Information about the expected date of IVF
IVF is a kind of assisted reproductive technology, which broadly includes in vitro fertilization embryo transfer (IVF-ET) and embryo transfer (ET). The calculation method for the expected date of birth of test tube baby is different from that of natural pregnancy. The following information about the expected date of birth of test tube baby is introduced from a medical perspective.
1. Calculation method of test tube baby's due date
The calculation of the expected date of IVF is mainly based on the time of fertilized egg transfer. Generally speaking, embryos before transplantation have been cultured in vitro to the five day old blastocyst stage. After transplantation, the calculation method used to predict the expected birth date of test tube babies is similar to that of natural pregnancy. The doctor will calculate the expected date of birth according to the implantation time of the test tube baby.
It should be noted that since the implantation time of IVF eggs is clear, the calculation of the expected delivery date will be more accurate, while the fertilization time of naturally pregnant women cannot be confirmed, so there will be some errors in the calculation of the expected delivery date.
In addition, the pregnancy period of IVF may be different. According to the operation procedures of different hospitals and doctors, IVF embryos can be frozen before or after transplantation, so the calculation method of the expected delivery date will be different.
2. Difference between expected date of delivery and gestational age
The expected date of IVF is different from that of traditional pregnant women. The traditional pregnant woman's due date is calculated on the first day of the last menstrual period, while the test tube baby's due date is based on the time of fertilized egg transfer.
In addition, it should be noted that the expected date of delivery and gestational age are different. The expected date of birth refers to the predicted date of birth of the baby, while the gestational age refers to the length of time the baby will grow in the womb. Because IVF embryos have generally been cultured to blastocyst stage in vitro, there is a time difference between the expected date of delivery and the gestational age. Generally speaking, the calculation method of the expected delivery date will advance the days of blastocyst transfer.
3. Variation factors of test tube baby's due date
The expectant date of IVF is affected by many factors, including embryo quality, implantation period, maternal age, etc. The better the quality of the embryo, the better the growth and development of the baby, and the expected date of delivery will generally be closer to the accurately predicted date.
Maternal age is also an important factor affecting the expected delivery date of IVF. Generally speaking, the egg quality of young women is better, so the expected date of IVF is more stable. With the increase of women's age, the egg quality will decline, and the expected date of IVF may also be advanced or delayed.
In addition, women suffering from certain diseases may need a longer period of treatment, which will also have a certain impact on the expected delivery date of IVF.
4. Hospital example: XX General Hospital
XX General Hospital is one of the well-known assisted reproductive technology hospitals in China. The hospital has first-class equipment and a professional team of doctors, committed to providing a full range of assisted reproductive technology services for infertile patients.
The hospital uses internationally advanced IVF technology to accurately calculate the expected date of delivery of IVF. The doctor will develop a personalized treatment plan according to the specific situation of each patient, and give detailed explanation and guidance for the expected delivery date.
In general, the calculation method of IVF's expected birth date is different from that of natural pregnancy, mainly based on the time of fertilized egg transfer. The expected date of delivery is different from the gestational age, and it will vary due to various factors. As a professional assisted reproductive technology hospital, XX General Hospital is committed to providing quality medical services for IVF patients.
