Improvement of IVF technology
IVF technology refers to the method to help couples who cannot conceive naturally to achieve fertility through assisted reproductive technology. With the continuous progress of science and technology and the continuous development of medical technology, IVF technology is also constantly improving. The improvement of IVF technology is described in detail from four aspects.
1. Improvement of egg retrieval technology
Fetching eggs is one of the key steps in IVF technology, which determines the quality and health of subsequent embryos. The improvement of egg retrieval technology is mainly shown in the following aspects.
First of all, modern assisted reproductive technology can improve the accuracy of egg retrieval through ultrasound guided ovarian puncture. Doctors can observe the position and size of the ovary through ultrasound, so as to carry out accurate puncture, minimize damage and improve the effect of egg retrieval.
Secondly, the drugs used in the egg retrieval process have also been improved. Modern medical technology makes the choice of drugs for ovum retrieval more individualized, and it can be finely adjusted according to women's age, ovarian reserve and other factors. This will help to improve the quality and quantity of egg retrieval and increase the probability of success of IVF.
Finally, the embryos after egg retrieval can be screened by PGD/PGS. PGD (single gene genetic disease pre implantation genetic diagnosis) and PGS (polychromosome abnormality and gene mutation screening) are technologies for gene detection of embryos. Through screening, doctors can choose healthy embryos to be implanted into the uterus to reduce the occurrence of diseases caused by bad gene inheritance.
2. Improvement of embryo culture technology
Embryo culture technology is another key link in IVF technology, which directly affects the quality and survival rate of embryos. The improvement of embryo culture technology is mainly shown in the following aspects.
First, the formula of embryo culture medium has been improved. Modern embryo culture media can provide more complete nutrition and support, which is conducive to early embryonic development and cell division, and improves embryo quality and survival rate.
Secondly, continuous culture can better simulate the uterine environment. The traditional embryo culture is carried out in a culture dish, while the continuous culture is to put the embryo in the incubator to simulate the stable environment in the uterus, which is more conducive to the development of the embryo.
Finally, the improvement of embryo culture technology is also reflected in the extension of culture time. In the past, embryos were implanted into the uterus after being cultured in petri dishes for a short time, but now the culture time of embryos can be extended to 5 or 6 days. By doing so, we can screen out healthier and better developed embryos and improve the probability of success of IVF.
3. Improvement of frozen embryo technology
Frozen embryo technology is to freeze the surplus embryos for future use after in vitro fertilization. The improvement of frozen embryo technology is mainly reflected in the following aspects.
First of all, modern frozen embryo technology uses more professional freezing liquid, which can better protect embryos. The special protective agent added to the freezing solution can reduce the damage of freezing to embryos and improve the survival rate of embryos.
Secondly, the freezing rate of frozen embryo technology has been improved. Rapid freezing technology can effectively prevent the formation of ice crystals in embryos, reduce the damage to cells, and improve the quality and survival rate of frozen embryos.
Finally, the thawing technology of frozen embryo technology has also been improved. Modern medicine can quickly thaw and restore frozen embryos to normal state through special thawing procedures to ensure their ability to develop and implant into the uterus.
4. Improvement of embryo implantation technology
Embryo implantation technology is the last step of IVF technology, which determines whether the embryo can be successfully implanted and developed. The improvement of embryo implantation technology is mainly shown in the following aspects.
First, modern embryo implantation technology can improve the accuracy of implantation through ultrasound guided uterine cavity puncture. Doctors can observe the position of uterine cavity and embryo in real time through ultrasound, so as to accurately implant the embryo into the uterus and improve the success rate of implantation.
Secondly, the improvement of embryo implantation technology also includes the use of catheter implantation, fixed embryo position and other methods. These methods can better protect embryos and improve the success rate of implantation.
Finally, embryo implantation technology is combined with the application of adjuvant treatment methods, such as progesterone and other drugs. These adjuvant treatments can improve the quality and stability of endometrium and increase the implantation rate of embryos.
Summary
With the continuous progress of science and technology and the continuous development of medical technology, IVF technology has been continuously improved in egg retrieval technology, embryo culture technology, frozen embryo technology and embryo implantation technology. These improvements make IVF technology more accurate, safe and more successful. In the future, with the further development and optimization of technology, IVF technology is expected to achieve breakthroughs in more aspects, bringing more hope for couples who cannot conceive naturally.
