Does PGS increase success of IVF?
Recent research has found that screening embryos with PGS and transferring only the ones that are chromosomally normal can increase IVF success rates by as much as 23 percent.
What percentage of PGS tested embryos come back normal?
Patients often hear “PGS-normal embryos have a 60 – 70% success rate.” But that is on a per-transfer basis. Meaning that if you begin a cycle, retrieve eggs, produce embryos, then do PGS testing, and at least one embryo comes back normal, 60 – 70% of the time it will lead to a live birth.
How accurate is PGS testing IVF?
PGS is a highly advanced technology and has an accuracy rate of 97%, but it is important to know that PGS has limitations, which you should discuss with your doctor or genetic counselor. That being said, of the result options, this is the one you want.
Are PGS tested embryos more likely to implant?
Benefits of PGT-A (or PGS) Genetic Testing. When women transfer PGT-A tested (and approved) embryos, those embryos are far more likely to implant and lead to a successful transfer.
Is PGT a testing worth it?
PGT-A may also be helpful when a patient has excess embryos they plan to store for future use. Since embryos with aneuploidy are more likely to result in a failed IVF cycle or miscarriage, PGT-A provides additional information about the reproductive potential of those embryos.
Why would a PGS tested embryo not implant?
The lining of the uterus is receptive to the embryo for only a brief time, called the Window of Implantation. It is possible that a perfectly normal embryo might not implant because the lining was not ready for it. In natural cycles, the window may be 4-5d wide, but in our treatments in can be only 12-48h long.

What abnormalities does PGS test for?
PGS is a preventative measure used to identify chromosomal abnormalities in the embryo, even if there’s no known evidence of a genetic abnormality in either parent. The procedure screens for chromosomal abnormalities, such as Down Syndrome (Trisomy 21), as well as abnormalities in chromosome position (translocations).
Should I transfer 1 or 2 embryos after PGS?
One is best – most of the time. Research still shows that transferring one embryo per cycle is the safest option. Transferring two increases the chance of a multiple pregnancy and associated complications. (Not by a huge margin, but the risk is still significant.)
