What is the calculation process of IVF's expected date of birth?



Calculation process of test tube baby's due date

IVF refers to the method of artificial pregnancy, in which the fertilized eggs and sperm are cultured and grown in vitro, and then the fertilized eggs are transplanted into the mother's uterus for development, ultimately assisting the patient to successfully conceive. The calculation of the expected date of birth is crucial for the successful implementation of IVF. This article will elaborate on the calculation process of the expected delivery date of IVF from the following four aspects.

Step 1: Start based on the date of fertilized egg transfer

The estimated date of IVF is calculated from the date of fertilized egg transfer. After a successful IVF embryo transfer, women are often advised to observe for 14 days to detect pregnancy. Within 14 days, doctors usually conduct blood or urine tests to detect whether a woman is pregnant. If the test result is positive, the calculation of the expected birth date of the test tube baby will start from this date. This means that the 14 day period will be regarded as the beginning of pregnancy, and will be used to calculate the expected date of IVF.

Step 2: Calculate according to women's menstrual cycle

The estimated date of IVF can also be calculated through the menstrual cycle of women. For women with normal menstrual cycle, the calculation process is relatively simple. Usually, the calculation of the expected date of birth is based on the first day of the last menstrual period and the duration of the cycle. In this case, the expected date of delivery is the first day of the menstrual cycle plus 280 days (average delivery cycle).

Step 3: Calculate with ultrasonic inspection

Ultrasonic technology is one of the reliable methods to determine the expected delivery date of test tube babies. About 6 to 7 weeks after IVF transplantation, doctors will use ultrasound to check the development of the fetus. According to the size and development of the fetus, doctors can initially determine the expected date of birth. Usually, ultrasound will confirm the exact development period of the fetus and calculate the expected date of birth based on this information.

Step 4: Calculate according to the signs and symptoms of pregnant women

The expected date of IVF can also be calculated according to the maternal signs and symptoms. Pregnant women often experience pregnancy reaction, weight gain, uterine growth and other changes. These changes can correspond to the actual pregnancy period and are related to the expected date of IVF. Doctors usually make a preliminary estimate of the expected date of delivery based on these signs and symptoms. To sum up, the calculation process of IVF baby's expected delivery date includes four aspects: based on the start of the fertilized egg transfer date, based on the women's menstrual cycle, based on ultrasonic examination, and based on the pregnant women's signs and symptoms. These methods comprehensively consider many factors, and can calculate the expected date of IVF as accurately as possible. In actual clinical operation, doctors will select appropriate calculation methods according to the specific conditions of patients and make appropriate adjustments to ensure the safe and smooth birth of IVF.
