Grading criteria for test tube infants
In vitro fertilization (IVF) refers to the transfer of fertilized eggs into the mother's uterus for development. In order to evaluate the development and health of IVF, doctors usually use IVF grading criteria. The content of IVF grading standards is described in detail from the aspects of pre pregnancy inspection, embryo assessment, pregnancy monitoring and birth assessment.

Pre pregnancy examination
Before the implementation of IVF technology, doctors will conduct a series of pre pregnancy examinations for couples. First, men need to conduct semen analysis to assess the quality and quantity of semen. Then, women need to measure the endometrial thickness and assess the ovarian function to ensure that the intrauterine environment is suitable for the implantation of fertilized eggs and the development of embryos.
In addition, doctors will screen couples for genetic diseases to avoid adverse effects of genetic diseases on offspring. The genetic counselor will provide relevant advice based on the couple's family history and risk assessment of genetic diseases.
The purpose of pre pregnancy inspection is to ensure the quality and health of the fertilized eggs by comprehensively evaluating the physical condition of the couple.
Embryo evaluation
Embryo evaluation is one of the core links of IVF technology. It judges the development degree and quality of the embryo by evaluating the appearance and internal structure of the fertilized egg.
The evaluation indexes included the division of the fertilized egg, the number of cells, the morphology of the cell body and the formation of the embryo cavity. Doctors will divide embryos into four grades according to these indicators: high quality, good, average and poor. High quality embryos with high implantation and development potential were selected to be transplanted into the mother's uterus.
The purpose of embryo evaluation is to maximize the success rate of IVF and the birth rate of healthy infants.
Pregnancy monitoring
Once the pregnancy is successful, the doctor will conduct regular pregnancy monitoring for the mother of IVF. By checking the weight, temperature, blood pressure, urine and other indicators of pregnant women, doctors can understand the growth of embryos and the health status of pregnant women.
In addition, doctors also conduct blood tests to detect the blood parameters, hormone levels and genetic disease risks of pregnant women. Regular ultrasonic examination is essential. The growth and development of the embryo can be understood by observing the size, shape and heartbeat of the embryo.
The purpose of pregnancy monitoring is to find and deal with the possible health problems of pregnant women and fetuses in time to ensure smooth pregnancy and safe delivery.
Birth assessment
When the IVF baby is born successfully, the doctor will perform a birth assessment on the newborn. Birth assessment usually includes measuring the height, weight, head circumference, chest circumference and other indicators of the baby to assess the health status of the baby.
In addition, doctors will also carry out newborn hearing screening and congenital disease screening to ensure that the baby's hearing and physical development are normal.
The purpose of birth assessment is to confirm the development and health status of test tube babies, and take corresponding nursing measures to ensure the healthy growth of babies.
Summary
The IVF grading standard is a set of standards used to evaluate the development and health status of IVF infants. From the aspects of pre pregnancy inspection, embryo evaluation, pregnancy monitoring and birth evaluation, doctors ensure the success rate of IVF and the birth rate of healthy babies through detailed inspection and evaluation. The application of these scoring standards will help to increase the success rate of IVF technology and help those couples who cannot conceive naturally realize their reproductive dreams.
