Time of IVF successful confirmation
IVF technology is an assisted reproductive technology. The fertilized egg is cultivated to a certain stage through in vitro fertilization, and then implanted into the patient's uterus for pregnancy. In the IVF process, there are usually several aspects to consider when confirming success. The following will elaborate on the time of successful confirmation of IVF from four aspects: embryonic development after transplantation, patient blood test, B-ultrasound examination and pregnancy test paper test.
Embryo development after transplantation
After IVF transplantation, embryo development is one of the important indicators to determine whether it is successful or not. Generally speaking, the third day after transplantation can be preliminarily judged by the number of cells in the embryo. Under normal circumstances, the three-day embryo should be in six or eight cell stage. The survival rate of multicellular embryos is relatively high and they are well developed. Therefore, it can be preliminarily identified as the success of IVF transplantation. However, due to individual differences, different hospitals have certain differences, so it needs to be determined by combining other inspection methods.
From the seventh day to the tenth day after transplantation, the success of IVF can also be confirmed by measuring the concentration of chorionic gonadotropin (hCG) in urine or blood. After embryo implantation, the hCG released from the embryo can be detected. If the hCG concentration is higher than the reference value, the embryo has been successfully implanted, which means that the IVF transfer is successful.
In the hospital, the blood hCG concentration can be detected about 14 days after the conventional transplantation to confirm whether the test tube baby is successful. If the result is positive, it indicates that the embryo has been successfully implanted, and the patient is successfully pregnant.
Blood test
Blood test is one of the important means to confirm the success of IVF. After IVF transplantation, progesterone, estradiol and β- The concentration of hCG and other substances was used to determine whether the transplantation was successful.
Progesterone is a hormone secreted by corpus luteum during pregnancy, which can be used to judge whether the embryo is successfully implanted. Under normal circumstances, the progesterone concentration will gradually increase after embryo implantation. If the progesterone concentration exceeds the reference value, the IVF transfer is successful.
Estradiol is a hormone secreted by ovarian corpus luteum after embryo implantation, and the increase of its concentration can also be one of the bases for the success of IVF. In the case of successful transplantation, the concentration of estradiol will gradually increase.
In addition, β- HCG is another hormone that can be detected by blood tests. After IVF transplantation, if β- The continuous increase of hCG concentration can confirm the successful implantation of embryos and the success of IVF transplantation.
B-ultrasonic inspection
After the success of IVF transplantation, doctors usually carry out B ultrasound examination about two weeks after transplantation to confirm whether it is successful. The position and shape of the embryo in the uterus can be observed by B-ultrasound. If the doctor can see a normal developing embryo in the uterus during the B-ultrasound examination, it means that the IVF transfer is successful.
In addition, B-ultrasound can also determine whether the fetal sac of the test tube baby develops normally and whether there is fetal heart beat in the fetal sac. These are important indicators to confirm the success of IVF, which can be clearly observed by B-ultrasound.
Pregnancy test paper test
The pregnancy test is a simple and convenient test method, which can be carried out at home. Generally speaking, after IVF transplantation, patients can perform test paper test about 10 days after transplantation.
Test paper test is used to determine whether there is hCG in urine that can be detected by urine pregnancy test paper. If the test paper test shows two red lines (some brands may be of other colors), the IVF transplantation is successful.
It should be noted that although the test paper test results may have some accuracy errors, they can be used together with other inspection methods to more accurately judge whether the IVF is successful.
Summary:
The success of IVF can be confirmed by many methods, such as embryonic development after IVF transplantation, patient blood test, B-ultrasound examination and pregnancy test paper test. First, the embryo implantation can be preliminarily judged by the detection of the number of cells and the concentration of hCG in the embryo. Secondly, progesterone, estradiol and β- The concentration of hCG and other hormones can further confirm the success of IVF. In addition, B ultrasound can visually observe the position and shape of the embryo in the uterus, further confirming the success of IVF. Finally, the pregnancy test paper test is a simple test method that can be used at home to preliminarily judge whether the test tube baby is successful.
To sum up, the success of IVF can be confirmed through the comprehensive use of various inspection methods. After receiving IVF technology, patients can choose appropriate examination methods according to the doctor's suggestions, so as to timely understand the success of IVF.
