New progress of IVF technology
IVF technology is a kind of assisted reproductive technology, which has made many new progress. These new developments include: the development of embryo screening technology, the improvement of embryo implantation technology, the improvement of egg freezing technology, and the breakthrough of genetic diagnosis before embryo implantation.
Development of embryo screening technology
Embryo screening technology is an important part of IVF technology, which aims to screen healthy embryos to improve the probability of successful pregnancy. In recent years, embryo screening technology has made great progress. First, the introduction of single cell genetic diagnosis technology makes the screening of embryo chromosome abnormalities more accurate. The traditional embryo screening needs to be sampled and cultured, while single cell genetic diagnosis technology can detect single cells at an early stage, greatly reducing the damage to embryos. Secondly, the development of NGS (Next Generation Sequencing) technology enables embryo screening to more comprehensively detect chromosomal abnormalities and the risk of genetic diseases. The application of these new technologies makes it possible to select healthy embryos, and improves the probability of successful pregnancy of IVF.
Improvement of embryo implantation technology
Embryo implantation is a key step in IVF technology, and its success rate directly affects the success rate of IVF. In recent years, embryo implantation technology has been greatly improved. First, the application of minimally invasive embryo implantation technology makes embryo implantation more safe and accurate. Traditional embryo implantation requires hysteroscopy or tubal injection, which may bring many discomfort to patients. The minimally invasive embryo implantation technology can be carried out through the vagina, reducing the discomfort of patients. Secondly, the application of negative pressure assisted embryo implantation technology improves the accuracy of embryo implantation. The negative pressure assisted embryo implantation technology assists embryo implantation by negative pressure attraction, which can make the embryo attach to the inner wall of the uterus more firmly and improve the implantation rate. These improved embryo implantation technologies make the success rate of IVF continuously improve.
Improvement of egg freezing technology
Egg freezing is an important part of IVF technology, which allows women to have more time to choose the time of birth. In recent years, egg freezing technology has been improved. First, the application of ultrasonic freezing technology makes the survival rate of frozen eggs higher. Ultrasonic freezing technology can observe the inside of eggs in real time before freezing, and determine the appropriate freezing time, which improves the survival rate of eggs during freezing. Secondly, the application of low concentration freezing solution reduces the damage to egg quality caused by egg freezing. Low concentration of freezing liquid can reduce the damage of ice crystals to eggs and improve the success rate of egg freezing. The development of these technologies makes the egg freezing technology more reliable and effective.
Breakthrough in Preimplantation Genetic Diagnosis
Preimplantation genetic diagnosis is an important means in IVF technology, which is used to screen whether there are chromosome abnormalities or genetic diseases in embryos. In recent years, pre implantation genetic diagnosis has made breakthrough progress. First of all, the application of non-invasive embryonic genetic diagnosis technology avoids the damage to embryos caused by traditional diagnostic methods. The traditional embryo genetic diagnosis needs to sample the embryo, which may cause damage to the embryo. The non-invasive embryonic genetic diagnosis can be detected by the free embryonic DNA in the embryo culture medium, which reduces the interference to the embryo. Secondly, the application of PGS (Congenital Gene Screening) technology makes the diagnosis of chromosome abnormalities and genetic diseases in embryos more accurate. PGS technology can analyze every chromosome in the embryo, avoiding the limitation that traditional methods can only detect some chromosomes. These breakthroughs in new technologies make preimplantation genetic diagnosis more accurate and safe.
summary
In recent years, IVF technology has made new progress in many aspects. The development of embryo screening technology, the improvement of embryo implantation technology, the improvement of egg freezing technology and the breakthrough of genetic diagnosis before embryo implantation all provide better means and higher power for the successful pregnancy of IVF. These new developments make IVF technology play an increasingly important role in the field of assisted reproduction, and help more infertile patients achieve their reproductive dreams.
