Specific operation steps of IVF

Test tube baby (IVF) is a method to help couples who cannot conceive naturally to achieve fertility through assisted reproductive technology. The success of this technology depends on the operation effect of the whole IVF step. The specific operation steps of IVF and the importance of each step will be introduced in detail below.

1. Maternity preparation

The first step is to prepare the puerpera. The puerpera need a detailed physical examination, including endometrial thickness, ovarian function, hormone levels and other aspects of detection. These inspection results will provide important reference for subsequent operations. At the same time, the puerpera need to inject ovulation promoting drugs to stimulate ovarian development, promote multiple follicles to mature and be collected. Next, through ultrasound guided follicular puncture technology, doctors will collect follicular fluid from the ovary and combine the collected eggs with the sperm of the spouse or donor. The first step is to ensure that the maternal health is good, the endometrium is suitable for implantation, and the ovary can produce enough healthy eggs, thus improving the success rate of pregnancy.

2. Fertilization and culture

The collected eggs and sperm are fertilized in vitro in the laboratory. This step can use the traditional in vitro fertilization (IVF) method, that is, sperm is added to the culture dish to naturally fertilize the egg, or assisted fertilization technology (ICSI) is selected, that is, a sperm is injected into the egg. After successful fertilization, the embryo will be cultured in a specific medium in the laboratory. Culture conditions need to control temperature, humidity, oxygen concentration and other factors to simulate the intrauterine environment as much as possible and promote embryonic development. The importance of this step is to ensure that the egg and sperm can successfully combine to produce healthy embryos and prepare for embryo implantation into the uterus.

3. Embryo implantation

After two to six days of embryo culture, the doctor will select one or more embryos with the most potential to be implanted into the uterus of the mother. This operation is usually performed by laparoscopy or catheter, and the specific method depends on the guidance of different hospitals and doctors. The number of embryos implanted is usually one or two, depending on the doctor and the couple. After embryo implantation, the pregnant women need to take some rest and precautions to avoid strenuous activities, so as to improve the probability of embryo implantation. The importance lies in ensuring the successful implantation of healthy embryos and creating favorable conditions for the successful implantation of embryos.

4. Follow up treatment after embryo implantation

After about two weeks, the mother can conduct blood or urine tests to confirm whether the pregnancy is successful. If the pregnancy is successful, the mother needs to start receiving continuous pregnancy care and monitoring, and carry out appropriate hormone support treatment according to the doctor's recommendations to help the embryo continue implantation and development. The importance of this step is to monitor the pregnancy situation in time, provide necessary support and treatment, and ensure the healthy development of the embryo and the final smooth delivery.

summary

As an assisted reproductive technology, IVF has achieved the reproductive aspirations of couples who cannot conceive naturally through a number of specific steps. Maternal preparation, fertilization and culture of eggs and sperm, implantation of embryos and subsequent treatment after embryo implantation are all crucial links in the whole process. The successful implementation of these steps is directly related to the success rate of IVF pregnancy. Doctors and pregnant women need to cooperate closely and cooperate with each other throughout the process to ensure that each step is carried out accurately, so as to improve the success rate of IVF.
