In IVF, embryos are implanted into the uterus of the female, two to three days after fertilization. However, Blastocyst Culture allows us to grow the embryos up to five days in the laboratory, inside a Tri Gas Incubator till it reaches the blastocyst stage, provided we have enough number of embryos. After which the doctor can select the most suitable embryos for implantation. This not only lessens the number of embryos transferred into the uterus, but the chances of conceiving are also increased. Blastocyst Culture also significantly decreases the risk of high order multiple pregnancies.
