Change of success rate of test tube babies in five generations

Test tube baby refers to the baby who transfers the fertilized egg into the mother's uterus through in vitro fertilization technology. Since Edward Stepton, a professor at Cambridge University, UK, successfully gave birth to IVF for the first time in 1978, this technology has made great progress in the medical field. With the progress of medical technology, the success rate of IVF is also increasing. This article will discuss whether the success rate of five generations of IVF has improved from many aspects.

1. Improvement of IVF technology

In vitro fertilization is the core of IVF. With the progress of science and technology, people have made continuous improvements and innovations in IVF technology. For example, this technology has developed from the initial common in vitro fertilization to intracytoplasmic sperm injection (ICSI) technology, and this technology has further evolved into intracytoplasmic sperm injection (PICSI) technology. The application of these technologies has significantly improved the pregnancy rate of IVF. The success of IVF depends largely on the technical level of the hospital. For example, the People's Hospital of Jinhua City, Zhejiang Province, China, has made significant breakthroughs in IVF technology. By introducing cutting-edge assisted reproductive technology and equipment at home and abroad, the hospital has increased the success rate of IVF by more than 10% over the past.

2. Improvement of embryo screening and culture

In addition to the improvement of IVF technology, embryo screening and culture also play a vital role in the success rate of IVF. In the past, doctors mainly relied on the appearance of embryos to screen, but this method has certain subjectivity and instability. In recent years, more and more hospitals began to use gene screening technology to screen embryos. These screening technologies can help doctors judge whether embryos carry certain genetic diseases or chromosomal abnormalities, so as to select the most promising embryos for transplantation and further improve the success rate of IVF. For example, the IVF Center of the University of California, San Francisco School of Medicine uses embryonic genomics technology to screen embryos, improving the success rate of IVF.

3. Optimization of intrauterine environment

The intrauterine environment plays an important role in the development of embryos and the success rate of transplantation. With the deepening of research, doctors have optimized the endometrial environment to improve the success rate of IVF. For example, the expert team of obstetrics and gynecology at St. Michael's Hospital affiliated to the University of Toronto in Canada found that the survival rate of IVF can be improved by adjusting the dosage of hormone and periodic monitoring, and adjusting the intrauterine environment. According to the individual differences of each patient, they provided a personalized scheme for IVF transplantation, and improved the chances of survival and implantation of transferred embryos.

4. Application of auxiliary technology

In addition to the improvement of in vitro fertilization technology, embryo screening and culture, and the optimization of the intrauterine environment, the application of assistive technology has also played a positive role in promoting the success rate of IVF. For example, the electronic endometrial culture technology that stimulates endometrial growth and the application technology of extracellular vesicles with cell extracellular matrix interaction can improve the implantation rate and pregnancy rate of transferred embryos. In general, the success rate of five generations of IVF has significantly improved in the past decades. This is due to the improvement of in vitro fertilization technology, embryo screening and culture, optimization of intrauterine environment, and the application of auxiliary technology. In the future, with the continuous development of science and technology, it is believed that the success rate of IVF has more room for improvement.
