IS THE DIAGNOSTIC BIOPSY HARMFUL FOR THE FURTHER DEVELOPMENT OF THE EMBRYO?

When it is performed on the stage when it consists of 7 or more cells (blastomeres) under suitable technical conditions, and by experienced staff, biopsy procedures do not give harm to the further development of the embryo.

HOW IS IT DETERMINED ON WHICH DAY THE EMBRYO WILL BE TRANSFERRED?

The transfer day of the embryo is determined according to the factors like age of the woman, the reason for IVF treatment, the results of the previous attempts, developmental characteristics of the embryos, whether or not pre-implantation diagnostic procedures will be performed, number of the developing embryos, and daily development rate of the embryo. Transfer can be performed on 3rd, 4th, 5th, and 6th days, 3rd day being the earliest and 6th day the latest.

HOW IS THE DECISION FOR CULTURING THE EMBRYOS TILL THE BLASTOCYST STAGE CAN BE MADE, AND WHAT ARE THE ADVANTAGES OF IT?

It is possible to provide for the growth of the embryo after the 3rd day, according to the factors like the number of the oocytes collected, their qualities, characteristics of the fertilized oocytes (zygotes), and the daily development and cleavage rate of the embryos. The stage that the embryo reaches the uterus is the blastocyst stage. The internal wall of the uterus accepts the embryo more easily, as the compliance between the embryo and the internal part of the uterus is the highest in this stage. This is why the transfer of embryos of blastocyst stage, that is, embryos of 5th or 6th days are more advantageous for improving the ability of the embryos to hold on to the uterus wall, as well as avoiding the risk of multiple pregnancies by placing fewer embryos inside the uterus.
