International development status of IVF technology
IVF technology is a method of in vitro fertilization and embryo transfer to help couples who are unable to conceive naturally achieve their reproductive aspirations. With the progress of science and technology and the development of medicine, IVF technology has been widely used worldwide. This article will elaborate on the international development status of IVF technology from four aspects: the type, application scope, success rate and ethical and moral issues of artificial assisted reproduction technology.
1、 Types of ART
Assisted reproductive technology includes two main methods: in vitro fertilization and embryo transfer. In IVF, doctors combine sperm and eggs in the laboratory, cultivate embryos, and then transplant them into the mother's uterus for pregnancy. Embryo transfer is to transfer the fertilized and cultivated embryos into the mother's uterus to make them develop into fetuses.
At present, in vitro fertilization and embryo transfer technology has been widely used in the world, and become an important means for infertile couples to achieve their reproductive aspirations. And with the development of science and technology, artificial assisted reproduction technology is also constantly innovating and improving, providing hope for more infertile couples.
2、 Application scope and success rate
IVF technology is widely used. In addition to simple infertile couples, IVF technology is also applicable to patients with unexplained infertility, polycystic ovary syndrome, fallopian tube blockage and other diseases. At the same time, IVF technology also provides a chance for couples at risk of genetic diseases to choose healthy embryos.
According to the data of the World Health Organization, the success rate of IVF technology is about 30% worldwide. The technical level, treatment experience, equipment conditions and other factors of different countries and hospitals will have a certain impact on the success rate.
3、 Ethical and moral issues
The development of IVF technology has also brought a series of ethical and moral issues. Among them, the most concerned are the application of embryo processing and genetic gene editing. Because the IVF technology requires multiple experiments and embryo cultivation process, it has also triggered discussion on the ethical and moral issues of embryos.
In addition, the application of genetic gene editing technology has also attracted people's attention and discussion. Through genetic gene editing technology, the genes of embryos can be modified to eliminate the risk of genetic diseases. But it also involves the ethical issues of human genetic transformation, which requires scientific research and application on the basis of respecting human dignity and social ethics.
4、 Summary
IVF technology has been widely used in the world. Assisted reproductive technology includes in vitro fertilization and embryo transfer, which can be applied to infertile couples and couples with genetic disease risk. The success rate is about 30%. The technical level and conditions of different countries and hospitals will affect the success rate. The development of IVF technology has also raised ethical and moral issues, especially the application of embryo processing and genetic editing technologies. While promoting technological development, it is also necessary to fully consider the issues of ethics and social values to ensure the application of science and social progress.
