How to determine the expected date of IVF

In vitro fertilization (IVF) is a way to help achieve pregnancy through in vitro fertilization (Basic Information on IVF). Generally, the calculation method of the expected date of IVF is different from that of natural pregnancy. The time of embryo transfer, progesterone monitoring, the special situation of pregnant women with test tube babies and other factors need to be taken into account when the test tube baby is due. This article will discuss how to determine the expected date of delivery of IVF from four aspects: ultrasound examination, embryo transfer time, progesterone monitoring and special conditions of IVF pregnant women.

1、 Ultrasonic examination

Ultrasonography is one of the important tools to determine the expected delivery date of test tube babies. Through ultrasonic examination, doctors can understand the development of embryos and predict the expected date of delivery. Usually, the first ultrasound examination is performed within two weeks after embryo transfer. The doctor will observe whether there is embryo implantation in the uterus, the size of the embryo and the heartbeat of the embryo. According to the size and heartbeat of the embryo, doctors can preliminarily estimate the expected date of delivery. Subsequent ultrasound examination will further determine the development of the embryo, so as to determine the expected date of delivery more accurately. In addition, ultrasound can also determine whether multiple pregnancy. Multiple pregnancy is related to multiple embryo transfer during IVF. The due date of multiple pregnancy needs special consideration and management, so ultrasound is of great significance in predicting the due date and the number of embryos.

2、 Embryo transfer time

The time of embryo transfer is another important factor in the expected delivery of IVF. According to the date of embryo transfer, doctors can predict the time of embryo development in the uterus and calculate the expected date of delivery accordingly. After embryo transfer, it is usually necessary to wait about two weeks for ultrasonic examination to confirm pregnancy and determine the size and development of the embryo. Generally speaking, the earlier the embryo transfer time is, the earlier the expected delivery date will be.

3、 Progesterone monitoring

In the process of IVF, progesterone monitoring is one of the important means to determine the expected date of delivery. Progesterone is a metabolite of luteinizing hormone, which plays an important role in early pregnancy. Progesterone monitoring is mainly to assess the progress of pregnancy by detecting the level of progesterone in blood or urine samples. According to the change trend of progesterone, doctors can infer the development of embryos and then calculate the expected date of delivery.

4、 Special situation of pregnant women with test tube babies

The special circumstances of IVF pregnant women will also have an impact on the determination of the expected date of delivery. For example, factors such as age, basic diseases, and maternal physical conditions may lead to the advance or delay of IVF's due date. For older pregnant women, doctors usually have a more cautious estimate of the expected date of IVF delivery. In addition, the basic diseases of pregnant women, such as hypertension and diabetes, will also affect the determination of the expected date of delivery.

summary

The determination of the expected date of IVF needs to be considered from many aspects. Ultrasound examination, embryo transfer time, progesterone monitoring and special conditions of test tube baby pregnant women are all important factors affecting the expected date of delivery. Ultrasonography can observe the size and development of the embryo and whether there is multiple pregnancy; The time of embryo transfer can be calculated according to the time of embryo development in uterus; Progesterone monitoring can assess the progress of pregnancy by detecting the level of progesterone; The special circumstances of IVF pregnant women will also have an impact on the determination of the expected date of delivery. Taking these factors into account, doctors can more accurately predict the expected delivery date of IVF, and provide better management and care for pregnant women.
