What is the success rate of blastocyst transfer in vitro?

With the continuous improvement of medical technology, the technology of assisted reproduction such as IVF has also been continuously developed, and many patients have successfully conceived. However, this method cannot completely guarantee success. It will only increase the chance of conception while reducing the risk to the human body. There are many reasons for female infertility. So what is the success rate of blastocyst transfer in IVF?

First, what is the success rate of blastocyst transfer in vitro? Blastocyst is the final stage of embryo culture in vitro, and it is usually formed on the 5th to 7th day after the egg is fertilized. Under natural conditions, human embryos implant into the mother in the form of blastocysts. Therefore, it is not difficult to understand that blastocyst transfer can achieve a higher embryo implantation rate.

Second, for embryos and blastocysts with the same vitality, the transplantation success rate of blastocysts is higher than that of embryos. Because the blastocyst is cultured for two days longer than the embryo, the number of cells increases from single digits to triple digits, and there is also a huge change in morphology, from a spherical shape to one with a small tail. Not only is the vitality enhanced, but the implantation area after implantation in the uterus also becomes larger. These are all important foundations for the survival of the blastocyst. Therefore, it is obvious that the survival rate of blastocyst transplantation will be much higher than that of embryo transplantation.

Third, most of the transplants in China are embryo transplants, with a success rate generally between 20-30%. In Thailand, blastocyst transplants are performed, with a success rate generally around 80%. The success rate can be higher in good clinics. At the same time, Thai test tube babies have an important operation before transplanting the blastocyst, which is PGD screening of the blastocyst. This technology can directly eliminate blastocysts with low vitality or recessive genetic diseases, and rate the cell uniformity and activity of the blastocyst. Finally, the healthiest blastocyst is selected for transplantation, which can greatly improve and guarantee the success rate.

What is the success rate of test tube transfer of blastocysts? The above content introduces the advantages of this method: stimulating the developmental potential of the embryo: whether the embryo can develop into a blastocyst is related to its own genes. When the embryo has no developmental potential or carries abnormal chromosomes and genes, it may be naturally eliminated due to its own developmental abnormalities during the extended culture process. Only the best quality embryos can develop into blastocysts. Embryo development is more synchronized with the endometrium: Blastocyst stage transfer can provide a natural environment that is closer to reproductive physiology and has a higher implantation ability.
