Blastocyst transfer

The proper development of the embryo in the body of a women or in laboratory (in vitro) conditions, implies certain dynamics of the division of the fertilized egg, in which the third day after fertilization we usually get an eight-cell embryo, which by further cultivation progresses to blastocyst stage, on the fifth day after fertilization. Blastocyst is the stage in development of embryos that occurs the 5th or 6th day, which generally indicates a greater chance of achieving pregnancy. Modern laboratory conditions, high standards, trained staff and the use of the most modern and highest quality media in our clinic, allow unrestricted cultivation of almost all embryos up to blastocyst stage. Not all embryos come to this stage, since the embryos with chromosomal abnormalities often stop development at an early stage. Blastocyst cultivation is used as a method of selecting the best embryo with the highest potential for pregnancy, and offers the option of returning even the small number of embryos and achieving pregnancy. Blastocyst transfer is performed on the fifth day after aspiration of of egg cells, and there are indications that this term carries a better receptivity of the uterus, because imitates the natural cycle (even in spontaneous conception, the embryo reaches the uterus only on the fifth day after ovulation, in the stage blastocyst).
