What technologies are available in IVF?
IVF refers to the process that fertilized eggs are cultured in vitro and developed to a certain stage through assisted reproductive technology, and then transplanted into the mother's body for further development. The whole process of IVF involves the application of many technologies, including in vitro fertilization (IVF), embryo culture, embryo screening and transfer. Through the combined use of these technologies, couples who cannot conceive naturally can realize their wishes of pregnancy and childbirth.
In vitro fertilization (IVF)
In vitro fertilization (IVF) is the core step and key link of IVF technology. It refers to the removal of eggs and sperm from their spouses or donors, in vitro fertilization and embryo culture in vitro, and then transfer the well developed embryos back to the mother.
First, in order to improve the success rate of IVF, women need to inject ovulation promoting drugs to promote the ovarian development of more follicles. After that, determine the maturity of follicles through ultrasonic monitoring, and then collect oocytes at an appropriate time. Next, the collected eggs and sperm were fertilized in vitro in a culture dish, and the embryonic development was observed 24-48 hours later.
In vitro fertilization technology also includes double embryo transfer and frozen embryo technology. Double embryo transfer refers to the simultaneous implantation of two embryos into the mother to increase the chances of successful implantation. The frozen embryo technology is to freeze unused embryos for the next transfer and improve the chance of pregnancy.
Embryo culture technology
Embryo culture technology is an important part of IVF technology. It means that the fertilized egg can normally develop to the embryonic stage by controlling the culture environment in vitro. Embryo culture needs to strictly control the composition, temperature, PH value and other factors of the culture medium to simulate the physiological environment in the mother.
The culture medium used in modern embryo culture technology includes basic culture medium, development promoter and auxiliary growth factor. The normal development of embryo morphology and development speed can be effectively promoted through different medium combinations and dosage adjustment.
The development of embryo culture technology also brings new challenges and opportunities. For example, technologies that enhance the accurate screening of embryos are also constantly evolving, such as gene detection. These techniques can be used to detect whether there are potential genetic defects in embryos, which will help reduce the occurrence of genetic diseases.
Embryo screening technology
The purpose of embryo screening technology is to improve the success rate of IVF and reduce the risk of embryo implantation failure. It refers to the evaluation of embryo quality through the detection of genetic information, chromosome structure, cell morphology and other indicators in the process of embryo culture.
Embryo screening technology mainly includes genetic screening and morphological screening. Genetic screening mainly uses PGS (Preimplantation Genetic Screening) technology to detect the chromosome structure and gene mutation of embryos. Morphological screening is to evaluate the development of embryos by observing their morphological performance in vitro.
Through embryo screening technology, high-quality embryos can be selected to be transferred back to the mother, improving the probability of successful implantation and reducing the risk of abortion. At the same time, it can also prevent the occurrence of genetic diseases and reduce the chance of conceiving children with problems.
Summary of IVF stage
The IVF stage involves many key technologies, including in vitro fertilization, embryo culture, embryo screening, etc. In vitro fertilization technology is the core link of the whole process. The application of culture medium can make the fertilized egg develop normally. The emergence of embryo screening technology has further improved the success rate and reduced the occurrence of genetic diseases. Through the integrated application of these technologies, IVF technology is gradually becoming the hope of couples who cannot conceive naturally+
