Blastocyst is a day 5 embryo and under a microscope, looks different from a day three embryo. A day-3 embryo comprises of eight cells. In the middle of the blastocyst, there is a fluid-filled cavity called the blastocoel. There is another area where you can see a dense collection of cell, which becomes the fetus. Just close to the central cavity is an assortment of cells which will develop into the placenta. Transferring blastocyst is easier for implantation than a day-3 embryo as it is a better-developed embryo and it is more matching and natural process of Implantation.

2 of 5
A blastocyst is a human embryo, which is five to seven days old. Earlier, day-3 embryos were always transferred during IVF treatment to the womb. According to the latest research, it has been found that transferring blastocysts increases the chances of a successful pregnancy, as they are well-developed embryos. The embryo that survives for more than five days is more viable for the implantation process. The future of younger embryos is harder to assess. You must consult with your fertility doctor regarding the stage of the embryo for the transfer because each patient is different.

After IVF transfer, the blastocyst can split, resulting in twins. In this process, identical twins are quite common. Blastocyst transfer can also result in quadruplets, which is quite rare. It is recommended to transfer one good quality blastocyst of during the IVF treatment. If two blastocysts are transferred, there are high chances of twins. Before going to the clinic, look at your options and decide if you want to transfer one or two blastocysts.

Although transferring blastocysts make things easier for implantation, many IFV patients do not use blastocysts due to certain reasons. The medical history and the age of a woman play a vital role in determining if blastocysts can be transferred. The quality and number of embryos created in your IVF cycle are also important since the embryo must reach the blastocyst stage to be transferred to the uterus. Only after analyzing all the conditions can your consultant tell you if it is safe to transfer a blastocyst. Get your medical history checked by your consultant before IVF treatment.
