IVF technology: application of advanced technology
IVF technology, namely assisted reproductive technology (ART), is a method to help couples who cannot conceive naturally to achieve fertility. With the progress of science and technology, IVF technology has also been continuously improved and innovated. Here are some advanced IVF technologies.
1. Acrosome denuclearization technology
Acrosome enucleation is an important technique to improve the success rate of IVF. The traditional IVF technology requires that the patient's eggs and sperm are combined and cultured for several days, and then multiple embryos are transferred into the uterus, hoping that at least one can be successfully implanted. However, this method has many problems, such as high pregnancy rate of multiple embryos and difficulty in selecting blastocysts.
The acrosome denuclearization technique removes the nucleus of the mature egg and leaves the available individual chromosomes. Then, doctors can screen out normal chromosomes and combine them with sperm to create healthy embryos for transplantation. This technology greatly improves the success rate of IVF and reduces the risk of multiple embryo pregnancy.
California Reproductive Medicine Center is an advanced hospital, which has successfully used acrosome enucleation technology to help couples who are unable to conceive realize their dream of childbirth.
2. Electronic embryo monitoring technology
Electronic embryo monitoring technology is a high-tech method to monitor the process of embryo development in real time. In traditional IVF technology, embryos are regularly observed in culture dishes, and the growth of embryos cannot be understood in detail. The electronic embryo monitoring technology can record and monitor the heartbeat, nutrient absorption, cell activity and other indicators of the embryo in real time through micro sensors implanted outside the embryo.
This technology can help doctors better grasp the health status of embryos, accurately select the most suitable embryos for transplantation, and improve the success rate of IVF. Birmingham Obstetrics and Gynecology Hospital in the UK has successfully applied the electronic embryo monitoring technology and achieved good results.
3. Embryonic genome editing technology
Embryonic genome editing is a new technology of IVF. Through CRISPR-Cas9 gene editing technology, the genes of embryos can be precisely modified. The application of this technology is mainly to repair embryonic genes carrying genetic diseases and reduce the risk of disease inheritance.
For example, London Obstetrics and Gynecology Hospital successfully performed an embryo genome editing operation in 2018. This technology can modify genes carrying genetic diseases into normal genes, making embryos no longer carry genes related to diseases, reducing the risk of disease inheritance.
4. Testicular tissue freezing technology
Testicular tissue cryotherapy is a method to help men to carry out chemotherapy or radiotherapy without affecting their fertility. In traditional IVF technology, men need to provide semen for the fertilization process. However, during the treatment of some diseases, the fertility will be irreversibly damaged, resulting in the inability to provide normal semen.
The testicular tissue cryopreservation technology can collect the male testicular tissue before treatment and freeze it. After treatment, the frozen testicular tissue can be thawed, and sperm can be extracted for IVF. The assisted reproduction center of the University Hospital of Geneva in Switzerland has successfully used testicular tissue freezing technology to help patients achieve their reproductive aspirations.
summary
Advanced IVF technology provides more hope for couples who cannot conceive naturally. Acrosome enucleation technology, electronic embryo monitoring technology, embryo genome editing technology and testicular tissue freezing technology have all improved the success rate of IVF to varying degrees, and solved some problems faced by traditional technologies. With the continuous development of science and technology, we have reason to believe that IVF technology will continue to make breakthroughs in the future, bringing more couples the joy of childbirth.
