Can big S test tube babies have genetic diseases?
As an assisted reproductive technology, Big S is increasingly accepted and adopted by more couples. However, there are many doubts about whether large S IVF can cause genetic diseases. This article will discuss this problem and explore whether gene screening can solve related problems.
Existence of hereditary diseases
Hereditary disease refers to the disease caused by gene mutation, which can be inherited from parents to children. These diseases include cystic fibrosis, congenital heart disease, hereditary diabetes, etc. In the process of embryo transfer of large S IVF, if embryos with genetic diseases are selected, IVF may inherit these diseases.
However, through the research and technological progress of scientists, the risk of genetic diseases in large S IVF has been greatly reduced. At present, many hospitals carry out genetic disease screening before large S test tube babies to reduce the risk of disease.
Gene screening of large S test tube infants
The genetic screening of large S test tube infants is mainly carried out through embryonic chromosome screening and single gene genetic disease screening. Embryo chromosome screening can detect whether there are abnormal chromosomes in the embryo, such as Down syndrome, 50% Widenburg syndrome of the father, etc. Single gene genetic disease screening can detect specific single gene diseases, such as cystic fibrosis, spongiform dysplasia, etc.
Gene screening is mainly achieved through careful embryo culture and genetic analysis before IVF. In the early stage of embryonic development, scientists can collect embryonic cells for genetic analysis to determine whether there is a risk of genetic disease in the embryo.
Feasibility and limitation of gene screening
Although the genetic screening of large S test tube infants has greatly reduced the risk of genetic diseases, there are still some limitations.
First of all, gene screening can only detect known genetic diseases, and the screening ability for new gene mutations or rare diseases is limited. Secondly, because the embryo culture and genetic analysis technology of large S test tube babies are still not perfect, sometimes false positive and false negative situations occur, that is, the embryos are actually healthy, but are wrongly judged to carry disease risks or healthy embryos are wrongly judged to carry disease risks.
In addition, genetic screening cannot completely eliminate the risk of genetic diseases. Even if the screening results show that there is no risk of genetic disease in the embryo, it is still possible to mutate in the process of embryo transfer, leading to the existence of the risk of children's disease.
summary
Big S IVF has made remarkable progress in genetic disease screening. Embryonic chromosome screening and single gene genetic disease screening can greatly reduce the risk of genetic diseases. However, gene screening still has some limitations, which cannot completely eliminate the risk of genetic diseases. Therefore, for couples who want to avoid genetic diseases through large S IVF, they still need to understand the limitations of gene screening and make decisions under the guidance of doctors.
