How to identify the omens of successful IVF transplantation
IVF is an assisted reproductive technology, which enables couples unable to conceive naturally to realize their reproductive dreams through in vitro fertilization and embryo transfer. In the process of IVF transplantation, it is very important for couples to identify the precursors of success, which can help them judge whether they need to take further medical measures. Next, we will elaborate on how to identify the precursors of successful IVF transplantation from four aspects: embryonic development, implantation symptoms, blood hCG levels and temperature changes.

1. Embryo development
After IVF transfer, the embryo begins to develop, and the precursor of success is often accompanied by the normal growth of the embryo. First, within 7-14 days after transplantation, the embryo will be implanted, that is, the embryo will be implanted into the inner wall of the uterus and begin to grow. Women may experience some mild bleeding, called implantation bleeding. In addition, some women may also feel mild abdominal pain, which is a precursor of normal embryonic development.
Then, in the third week of embryonic development, the embryo begins to form the fetus and placenta. At this time, the mother of test tube baby may have symptoms such as breast pain and breast congestion. These symptoms indicate changes in hormone levels in the body and normal embryonic development.
Finally, an important symbol of successful embryonic development is the emergence of heartbeat. When the embryo grows to a certain extent, doctors can observe the heart beat of the embryo through ultrasonic examination. This is the exact evidence of the success of IVF transplantation.
2. Implantation symptoms
After successful IVF transplantation, women may have some special implantation symptoms. These symptoms include breast pain, breast slight swelling, abdominal distension, abdominal pain, and sometimes accompanied by vaginal bleeding. The appearance of these symptoms indicates that the embryo is successfully implanted and the endometrium is affected.
However, the intensity and timing of implantation symptoms may vary for each woman. Some people may have more obvious symptoms, while others may only have mild discomfort. Therefore, we can not judge the success of IVF transplantation by only relying on the implantation symptoms, but need to make a comprehensive assessment combined with other factors.
3. Blood hCG level
HCG (human chorionic gonadotropin) is a hormone secreted by the chorion and placenta of early embryos after pregnancy. After successful IVF transplantation, the level of hCG in women will gradually increase. Through blood examination, the concentration of hCG can be measured, so as to preliminarily judge whether the IVF transplantation is successful.
Generally, the first blood hCG test is performed about 11 days after transplantation. If the level of hCG is higher than a certain threshold (usually 5-50mIU/mL), it may indicate the success of IVF transplantation. However, it should be noted that the level of hCG cannot completely determine whether the pregnancy is stable, and further observation of the development of the embryo is needed.
4. Temperature change
The change of body temperature can also provide some reference in the precursor of successful IVF transplantation. After ovulation, the basic body temperature of women will rise and remain at a high level. If the body temperature keeps rising after transplantation, it indicates that the hormone level has changed, which may be the expression of successful embryo implantation.
However, the change of body temperature is not very accurate in judging the precursor to the success of IVF transplantation, because everyone's body temperature change may be different and affected by many factors. Therefore, it is not reliable to judge the success of IVF transplantation solely by the change of body temperature, and other factors need to be comprehensively considered for evaluation.
Summary
The differentiation of the omens of successful IVF transplantation can be evaluated from four aspects: embryonic development, implantation symptoms, blood hCG levels and temperature changes. The normal process of embryonic development, specific implantation symptoms, the rise of blood hCG level and the change of body temperature may all indicate the precursor of successful IVF transplantation. However, these indicators cannot be used alone to judge whether IVF transplantation is successful or not. It is necessary to comprehensively consider and further observe the development of embryos to make an accurate judgment.
