Steps and key links of IVF

As an assisted reproductive method, IVF technology has become an important way for many couples who cannot conceive naturally to achieve their reproductive aspirations. The key to the success of IVF lies in the implementation of each step and the control of key links. Next, we will elaborate on the steps and key links of IVF from four aspects.

1. Ovulation promotion stage

The ovulation induction stage is the key first step of IVF. On the basis of leading follicular growth and ovulation in normal cycles, drugs are used to promote the growth of ovarian polycystic follicles and improve the number and quality of ovulation kilns. The use and dosage of ovulation promoting drugs and the method of monitoring follicle growth all need to be precisely regulated and monitored to avoid excessive stimulation or premature termination before ovulation, and to ensure the optimal state of egg quality and quantity. In ovulation promoting hospitals, ultrasound monitoring technology is generally used to observe the growth of follicles. The doctor will conduct regular ultrasound examination to determine the number and size of follicles and master the rhythm of follicle growth. When the size of the follicle meets the requirements, the doctor will usually recommend injection of ovulation promoting drugs to guide the ovulation of the follicle, so as to ensure the best time to take eggs.

2. Egg collection stage

The egg collection stage is another key link in the IVF process. Usually, when the follicle grows to a certain size, under the guidance of B-ultrasound, doctors will use a fine needle puncture to probe into the female ovary and suck out the follicular fluid. This process requires the use of local anesthesia to relieve pain. Follicular fluid was sent to the laboratory for centrifugation, and the separated eggs were identified and classified under the microscope, and merged with the prepared sperm. The key to the egg collection stage is the doctor's operating experience and technical level, as well as the high quality of equipment and the implementation of health standards, to ensure the quantity and quality of eggs collected.

3. Fertilization and embryo culture stage

The stage of fertilization and embryo culture is one of the key links in the process of IVF. In the laboratory, eggs and sperm are artificially fertilized to produce fertilized eggs. The fertilized egg will be controlled by specific environment in the culture dish, including temperature, nutrient and oxygen content. The time of embryo culture is usually 3-5 days. During this period, doctors and laboratory staff will constantly observe the development of embryos and screen healthy embryos as candidates for transplantation. The key of embryo culture stage lies in the control of laboratory conditions and the quality of embryo culture. Strictly control the composition of the culture medium and the stability of the culture environment to maximize the success rate of embryonic development.

4. Embryo transfer and pregnancy detection stage

Embryo transfer and pregnancy detection are the last key links in the process of IVF. After embryo culture and screening, the doctor will put the selected embryo into the female uterus through a catheter. This process usually does not require anesthesia, and the number of embryos will be determined according to the quantity and quality of the cultured embryos. After embryo transfer, the patient needs a period of rest and observation. After the embryo implantation in vivo is successful, pregnancy test can be carried out to confirm whether the pregnancy is successful. The key to the pregnancy detection stage is the strict monitoring of doctors' techniques and measures to ensure the successful implantation of embryos and pregnancy.

Summary

The steps of IVF involve ovulation induction, egg collection, fertilization and embryo culture, embryo transfer and pregnancy detection. Each step has key execution details and link control, which requires precise operation of the hospital and high-quality management of the laboratory. Only when each link is properly handled and controlled can IVF technology achieve the desired effect and help couples who cannot conceive naturally realize their reproductive dreams.
