What is the principle of non-invasive IVF technology?
Non invasive IVF technology is a kind of assisted reproductive technology, which is widely used in the treatment of infertility. This technology aims to help couples who cannot conceive naturally realize their desire to have children. In the following four aspects, we will elaborate on the principle of non-invasive IVF technology.
1. In vitro fertilization
In vitro fertilization is the basic step of non-invasive IVF technology. First, women receive superovulation therapy to promote the development of multiple follicles. Then, after regular ultrasound examination and blood hormone monitoring, doctors determine the best time for fertilization. Next, the eggs are extracted through painless puncture and fertilized in vitro with their partner's sperm in a culture dish. After several days of in vitro culture, select the best quality embryos and transfer them back to the female uterus.
The success of IVF technology requires precise control of time and operation skills. Doctors and laboratory technicians need to strictly follow the operating procedures, while ensuring the pairing of fresh, high-quality sperm and eggs.
2. Embryo culture and selection
The fertilized eggs need to be cultured and selected in the laboratory before being transplanted back to the uterus. The culture conditions must meet the needs of embryo growth. At this stage, doctors usually use continuous or dynamic cultivation systems to provide a more stable and optimized cultivation environment.
Embryo quality assessment is a key link. Doctors will observe the cell division, cell symmetry, cytoplasmic content, embryo membrane pH and other indicators of the embryo to determine the best embryo. Some hospitals also use gene detection technology to carry out precise genetic screening of embryos, so as to select embryos without genetic disease genes for transplantation and improve the success rate.
3. Transplantation and pregnancy
After embryo culture and selection, doctors will select the best embryos for transplantation. This process is usually painless, and doctors use soft tubes to place the embryo in the most suitable position in the endometrium.
After transplantation, women need to receive hormone therapy such as progesterone to stabilize the endometrial environment and help embryo implantation. In 10-14 days after transplantation, the doctor will test the progesterone to confirm whether the pregnancy is successful.
4. Monitoring and pregnancy maintenance
Once pregnancy is confirmed, women need to conduct regular pregnancy monitoring. Doctors regularly check the development of the fetus and the health of the mother. If necessary, the doctor will carry out ultrasonic examination, blood test, etc. to ensure the smooth progress of pregnancy. In addition, women may receive some adjuvant treatment to maintain pregnancy, such as supplementary nutrition, anticoagulant treatment, etc.
Through the above steps, the non-invasive IVF technology provides an ideal assisted reproductive mode for infertile patients. Although the application of technology is subject to some restrictions and risks, it gives those couples who once had little hope hope to have children. Non invasive IVF technology has been widely used in many hospitals and reproductive medical centers
In conclusion, the principle of non-invasive IVF technology mainly includes in vitro fertilization, embryo culture and selection, transplantation and pregnancy, as well as monitoring and pregnancy maintenance. This technology provides a comprehensive and accurate method to control the reproductive process by simulating the human reproductive process in the laboratory, so that patients can have more opportunities to achieve their reproductive aspirations.
