Steps of putting test tube baby into uterus
IVF is a kind of assisted reproductive technology. After the fertilized egg is cultivated to a certain stage through in vitro fertilization, it is put into the patient's uterus for pregnancy. The following will introduce in detail the steps of putting IVF into the uterus from four aspects: egg taking, fertilization, culture and transplantation.
1. Take eggs
The first step of IVF is to take eggs. Generally speaking, the process of egg retrieval requires the accumulation of enough follicles in the patient's ovary to ensure the successful acquisition of fertilized eggs. Drugs are usually used to stimulate ovarian development and mature follicles. Egg retrieval is usually carried out within 36 hours after the follicle matures. The fluid and eggs in the follicle are extracted by ultrasound guided fine needle puncture.
The process of egg retrieval generally requires local anesthesia, which is carried out through vaginal puncture. Before carrying out egg retrieval, the doctor will conduct pretreatment, including determining the appropriate time for egg retrieval and assisting in follicular development. The main purpose of this step is to obtain mature eggs and provide conditions for subsequent fertilization.
2. Fertilization
After taking the eggs, the eggs will be fertilized with sperm in vitro. Fertilization can be divided into conventional fertilization and single sperm injection (ICSI). Conventional fertilization is to cultivate eggs and sperm together in a culture dish, and they will combine to fertilize themselves. ICSI injects a single sperm into the egg to ensure the success rate of fertilization.
The fertilized eggs will continue to be cultivated to form fertilized eggs. The quality of fertilized eggs will be evaluated according to the cell division, and eligible embryos will be selected for transplantation preparation.
3. Cultivation
The fertilized eggs will be cultured in a Petri dish, usually in a constant temperature incubator suitable for cell growth. The culture process of the fertilized egg can last for several days, and the doctor will decide the best time for transplantation according to the quality and development of the embryo.
During the culture process, doctors will regularly observe the cell division of the embryo, and evaluate and select the quality of the embryo. At the same time, they will also monitor the development of the embryo to ensure that the embryo grows and develops normally in the culture dish.
4. Transplantation
Transplantation is the last step for IVF to be put into the uterus. During transplantation, doctors will use soft catheters or thin tubes to carefully place the cultured embryos into the patient's uterus. Transplantation operations usually do not require general anesthesia, but may require some local anesthesia or sedatives.
During transplantation surgery, doctors usually rely on ultrasound guidance to accurately place embryos in the uterus. The placement position will depend on the morphology and anatomy of the patient's uterus. Successful transplantation will increase the probability of successful pregnancy.
summary
The procedure of putting IVF into the uterus can be divided into four stages: egg taking, fertilization, culture and transplantation. The mature eggs are obtained by drug stimulation and fine needle puncture. The fertilization is carried out by conventional fertilization or ICSI technology. The culture will be carried out for several days to observe the quality and development of the embryo. Finally, the embryo will be accurately placed in the patient's uterus during the transfer operation.
The above steps are the main steps for IVF to be put into the uterus. This process requires careful operation and clinical experience of doctors, as well as close cooperation and emotional regulation of patients. The different links of these steps are critical, and close communication and cooperation between doctors and patients are needed to improve the success rate and realize the healthy birth of IVF.
