New Development of IVF Technology
IVF is a kind of assisted reproductive technology, which has made many new achievements. This article will elaborate on the new development of IVF technology from four aspects: embryo screening, embryo transfer technology, frozen egg technology and incubation technology.
Embryo screening technology
Embryo screening plays a key role in IVF technology. The latest development is the progress of gene diagnosis technology, including PGD (low complexity gene screening), PGS (high complexity gene screening) and PGT (pre implantation gene screening). More and more hospitals and laboratories begin to use these technologies to detect whether embryos carry genetic diseases, chromosome abnormalities or other gene mutations. This screening technology can not only help doctors select the healthiest embryos for transplantation, but also avoid passing on genetic diseases to the next generation.
The progress of embryo screening technology also includes the detection of single gene genetic diseases, such as non-invasive gene detection of blastocysts (NIPT) and genetic diagnosis before embryo implantation (PGD). These technologies can accurately detect whether the embryo carries specific gene mutations by analyzing the cells or DNA of the obtained embryo, thus helping couples prevent or treat certain genetic diseases.
In addition to the progress of gene diagnosis technology, another new development of embryo screening technology is non-invasive embryo assessment (NIA), which uses microradiography to detect the morphological and physiological characteristics of embryos. This technique does not need to invade embryos and can provide important information about embryo quality and development potential.
Embryo transfer technology
Embryo transfer is one of the key steps in IVF pregnancy. In recent years, doctors have adopted some innovative embryo transfer technologies to improve the success rate of IVF.
One of the new technologies is single embryo transfer (SET). The previous habit was to transplant multiple embryos in each IVF cycle to increase the chance of pregnancy. However, multiple embryo transfer also increases the risk of multiple pregnancy. The development of SET technology allows doctors to choose to transplant only one embryo in each cycle, thus reducing the risk of multiple pregnancies and improving the success rate of IVF.
Another new technology is embryo transfer (GIFT). GIFT is a technique for placing embryos directly into the uterine cavity, rather than cultivating embryos in the laboratory first. This technology can improve the adaptability of the embryo to the implantation environment and increase the possibility of pregnancy.
In addition, some auxiliary technologies are also widely used, such as frozen embryo transfer and the use of embryo adhesive. Through frozen embryo transfer, embryos can be implanted at an appropriate time, thus improving the success rate. Embryo adhesive is a substance coated on the endometrium, which can improve the success rate of embryo implantation.
Frozen egg technique
Frozen egg technology is a method of freezing female eggs for future use in IVF. The new development of this technology is the progress of ovarian protection technology.
Traditional frozen egg technology may cause damage to ovarian tissue, thus reducing the possibility of successful pregnancy. Current ovarian protection techniques include new egg freezing protocols and improvements in follicle stimulating agents. The new frozen egg scheme can reduce the damage of frozen eggs to ovarian tissue and improve the success rate of egg storage and pregnancy. At the same time, the improved follicle stimulating agent can better control the follicular development and reduce the side effects on the ovary.
Incubation technology
Incubation technology is one of the key steps in IVF technology, which involves cultivating and hatching the fertilized eggs to the appropriate development stage, and then transplanting them. In recent years, incubation technology has also made some new developments.
One of the new technologies is continuous culture system (CCS), which can continuously monitor the growth of embryos and provide more accurate development information to help doctors choose the best time for embryo transfer. This technique reduces the number of embryo interventions and improves the success rate of embryo transfer.
Another new technology is the Dynamic Incubation System (DIS), which simulates the development of embryos in the womb in the natural environment. DIS system dynamically adjusts the culture conditions according to the morphological and physiological characteristics of embryos to provide a more suitable environment for embryo development, thus increasing the possibility of pregnancy.
summary
IVF technology has made new progress in embryo screening, embryo transfer, frozen eggs and incubation technology. These technological advances not only improve the success rate of IVF, but also provide more choices for couples to choose the healthiest embryos and increase the possibility of pregnancy. With the continuous innovation and progress of technology, the prospect of IVF technology will become broader.
