In vitro baby technology upgrading: the difference between the first generation and the second generation
IVF technology is an assisted reproductive technology that helps couples who cannot conceive naturally to have a smooth birth by transplanting the fertilized eggs into the uterine cavity. With the continuous progress of science and technology, IVF technology is also constantly upgrading. This article will elaborate the differences between the first generation and the second generation of IVF technology from four aspects.
1、 Improvement of embryo quality
The first generation IVF technology has relatively poor conditions for embryo culture, and the quality of embryo development is uneven. However, with the development of technology, the second generation of IVF technology makes use of more advanced embryo culture systems, providing a more stable and superior environment for embryos. This makes the embryo develop more healthily and increases the probability of successful pregnancy of IVF.
In addition, the second generation of IVF technology uses PGS (embryonic gene screening) technology, which can conduct genetic screening on embryos and screen out embryos with gene defects. This allows couples to choose healthy embryos for transplantation, reduces the risk of fetal malformation and abortion caused by chromosome abnormalities, and increases the probability of successful pregnancy.
In addition, it is worth mentioning that domestic medical institutions such as Peking Union Medical College Hospital and Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine have applied the second-generation IVF technology and achieved good clinical results.
2、 Implant selection
In the first generation IVF technology, only one fertilized egg is usually implanted when the embryo is implanted, so the success rate is relatively low. However, the second generation of IVF technology introduced the single embryo transfer technology, that is, only one high-quality embryo was implanted. This can reduce the risk of multiple pregnancy, reduce the complications of pregnant women and fetuses, and improve the success rate of IVF.
In addition, the second generation IVF technology also introduced the screening of folate receptor affinity enzyme gene, which can determine whether the activity of receptor affinity enzyme is low. Through screening, we can prevent the birth of abnormal fetuses caused by abnormal folate metabolism.
It is worth mentioning that authoritative medical institutions such as Boston Children's Hospital in the United States have accumulated rich experience in the research of the second-generation IVF technology and made significant progress.
3、 Reduction of pregnancy complications
In the first generation of IVF technology, due to the relatively high rate of multiple pregnancy, the risks borne by pregnant women and fetuses also increase accordingly. However, the introduction of single embryo transfer into the second-generation IVF technology has significantly reduced the proportion of multiple pregnancies and reduced the risk of maternal and fetal complications.
In addition, by means of embryo quality screening, the second-generation IVF technology has reduced the risk of fetal malformation and abortion caused by chromosome abnormalities, reduced the probability of embryo implantation failure, and shortened the time for IVF treatment.
IVF Center in Melbourne, Australia and other internationally renowned medical institutions have made breakthrough achievements in the research of the second generation IVF technology as early as, providing safer and more effective IVF technology.
4、 Improvement of fertility success rate
The success rate of the first generation IVF technology is relatively low, and many couples need to try many times to get pregnant successfully. However, the continuous progress of the second generation IVF technology has significantly improved the fertility success rate.
The second generation of IVF technology makes couples more likely to successfully conceive and give birth by improving embryo quality, reducing multiple pregnancies, reducing the risk of pregnancy complications and other means. Around the world, many IVF technology research centers, such as Cambridge University in the UK and the Reproductive Medical Research Foundation in New York in the United States, have carried out relevant research and achieved remarkable results.
Summary
By comparing the first generation and the second generation of IVF technology, we can clearly see the upgrading and improvement of the second generation of IVF technology. The second generation of IVF technology has made important breakthroughs in the improvement of embryo quality, selection of implants, reduction of pregnancy complications and improvement of fertility success rate. These advances have made IVF technology a safer, more effective and more reliable reproductive assistance technology, bringing more hope to couples who cannot conceive naturally.
