Blastocyst Culture / Transfer

Embryos that are followed and developed in the laboratory for 5 days are called blastocysts. Embryo transfer performed on the 5th day is also called blastocyst transfer. So, why and to whom is this procedure done?

Why is Blastocyst Transfer Done?

Blastocyst stage embryos are obtained on the 5th or 6th day after fertilization in the laboratory environment. After this period, it is not possible to culture embryos in a laboratory environment. It needs to be transferred to the uterus. In 6-7 days after embryo transfer, it gets rid of its protective layer, the zona pellucida, and begins to cling to the uterine tissue.

Why is Blastocyst Transfer Preferred?

In all countries, legal restrictions have been imposed on the number of embryos transferred in order to be protected from the risks of multiple pregnancies. In our country, this limit is a maximum of 2 embryos. By giving 1 or 2 blastocysts in embryo transfer on the 5th day, both the risk of multiple pregnancies is reduced and the chance of pregnancy is increased. Embryos with chromosomal abnormalities are much less likely to reach the blastocyst stage than normal embryos. Thus, the probability of selecting chromosomally healthier embryos in 5 days is high. Therefore, higher implantation (attachment to the mother’s uterus) and pregnancy rates can be achieved with the 5th-day transfer.
