Did you know that the embryo has a 95 to 100 per cent chance of survival with the ART or assisted reproduction technology of vitrification? FBT or Frozen blastocyst transfer is usually done after the follicular aspiration's 5 th day. In this procedure, the transfer of single or multiple embryos takes place. These embryos are in an advanced development stage known as the blastocyst stage. The 5 th -day frozen blastocyst transfer success rate is considerably higher than the 3 rd -day. During embryo development's first 3 days, the division leads to the formation of separate cells. These are known as cleavage embryos. From day 3 onwards, the formation of blastocyst takes place. Structurally, a cleavage embryo is less complex than a blastocyst embryo. There are more than 100 cells that are formed during the blastocyst development stage. These cells are differentiated into two types, namely inner cell mass and trophoblast. Let us further discuss frozen blastocyst transfer. ...
