First generation IVF
Since the birth of IVF technology in 1978, it has undergone many improvements and developments. The first generation of IVF babies are babies who use in vitro fertilization technology to transfer the fertilized eggs into the mother's uterus. The advent of this technology has brought good news to couples who cannot conceive naturally.
The success rate of the first generation IVF is not high, only about 25%. In addition, due to the immature technology, many IVF babies have some health problems at birth, such as premature delivery, low weight, etc. However, the emergence of the first generation of IVF laid the foundation for subsequent technological innovation.
The first generation of IVF is mainly carried out in relevant hospitals in the United Kingdom and the United States, the most famous of which is the University of Exeter School of Medicine in the United Kingdom. Robert Edwards and Patrick Stapleton made a historic breakthrough in this hospital in 1978, and successfully gave birth to the world's first test tube baby.
Second generation IVF
With the continuous progress of technology, IVF has entered the second generation. The second generation of IVF was mainly popularized in the 1990s, and its success rate has significantly improved compared with the first generation. This generation of IVF adopts more accurate embryo culture technology and screening methods, which improves the success rate of pregnancy and reduces the number of embryos implanted.
Compared with the first generation, the birth rate of the second generation of IVF babies has increased significantly, and the success rate can reach about 40%. In addition, compared with the first generation, the health status of the second generation of IVF infants has also improved significantly, and the rate of premature delivery and the proportion of low birth weight infants have significantly decreased.
The second generation of test tube baby has been popularized worldwide. In addition to the United Kingdom and the United States, Melbourne Test Tube Baby Center in Australia is also one of the best. The center is famous for its advanced IVF technology and professional medical team, which has helped countless couples realize their dream of becoming parents.
Third generation IVF
The third generation of IVF refers to the use of more advanced genetic technology to screen fertilized eggs in order to reduce the risk of genetic diseases. This technology first appeared at the beginning of the 21st century and became the gospel of families with hereditary diseases.
The third generation of IVF uses embryo biology technology and genetic testing tools, which can conduct comprehensive gene screening for fertilized eggs and select healthy embryos for implantation. The advent of this technology not only improves the success rate of IVF, but also significantly reduces the risk of transmission of genetic diseases.
The famous third-generation IVF centers include Boston Children's Hospital in the United States, which is world-renowned for its leading gene screening technology and professional medical team. The center has helped many couples with a family history of genetic diseases successfully give birth to healthy IVF babies.
summary
With the continuous development of IVF technology, the birth of the first generation of IVF has laid the foundation for subsequent improvement. The emergence of the second generation of IVF has significantly improved the success rate and health status of IVF. The birth of the third generation of IVF has reduced the risk of genetic diseases through advanced genetic technology, and provided new reproductive options for couples with a family history of genetic diseases.
Whether it is the first generation, the second generation or the third generation of IVF, it has brought good news to couples who cannot conceive naturally. Medical institutions such as Exeter University School of Medicine, Melbourne IVF Center and Boston Children's Hospital have made remarkable achievements in the field of IVF, making important contributions to the development and progress of global IVF technology.
