Differences between the first and second generation of IVF
The continuous progress of IVF technology has made many infertile couples realize their desire to have children. With the passage of time, IVF technology has also been developing. From the first generation of IVF to the second generation of IVF today, there are many differences. This article will elaborate on the differences between the first generation and the second generation of IVF.
1、 Technical maturity
The first generation of IVF was born in 1978, and was successfully implemented by British biologists Robert Edwards and Patrick Sterney Brown. The first generation of IVF technology is relatively elementary, with low technical maturity and success rate. In contrast, after decades of development and research, the second-generation IVF technology has made great breakthroughs, with a high degree of technical maturity and a greatly improved success rate.
In the second generation of IVF technology, more advanced IVF technology has been introduced, which has greatly improved the success rate of pregnancy. In addition, the second generation of IVF has also added technologies such as gene screening and gene editing to screen out some genetic diseases and defects, and conduct gene editing at the early stage of embryonic development to improve the birth rate of healthy infants.
2、 Selection of IVF
The first generation of IVF technology can only select one embryo to be transferred into the uterus, and cannot make other kinds of choices. Relatively speaking, the second generation of IVF technology can select more embryos for detection and improve the accuracy of screening. This means that parents can choose embryos with better genetic genes, which will reduce the occurrence of genetic diseases and defects, while improving the overall health of the baby.
In addition, the second-generation IVF technology can also make gender selection. This means that parents can choose male or female embryos for transplantation according to their own needs, which is of great significance for couples with special needs or who want to achieve gender balance.
3、 Safety of IVF
Due to the low maturity of the first generation IVF technology, there are certain risks. For example, the probability of multiple pregnancy is high, and embryo transfer is vulnerable. However, with the progress and development of technology, the safety of the second generation IVF technology has also been greatly improved.
The second generation of IVF technology introduces more advanced embryo transfer methods, which can reduce the risk of multiple pregnancy. In addition, the introduction of technologies such as gene screening and gene editing can also reduce the occurrence of genetic diseases and defects and improve the overall health of infants. Therefore, compared with the first generation of IVF, the second generation of IVF has higher safety.
4、 Cost of IVF
At the early stage of the development of the first generation IVF technology, due to the low maturity of technology and expensive equipment, the cost was high. However, with the development and maturity of the second generation IVF technology, the popularity of equipment and the decline of cost, the cost of IVF treatment has gradually decreased.
At present, some medical institutions provide IVF treatment packages, including multiple cycles of treatment and a series of testing projects. In addition, medical insurance has begun to cover related costs, reducing the economic burden of patients. Therefore, compared with the first generation of IVF, the cost of the second generation of IVF is more reasonable and affordable.
Summary
To sum up, the differences between the first generation and the second generation of IVF are mainly reflected in technology maturity, selection of IVF, safety and cost of IVF. Compared with the first generation, the second generation IVF technology is more mature, with higher success rate, more embryo selection and better security, and more reasonable and affordable costs. With the continuous development of science and technology, IVF technology will continue to improve and perfect, bringing more benefits to infertile couples.
