Gestational age is a medical term used to refer to the length of time the fetus is in the womb, doctors will calculate the gestational age from the time the egg meets the sperm and forms an embryo, the unit used is weeks of age.
IVF (in vitro fertilization) is the most effective method of assisted reproduction for cases of infertility, subfertility, genetic problems related to sex when other methods of assisted reproduction such as medication or artificial insemination failed. In particular, IVF technology has the potential to help women carry multiple pregnancies at the same time by transferring multiple embryos into their uterus, also known as multiple pregnancy.
How to calculate IVF gestational age is similar to how to calculate fetal age during natural pregnancy, this will help pregnant mothers monitor the development of the fetus as well as the health of the baby. In particular, knowing how to calculate gestational age after embryo transfer in IVF will help mothers a lot in identifying potential risk factors for the fetus.

Normally, the fetus after being formed will develop through many stages, each stage of the fetus will have different development and effects on the mother, this will help pregnant women prepare for both. psychologically and nutritionally appropriate during pregnancy. Since gestational age is calculated from the time the fetus is conceived, any gestational age calculation including IVF gestational age calculation must be calculated from that point.
Calculation of IVF gestational age is not calculated from the date of embryo transfer into the body because by the time the embryo is transferred to the uterus, the embryo has been formed for a while and developed to a certain extent. After the embryo is formed more than 2 weeks, it will be put into the woman's body, so the gestational age calculation will be calculated by the time the embryo is transferred to the woman's uterus and then added 2 weeks.

How to calculate IVF gestational age is as follows:
If the embryo transfer is performed on the 3rd day, when calculating the fetal age, you will have to add the time the embryo is in the uterus with 2 weeks and 3 days. If the embryo transfer is performed on day 5, when calculating the fetal age, the time the embryo is in the uterus must be added with 2 weeks and 5 days. Pregnant women performing IVF can rely on the above calculation of gestational age to accurately know the number of weeks of pregnancy and provide appropriate care.
