Can IVF achieve twins?
The development of IVF technology has made many infertile couples see the hope of fertility. However, some people are curious about whether IVF can achieve twins. Dragon and phoenix twins refer to a pair of opposite sex twins. The male is called dragon, and the female is called phoenix. This article will elaborate on the possibility of the realization of dragon and phoenix fetuses in IVF from the following four aspects.
Fundamentals
In vitro fertilization (IVF) is a method of assisting pregnancy in the process of in vitro fertilization and embryo culture. First, the woman needs to promote the development and maturation of eggs through ovulation guidance drugs or other technologies, and then obtain eggs from the woman's body. Then, the doctor will obtain the egg and the man's sperm for in vitro fertilization, so that the fertilized egg is formed. Finally, the doctor will cultivate the fertilized egg to a certain stage of development, and then transplant it back to the woman's uterus. The number of fertilized eggs and the choice of operation technology are needed to control the number of fertilized eggs for IVF to realize the dragon and chicken fetus.
First, in order to achieve the twins, we need to obtain a sufficient number of fertilized eggs. In general, in order to improve the success rate, doctors will cultivate multiple fertilized eggs at the same time, screen them during the embryo culture process, and select the embryos with normal development for transplantation. Multiple fertilized eggs with normal development can increase the chance of twins.
Second, the selection of appropriate embryo transfer technology is also the key to the realization of twins. At present, there are three common embryo transfer technologies to choose from: single embryo transfer, double embryo transfer and three embryo transfer. Single embryo transfer can minimize the risk of multiple pregnancy, but it also reduces the possibility of twins. Double embryo transfer can increase the chance of twins, but it also increases the risk of multiple pregnancy. Three embryo transfer can improve the chance of twins, but the risk of multiple pregnancy also increases.
Technical limitations
Although IVF technology can assist in pregnancy, it is not necessarily a success to achieve twins. First, the number and quality of the woman's eggs are important factors that restrict the success rate. If the woman's ovary function is abnormal, the number of eggs is small or the quality is poor, then it will be difficult to obtain sufficient number and quality of fertilized eggs.
Secondly, the selection of operation technology and the experience of doctors also play an important role in the realization of twins. IVF technology requires advanced operation technology and rich experience to ensure the normal development of fertilized eggs and the success of transplantation. If the operation technology is not skilled or the experience is not enough, it may lead to the loss of fertilized eggs or unsuccessful transplantation.
In addition, the internal genetic genes of fertilized eggs will also affect the development of embryos and the success rate of transplantation. Although IVF technology can assist in pregnancy, it cannot change the genetic characteristics of the fertilized egg itself. If the genetic genes of the fertilized eggs are not suitable for developing into twins, the chances of achieving twins will also be greatly reduced.
Actual cases and clinical practice
Although it is not easy for IVF to achieve twins, there have been some successful cases in clinical practice. For example, Changsha Central Hospital has successfully implemented the technology of test tube twins. This technology is realized by regulating hormone levels, increasing the number of transferable embryos, and optimizing embryo culture conditions. This successful case provides a certain reference for other infertile couples to achieve twins.
In addition, with the continuous progress of IVF technology, more and more hospitals and doctors are also actively studying and exploring the methods and technologies to realize the twins. They hope to improve the success rate of twins by constantly improving operation techniques, optimizing culture conditions, and screening fertilized eggs suitable for twins.
conclusion
To sum up, it is possible for IVF to achieve twins, but not all infertile couples can succeed. The realization of twins needs to master certain skills and experience, and is also affected by individual physical conditions and genetic factors. However, with the progress of technology and the accumulation of clinical practice, the hope of realizing the twins is gradually increasing. It is believed that in the near future, more and more infertile couples will be able to achieve their dream of having twins.
