The fertilized oocyte starts its cleavage in the test tube the chromosomes of the parents conjugated successfully, this is now the beginning of a new life. the chromosomes of the parents conjugated successfully, this is now the beginning of a new life. The fast motion video was shot by cameras in the incubator. They show what happened in the first five days under a few seconds. The test tube baby developing in front of the camera has been already born healthily since then. The test tube baby developing in front of the camera has been already born healthily since then. 8 out of 10 fertilized oocytes cleave in average, while two will not. 8 out of 10 fertilized oocytes cleave in average, while two will not. The cleavage will definitely not start where the oocyte or the sperm contained very erroneous genetical information. where the oocyte or the sperm contained very erroneous genetical information. What we can see here corresponds with the status of the 20th hour after conception. What we can see here corresponds with the status of the 20th hour after conception. This is the oocyte itself, and we can classify it as conceived if we can see the two so called pronuclei. This is the oocyte itself, and we can classify it as conceived if we can see the two so called pronuclei. This is the oocyte itself, and we can classify it as conceived if we can see the two so called pronuclei. All the embryos are examined under the microscope exactly 20 hours after the implantation. All the embryos are examined under the microscope exactly 20 hours after the implantation. This is an exceptionally important examination, as at this stage, This is an exceptionally important examination, as at this stage, the erroneous embryo development can be clearly seen. All the embryos must be examined as the incorrectly fertilized ova can be sorted out here. All the embryos must be examined as the incorrectly fertilized ova can be sorted out here. It can happen that there are three pronuclei instead of two which means that the ovum is defective, It can happen that there are three pronuclei instead of two which means that the ovum is defective, It can happen that there are three pronuclei instead of two which means that the ovum is defective, and it has a wrong set of chromosomes which would not be visible later during cleavage. and it has a wrong set of chromosomes which would not be visible later during cleavage. and it has a wrong set of chromosomes which would not be visible later during cleavage. and it has a wrong set of chromosomes which would not be visible later during cleavage. and it has a wrong set of chromosomes which would not be visible later during cleavage. The first crucial cleavage happens about 24 hours after the conception. The first crucial cleavage happens about 24 hours after the conception. In a properly developing embryo, two cells can be seen after the first day In a properly developing embryo, two cells can be seen after the first day four on the day after and eight on the next day More and more cells are created which become smaller and smaller, at this time inside the wall of the oocyte. More and more cells are created which become smaller and smaller, at this time inside the wall of the oocyte. By the end of the fifth day, the embryo consists of hundreds of cells, reaching the blastocyst stage. By the end of the fifth day, the embryo consists of hundreds of cells, reaching the blastocyst stage. It consists of tiny little cells, which are now uncountable. It consists of tiny little cells, which are now uncountable. In the middle we can see a hole inside, this is the so called blastocyst, In the middle we can see a hole inside, this is the so called blastocyst, this is how a nice embryo should look like on the fifth day. this is how a nice embryo should look like on the fifth day. At this development stage – as we can see it also on the video At this development stage – as we can see it also on the video – the shell that surrounds the embryo cracks and through the crack, the embryo that consists of hundreds of cells is squeezed out. the embryo that consists of hundreds of cells is squeezed out. The doctors find this the most suitable stage for implantation. As seen on the illustration, the embryo is injected directly on the endometrium As seen on the illustration, the embryo is injected directly on the endometrium where it implants quickly and easily. Even by the implantation of a single five day old embryo can give 50 percent probability for pregnancy. Even by the implantation of a single five day old embryo can give 50 percent probability for pregnancy. In the next part you can see how the five day old embryo is implanted in the uterus. In the next part you can see how the five day old embryo is implanted in the uterus.
