Our Success Rates

The fertility team at Harvard Vanguard Medical Associates is proud of both our success rates and the low rate of multiple pregnancies as a result of IVF treatment in our hands. We believe we have been able to achieve these excellent success rates as a result of our personal, individualized approach to care.

Below please find our pregnancy outcomes shown by age group for the years 2009, 2010, and 2011. These represent outcomes of IVF procedures performed for Harvard Vanguard patients.*

To learn more about IVF or how data are reported nationally, please visit the Society for Assisted Reproductive Technology (SART) database. If you would like more information as to what each line of these outcomes data represent, please see the definitions below. For information on success rates of patients over the age of 42, please discuss with your physician.

Definitions

  • Number of cycles: Number of cycles initiated in each age group (based on the female partner's age)
  • % of cycles resulting in pregnancies: This is the percentage of fresh, non-donor cycles where a cycle was initiated and the outcome was an intrauterine pregnancy (documented by ultrasound). This does not always result in a live birth. Some of these pregnancies result in a miscarriage, ectopic pregnancy, or a voluntary termination of a pregnancy.
  • % of cycles resulting in live births: This is the percentage of fresh, non-donor cycles where at least 1 live birth occurred, shown as a percentage for each age group per cycle initiated. A live birth is counted when at least one fetus was born live; generally, when a birth certificate is filed.
  • % of transfers resulting in pregnancies: This is the percentage of fresh, non-donor cycles where a transfer occurred (some cycles are cancelled prior to embryo transfer) and where a pregnancy occurred, as documented by ultrasound.
  • % of transfers resulting in live births: This is the percentage of fresh, non-donor cycles where a transfer occurred, resulting in at least one (1) live birth.
  • % of cycles with elective single embryo transfer: This is the percentage of fresh, non-donor cycles that reached transfer where there was more than one embryo available, but electively, only 1 embryo was transferred to minimize the risk of a multiple pregnancy.
  • Average number of embryos transferred: This is the average number of embryos transferred by age group per cycle and only for fresh, non-donor cycles.
  • % of live births with twins: This is the percentage of fresh, non-donor cycles by female age group where at least 1 live birth occurred and where the pregnancy result was twins.
  • % of live births with triplets or more: This is the percentage of fresh, non-donor cycles by female age group where at least 1 live birth occurred and where the pregnancy result was triplets or more.
