What are the different categories SART Reports?
Cycle – this means the start of medications with the intention of proceeding with IVF.
Retrieval – the removal of eggs from the ovaries.
Transfer – the placement of 1 or more embryos back into the uterus.
Single Embryo Transfer – the placement of just one embryo back to the uterus. Shady Grove Fertility refers to this as eSET or Elective Single Embryo Transfer.
Pregnancy – achieved when both blood testing and ultrasound show a pregnancy.
Live Birth – just what it sounds like, when a patient delivers a baby. This number will always be lower than the pregnancy rate due to the occurrence of miscarriage.
Implantation Rate – the chance that any one embryo will implant into the uterine lining and result in a pregnancy or a live birth.
Cancellation – An IVF cycle may need to be cancelled prior to completion. This could be due to insufficient or no eggs developing, no eggs fertilizing, or no embryos of sufficient quality to return to the uterus.
Is it Possible to Compare Fertility Centers Success Rates?
It’s natural for patients trying to decide between fertility centers to want to compare success rates between centers, but SART says these comparisons are not meaningful. SART states that comparing individual fertility center success rates is unreliable because factors, such as patient selection, patient medical characteristics, treatment approaches and program policies that can influence the statistics, vary from center to center. The clearest and most beneficial way to evaluate a center’s success is by comparing their individual success rates to the national SART averages.
What is the difference between Pregnancy Rate and Live Birth Rate?
A pregnancy is determined when both a blood test and ultrasound confirm a baby. The live birth rate is defined when a patient delivers a child (or children). Because some pregnancies end in a miscarriage, the percentage of cycles resulting in pregnancies is higher than the percentage of cycles resulting in live births.
What are delivery rates?
For this answer, patients would look at Live Births per Cycle, which may vary by age. While live birth rates slowly decline as the patient’s age increases, the patient’s cumulative chance of a birth increase with treatment cycles.
