In This technique, the embryos are cultured in the laboratory incubator for 5 to 6 days, instead of implanting in 2 or 3 days.
This process allows us to identify the best and healthy embryo to be transferred. It is basically a process of selecting the best embryo.
When younger women go for IVF, blastocyst transfer is considered to increase the success rate of IVF. We also consider Blastocyst good options in case of multiple IVF failures
Blastocyst embryos are day 5 Embryos, fully fertilized. Transfer of day 5 embryos, is called blastocyst transfer. The risks involved in it are only that not all embryos grow into the blastocysts in the laboratory. So this is decided on day 3 whether to go for blastocyst or not if we have a surplus of embryos than we can take a chance but if the number of embryos is less than no blastocyst transfer is done. The embryos are transferred on day2/ day3. We are very much inclined to do blastocyst transfer, If we have a sufficient number of embryos on day 3, then the embryologist and the specialist with the consent of the couple together take the decision for blastocyst transfer and do the best transfer for you. Even if we have a sufficient number of embryos on day 3 we still freeze two on day 3 and take the rest of the embryos to day 5 in case blastocyst do not form.
