New technology of IVF
IVF technology is a surrogate technology, which helps couples with fertility problems to realize their fertility dreams through IVF. In recent years, with the continuous development of technology, IVF technology has also been a lot of innovation and improvement. The following will introduce the new technology of IVF in detail from four aspects: gene screening, embryo culture, embryo selection and transfer technology.
Gene screening technology
Gene screening technology is an important innovation in the field of IVF. This technology identifies embryos that may carry genetic diseases through genome analysis of embryos. A commonly used gene screening technology is parental gene testing, which can predict the potential risk of genetic diseases and screen out embryos that do not carry these gene mutations by analyzing the genes of couples.
In addition, a technique called aneuploidy screening can detect whether there are chromosomal abnormalities in embryos. Chromosome abnormality is one of the common causes of pregnancy failure and embryo malformation. Aneuploidy screening technology can accurately determine whether there are chromosomal abnormalities in embryos through genome analysis of embryos, and help couples select healthy embryos for transplantation.
With the development of gene screening technology, many hospitals, such as California Reproductive Science Center in the United States and London Infant Clinic in the United Kingdom, are actively applying these technologies to help couples screen healthy embryos and improve the success rate of IVF.
Embryo culture technology
Embryo culture technology is the key link of IVF technology. The traditional IVF technology usually adopts a continuous culture system in the process of embryo culture. However, this system is not conducive to the development of embryos. To solve this problem, scientists have developed an embryo culture technology called time sharing system.
The time sharing system divides the petri dish into different areas, each of which has different culture conditions, so that the embryo can choose the appropriate culture environment according to its own needs. This technology can better simulate the natural uterine environment and improve the survival rate and quality of embryos.
For example, the Melbourne IVF Clinic in Australia took the lead in introducing the time sharing system and achieved remarkable results in the process of embryo culture.
Embryo selection technology
Embryo selection technology is an important innovation in IVF technology. Traditional IVF technology is usually selected by doctors according to the appearance of the embryo in the process of embryo selection. However, appearance cannot fully reflect the quality of embryos and the potential risk of genetic diseases.
In order to improve the accuracy of embryo selection, scientists have developed a technology called whole genome sequence detection. This technology can conduct a comprehensive analysis of the embryo genome, and identify possible genetic disease risks and chromosomal abnormalities. Through whole genome sequence detection, couples can more accurately select healthy embryos for transplantation, and improve the success rate of IVF.
The whole genome sequence detection technology has been applied in many hospitals, such as California Test Tube Baby Center in the United States, Beijing Maternity Hospital in China, etc.
Embryo transfer technology
Embryo transfer technology is the last step of IVF technology. In traditional IVF technology, doctors usually transfer multiple embryos at the same time to increase the chance of pregnancy. However, with the innovation of transfer technology, single embryo transfer technology is gradually emerging.
Single embryo transfer technology can reduce the risk of multiple pregnancy by selecting the best embryo for transfer. At the same time, this technology can also reduce fertility risks and improve the success rate of IVF. Many internationally renowned hospitals, such as Karolinska College in Sweden and Medical College of University of Toronto in Canada, have adopted single embryo transfer technology in clinical practice.
Summary
The new technology of IVF covers gene screening, embryo culture, embryo selection and transfer technology. Gene screening technology helps couples choose healthy embryos through genome analysis of embryos. Embryo culture technology simulates the natural uterine environment through a time sharing system to improve the survival rate and quality of embryos. Embryo selection technology improves the accuracy of embryo selection by detecting the whole genome sequence. The single embryo transfer technology in embryo transfer technology reduces the risk of multiple pregnancies and improves the success rate of test tube babies. The application of these new technologies makes the IVF technology more accurate and safe, and brings more hope to couples with fertility problems.
