Blastocyst culture(day 5 embryo)
Blastocyst culture refers to growing the embryos in the laboratory for two more days at which point they are referred to as blastocyst embryos. Blastocyst transfer simply means that the blastocyst embryos are transferred to the women uterus on day 5 in exactly the same way that day 3 embryos are., This process ensures the high success rate.
If we have additional blastocysts, they can be frozen for future use. We generally suggest our patients to go for blastocyst culture if they had produced good quality embryos in their previous IVF cycle but had failed implantation due to different window of implantation.
