Safety and reliability of the first generation of IVF
The emergence of IVF technology provides a way for couples who could not conceive naturally to have children. The first generation of test tube babies was born in 1978. This new technology has brought hope, but it has also raised concerns about safety and reliability.
First of all, the first generation of IVF requires more invasive surgery on women, that is, egg retrieval process. This process requires gynecologists to quickly take eggs from the female ovary in vitro, and then conduct in vitro fertilization with sperm. This operation may cause gynecological complications, such as fallopian tube obstruction, ovarian cysts, etc.
Secondly, the success rate of the first generation of IVF is relatively low. Due to the immature technology, less than 30% of IVF embryos can be successfully implanted into the uterus. This means that couples need to try many times to get pregnant successfully, which is a huge challenge for the family's economic and psychological pressure.
In addition, the risk of genetic diseases of the first generation of IVF is also high. In the process of in vitro fertilization of sperm and eggs, it is difficult to exclude some embryos carrying genetic disease genes. This has led to some test tube babies suffering from their own genetic diseases after birth.
Safety and reliability of the second generation of IVF
With the progress of science and technology, the safety and reliability of the second generation of IVF has significantly improved compared with the first generation.
First, the second-generation IVF technology introduced minimally invasive technology in the process of egg retrieval. Modern hospitals such as Peking Union Medical College Hospital and Shanghai Jiaotong University Children's Hospital have widely used minimally invasive technology for IVF egg retrieval. This kind of operation is safer and more reliable than the traditional egg retrieval operation, and can reduce the risk of gynecological complications.
Secondly, the second-generation IVF technology has made a major breakthrough in embryo screening. By pre implantation genetic diagnosis (PGD) of embryos, doctors can detect the genetic information of embryos in detail, and further exclude embryos carrying genetic disease genes. This greatly reduces the risk of IVF disease and makes the baby healthier after birth.
In addition, the success rate of the second generation of IVF has also been significantly improved. In recent years, the success rate of IVF has reached more than 50%, which has made great progress compared with the first generation of IVF. This means that couples can successfully conceive with only one or a few attempts, reducing the financial and psychological pressure.
Conclusion and prospect
To sum up, the second generation of IVF is safer and more reliable than the first generation. The application of minimally invasive technology and PGD has made the IVF egg retrieval process safer, the embryo screening more accurate, and the success rate significantly improved. However, with the continuous development of science and technology, there is still more room for improvement. In the future, we can expect IVF technology to further improve, bringing more hope and joy to those couples who are eager to have children.
