Specific steps of IVF

IVF is a method of assisted reproductive technology. Fertilization is achieved by culturing the fertilized egg to a certain stage of development in the laboratory, and then implanting it into the female uterus. The specific steps of IVF need to be carried out under specific experimental conditions to ensure the success rate and infant health.

1. Preliminary preparation of IVF

Before IVF, the doctor will conduct a series of examinations and evaluations on the couple to determine whether this process is suitable. These assessments included female ovarian function, uterine morphology, and male semen quality. In addition, couples also need genetic counseling and psychological counseling to ensure that they are ready for the physical and psychological preparations brought by the IVF process. Then, women need to receive ovulation promoting drugs to promote the growth and development of eggs. During the treatment, doctors will monitor the development of eggs through ultrasound and blood testing. Once the egg is mature, the doctor will determine the best time to retrieve the egg.

2. Egg taking and sperm treatment

Fetching eggs is a key step in IVF. Before taking eggs, women need to receive general anesthesia or local anesthesia. Doctors use ultrasound guided puncture technology to insert a fine needle into the ovary and extract the eggs from the follicle. This process generally requires monitoring and lasts for several minutes. At the same time, men need to provide fresh semen samples or cryopreserved sperm. After the sperm is treated, the best quality sperm is selected to combine with the egg.

3. Fertilization and embryo culture

Eggs and sperm are cultured and combined in the laboratory. Doctors put eggs and sperm together in a culture dish for in vitro fertilization. Sometimes, if sperm quality is poor or there are other problems, doctors may choose to use single sperm injection technology (ICSI). After fertilization, the egg will continue to be cultured in the laboratory until it develops into a multi cell embryo. The process of embryo development usually lasts for several days, and doctors will evaluate and monitor the embryo to select the best embryo for transplantation.

4. Embryo transfer and pregnancy

Once the best embryo is selected, the doctor will transplant it back into the female uterus. This process generally does not require anesthesia, and the embryo is placed in a suitable position through a thin tube (catheter). After transplantation, women need to rest for a period of time and receive supportive treatment to improve the success rate of pregnancy. If the embryo is successfully implanted and develops, the woman will become pregnant. The doctor will monitor the pregnancy to ensure the normal development of the fetus. In early pregnancy, doctors may carry out hormone therapy to support the stability of pregnancy.

summary

The specific steps of IVF need to be carried out under specific experimental conditions. The first is the preparation stage, including assessment, examination and psychological guidance. Then, take eggs and sperm to ensure high-quality eggs and sperm. Next is fertilization and embryo culture, which needs to be carried out under optimized culture conditions. The last is embryo transfer and pregnancy. The doctor will select the best embryo for transfer, and monitor and support the pregnancy. The success rate of IVF is related to the health of the baby and the experimental conditions, the doctor's experience and the couple's own conditions. Therefore, it is crucial to choose a hospital with professional experience and leading equipment when carrying out IVF.
