What is the relationship between HCG value of IVF and pregnancy results?
IVF refers to the embryos cultivated in the process of in vitro fertilization through assisted reproductive technology, and then transferred back to the mother to achieve the purpose of pregnancy. In the process of IVF, the level of human chorionic gonadotropin (hCG) is an indicator of the success of embryo implantation. This article will elaborate the relationship between the HCG value of IVF and pregnancy results from four aspects.
1. What is HCG?
HCG (Human Chorionic Gonadotropin), also known as human chorionic gonadotropin, is a hormone released by embryos. From the implantation of the fertilized egg to the early development of the embryo, the embryo will release HCG into the maternal blood. Therefore, the implantation and development of embryos can be understood by detecting the HCG level in maternal blood.
When the IVF is successfully implanted, the embryo begins to release HCG, and its level will gradually rise. Generally, the first HCG measurement is performed within 12 to 14 days after embryo implantation to determine whether the pregnancy is successful.
2. Relationship between HCG value and pregnancy results
There is a certain relationship between HCG value and pregnancy results. Next, we will discuss from two aspects.
2.1 HCG value is too low
If the HCG value is too low, it may mean that the embryo implantation is not successful or the development is blocked. In the process of IVF, when the HCG value is lower than the normal range, there may be risks of abnormal embryonic development, poor implantation or early abortion. At this time, the doctor will judge the pregnancy according to the change of HCG value and other signs, and may take corresponding treatment measures.
2.2 HCG value rises gradually
Under the condition of normal embryo development, the HCG value will gradually increase. Generally, the HCG value will double within 48 hours after the implantation of the fertilized egg, and then continue to rise at different rates. If the HCG value can rise steadily, it is generally considered as a good pregnancy indicator. The healthy development of embryos can be preliminarily judged by tracking the changes of HCG values.
2.3 Abnormal HCG value
Sometimes, after successful embryo implantation, the change of HCG value may not be satisfactory. For example, the growth rate of HCG value is slow, fluctuates greatly or stagnates. This may mean that the implanted embryo has abnormal development, or there are other pregnancy complications, such as ectopic pregnancy. When the HCG value is abnormal, the doctor may conduct further inspection to determine the pregnancy.
3. Hospital case analysis
Taking a regular hospital as an example, through a lot of observation and research, it is found that there is indeed a certain relationship between HCG value and pregnancy results in the process of IVF.
In the actual operation of the hospital, it is rare that the HCG value is too low. In general, when the HCG value is lower than the normal range, the doctor will think that the pregnancy failed and recommend the second test tube baby. It is common for the HCG value to increase gradually. The hospital makes a preliminary judgment on the pregnancy result of test tube babies by tracking the change of HCG value. In addition, the hospital will also pay close attention to whether the HCG value is abnormal and its relationship with other clinical symptoms, so as to conduct a comprehensive pregnancy assessment.
4. Summary
There is a relationship between the HCG value of IVF and pregnancy results. A low HCG value may mean poor implantation or dysplasia, and a gradual increase in HCG value is usually an indicator of a good pregnancy. However, there may be differences in each case, so doctors need to judge and deal with it according to the specific situation. Through the actual case analysis of the hospital, we can see that doctors actively pay attention to the change of HCG value in the process of IVF, so as to guide the evaluation and follow-up treatment of pregnancy results.
In the medical process related to IVF, HCG value, as an important indicator, has certain reference value for judging the pregnancy results, but it cannot determine everything alone. Combined with doctors' comprehensive judgment and other clinical symptoms, IVF pregnancy results can be better evaluated.
