Does the baby of three generations of IVF have genetic advantages?
With the continuous progress of science and technology and the development of biomedical field, IVF technology has gradually become an option for infertile couples to achieve their reproductive aspirations. While the traditional IVF technology can only combine sperm and eggs through in vitro fertilization, the current three generation IVF technology can go further. Through the combination of sperm, eggs and nuclei, babies have better genetic advantages. This article will elaborate on whether the three generation IVF babies have genetic advantages from four aspects.
One aspect: screening of genetic diseases
First, the third-generation IVF technology can screen genetic diseases. During the development of a fertilized egg, scientists can determine whether there is a risk of some abnormal genes and genetic diseases by detecting the genetic material in the fertilized egg. Once abnormalities are found, you can choose to transplant the normal fertilized eggs back to the mother to reduce the possibility of the baby suffering from genetic diseases.
Secondly, the third-generation IVF technology can also screen for gene mutations. Gene mutation is the root of some diseases, which may lead to a series of problems in the growth and development of babies. Through the three generation IVF technology, gene mutation screening can be carried out at the early stage of the fertilized egg, so as to avoid transplanting the fertilized egg with mutation gene back to the mother and improve the health level of the baby.
In addition, the third-generation IVF technology can also detect the carriers of recessive genetic diseases. Recessive genetic disease means that the patient needs to be transmitted by both families at the same time. If the two carriers give birth, the baby may get sick. By screening carriers and selecting fertilized eggs with normal genes for transplantation, the risk of baby disease can be reduced.
Aspect 2: Selection of high-quality eggs
The third generation IVF technology can also select high-quality eggs by screening eggs. The quality of eggs has an important impact on the development of embryos and the health of babies. Using the third-generation IVF technology, scientists can select healthy eggs with normal chromosomes for fertilization and transplantation by detecting the number and structure of chromosomes in eggs, reduce the risk of embryo termination and fetal abnormal development caused by chromosome abnormalities, and improve the genetic advantage of the baby.
Aspect 3: Selection of high-quality sperm
The third generation IVF technology can also screen sperm and select high-quality sperm. The quality of sperm and the stability of genetic material directly affect the genetic advantage of the baby. Through the three generation IVF technology, we can select healthy sperm for fertilization by detecting the genetic material and DNA integrity of sperm, reduce the risk of sperm DNA damage and mutation, and improve the genetic advantage of the baby.
Aspect 4: Selection of eugenic embryos
The third generation IVF technology can also select eugenic embryos by evaluating the quality of embryos. The selection of embryos entering the uterus is an important part of the third generation IVF technology. By evaluating the development degree, morphology, chromosome number, structure and other indicators of the embryo, scientists can select high-quality embryos for transplantation, improve the success rate of embryo implantation and development, and thus improve the genetic advantage of the baby.
In conclusion, through screening of genetic diseases, selection of high-quality eggs and sperm, and selection of eugenic embryos, the three generation IVF babies have high genetic advantages. The emergence of this technology provides better fertility choices for infertile couples and helps them achieve their fertility aspirations.
