2007 ART Report Section 2-ART Cycles Using Fresh, Nondonor Eggs or Embryos (Part C)

Figure 27 is a pie chart representing the types of ART procedures using fresh nondonor eggs or embryos, 2007. Note: Cycles that were canceled before egg retrieval were classified as IVF, GIFT, or ZIFT based on the intended ART method. Total does not equal 100% due to rounding.

• IVF without ICSI, 36.5%
• IVF with ICSI, 63.4%
• GIFT, <0.1%
• ZIFT, 0.1%

Figure 32 is a pie chart representing the number of embryos transferred during ART cycles using fresh nondonor eggs or embryos, 2007. Note: Total does not equal 100% due to rounding.

Figure 33 is a bar graph representing percentages of transfers that resulted in live births and percentages of multiple-infant live births for ART cycles using fresh nondonor eggs or embryos, by number of embryos transferred, 2007. Note: In rare cases a single embryo may divide and thus produce twins. For this reason, a small percentage of twins resulted from a single embryo transfer, and a small percentage of triplets resulted when two embryos were transferred. 

• 1 embryo transferred: Percentage of transfers that resulted in live births 20.8%. Of these live births, 97.5% were singletons, 2.4% were twins and 0.1% were triplets or more.
• 2 embryos transferred: Percentage of transfers that resulted in live births 42.6%. Of these live births, 65.9% were singletons, 33.3% were twins and 0.7% were triplets or more.  Note: Total does not equal 100% due to rounding.
• 3 embryos transferred: Percentage of transfers that resulted in live births 34.8%. Of these live births, 66.7% were singletons, 29.4% were twins and 3.9% were triplets or more.

• 5 or more embryos transferred: Percentage of transfers that resulted in live births 25.3%. Of these live births, 73.6% were singletons, 23.4% were twins and 3.0% were triplets or more.

Figure 34 is a bar graph representing percentages of transfers that resulted in live births and percentages of multiple-infant live births for ART cycles in women who were younger than 35, used fresh nondonor eggs or embryos, and set aside extra embryos for future use, by number of embryos transferred, 2007. Note: In rare cases, a single embryo may divide and thus produce twins. For this reason, a small percentage of twins resulted from a single embryo transfer and a small percentage of triplets resulted when two embryos were transferred. 

• 1 embryo transferred: Percentage of transfers that resulted in live births 50.2%. Of these live births, 97.6% were singletons, 2.3% were twins and 0.1% were triplets or more.

• 3 embryos transferred: Percentage of transfers that resulted in live births 50.1%. Of these live births, 55.5% were singletons, 37.2% were twins and 7.3% were triplets or more.
• 4 embryos transferred: Percentage of transfers that resulted in live births 41.6%. Of these live births, 51.8% were singletons, 42.0% were twins and 6.3% were triplets or more.  Note: Total does not equal 100% due to rounding.
• 5 or more embryos transferred: Percentage of transfers that resulted in live births 35.2%. Of these live births, 47.4% were singletons, 47.4% were twins and 5.3% were triplets or more. Note: Total does not equal 100% due to rounding.

Figure 35 is a pie chart representing the day of embryo transfer among ART cycles using fresh nondonor eggs or embryos, 2007. Note: Day of embryo transfer is defined as the number of days following egg retrieval. Cycles using GIFT or ZIFT are excluded. Missing or implausible values for day of embryo transfer (i.e., 0 or >6) are not included in these statistics. Total does not equal 100% due to rounding.

• Day 1, 0.1%
• Day 2, 4.5%
• Day 3, 59.3%
• Day 4, 2.9%
• Day 5, 31.2%
• Day 6, 1.9%

Figure 36 is a bar graph representing percentages of day 3 and day 5 embryo transfers using fresh nondonor eggs or embryos that resulted in live births, by woman’s age, 2007. Note: Cycles using GIFT or ZIFT are excluded. This comparison is limited to transfers on day 3 and day 5. Embryo transfers performed on days 1, 2, 4, and 6 are not included because each of these accounted for a small proportion of procedures.

Note: Cycles using GIFT or ZIFT are excluded.  This comparison is limited to transfers on day 3 and day 5.  Embryo transfers performed on days 1, 2, 4, and 6 are not included because each of these accounted for a small proportion of procedures.

For this reason, a small percentage of twins resulted from a single embryo transfer and a small percentage of triplets resulted when two embryos were transferred.

• 1 embryo transferred: Percentage of transfers that resulted in live births 52.1%. Of these live births, 97.3% were singletons, 2.6% were twins and 0.2 were triplets or more. Note: Total does not equal 100% due to rounding.
