Successful technology of IVF
IVF refers to the process of promoting pregnancy by culturing the fertilized eggs in vitro and then implanting them into the mother. Since the birth of the first test tube baby, Louis Brown of the UK in 1978, the technology of test tube baby has made great progress and success. Next, we will introduce the successful technology of IVF from different aspects.
1. In vitro fertilization technology
In vitro fertilization (IVF) is one of the key steps in IVF. The technology mainly includes the collection of eggs and sperm, and then the fertilization of eggs and sperm in vitro. A common in vitro fertilization technique is in vitro fertilization embryo transfer (IVF-ET). In the IVF-ET process, doctors will use ultrasound guided needles to inject sperm into eggs, then cultivate the fertilized eggs into embryos, and finally transfer the embryos to the uterus of women.
The success of IVF depends on many factors, such as the quality of eggs and sperm, the quantity and quality of embryos implanted, and the state of endometrium. Some hospitals, such as Johns Hopkins Hospital in the United States and London Reproductive Medicine Center in the United Kingdom, have rich experience and high success rate in IVF technology.
2. Congenital gene diagnosis technology
Congenital gene diagnosis technology is to carry out gene detection on embryos before in vitro fertilization to screen out possible genetic diseases or chromosomal abnormalities. This technology can help doctors choose healthy embryos for transplantation and reduce the risk of bad gene transmission.
Fortunately, with the development of advanced gene sequencing technology, the detection of various gene abnormalities and genetic diseases is becoming more accurate and reliable. For example, the University of Washington School of Medicine in the United States has launched a gene screening project, which can screen 1000 genetic diseases through cinemas.
3. Frozen embryo technology
Frozen embryo technology refers to the freezing of surplus embryos for future use. This can avoid repeated ovarian stimulation and egg collection process for women, and reduce the burden on the body. In addition, frozen embryo technology can also improve the chances of success of IVF, because in the future cycle, doctors can choose the best time to carry out embryo transfer to improve the implantation rate.
The development of this technology stems from the gradual improvement of frozen and thawed embryos. At present, liquid nitrogen freezing and gradual freezing are two common frozen embryo technologies. Some famous hospitals, such as Peking Union Medical College Hospital in China and Harvard Medical School in the United States, have successfully used frozen embryo technology to store and use embryos.
4. Assisted reproductive technology
Assisted reproductive technology (ART) consists of several sub technologies aimed at improving the chances of success of IVF. For example, embryo incubation technology and sperm selection technology. Embryo incubation technology refers to maintaining the fertilized egg/embryo in vitro under specific culture conditions to improve the quality of embryo development. Sperm selection technology is to select high-quality sperm through in vitro operation to improve fertilization rate and pregnancy rate.
With the continuous progress of technology, assisted reproductive technology is more and more widely used in the process of IVF. Many IVF hospitals around the world have the latest assisted reproductive technology equipment and experienced doctors.
Summary
The successful technologies of IVF include in vitro fertilization, congenital gene diagnosis, frozen embryo technology and assisted reproduction technology. The continuous development and improvement of these technologies provide hope for couples who cannot conceive naturally. The success rate of IVF technology is constantly improving whether it is through improving the fertilization rate, screening genetic diseases, or selecting the best time for embryo transfer. In the future, with the continuous progress of science and technology, these technologies will become more accurate, safe and reliable, and realize the dream for more couples who want to have healthy babies.
