Principle of Kato IVF technology
Kato IVF technology, also known as in vitro fertilization and embryo transfer technology, is a kind of medical assisted reproduction technology, which is a method to help infertile couples achieve their reproductive aspirations through artificial means. The principle of IVF technology mainly involves the following aspects:
1. In vitro fertilization
In vitro fertilization is one of the key steps in IVF technology. This process is usually divided into the following steps: hormone therapy, ovarian stimulation, egg collection, sperm collection, sperm and egg in vitro fertilization and embryo culture.
First, women need hormone therapy to promote ovarian development and produce multiple follicles. Then, after the follicle develops to the proper size, the follicle is extracted and the eggs are collected by a simple surgical method. At the same time, men provide sperm, and then put it together with eggs in a culture dish for in vitro fertilization. After successful fertilization, the embryo will continue to develop in the culture dish.
2. Embryo culture
After successful fertilization, the embryo needs to continue to develop in the culture dish. Embryo culture usually needs to simulate the internal environment and provide appropriate nutrition and growth conditions. This process involves the control of temperature, light, oxygen content and the formulation of the culture medium. Modern technology enables embryo culture to better simulate the human environment, thereby improving the survival rate and quality of embryos.
Embryos usually need to be cultured for 2 to 6 days, and can be transferred after reaching a certain development stage.
3. Embryo transfer
After the embryo has been cultured to a suitable stage of development, it can be transplanted back into the female uterus. This process is usually performed through the vagina and the embryo is carefully placed into the endometrium using a catheter. Embryo transfer is usually carried out within 2 to 6 days after ovarian stimulation and egg collection in women.
After transplantation, women usually need further hormone therapy to promote embryo implantation and pregnancy maintenance.
4. Follow up observation and pregnancy
After embryo transfer, it is necessary to further observe whether the embryo is successfully implanted and whether pregnancy occurs. Within a few weeks after transplantation, women can conduct blood or urine tests to determine whether pregnancy has occurred. Later, more detailed examination and observation, such as ultrasonic examination, are needed to determine whether the pregnancy is normal and the embryo is well developed.
If the pregnancy is confirmed to be successful, women need to continue to conduct pregnancy monitoring, including regular prenatal examination and disease prevention during pregnancy. If the pregnancy fails, it is usually necessary to restart the whole IVF process.
summary
The principle of Kato IVF technology involves in vitro fertilization, embryo culture, embryo transfer, and subsequent observation and pregnancy. Hormone therapy is used to promote ovarian development and collect eggs, while sperm is collected for in vitro fertilization. After successful fertilization, the embryo continues to develop in the culture dish. After the embryo has been cultured to a certain stage, it can be transplanted back into the female uterus. After transplantation, women need to receive pregnancy confirmation, follow-up observation and pregnancy monitoring. Kato IVF technology provides a choice for couples who cannot conceive naturally to realize their reproductive aspirations.
