When discussing reproductive choices, twins often become a main point of discussion. For many families, conceiving twins is a dream, but the challenges that come with it cannot be overlooked. This article will introduce the classification and formation mechanisms of twins, as well as the situation related to in vitro fertilization (IVF) technology.
Firstly, let's understand the two types of twins: dizygotic twins and monozygotic twins. Dizygotic twins refer to when a woman simultaneously releases two eggs, each of which is fertilized and implanted in different locations of the endometrium, ultimately developing into two babies. Each baby has an independent placenta and amniotic sac, with no direct connection between them. On the other hand, monozygotic twins are formed when a fertilized egg splits into two embryos. In monozygotic twins, the gender and blood type of the two babies may be the same, and they often share a high degree of facial resemblance.
Having understood the classification of twins, let's delve into the situation related to IVF technology. Through IVF technology, especially dizygotic twins are more common. In such cases, most institutions consider transferring an additional embryo during embryo implantation to increase the success rate. However, IVF clinics in the USA mostly utilize third-generation IVF-PGT technology, conducting PGS/PGD screening before embryo transfer, and only consider transferring twins upon special request. Since the birth of twins increases the risks for both pregnant women and babies, transferring twins is not common. Dr. Nathan Zhang highlighted the advantages of the complete and protective reproductive industry chain in the USA, emphasizing the protection of newborns and the perfection of the medical system. Additionally, as a member of the American Society for Reproductive Medicine and the International Medical Tourism Association, IVF USA initiates ovarian stimulation and egg retrieval domestically, requiring only a 5-7 day stay in the USA. They provide strict legal protection (parental rights, international, medical, insurance, etc.) and offer every customer high-quality medical service and personalized treatment plans.
In conclusion, twins are a reproductive choice full of joy and challenges. By understanding the classification and formation mechanisms of twins, as well as the situation related to IVF technology, you can gain a more comprehensive understanding of this topic.
