How to select suitable IVF babies through gene screening?
The development of IVF technology has enabled more and more couples to realize their dream of childbirth. In the process of IVF, it is very important to choose the right embryo, and gene screening technology can help couples choose the healthiest embryo. This article will elaborate on how to select suitable IVF through gene screening methods from the following aspects.
Principles of gene screening technology
Gene screening technology refers to screening healthy embryos by detecting their genes. At present, the commonly used gene screening technologies are PGD (embryonic gene diagnosis) and PGS (embryonic gene screening). PGD technology mainly detects whether embryos carry genetic diseases, while PGS technology can screen whether the chromosome number and structure of embryos are normal.
PGD technology usually takes a small part of cell tissues or embryonic blastocysts for gene detection to analyze whether the gene sequence of the embryo is abnormal. PGS technology requires taking a small number of cells for chromosome detection to determine whether the chromosome structure and number of embryos are normal. These techniques are carried out before IVF transplantation to ensure that the healthiest embryos are selected.
Application scope of gene screening
Gene screening technology is widely used, mainly in the following aspects:
First, genetic disease screening. Some common genetic diseases, such as thalassemia and cystic fibrosis, can be judged by gene screening technology, so as to avoid passing disease genes to the next generation.
Second, chromosome abnormality detection. Chromosome abnormality is one of the main reasons for low success rate and early abortion of IVF. PGS technology can screen embryos with abnormal chromosome number and structure, and improve the success rate of IVF transplantation.
Third, screening for age-related diseases. When women are over 35 years old and pregnant, the risk of chromosomal abnormalities and genetic diseases will be greatly increased. Through gene screening technology, we can determine whether the embryo carries abnormal genes, and help couples choose healthier embryos when they are older.
Medical institutions with gene screening technology
In China, many medical institutions have provided gene screening technology to help couples choose eugenics. For example, medical institutions such as Peking Union Medical College Hospital and Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine have set up special genetic counseling centers and test tube baby centers to provide gene screening services.
In these medical institutions, professional geneticists and doctors will develop gene screening programs according to the needs and specific conditions of couples, and help couples choose healthy embryos. At the same time, these medical institutions also provide consulting services to help couples understand the relevant content and risks of gene screening and help them make rational decisions.
summary
Selecting suitable IVF through gene screening technology can improve the success rate of IVF, reduce the transmission risk of genetic diseases, and help couples select the healthiest embryos. The principle of gene screening technology is clear and has a wide range of applications, and many medical institutions in China have already provided this service. Before choosing IVF, couples can consider selecting the most suitable embryo through gene screening to realize their fertility aspirations.
