Can IVF achieve multiple pregnancy of twins?
With the development of IVF technology, many couples have realized their dream of childbearing. However, many people have doubts about whether IVF can realize the multiple pregnancy of twins. This article will elaborate on this issue from many aspects.
1. Concept and process of IVF
IVF is a kind of assisted reproductive technology, which is usually used to help couples who cannot conceive naturally to achieve fertility. This technology usually includes two main steps: in vitro fertilization (IVF) and embryo transfer. First, doctors will take mature eggs from women's bodies and combine them with male sperm in the laboratory to develop them into embryos in a petri dish. Then, the doctor will select a healthier embryo and implant it into the female uterus to promote the occurrence of pregnancy.
Although IVF technology can help couples get pregnant, it cannot guarantee the occurrence of multiple births. In the process of embryo transfer, only one or a few embryos are usually selected for implantation to avoid the potential risks of multiple pregnancy to the health of the mother and fetus.
2. Possibility of multiple embryo implantation and multiple pregnancy
Although the principle of IVF technology is to control the number of multiple fetuses, sometimes multiple embryos are implanted in one cycle to increase the success rate of pregnancy. The purpose of this is to improve the success rate while hoping for a successful pregnancy, but it also increases the risk of multiple births. According to international statistics, the probability of multiple pregnancy is about 0.5% to 3%. In other words, multiple pregnancies do not necessarily occur during IVF.
Although multiple pregnancy may bring some problems, such as premature delivery and low birth weight, and in some cases may even lead to abnormal child development, the risk of multiple pregnancy is gradually reducing with the progress of technology and the fine operation of doctors.
3. Concept and incidence of twins
Dragon and Phoenix twins refer to a pair of male and female twins, called "Dragon twins" and "Phoenix twins" respectively. They develop in the same gestational sac and belong to a relatively rare type of multiple births. According to the statistical data, the occurrence probability of twins is about one in every 300 pairs of twins. The incidence of this twin type is very low. Not all IVF babies can successfully conceive twins.
4. Key factors to realize dragon and chicken embryo
In order to achieve the pregnancy of dragon and phoenix fetuses, there are also some key factors that need to be considered in addition to accidental factors. First of all, women's age has a great impact on the occurrence of twins. Young women are more likely to get pregnant. Secondly, whether there are twins born in the family history may also be related to the individual's genetic genes.
In addition, some studies have shown that carrying out gene screening or embryo screening of new technologies before embryo transfer and selecting embryos carrying the genes of dragon and phoenix embryos for implantation may increase the success rate of dragon and phoenix embryos. This is based on the research of embryonic genetics and the development of science and technology.
Summary
To sum up, IVF may not be able to achieve multiple pregnancy of twins. In vitro fertilization (IVF) and embryo transfer (ET) are two main steps in IVF technology, and the probability of multiple births during ET is low. To realize the pregnancy of dragon and phoenix fetus, multiple factors such as female age, genetic factors and embryo screening need to be considered. The development of IVF technology is still in progress, which has more possibilities for achieving the pregnancy of twins.
