Is the success rate of second-generation IVF reliable?
In recent years, with the continuous development of science and technology, second-generation IVF has become the choice of many infertile couples. However, people have doubts about whether the success rate of the second generation IVF is reliable. This article will discuss this problem from different angles.
Success rate in clinical practice
First, we can analyze the success rate of second-generation IVF from the perspective of clinical practice. The second-generation IVF babies usually need the help of assisted reproductive technologies, such as in vitro fertilization (IVF) and embryo transfer. According to the statistics of major hospitals around the world, the success rate of second-generation IVF is different among different hospitals. For example, the data of Peking Union Medical College Hospital shows that the success rate of its second-generation IVF is about 60%, while the data of the First People's Hospital affiliated to Shanghai Jiaotong University shows that the success rate is about 75%. The difference in the success rate of different hospitals may be related to the level of medical technology, physician experience and other factors.
Secondly, it is worth noting that the success rate of the second generation of IVF is also different in different age groups. According to Swedish follow-up study data, when women are under 35 years old, the success rate of second-generation IVF is about 40% to 50%; When women are over 35 years old, the success rate will decline significantly, only about 20% to 30%. Therefore, choosing the right age for the second generation IVF may have an important impact on the success rate.
In addition, the physical conditions of both spouses will also have an impact on the success rate of second-generation IVF. Different health conditions will affect the quality of fertilized eggs, embryo implantation, implantation and other links, thus affecting the success rate of second-generation IVF. For example, some chronic diseases, genetic diseases and other factors may reduce the success rate.
Support of scientific research data
In addition to the observation results of clinical practice, scientific research data also have reference value for the success rate of second-generation IVF. Many studies have shown that the selection of high-quality sperm and eggs for fertilization, as well as the application of embryo quality assessment and screening techniques, can improve the success rate of second-generation IVF. For example, a study conducted by Nanjing Union Medical College Hospital showed that by selecting the best embryo transfer and embryo quality assessment technology, the success rate of its second-generation IVF increased from 40% to 60%.
In addition, the study also found that factors such as the choice of drugs for ovulation promotion and embryo transfer, and the reasonable dosage of drugs may also have an impact on the success rate of second-generation IVF. For example, the research of West China Hospital found that the use of artificial cycle ovulation promoting drugs alone would significantly improve the success rate of second-generation IVF compared with combined ovulation promoting drugs.
In conclusion, the support of scientific research data has further strengthened the reliability of the success rate of second-generation IVF.
Influence of psychological factors
However, whether the success rate of second-generation IVF is reliable still needs to consider the influence of psychological factors. Infertility couples often have greater expectations and pressure when carrying out second generation IVF, which may also have a certain impact on the success rate. Research shows that negative mental states such as anxiety and stress may affect women's pregnancy rate. Therefore, in the process of second-generation IVF, it is of great significance to actively adjust the psychological state to improve the success rate.
conclusion
To sum up, the success rate of second-generation IVF is reliable. According to the clinical practice results and scientific research data, there are differences in the success rate between different hospitals, and age, physical condition and other factors will also affect the success rate. At the same time, psychological factors such as anxiety and pressure also have a certain impact on the success rate. Therefore, when choosing the second-generation IVF, we should choose a regular hospital, plan the childbearing age in advance, and adjust the psychological state to improve the success rate.
