How to calculate the expected date of IVF
IVF refers to the process of combining sperm and egg through in vitro fertilization technology, and then transplanting the fertilized egg into the uterus of a woman. For the parents of IVF babies, the expected date of birth is a very important information, which helps to arrange life reasonably and prepare for the arrival of the newborn. The calculation of the expected date of birth is an accurate science, which is described below from the aspects of cycle control, embryonic development, B-ultrasound examination and IVF hospital.
Cycle control
For IVF, cycle control is a very critical step. Under the guidance of the hospital, women need to control their menstrual cycle through drugs. Usually, doctors will determine the best time to retrieve eggs according to the menstrual cycle and ovulation period of women. The fertilized eggs after taking eggs will be further cultured in the laboratory and then transplanted back to the mother. According to the time of egg retrieval and the rate of embryo development, the expected date of delivery can be initially determined.
In the cycle control, doctors will carry out multiple B-ultrasound examinations to determine the follicular development and ovulation time. These data can be compared with historical data to further improve the accuracy of the expected production date.
embryonic development
The expected date of IVF is calculated from the embryonic development time. According to the development of embryos in the laboratory, doctors can roughly determine the expected date of delivery after embryo transfer.
In the laboratory, the development stages of the embryo are divided into different levels, such as division degree, embryo morphology, etc. These information will be recorded and compared with the historical data to calculate the corresponding expected production date.
B-ultrasonic inspection
B-ultrasound plays an important role in IVF. Through B-ultrasound examination, doctors can observe the development of the embryo, the size of the fetus and the condition of the placenta.
After embryo transfer, regular B-ultrasound examination can provide a more accurate due date. The doctor will judge the fetal development and the expected date of delivery by the size of the fetus, the left umbilical cord, and the location of the placenta in the B-ultrasound image.
IVF Hospital
The calculation of the expected date of delivery is also affected by the hospital. Different hospitals have different laboratory equipment and medical technology levels. Some IVF hospitals improve the accuracy of the delivery schedule through continuous technological innovation and research. Therefore, selecting a hospital with rich experience and advanced equipment for IVF process can obtain a more accurate and reliable delivery schedule.
To sum up, there are many factors that need to be considered in the calculation of the expected date of delivery of IVF babies. Cycle control is the first step. The time point of egg retrieval is determined by ovulation time and follicular development. The development of embryos is also an important reference, and the expected date of birth is calculated by the level and morphology of embryos. B-ultrasound can provide more accurate information about the expected date of delivery. Finally, choosing an experienced and advanced IVF hospital is also an important factor in calculating the expected delivery date. Taking these aspects into account, we can get more accurate and reliable information about the expected date of IVF.
