5%, which is subdivided as follows:
      • Twins 29.0%
      • Triplets or more 3.5%
    • Not able to determine the number of fetuses 6.8%
  • Pie chart B represents 31,365 live births.
    • Singletons 68.4%
    • Total multiple-infant live births 31.6%, which is subdivided as follows:
      • Twins 29.8%
      • Triplets or more 1.8%

Figure 12 is a bar graph representing percentages of preterm births from ART cycles using fresh nondonor eggs or embryos, by number of infants born, 2008.

  • 12.4% singletons from single-fetus pregnancy were preterm
  • 19.1% singletons from multiple-fetus pregnancy were preterm
  • 60.8% twins were preterm
  • 96.2% triplets or more were preterm

Figure 13 is a bar graph representing percentages of low-birth-weight infants from ART cycles using fresh nondonor eggs or embryos, by number of infants born, 2008.

  • 9.0% singletons from single-fetus pregnancy had low birth weights
  • 14.8% singletons from multiple-fetus pregnancy had low birth weights
  • 55.5% twins had low birth weights
  • 91.9% triplets or more had low birth weights
