Blastocyst transfers
Blastocyst / Day 5 Transfer
Blastocysts are the embryos that have cultured further in the lab till day 5 after fertilization. These embryos on day 5 are called Blastocysts and have a higher chance of implantation (success) compared to earlier embryos. The biggest advantage is that it increases its chances by reducing the risk of multiples.
Embryos which are usually transferred on day 2 or 3 of the fertilization, have just about 4-10 cells. The blastocyst on other hand comprises 70-100 cells, possesses an inner cell mass (ICM), and an outer layer of cells surrounding the inner cell mass, and a fluid-filled cavity known as the blastocoele. An enzyme of the cells on the exterior erodes the outer lining and creates a site for implantation. (Thereby increased chances of success rate).
Zoi Fertility is one of the few clinics in India, where Blastocyst transfers, which is considered the foremost technique in IVF, are performed since 2014. This has indeed translated as a higher success rate.

Blastocyst Transfers as a Tool to Evaluate an IVF Lab
When embryos are cultured to grow from day 3 to day 5 blastocysts, this happens because of 2 factors.
a) The intrinsic health and potential of the embryo
b) the IVF lab quality standards.
There should be no lab that cannot form Blastocysts, but then most labs presently are not tuned to set up standards to create an environment for Embryo to grow into Blastocyst.
