How to develop the medical technology of IVF
As an important part of assisted reproductive technology, IVF technology aims to help couples who cannot conceive naturally realize their reproductive dreams. In recent years, with the continuous development of medical technology, IVF technology has also made considerable progress. This article will elaborate on how to develop the medical technology of IVF from four aspects: embryo culture, embryo selection, hormone therapy and artificial pregnancy.
Embryo culture
Embryo culture is one of the key links in IVF technology. In the past, IVF embryo culture was usually carried out in petri dishes, but now more and more hospitals have adopted more advanced incubators. This incubator adopts a closed culture system, which can provide a more stable temperature, humidity and gas environment and help to improve the success rate of embryo development. In addition, some hospitals also introduced real-time monitoring technology, which can monitor the development process of embryos around the clock to provide more accurate data and better culture conditions.
In addition, the embryo culture time of IVF also changed. In the past, embryos were generally transferred after 2-3 days of culture in petri dishes, but now, with the improvement of culture technology, embryos can be cultured in the incubator until the fifth day. This extended culture time is conducive to screening more well developed embryos and improving the implantation rate and success rate.
Finally, it is worth mentioning that some hospitals have also introduced non-invasive embryo assessment technology. Based on genetic and biochemical markers, this technology can assess the health status and potential development ability of embryos by detecting genetic abnormalities and metabolic status of embryos, thus helping doctors select the most promising embryos for transplantation.
Embryonic selection
Embryo selection is another important part of IVF technology. Traditional embryo selection is usually carried out by observing the morphological characteristics of the embryo in the culture dish, but this method has the disadvantage of strong subjectivity. Nowadays, many hospitals have adopted more advanced embryo evaluation technologies, such as combination of gene testing and visual evaluation.
Gene detection is a method to determine whether there are genetic diseases and chromosomal abnormalities by detecting the chromosome composition of the embryo. This method can help doctors screen healthy embryos and reduce the risk of transmission of genetic diseases. In addition, some hospitals also use single cell gene sequencing technology, which can detect the genome of a single embryonic cell and improve the accuracy of embryo evaluation.
Visual evaluation is a method to judge the quality of embryos by evaluating the morphology and development characteristics of embryos in culture dishes. The hospital may evaluate according to the number, symmetry and size of embryonic cells. Nowadays, some hospitals have also introduced computer-assisted embryo assessment technology to provide more objective and accurate embryo assessment results through image analysis and machine learning algorithms.
hormone therapy
Hormone therapy plays an important role in IVF technology. Hormone therapy aims to promote women to produce more eggs and control the development and excretion of follicles. In the past, hormone therapy was usually carried out by injecting drugs, but this method requires frequent injection and monitoring, which may be a great burden for patients.
However, with the progress of technology, there are now more convenient hormone treatments. Some hospitals have used local patches or nasal sprays instead of traditional injections. This method is not only convenient for patients to use, but also can provide more stable and accurate hormone concentration and improve the treatment effect.
In addition, the dosage and scheme of hormone therapy have also been improved. The hospital can adjust the dosage and administration plan of hormone individually according to the specific conditions of patients. This personalized treatment can improve the consistency and predictability of ovarian response, and increase the quality and quantity of eggs.
Artificial assisted inoculation
Artificial assisted pregnancy is the last step of IVF technology, which aims to make the embryo successfully implanted and develop into a fetus. In the past, assisted pregnancy usually used endometrial delivery technology, that is, embryos were transferred to the endometrium through catheters. However, the success rate of this method is affected by many factors, such as uterine morphology and endometrial thickness.
Now, some hospitals have introduced auxiliary technologies of artificial assisted pregnancy, such as endometrial dot injection, ultrasound-guided transplantation and endometrial replacement. These techniques can improve the accuracy and success rate of transplantation. For example, dot injection of endometrium can help adjust the thickness and blood flow of endometrium and improve the success rate of embryo implantation.
In addition, some hospitals also introduced the technology of placental stem cell transplantation, aiming to improve the health and nutrition supply of endometrium, and improve the implantation and pregnancy rate. This technology can promote the repair and regeneration of endometrium and improve the uterine environment by injecting placental stem cells into patients' endometrium.
Summary
The medical technology of IVF has made great progress in embryo culture, embryo selection, hormone therapy and artificial pregnancy. The new embryo incubator and non-invasive embryo assessment technology provide a better embryo culture environment and assessment means. Gene detection and computer-assisted embryo evaluation technology have improved the accuracy of embryo selection. Local patch and personalized hormone treatment program improved the treatment experience and effect of patients. Auxiliary technologies such as endometrial dot injection and placental stem cell transplantation have improved the success rate of artificial assisted pregnancy. With the continuous progress of science and technology, it is believed that IVF medical technology will usher in greater breakthroughs and development.
