IVF 3.0+
(The information is from the Stork Fertility Center)
IVF 3.0+ = Precise Embryo Choosing (PGS) + Precise Implantation (ERA)
The Third generation IVF Plus is built upon the core treatment - Personalized Precision IVF, with the addition of PGS (Preimplantation Genetic Screening) and ERA (Endometrial Receptivity Analysis).
According to the Stork Fertility Center's statistics in 2017~2018, the pregnancy rate of transferring one chromosome-normal blastocyst at or above BB grade can be 80%. The chances of having twins were less than 1% and the miscarriage rate was less than 5%.
The remaining 20% can be addressed through additional methods such as EMMA and ALICE, which are screening tests that evaluate bacteria in the uterine cavity. Other approaches include reproductive autoimmune screening and blood clotting tests.
The grade of blastocyst stage embryo
During the blastocyst stage, embryonic cells differentiate into two cell types:
- Inner Cell Mass which eventually develops into the baby.
- Outer Cell Mass (trophectoderm) which eventually forms into the placenta.
A blastocyst is graded on three elements, for example: 4AB
4→ Indicates the expansion and hatching status, numbered 1-6 (6 being the most expanded)
A→ Indicates the Inner Cell Mass quality, ranked A-C (A being the best)
B→ Indicates the Outer Cell Mass quality, ranked A-C (A being the best)
