What genetic diseases can test tube babies prevent in the United States?
IVF technology is an advanced reproductive medicine technology, which can help many infertile couples realize their reproductive dreams. In addition to solving the problem of infertility, IVF can also prevent some genetic diseases to a certain extent. In the United States, IVF technology has made positive achievements in preventing genetic diseases.
1. Treatment of Niemann Pick disease with ineffective antibiotics
Nieman Pick Disease is a rare disorder of genetic metabolism. The cells of patients cannot metabolize lipids normally. In some reproductive medical centers in the United States, doctors can carry out genetic testing at the early stage of embryonic development through IVF technology to screen out embryos without Niemann Pick disease gene for transplantation. This allows couples carrying the Niemann Pick disease gene in the family to choose genetically healthy embryos to avoid the risk of Niemann Pick disease for the next generation.
In addition, some hospitals in the United States have also tried to use ineffective antibiotics to treat babies born with Niemann Pick disease, so as to slow down the disease and improve the quality of life of children.
2. Screening out embryos carrying cystic fibrosis gene for embryo transfer
Cystic fibrosis is a common hereditary disease, which mainly affects the respiratory system, digestive system and reproductive system. Through IVF technology, doctors can conduct gene screening for embryos at the early stage of embryonic development to exclude embryos carrying cystic fibrosis genes. This screening process helps prevent the genetic transmission of the disease.
Some reproductive medical centers in the United States, such as Boston Children's Hospital and Los Angeles Children's Hospital, carry out embryonic gene screening in the process of IVF to screen out embryos carrying cystic fibrosis genes for embryo transfer, so as to reduce the transmission risk of cystic fibrosis in the next generation.
3. Screening of embryos carrying hemophilia gene
Hemophilia is a common hereditary disease, and patients are prone to bleeding due to lack of coagulation factors. In vitro baby technology can conduct gene screening for embryos at the early stage of embryo development to exclude embryos carrying hemophilia gene. In the United States, some famous reproductive medicine centers, such as the Presbyterian Hospital in New York and the Reproductive Health Center of the University of California, San Francisco, have successfully used IVF technology to prevent the genetic transmission of hemophilia.
4. Screening of embryos carrying Down syndrome gene
Down syndrome is a common chromosomal disorder, which is usually accompanied by mental retardation and other physical characteristics. With IVF technology, doctors can conduct chromosome screening on embryos at the early stage of embryonic development to exclude embryos carrying Down syndrome genes.
Some reproductive medical centers in the United States, such as Johns Hopkins Hospital, conduct chromosome screening in the process of IVF to identify whether there are abnormalities in Down syndrome genes. The application of this technology enables couples with Down syndrome gene to select embryos that are not diseased, thus avoiding passing the gene on to the next generation.
summary
In the United States, IVF technology has made significant progress in preventing genetic diseases. By carrying out gene screening at the early stage of embryonic development, embryos carrying genes of diseases such as Niemann Pick disease, cystic fibrosis, hemophilia and Down syndrome can be excluded, thus reducing the risk of transmission of these genetic diseases in the next generation. For those couples with a family history of genetic diseases, this has brought new hope and opportunities to their children.
