|Age of female partner (using own eggs)||<35 years old||35-37 years old||38-40 years old||41-42 years old||DONOR EGG IVF Recipients|
|Fresh embryos*:Live birth or ongoing pregnancy per transfer||
|Frozen embryos*: Live birth or ongoing pregnancy per transfer||58%
Live birth or ongoing pregnancy per transfer.
*Fresh and frozen embryos that did not utilize PGS.
**PGS = Preimplantation genetic screening.
Frozen-Thawed Embryo Transfer from Donated embryos = 50% (14/28)
All 2015 data are live births. 2016 data are a mixture of live births and ongoing clinical pregnancies (fetal heart beat seen). Similar to many clinics nationwide, 2015-2016 were transition years where we starting making a fundamental change in IVF by moving away from fresh transfers and towards more frozen-thawed transfers. We also have increased our utilization of PGS. The Society for Assisted Reproductive Technology (SART) now reports cycle outcomes as “Primary” or “Subsequent”. Primary outcome is from the first transfer following a retrieval and could be fresh or frozen. Subsequent are any additional transfers following the first, and are always frozen.
See the SART website for complete success rates data. A comparison of clinic success rates may not be meaningful because patient medical characteristics, treatment approaches and entrance criteria for ART may vary from clinic to clinic.
