How to determine the expected date of IVF

IVF is a kind of assisted reproduction technology, which combines sperm and egg through in vitro fertilization, and then cultivates and implants them into the mother's body in the laboratory, finally pregnant and delivering a healthy baby. In the process of IVF, it is very important to determine the expected date of birth, which helps obstetricians and gynaecologists and pregnant women make reasonable prenatal preparations. This article will elaborate on the determination of the test tube baby's due date from the aspects of ultrasound examination, fetal size, fetal heart rate monitoring and fetal movement evaluation.

Ultrasonic inspection

Ultrasonic examination is one of the commonly used methods to determine the expected delivery date of test tube babies. Through ultrasonic technology, doctors can observe the development of the fetus in the uterus, and measure the fetal head circumference, abdominal circumference, femur length and other indicators. These data can be compared with the reference value of normal pregnancy to calculate the expected date of delivery. Generally speaking, ultrasonic examination can be more accurate in determining the expected date of delivery in early pregnancy. In the process of determining the expected date of delivery, doctors usually carry out multiple ultrasonic examinations to ensure the accuracy of the data. As the fetus develops, ultrasound can also provide other important information, such as the location of the placenta and whether the fetus is abnormal.

Fetal size

The size of the fetus is also an important indicator to determine the expected delivery date of IVF. By measuring the fetal head circumference, abdominal circumference and femur length, doctors can calculate the fetal weight and development. Generally speaking, the growth rate of fetal weight can be predicted, so by comparing the fetal size with the reference value of normal pregnancy, we can make a preliminary estimate of the expected date of delivery. However, it should be noted that the size of the fetus is not the only indicator to determine the expected date of delivery, because there may be differences in the growth rate of each baby. When determining the expected date of delivery, other factors should be considered comprehensively, such as ultrasonic examination and fetal heart rate monitoring.

Fetal heart rate monitoring

Fetal heart rate monitoring is a means to determine the due date of delivery by recording the fetal heartbeat. Generally speaking, in the middle and later stages of pregnancy, doctors will use the fetal heart monitor to monitor the fetal heartbeat. By observing the change of fetal heart rate, we can judge whether the fetus is developing normally and predict the expected date of delivery. Fetal heart rate monitoring is a non-invasive inspection method, which is safe and reliable for both mother and fetus. By continuously monitoring the heartbeat of the fetus, doctors can find the abnormalities of the fetus in time and take corresponding measures.

Fetal movement assessment

Fetal movement assessment is a method to determine the expected date of delivery by observing the fetal movement. In the late pregnancy, the frequency and intensity of fetal movement will gradually increase. Generally speaking, the number of fetal activities per day should be more than 10. By observing the fetal movement, we can preliminarily judge whether the fetal development is normal and predict the expected date of delivery. Fetal movement assessment is a simple and convenient method, and expectant mothers can observe by themselves. If you notice that fetal movement decreases or stops, you should consult your doctor in time to rule out the possibility of fetal abnormalities. To sum up, the determination of the test tube baby's due date can be carried out by various methods, such as ultrasonic examination, fetal size, fetal heart rate monitoring and fetal movement evaluation. These methods can be used alone or in combination to improve the accuracy and certainty of the expected production date. Through the scientific determination of the expected date of birth, obstetricians and gynaecologists and pregnant women can make appropriate prenatal preparations to ensure the safe delivery of test tube babies and the health of mothers and babies.
