New progress of IVF technology in the United States
In vitro fertilization and embryo transfer (IVF-ET) is a high-tech method to help infertile couples achieve their reproductive aspirations. With the continuous development of science and technology, IVF technology in the United States has also made many new progress. These progress will be described in detail from several aspects below.
1. Progress of pre implantation gene screening technology
IVF technology has made new progress in pre implantation gene screening in early pregnancy. Through genetic screening of fertilized eggs, embryos carrying some serious genetic diseases can be found and excluded as early as possible. This technique is called preimplantation genetic diagnosis (PGD) or preimplantation genetic screening (PGS). Some IVF hospitals in the United States have begun to use this technology to provide more professional gene screening services for couples.
The progress of pre implantation gene screening technology means that couples can better avoid common genetic diseases and chromosome abnormalities when selecting embryos, and improve embryo implantation rate and pregnancy success rate. At the same time, this technology also reduces the rate of embryo abortion caused by chromosome abnormalities, providing a higher success rate for infertile couples.
2. Improvement of frozen embryo technology
Frozen embryo technology is an important part of IVF technology. In recent years, IVF hospitals in the United States have made some improvements in frozen embryo technology. The traditional frozen embryo technology needs to use liquid nitrogen for cryopreservation, and requires professional equipment and technology to maintain the frozen state of embryos.
However, the new frozen embryo technology uses more advanced "fast freezing" or "ultra fast freezing" technology, which can better protect the integrity and survival rate of embryos. This technology reduces the cell damage of embryos during freezing and thawing, improves the survival rate of fertilized eggs, and is more convenient for couples to arrange. Some IVF hospitals in the United States have begun to apply this new frozen embryo technology, and achieved good results.
3. Improvement of embryo culture technology
The development of embryos in vitro culture medium is one of the key links in IVF technology. In recent years, the test tube baby technology in the United States has improved the success rate and quality of embryo development by improving embryo culture technology. The new medium formula and culture conditions make the development of embryos in vitro more close to the natural environment. In addition, some IVF hospitals in the United States have also introduced higher-level incubator and microscope technology to monitor the development of embryos.
The improvement of embryo culture technology has significantly improved the success rate of IVF and reduced the risk of abnormal embryonic development. When selecting embryos, couples can better select better quality embryos and improve the success rate of pregnancy.
4. Integrated application of assisted reproductive technology
In addition to traditional IVF technology, some IVF hospitals in the United States also integrate assisted reproductive technology and IVF technology to improve the success rate. For example, the ovarian stimulation and follicle monitoring techniques in assisted reproductive technology can better grasp the optimal fertilization time and improve the pregnancy rate and success rate.
Through the integrated application of assisted reproductive technology and IVF technology, some IVF specialist hospitals in the United States can provide more personalized treatment programs for different couples, improve the success rate of embryo transfer, and help more couples realize their dreams.
Summary
The IVF technology in the United States has made new progress in many aspects. The progress of pre implantation gene screening technology, the improvement of frozen embryo technology, the improvement of embryo culture technology and the integrated application of assisted reproductive technology have all provided better choices and higher success rates for infertile couples. The development of these technologies will further promote the development of IVF technology and bring good news to more couples who are eager to have children.
