Differences between test tube baby twins and natural twins
In vitro baby twins, dragon and phoenix twins and natural twins are twins formed in two different ways, and they are different in many aspects. The differences between the two will be described in detail in the following four aspects: genetic characteristics, pregnancy mode, birth probability and medical conditions.
Genetic characteristics
In vitro twins are usually twins formed by assisted reproductive technology (such as in vitro fertilization embryo transfer). In this case, parents can select embryos for transplantation through manual selection, thus making the genetic characteristics of dragon and phoenix fetuses more diverse. While natural twins are formed under natural conditions, their genetic characteristics are completely determined by their parents, and they cannot be selected during the whole pregnancy. Therefore, the genetic characteristics of test tube baby twins are more diverse.
Pregnancy mode
The pregnancy of test tube baby dragon and phoenix fetus is achieved through artificial assisted reproduction technology. Usually, the fertilized eggs are cultured to a certain stage in the laboratory and then transferred to the mother's uterus. This method can accurately control the time of pregnancy and the probability of pregnancy, and improve the success rate, but there are also certain risks and side effects. The pregnancy of natural twins is completely spontaneous, without external intervention. Therefore, the pregnancy mode of test tube twins is more special and limited by technology, while the pregnancy mode of natural twins is more consistent with the natural law.
Birth probability
Because IVF is formed by artificial selection, it has a high birth probability. This is because in the process of IVF, doctors can choose to screen and culture the fertilized eggs and select high-quality embryos for transplantation, thus improving the success rate of embryo implantation and development. The birth probability of natural twins is relatively low, because in natural circumstances, the implantation and development of fertilized eggs are completely determined by natural laws, and there is no opportunity for external intervention.
Medical conditions
The formation of IVF depends on assisted reproductive technology, which requires corresponding medical conditions and technical support. At present, some well-known hospitals in the world, such as Johns Hopkins Hospital in the United States and Imperial College London School of Medicine in the United Kingdom, are leading in assisted reproductive technology. The formation of natural twins does not require special medical conditions, but only two pregnant eggs are implanted at the same time. Therefore, the formation of IVF depends on medical conditions to a certain extent, while natural twins are not restricted by medical conditions.
To sum up, there are significant differences between test tube twins and natural twins in genetic characteristics, pregnancy mode, birth probability and medical conditions. The genetic characteristics of test tube babies with dragon and phoenix fetuses are more diverse, the pregnancy mode is more special, the birth probability is higher, and the formation requires higher medical conditions. However, the genetic characteristics of natural twins are completely determined by their parents. The pregnancy mode conforms to the natural law, the birth probability is low, and is not limited by medical conditions. These differences have important reference significance for family choice and medical decision-making.
