How to calculate the expected date of IVF

Test tube baby refers to the baby who transfers the fertilized egg into the mother through in vitro fertilization technology, promotes the fertilized egg to develop into an embryo and successfully conceives. How to accurately calculate the expected date of IVF is very important for families. The following four aspects will be described in detail.

1. Calculate the expected delivery date based on the migration date

The expected date of delivery of IVF can be determined by calculating the number of gestational weeks from the date of transplantation. Usually, the transfer is carried out on the third to fifth day after fertilization, and the most common is the embryo transfer on the fifth day. If an embryo is transferred to the mother on the fifth day, the expected delivery date is the transfer date plus about 280 days. Of course, this is only a rough estimate, because not all IVF embryos are transferred on the fifth day. In addition, in some cases, blastocyst transfer may be carried out, in which case the calculation of the expected birth date will be based on the date when the embryo is cultured to the blastocyst (the fifth or sixth day of development).

2. Estimating the expected date of delivery based on embryonic development

The expected date of IVF can also be estimated based on the development of embryos. In the process of embryo culture, the embryo will go through the stages of division and development, and the number of divisions and the degree of embryo development can usually be tracked. According to the development of the embryo, doctors can estimate the expected date of delivery. However, this method is not particularly accurate because the rate of development of each embryo may vary.

3. Calculation of expected production period through ultrasonic inspection

Ultrasonic technology is a very common method, which can be used to determine the expected delivery date of test tube babies. By detecting the size and development of the fetus, doctors can accurately calculate the expected date of delivery. Generally speaking, ultrasonic examination will be carried out in the early pregnancy, because it can more accurately determine the size and development of the fetus. With the progress of pregnancy, the calculation of the expected date of delivery depends more on the size and development of the fetus.

4. Calculate the expected date of delivery according to the menstrual cycle of pregnant women

The expected date of IVF can also be calculated by the menstrual cycle of the pregnant woman. First, it is necessary to determine the length of a pregnant woman's menstrual cycle, that is, the number of days from the start date of the cycle to the start date of the next cycle. Then, determine the length of the pregnant woman's menstrual cycle, that is, the number of days from the start date of menstruation to the start date of the next cycle. With these two data, the most likely date of conception can be calculated, and then the expected date of delivery can be calculated.

Summary

There are many methods to calculate the expected date of birth of test tube babies. Based on the date of transfer, embryo development, ultrasound examination and the menstrual cycle of pregnant women, IVF is commonly used to predict the expected date of delivery. However, each method has its limitations, and can not predict the expected date of delivery completely and accurately. Therefore, it is recommended to cooperate with the professional medical team and make a comprehensive judgment according to the specific situation, so as to estimate the expected date of IVF more accurately.
