Core technology of the third generation of IVF
As a kind of assisted reproductive technology, IVF technology has developed to the third generation. The third generation of IVF technology is more advanced than the previous technology, which adopts a series of new core technologies, greatly improving the success rate and health of IVF. So what is the core technology of the third generation of IVF? This article will elaborate from four aspects: embryo screening, hormone therapy, in vitro fertilization and embryo culture.
Embryo screening
Embryo screening is one of the keys to the success rate of IVF. In the third generation of IVF, a new generation of gene detection technology was used for embryo screening. By genome analysis of a small number of cells in the embryo, the number, structure and abnormality of chromosomes can be determined early after fertilization. This technology can effectively screen out healthy embryos, prevent embryos with chromosome abnormalities from being implanted into the uterus, improve the success rate of pregnancy and reduce the abortion rate.
In addition to chromosome screening, embryo screening can also be used for genetic disease gene screening. By gene sequencing of the fertilized egg, it can be determined that the embryo carrying the genetic disease mutation gene. In this way, healthy embryos can be selected for transplantation before implantation into the uterus, reducing the risk of genetic diseases and improving the health quality of IVF.
It is worth mentioning that the embryo screening technology needs to be carried out in the laboratory. At present, many famous reproductive hospitals in the world can provide this service, such as the California Reproductive Medical Center in the United States.
hormone therapy
Hormone therapy is one of the key steps for the success of IVF. In the third generation of IVF, hormone therapy technology has been further improved. Hormone therapy mainly includes ovulation induction therapy and endometrial preparation therapy.
Ovarian stimulation therapy can stimulate the ovary to produce more follicles and eggs and increase the chance of pregnancy through the use of ovulation promoting drugs. The third-generation ovulation promoting drugs are more accurate and can be adjusted according to individual conditions, greatly improving the success rate of IVF.
Endometrial preparation treatment mainly includes adjusting the thickness and quality of endometrium. In the third generation of IVF, doctors can more accurately control the use of hormones, make the endometrium reach the best thickness and quality, and provide a good environment for embryo implantation.
In vitro fertilization
In vitro fertilization is one of the key steps in IVF technology. In the third generation of IVF babies, IVF technology has been further improved and perfected. In vitro fertilization technology mainly includes two steps: egg retrieval and sperm retrieval.
Egg retrieval refers to the puncture of mature follicles in the ovary to remove eggs under the guidance of ultrasound. The third generation of IVF adopts more accurate egg retrieval technology, which makes the process of egg retrieval more safe and reliable.
Sperm extraction refers to obtaining sperm from the male body. In addition to conventional natural ejaculation and sperm washing techniques, the third generation IVF introduced sperm quality assessment and selection techniques to ensure that only high-quality sperm is used for IVF.
Embryo culture
Embryo culture is one of the key links in IVF technology. In the third generation of IVF, embryo culture technology has been better improved.
Embryo culture medium is one of the important environmental factors in embryo culture. The third generation of IVF uses a new generation of embryo culture medium, providing a more suitable environment for embryo development.
At the same time, the continuous culture system was introduced into the embryo culture technology. Through the continuous culture system, embryos can be monitored 24 hours without interference to improve the success rate of embryo development.
Summary
The core technologies of the third generation of IVF mainly include embryo screening, hormone therapy, in vitro fertilization and embryo culture. The continuous improvement and perfection of these technologies have greatly improved the success rate and health of IVF. Healthy embryos can be screened through embryo screening to reduce the risk of chromosomal abnormalities and genetic diseases; Hormone therapy can promote the development of eggs and embryos and provide a good environment for embryo implantation into the uterus; In vitro fertilization can ensure the use of high-quality sperm for fertilization; Embryo culture provides a more suitable environment for embryo development. The continuous progress of the third generation technology of IVF will bring new hope to infertile families.
