How to judge the success of IVF transplantation?
IVF is an assisted reproductive technology that artificially transfers the fertilized eggs into the mother's uterus to help couples who cannot conceive naturally realize their reproductive dreams. However, the success rate is not 100%, and it needs to be judged from many aspects to determine whether it is successful or not. The following will elaborate on the judgment of successful IVF transplantation from four aspects: embryonic development, hormone level, pregnancy test and ultrasound examination.
Embryo development
Embryo development is one of the most important signs of success of IVF. Usually, the hospital will evaluate the embryonic development within ten days to two weeks after transplantation. By observing the survival status, cell division and morphological changes of the embryo, we can judge whether the embryo has successfully embedded in the uterine wall and further developed into an embryo sac. If the embryo develops smoothly, its peripheral cells will gradually thicken, the inner capsule will gradually expand, and the embryonic endogerm will also form. If the embryo fails to develop, the embryo will not be able to embed into the uterine wall, leading to pregnancy failure.
In the process of embryo development, hospitals usually conduct multiple embryo evaluations to ensure the normal development of embryos. If multiple embryos are transferred at the same time, the hospital can also select the most likely one for pregnancy according to the development of the embryo. Therefore, the success of IVF can be preliminarily judged through the evaluation of embryo development.
In addition, the hospital will also carry out luteal function test to determine whether the luteal function is normal by detecting the levels of progesterone, estradiol and other hormones. Normal corpus luteum function is very important for the development of embryos and the maintenance of pregnancy. Therefore, whether the corpus luteum function is normal or not is also an important indicator for judging the success of IVF transplantation.
Hormone levels
After the success of IVF transplantation, a series of changes will occur in the hormone levels of women. The success of transplantation can be judged by detecting the changes of hormone levels. Generally, within two weeks after transplantation, the hospital will detect the levels of progesterone, estrogen, human chorionic gonadotropin (hCG) and other hormones in the blood. Progesterone and estrogen are important hormones for maintaining pregnancy, and their elevated levels can indicate the occurrence of pregnancy. HCG is a hormone produced after embryo implantation, and the increase of its level indicates that the embryo has successfully embedded into the uterine wall.
Hormone level detection needs to be carried out many times to observe whether the hormone level is stable and gradually rising. If the hormone level continues to rise and reaches the normal pregnancy level, the success of IVF transplantation can be preliminarily judged. However, the changes of hormone levels need to be judged comprehensively in combination with other factors, because sometimes abnormal hormone levels may also lead to pregnancy failure.
Pregnancy test
Pregnancy test is another important index to judge the success of IVF transplantation. Generally, women can have a urine pregnancy test about two weeks after transplantation. This test detects the level of hCG in urine to determine whether pregnancy occurs. If the urine pregnancy test paper shows positive, it indicates that the hCG level has exceeded the detection sensitivity, that is, pregnancy has occurred.
However, the urine pregnancy test cannot be 100% sure of the success of pregnancy, because sometimes the level of hCG in urine may be low, or other factors may interfere with the test results. Therefore, further examination is needed to confirm whether the pregnancy is successful.
Ultrasonic examination
Ultrasonography is one of the most intuitive and reliable methods to judge the success of IVF transplantation. Generally, women can have their first ultrasound examination around 6-7 weeks of pregnancy. The shape and size of the embryo were observed through the reflection and echo of ultrasound to determine whether the embryo was successfully embedded in the uterine wall and developed normally.
In the ultrasonic examination, the doctor can clearly see the heartbeat of the embryo, the development of the embryo bud and the size of the embryo sac. If ultrasound examination shows that the development of embryo sac and embryo bud is normal, and there is obvious heartbeat, it indicates that the IVF transfer is successful. Since then, the hospital will regularly carry out ultrasonic examination to monitor the development of the fetus and ensure the smooth progress of pregnancy.
To sum up, the success of IVF can be preliminarily determined by judging the embryonic development, hormone level, pregnancy test and ultrasound examination. However, because everyone's situation is different, the success or failure needs to be combined with the comprehensive judgment of doctors. It is hoped that these judgment indicators can help couples to obtain pregnancy results in time after IVF transplantation and realize their reproductive dreams.
