IVF technology is a scientific and technological means to help infertile couples achieve their reproductive aspirations. The purpose is to improve the survival rate of embryos and reduce the risk of miscarriage.The following will introduce the methods and measures of IVF technology in detail from four aspects: embryo culture technology, gene detection technology, drug intervention and auxiliary technology.
Embryo culture technology
Embryo culture technology plays an important role in IVF.First, high-quality culture medium is the key to ensure the smooth development of embryos.At present, many IVF technology centers have adopted new culture media with high nutrient content and physiological regulation function, which can better simulate the environment of maternal embryo development.Secondly, the use of embryo incubators also has an important impact on the survival rate of embryos.The incubator with precise control of temperature, humidity, oxygen concentration and other factors can provide the best growth environment, improve the survival rate of embryos, and reduce the risk of abortion.Finally, embryo transfer technology is also the key link of fetal protection.By transferring embryos into the uterus, sufficient nutrition and protection can be provided to increase the success rate of embryo implantation.
Gene detection technology
Gene detection technology has important application value in IVF.First, by screening the genes of embryos, embryos with chromosome abnormalities or genetic diseases can be excluded to improve the success rate of pregnancy.At present, some hospitals have carried out embryo chromosome detection, such as PGS (Preimplantation Genetic Screening) technology.Secondly, genetic testing can also help couples understand their own genetic disease risks and avoid passing on genetic diseases to the next generation.Finally, the emergence of gene editing technology has brought new hope to IVF.CRISPR-Cas9 and other gene editing technologies can repair embryos carrying gene mutations, reduce the production of abnormal embryos, and reduce the risk of abortion.
Drug intervention
Drug intervention is one of the commonly used methods in IVF.The use of some drugs or hormones can help regulate the hormone balance in women, increase the thickness and stability of endometrium, and improve the implantation rate of embryos.For example, progesterone is a commonly used drug, which can maintain the stability of endometrium and reduce the risk of abortion by supplementing progesterone hormone.In addition, anticoagulant drugs such as low-molecular-weight heparin can also help to protect the fetus for specific patients.However, the use of drugs needs to be carried out under the guidance of doctors to avoid adverse reactions and risks.
Auxiliary technology
In addition to the above technologies, IVF can also use some auxiliary technologies to reduce the risk of abortion.First of all, the artificial mucus method is a technology that helps the embryo implant easily by artificially making mucus.Mucus can increase the viscosity of cervical passages, prevent bacteria and other harmful substances from entering the uterus, and protect the growth environment of embryos.Secondly, techniques to promote blood circulation, such as acupuncture and moxibustion, also help to improve the stability of endometrium and blood flow, and promote embryo implantation.In conclusion, IVF technology mainly includes embryo culture technology, gene detection technology, drug intervention and auxiliary technology.The survival rate and successful implantation rate of embryos can be improved and the risk of abortion can be reduced by optimizing the culture medium, artificially manufacturing mucus, gene screening, drug intervention and other means.However, the situation of each couple is different, and the selection of a suitable technology for fetal protection needs to be carried out under the guidance of a doctor.
