How to judge the stability of test tube babies for several weeks
The development of IVF technology has enabled many infertile couples to successfully realize their desire to have children. However, in the process of IVF, it is very important to understand the development of embryos and judge the stability of embryos. The following details how to judge the stability of test tube babies in a few weeks from aspects such as ultrasound examination, embryo quality score, corpus luteum monitoring and blood test.

Ultrasonic examination
Ultrasonography is one of the important methods to evaluate the development of IVF embryos. After IVF embryo transfer, the first ultrasonic examination is usually carried out in the second week after transfer to determine whether the embryo is successfully implanted. Thereafter, ultrasonic examination was carried out every 1-2 weeks to observe the development of embryos.
Ultrasonic examination can use the characteristics of ultrasound to show the shape and size of the embryo and determine the stability of the embryo for several weeks. By measuring the length of the head and buttock of the embryo, the heart rate of the embryo and other parameters, we can judge the weeks of the embryo. Generally speaking, the length of the head and buttock of the embryo corresponds to the number of weeks of pregnancy. The better the development of the embryo, the more the length of the head and buttock conforms to the standard of the corresponding number of weeks.
In addition, ultrasound can also observe the heartbeat of the embryo to determine whether the embryo is healthy and stable. Under normal circumstances, the heart rate of the embryo should be between 100-150 beats per minute, and the heart rate should be regular and strong.
Embryo quality score
Embryo quality score is one of the important methods to evaluate the development and stability of IVF embryos. In the process of in vitro culture of embryos, professional doctors will evaluate the quality of embryos according to the number of cells, morphology, symmetry, landing surface, cytoplasm and nucleus.
Generally speaking, the more the number of embryos, the better the quality, and the greater the possibility of stability in a few weeks. Symmetry of embryo morphology and normal structure of cytoplasm and nucleus are also important indicators for evaluating embryo quality. According to the quality score, doctors can judge that the embryo is stable for several weeks, and select the best embryo for transplantation to improve the success rate.
At the same time, after embryo transfer, doctors will monitor the development of the embryo according to the quality score results to judge the stability of the embryo. The quality score can help couples understand the development of embryos and make corresponding adjustments and decisions.
Corpus luteum monitoring
Luteal monitoring is one of the important methods to judge the stability of test tube babies in a few weeks. After successful embryo transfer, corpus luteum begins to secrete progesterone to maintain the stability of endometrium and the survival of embryos. By monitoring the level of lutein, we can understand the development of embryos.
Progesterone and estradiol are the main luteal hormones. Progesterone level can reflect the function of corpus luteum and embryonic development. Generally speaking, IVF infants with normal progesterone levels are more likely to be stable in a few weeks. By regularly monitoring the level of luteal hormone, abnormal conditions can be found in time and corresponding intervention measures can be taken.
blood analysis
Blood test is also one of the important methods to judge the stability of test tube babies for several weeks. After embryo implantation, maternal blood progesterone and human chorionic gonadotropin (hCG) levels will increase. By regularly detecting the levels of progesterone and hCG in the blood, we can judge the development of embryos and the possibility of stability for several weeks.
The levels of progesterone and hCG will gradually increase under normal embryonic development, and may be unstable or decreased under abnormal conditions. Blood test is a direct and accurate method to judge the embryonic development, which can provide scientific basis for adjustment and decision-making in the process of IVF treatment.
Summary
The stability of test tube babies in several weeks can be comprehensively judged by ultrasound, embryo quality score, corpus luteum monitoring, blood test and other methods. Ultrasound can observe the morphology and heartbeat of embryos, embryo quality score can evaluate the development of embryos and select the best embryos, corpus luteum monitoring can understand the function of corpus luteum and the development of embryos, and blood test can directly judge the development of embryos. The comprehensive application of these methods can improve the understanding and intervention of IVF development and provide strong support for couples to achieve healthy birth.
