The development of test tubes in Thailand has matured and stabilized, and has been progressing, test tubes have now developed to three generations, and it is the consensus of many people to choose a good time or not, so many infertility people have begun to give up the first and second generation test tubes. So what is a three-generation test tube? The following is a detailed analysis of the "Thai three generations of test tubes" by Hengjian Overseas.
Thai three-generation IVF, also known as preimplantation genetic diagnosis, referred to as PGD, refers to the method of taking the genetic material of the embryo before the IVF-ET embryo transfer, diagnosing whether there is abnormality, screening healthy embryo transfer, and preventing the transmission of genetic problems. Generally, 4 to 8 embryos that have been fertilized and cultured and developed are extracted with a fine needle and then examined for genetics or molecular genetics. DNA analysis for detection, one is polymerase chain reaction (PCR), to detect genetic problems; The other is fluorescence in situ hybridization (FISH), which detects chromosomal problems. Embryos with normal examination results will be placed in the body to complete the purpose of eugenics, which is three generations of test tubes.
For example, the eugenic principle of some genetic problems such as malnutrition and color blindness is the same as that of hemophilia. As long as this genetic trait is understood, the embryos bred in the test tube can be tested and healthy embryos selected for implantation, thus avoiding the birth of a child with genetic problems.
Therefore, the progress and achievements made by three generations of test tubes are unprecedented, from the perspective of biological genetics, it helps people to choose to have healthy babies, and provides opportunities for people with genetic problems to have healthy children.
At present, the world's test tubes first think of the United States, Thailand two, famous in Asia, the three generations of test tubes they use, the use of mature experience and high probability of success, up to more than half; In hospitals in the mainland, second-generation test tubes are commonly used, and regardless of experience, the probability of success is difficult to match in the United States and Thailand.
Therefore, in the mainland, Thai ivory tubes are favored by infertility families, with high probability of success, affordable prices, not far from China, and can also travel by the way, which has dealt with the problem of having babies for many infertility friends.
Through the above detailed introduction, I believe that everyone has an understanding of the three generations of test tubes, if you want to do test tubes, then you can choose your own suitable test tubes according to your own situation and economic conditions.
