IVF is a common assisted reproductive technology. Pregnancy and fertility can be achieved by completing fertilization and embryo culture in the laboratory and transferring high-quality embryos to the mother's uterus. The following is a detailed introduction to the operation process of IVF transplantation from four aspects.

1. Preliminary preparation

Before IVF transplantation, the doctor will conduct a comprehensive physical examination and fertility history inquiry for both the husband and wife to understand the patient's physical condition and the cause of fertility disorder. At the same time, the woman needs to prepare for baby simulation, that is, use hormone drugs to regulate the menstrual cycle and promote the development of multiple eggs in the ovulation cycle. This can increase the probability of successful transplantation. The second step is female ovarian stimulation and follicle monitoring. The doctor will prescribe corresponding hormone drugs according to the woman's physical condition, and regularly monitor the development of follicles and the thickness of endometrium. Monitoring is carried out by ultrasound or blood detection to ensure the best condition of eggs and endometrium. Finally, the doctor will determine the time of egg collection according to the monitoring results. Usually, when the follicle develops to a certain size, mature eggs are collected by transvaginal ultrasound guided fine needle puncture. Local anesthesia is required during the collection process to ensure that patients will not feel pain.

2. Fertilization and embryo culture

The collected eggs will be immediately sent to the laboratory for fertilization. The man combines the sperm with the egg to form an embryo through manual semen extraction. The fertilized eggs will be cultured in the culture dish to provide appropriate temperature, humidity and nutrition environment. The process of embryo culture usually lasts for 3 to 5 days, during which the doctor will carefully observe the development of the embryo. The common embryo stages include two cell stage, four cell stage and eight cell stage. According to the quality and development of embryos, doctors will select the most promising embryos for transplantation.

3. Embryo transfer

Embryo transfer is a key step in IVF. Doctors will use thin tubes to transport selected embryos through the vagina to the endometrium. This process is painless and usually does not require anesthesia. After embryo transfer, patients need to rest for a period of time, usually 30 minutes to 1 hour. This period of rest is conducive to better embryo implantation and implantation. A few days after transplantation, patients need to follow the doctor's instructions, avoid strenuous exercise and sexual life, and ensure adequate rest and relaxation.

4. Pregnancy and prenatal examination

After successful transplantation, the patient will enter the pregnancy stage. Usually about two weeks after transplantation, pregnancy can be confirmed by urine or blood test. If the result is positive, the patient needs to contact the doctor in time to arrange the follow-up maternal inspection and health care. Maternity examination includes ultrasonic examination, blood examination and physical examination. These tests can monitor the development of the embryo, the physical condition of the mother and the health of the fetus. The doctor will give guidance and advice according to the examination results, and ensure the safe and smooth progress of pregnancy. To sum up, IVF is a complex and sophisticated medical technology, including preliminary preparation, fertilization and embryo culture, embryo transfer, pregnancy and prenatal examination. Through scientific operation process and professional medical team, IVF transplantation has brought hope for infertile couples to realize their reproductive aspirations.
