The Latest Development of IVF Technology in the United States
As one of the leaders in IVF technology, the United States has made new progress. The latest progress of IVF technology in the United States will be described in detail from four aspects: embryo screening, embryo culture, embryo freezing and hormone therapy.
Embryo screening
Embryo screening is an important part of IVF technology, which aims to select healthy embryos and improve the success rate. In the latest progress, some American hospitals have adopted genome screening technology. The specific implementation method is to extract a small number of embryonic cells for genetic analysis to determine whether there is a single gene disease in the embryo. The application of this technology enables parents to choose embryos that do not carry specific genetic diseases, reducing the risk of birth defects.
In addition, the United States has also conducted a research called PGS (Preimplantation Genetic Screening) in embryo screening, which aims to screen embryos with the correct number of chromosomes and further improve the success rate of IVF. The application of this technology can reduce the risk of pregnancy failure due to chromosome abnormalities in the embryo.
Embryo culture
Embryo culture is another important part of IVF technology. It can increase the survival rate of embryos by providing a good culture environment. In recent years, some hospitals in the United States have begun to use time - sensitive microscope technology for embryo culture. This technology can provide more information about embryo quality by continuously recording images during embryo development. This non-invasive real-time monitoring technology helps to screen embryos with higher potential and improve the success rate.
In addition, some hospitals are also studying the use of auxiliary current to improve the embryo culture environment. The auxiliary current can simulate the uterine cavity environment in the mother during natural pregnancy, promote embryo development and improve embryo quality. The introduction of this technology will make the IVF technology closer to natural pregnancy.
embryo freeze
Embryo freezing is a common practice in IVF technology, which is used to preserve the remaining embryos or transfer frozen embryos. The latest development is that some hospitals in the United States have begun to adopt a new freezing technology, called rapid freezing. Compared with the traditional slow freezing technology, rapid freezing can better protect the integrity and survival rate of embryos. For IVF patients, this means that more frozen embryos can be successfully thawed and transferred, increasing the success rate and reducing the number of repeated egg retrieval.
In addition, in order to make better use of embryos, some American hospitals began to explore the use of natural cycle in the frozen embryo transfer cycle for control. This means that instead of using hormone drugs for control, embryos are transferred according to women's natural ovulation cycle. This method makes the IVF process less harmful to the body and reduces the side effects of drugs.
hormone therapy
Hormone therapy plays an important role in IVF technology, which is used to stimulate ovarian development and increase the number of follicles. In order to improve the effect of hormone therapy and reduce side effects, some hospitals in the United States have begun to adopt new individualized hormone therapy programs. According to the individual physiological characteristics and medical history of the patient, this program develops a targeted hormone treatment plan to make the treatment more accurate and effective.
In addition, in order to reduce the side effects of hormone therapy, some hospitals are also exploring new ways of hormone administration, such as the use of patches, nasal spray and other alternatives to traditional injection methods. These new ways of administration are more convenient and comfortable, not only reducing the pain of patients, but also improving the absorption efficiency of hormones.
summary
In the United States, IVF technology has made many recent advances in embryo screening, embryo culture, embryo freezing and hormone therapy. Healthy embryos can be selected through genome screening and PGS technology; The success rate of embryo culture was improved by auxiliary focusing microscope and auxiliary current technology; Rapid freezing technology and natural cycle embryo transfer reduce side effects; Individualized hormone treatment scheme and new drug administration mode improved the therapeutic effect. These advances make IVF technology more accurate, safe and successful.
