What is the principle of the third generation IVF technology?
IVF technology is an assisted reproductive technology designed to help couples who cannot conceive naturally achieve their reproductive aspirations. With the development of science and technology, the third generation IVF technology has gradually become a more efficient and accurate solution. The third generation IVF technology mainly includes the progress in enhanced optical selection, single cell gene detection, liquid biopsy and environmental simulation culture.
Enhanced optics selection
Enhanced optical selection is an important part of the third generation IVF technology. In traditional IVF technology, doctors can only observe and screen the fertilized eggs with naked eyes. The third generation IVF technology has introduced advanced equipment such as high-power microscope, polarizing microscope and laser beam, which can more accurately observe the morphology and development of fertilized eggs. Through enhanced optical selection, doctors can select fertilized eggs with normal appearance and sound shape to improve the implantation rate and pregnancy success rate.
Single cell gene detection
The third generation of IVF technology also introduces single cell gene detection technology, which greatly improves the accuracy of embryonic genetic screening. Traditional embryonic genetic screening needs to take some cells for detection, which may lead to inaccurate detection results or embryonic development blocked. Single cell gene detection technology allows gene analysis on each cell of each embryo, which can more accurately detect genetic diseases, chromosome abnormalities and gene mutations. Through single cell gene testing, doctors can screen healthy embryos and reduce the genetic risk of congenital diseases.
Liquid biopsy
Liquid biopsy is an important innovation of the third generation IVF technology. Traditional embryo biopsy needs to take a part of tissue for detection, sometimes it may cause some damage to the embryo. Liquid biopsy embeds cells into the embryo culture medium by technical means, and obtains relevant information by analyzing the genetic material in the culture medium. This non-invasive biopsy method will not harm the embryo, and can obtain accurate genetic information, which is helpful to evaluate the quality of embryo development.
Environmental simulation cultivation
The third generation IVF technology also introduced environmental simulation technology in the process of embryo culture, which can better simulate the intrauterine environment and improve the survival rate and development quality of embryos. By controlling the temperature, humidity, pH value, gas concentration and other factors in the incubator, doctors can create a more suitable environment for embryonic development. This environmental simulation culture technology makes the development of embryos in vitro more close to nature, which helps to improve the success rate of embryo transfer.
To sum up, the third generation IVF technology has improved the success rate of IVF and the accuracy of genetic screening by enhancing the innovation in optical selection, single cell gene detection, liquid biopsy and environmental simulation culture. These innovative technologies make IVF more accurate and reliable, providing better choices for infertile couples to realize their dreams of childbirth.
