How are IVF multiple births formed?
In vitro fertilization (IVF) is a process in which the fertilized eggs are cultivated to a certain stage, and then one or more fertilized eggs are implanted into the mother's uterus to achieve pregnancy and delivery. Multiple pregnancy is common in IVF technology. The following will elaborate on how IVF multiple births are formed from embryo segmentation, multiple implantation of fertilized eggs, implantation and epistasis, etc.
Embryo segmentation
Embryo segmentation is a kind of operation carried out in the in vitro culture stage, which forms multiple embryos by dividing the normally developed embryos into multiple cell clusters. There are two main ways of this division: natural division and artificial division.
Natural division means that in the process of early embryonic development, the embryo divides itself to form two or more cell clusters, and each cell cluster has the potential to develop into an embryo. This natural division is common in the first three days of early embryonic development.
Artificial division refers to the division of early embryos by using specific instruments and technologies in the process of in vitro culture. This segmentation can divide a fertilized egg into two independent cell clusters, and each cell cluster can develop into an embryo. Artificial cleavage can increase the chance of multiple births in IVF.
Embryo segmentation increases the chance of multiple embryo formation, and thus increases the probability of multiple births of IVF.
Multiple implantation of fertilized eggs
Multiple implantation of fertilized eggs is a common IVF technology, which increases the chance of pregnancy by implanting multiple fertilized eggs into the mother's uterus. This method is usually used when the quality of fertilized eggs is poor or the patient is older.
Multiple implantation of fertilized eggs can be divided into two ways: simultaneous multiple implantation and multiple implantation at different stages.
Simultaneous multiple implantation refers to the simultaneous implantation of multiple fertilized eggs into the mother's uterus. This method can increase the total number of test tube babies with multiple pregnancies, but it also increases the risk of multiple pregnancies.
Multiple implantation at different stages refers to multiple implantation of fertilized eggs in multiple cycles. Multiple implantation can increase the probability of multiple pregnancies in IVF and reduce the risk of multiple pregnancies.
Implantation superior position
Implantation epistasis refers to the process in which the fertilized egg is implanted into the mother's uterus. In IVF technology, after a period of in vitro culture, embryos are implanted into the mother's uterus to achieve the purpose of pregnancy and delivery.
The implantation position is closely related to the quality of embryo and the intrauterine environment. Good intrauterine environment and high-quality embryos can improve the probability of multiple births in IVF.
Summary
The formation of IVF multiple fetuses is mainly achieved through embryo segmentation, multiple implantation of fertilized eggs, and implantation and epistasis. Embryo segmentation can increase the chance of multiple embryo formation, multiple implantation of fertilized eggs can increase the probability of pregnancy, and implantation is the key step to achieve IVF multiple births. However, it should be noted that the formation of IVF multiple pregnancies is also accompanied by the risk of multiple pregnancies. Therefore, appropriate methods and quantities should be carefully selected when carrying out IVF technology.
