Effect of HCG value of test tube baby on embryonic development
IVF refers to the process of combining female eggs with male sperm in the laboratory, cultivating them into embryos, and then implanting them into female uterus through IVF technology. In this process, HCG (human chorionic gonadotropin) is a very important indicator, which plays a key role in embryonic development.
1. Definition and generation of HCG
HCG is a hormone obtained from the embryo after female pregnancy. It was first synthesized by chorionic cells and later produced by embryos and trophoblasts. HCG is mainly used to maintain the function of corpus luteum and promote the production of progesterone in corpus luteum, thus providing support for embryo implantation.
In the process of IVF, HCG production is usually achieved through induction of embryo culture. After successful fertilization, the embryo will continue to develop, producing HCG in this process. The changes of HCG levels can be used to monitor the development of embryos.
2. Relationship between HCG and embryonic development
HCG plays an important role in embryo development. After embryo implantation, it can promote blood flow and nutrient supply of endometrium, thus providing guarantee for embryo development. In addition, HCG can also promote the maturation of embryos and ensure their good adaptability in the uterus.
The process of embryonic development can be understood by monitoring the level of HCG. In the process of IVF, doctors usually use blood tests to measure the level of HCG to assess the development of the embryo. If the HCG level continues to rise, it can indicate that the embryo is developing well; However, if the HCG level drops or fluctuates greatly, it may mean that there is a problem in the development of embryos.
3. HCG value and embryonic development stage
During embryonic development, the level of HCG will also change. In the early stage after fertilization, the level of HCG will continue to rise, and it is generally of value from 10 days after fertilization. When the HCG level reaches a certain value, it can be monitored by fluorescence method, radioimmunoassay and other methods.
The level of HCG varies at different stages of embryonic development. After embryo transfer, the level of HCG will gradually rise, and the peak usually occurs in the 8-10 days after embryo transfer. If the HCG level decreases or does not increase at this stage, it may indicate that the embryo has not been successfully implanted.
4. Evaluation of HCG value and disease screening
In addition to monitoring embryonic development, HCG levels can also be used to assess the risk of some diseases. For example, if women of childbearing age have abnormal HCG levels, it may be a warning signal for ectopic pregnancy, abortion, fetal chromosome abnormalities and other problems.
In addition, the level of HCG can also be used to assess the risk of twin or multiple births. Generally speaking, the HCG level of multiple pregnancy is high, which is because the number of placentas produced during multiple pregnancy is increased, thus more HCG is secreted. Therefore, the number of fetuses can be predicted by monitoring the level of HCG in early pregnancy.
Summary
HCG is an important index in the process of IVF embryo development, which plays a key role in embryo implantation and development. By monitoring the level of HCG, we can understand the development of embryos and find possible problems in time. In addition, the level of HCG can also be used to assess the risk of some diseases. Therefore, in the process of IVF, the monitoring of HCG is of great significance, which can provide doctors and patients with valuable information.
