Embryo screening method of test tube baby
IVF technology is an advanced assisted reproductive technology, which can help couples who cannot conceive naturally realize their reproductive dreams. In IVF technology, embryo screening is an important link, which allows women to select embryos that meet their expectations for implantation. The following is an introduction to the embryo screening methods available to women.
1. Gene diagnosis and screening
Gene diagnostic screening is a common method of embryo screening, which can help detect whether embryos carry certain genetic diseases. This screening method is usually carried out in the Human Genetic Disease Testing Center. First, doctors will collect samples from embryonic cells, and then analyze the embryos through gene sequencing technology. Through this screening method, women can know whether the embryo carries genetic diseases, and then decide whether to choose the embryo for implantation.
The advantage of genetic diagnosis screening is that it can help couples avoid passing on genetic diseases to the next generation, thus ensuring the health of offspring. At present, many hospitals provide genetic diagnosis and screening services, such as the Genetic Disease Testing Center of Peking Union Medical College Hospital and the Genetic Disease Screening Center of the Pediatric Hospital affiliated to Fudan University in Shanghai.
2. Gender screening
Sex screening is one of the common embryo screening methods in IVF. Many couples want their children to have a specific gender, which can be achieved through gender screening. Sex screening is mainly achieved through genetic sex identification of embryos. This screening method is usually carried out in specific reproductive medical centers, such as Shanghai Huashan Hospital Reproductive Center, Guangzhou Nanfang Hospital Reproductive Center, etc.
Gender screening may be restricted by laws in some countries and regions, so women need to understand local laws and regulations when conducting gender screening.
3. Chromosome screening
Chromosome screening is an important method for embryo screening, which is used to detect whether there are chromosome abnormalities in embryos. Chromosome abnormality is one of the common causes of abnormal embryonic development and abortion. Through chromosome screening, women can choose embryos with normal chromosomes for implantation to improve the success rate of IVF.
Chromosome screening is usually carried out by amniocentesis or chorionic biopsy. This screening method needs to be carried out in corresponding medical institutions, such as Shanghai Maternal and Child Health Hospital, Guangzhou Armed Police General Hospital, etc.
4. Genetic disease screening
In addition to genetic diagnosis screening, genetic disease screening can also be carried out during IVF. Genetic disease screening is mainly used to detect whether embryos carry specific genetic diseases. This screening method usually determines whether the embryo carries genetic diseases by detecting the genetic material in the embryo cell. Some genetic disease screening centers, such as the Genetic Disease Screening Center of Peking University Third Hospital and the Genetic Disease Screening Center of Shanghai Huashan Hospital, provide such screening services.
Screening for genetic diseases helps women decide whether to choose embryos carrying genetic diseases for implantation, thus reducing the risk of having children.
summary
Through gene diagnosis screening, sex screening, chromosome screening, genetic disease screening and other methods, women have a variety of options for embryo screening in the process of IVF. These screening methods can select the desired embryos for implantation according to individual needs, thus increasing the success rate of IVF and reducing the risk of genetic diseases and chromosomal abnormalities. However, when conducting embryo screening, women should understand local laws and regulations and abide by ethical norms.
