Importance of selecting high-quality embryos in IVF hospitals
IVF technology is a medical means to help couples who cannot conceive naturally to achieve their reproductive aspirations. The improvement of the success rate depends on the selection of high-quality embryos. Therefore, how to select high-quality embryos is crucial in IVF hospitals. Next, we will discuss how to select high-quality embryos from four aspects: embryo quality assessment, gene screening, embryo freezing and incubation technology.
Embryo quality assessment
Embryo quality is an important indicator of embryo development potential, which directly affects the success rate. In IVF hospitals, common embryo quality assessment methods include appearance assessment and cytological assessment. Appearance evaluation mainly evaluates the quality of embryos by observing the morphology, symmetry, number of cells and other indicators of embryos under a microscope. Cytological assessment assesses the quality of the embryo by detecting the chromosome number and cell morphology of the cells in the embryo. Through these evaluation methods, IVF hospitals select embryos with good development potential for transplantation, so as to improve the success rate.
Generally speaking, embryo evaluation can be classified according to the level of embryos, such as top-level, primary, secondary, etc. The top embryo is usually regular in shape, symmetrical, and has normal cell number, which is the most ideal choice. The primary and secondary embryos may have some morphological problems, but still have good development potential. The IVF hospital will comprehensively consider which embryo to transplant according to the specific situation of the couple and the quality of the embryo.
Gene screening
With the progress of modern medicine, gene screening technology is widely used in IVF hospitals, which can help doctors select embryos with low risk of genetic diseases. Gene screening is mainly used to detect the chromosome number of embryos and the presence or absence of genetic disease genes to screen embryos with chromosome abnormalities or genetic diseases.
Common gene screening techniques include carrier screening and parental single gene disease screening. Carrier screening mainly tests whether parents carry disease genes, and reduces the risk of disease by avoiding embryo transfer with genetic diseases. Parental single gene disease screening aims at known single gene genetic diseases, and uses specific technology to screen whether embryos carry pathogenic genes. Through gene screening, IVF hospitals can avoid passing on genetic diseases to the next generation and improve the health quality of infants.
Embryo freezing and incubation technology
Embryo freezing technology is a commonly used method to preserve embryos in IVF hospitals. This technology can freeze the surplus embryos for future use. Through embryo freezing, IVF hospitals can improve the utilization rate of embryos and reduce the risk of multiple pregnancy.
At the same time, incubation technology is also an important means to select high-quality embryos. Traditional incubation technology needs to take out embryos for inspection and evaluation for many times, while modern incubation technology can continuously observe the development of embryos without disturbing the growth process of embryos. This technique can better evaluate the developmental ability of embryos, so as to select embryos with high developmental potential.
Summary
Selection of high-quality embryos is crucial to the success rate of IVF. IVF hospitals select high-quality embryos by means of embryo quality assessment, gene screening, embryo freezing and incubation technology. Embryo quality assessment mainly determines the quality of embryos through appearance and cytological assessment. Gene screening can exclude embryos carrying genetic diseases and reduce the risk of disease. Embryo freezing and hatching technology can improve the utilization rate of embryos and evaluate the development ability of embryos. To sum up, selecting high-quality embryos is the key measure to improve the success rate of IVF hospitals.
