What is the second generation of IVF?
The second generation of IVF babies refer to the babies that are successfully pregnant and delivered by women through in vitro fertilization embryo transfer technology. Compared with the first generation of test tube babies, the success rate of the second generation of test tube babies has improved, and they also have higher health.
The first test tube baby that successfully cultured embryos to a certain stage in the laboratory (i.e., in vitro fertilization) and successfully transplanted was born in 1978, known as the "first generation of test tube baby". With the progress and development of science and technology, people have overcome a series of technical difficulties, and the IVF technology has been continuously improved and innovated. The second generation of IVF came into being.
What is the difference between IVF and natural pregnancy?
1. Different modes of pregnancy:
IVF is conceived through in vitro fertilization, that is, sperm and eggs are combined in the laboratory to cultivate embryos, and then the embryos are transferred to the mother's uterus. Natural pregnancy refers to the combination of male sperm and eggs in women's uterus through sexual behavior.
2. Difference in pregnancy success rate:
IVF technology can help couples with fertility difficulties achieve their fertility aspirations, and natural pregnancy is the main way for human beings to reproduce. The success rate of IVF is affected by many factors, such as age, egg and sperm quality. In contrast, the success rate of natural pregnancy is more dependent on the physical condition and fertility of both couples.
3. Intervention of operation:
Test tube baby is a kind of medical technology, which requires doctors to conduct multiple operations in the laboratory to cultivate embryos, and transfer the embryos to the mother's uterus at the appropriate time. However, natural pregnancy does not involve any artificial intervention, and depends entirely on natural laws.
Development and current situation of IVF technology
The development of IVF technology has experienced years of accumulation and innovation. Now, there are many professional reproductive medical centers and specialized hospitals around the world providing IVF services.
For example, reproductive medicine centers in the United States make full use of the most advanced technology and equipment, which can help patients to solve various reproductive barriers. The Human Fertilization and Embryology Authority (HFEA) in the UK is a regulatory agency responsible for supervising and managing the operation of reproductive clinics and IVF centers to ensure the safety and reliability of technology. Peking Union Medical College Hospital in China has also made remarkable achievements in IVF technology.
With the development of IVF technology, more and more couples have successfully given birth in this way, which alleviates the problem of infertility and brings new hope to many couples who are eager to become parents.
summary
The second generation of IVF babies is obtained through in vitro fertilization embryo transfer technology. Compared with the first generation of IVF babies, the second generation of IVF babies has a higher success rate and health. The differences between IVF and natural pregnancy include: pregnancy mode, success rate and intervention of operation. IVF technology has been widely developed and applied worldwide, and many hospitals and clinics provide IVF services. In general, IVF is a technology to help couples with reproductive difficulties achieve their reproductive aspirations, bringing new hope and possibility to couples who cannot conceive naturally.
