Definition and overview of IVF
In vitro fertilization (IVF) babies are babies born after the successful implantation of embryos into the mother's uterus by combining eggs and sperm in the laboratory through assisted reproductive technology.
Since Edward and Steptoe, winners of the British Nobel Prize, successfully implemented IVF for the first time in 1978, this technology has been widely used worldwide and has become an effective way for many infertile couples to achieve their reproductive aspirations. However, some people doubt the success rate of IVF and believe that its success rate is not stable.
Technological progress improves the success rate of IVF
With the continuous progress of science and technology, the success rate of IVF is gradually increasing. First, the continuous improvement of assisted reproductive technology, such as the development of in vitro fertilization, embryo culture, embryo screening and other technologies, has greatly improved the success rate of IVF. Secondly, research in the medical field has constantly promoted the progress of IVF technology, including hormone therapy, frozen embryo technology, etc., providing more choices for different types of infertility patients.
Taking China as an example, Peking Union Medical College Hospital is one of the earliest hospitals in China to carry out IVF technology research and clinical practice. After years of development, Peking Union Medical College Hospital has accumulated rich experience in the field of IVF, and the success rate has increased year by year. At the same time, with the continuous improvement of China's medical level, other large general hospitals, such as Shanghai Ruijin Hospital, Guangzhou Women and Children's Medical Center, have also made remarkable achievements in the field of IVF, which has solved the problem of fertility for infertile couples.
The Success Probability of IVF and Individual Factors
However, the success rate of IVF is affected by individual factors. Female age is one of the important factors affecting the success rate of IVF. The natural fertility of women decreases with age, and the success rate of IVF for women over 35 years old is low. In addition, different types of infertility will also affect the success rate. For example, infertility problems caused by endometriosis, fallopian tube blockage, etc., have a relatively high probability of success in IVF treatment.
The physical health of infertile couples will also affect the success rate of IVF. Patients with important organ diseases, severe metabolic diseases and other diseases have a low probability of success in IVF. Therefore, before IVF treatment, doctors will conduct a comprehensive physical examination of both spouses to determine whether IVF treatment is appropriate.
Future development trend of success probability of IVF
In general, with the progress of science and technology and the development of medicine, the success rate of IVF is expected to be further improved in the future. First, with the continuous improvement of assisted reproductive technology, including the wide application of gene screening technology, it will help to improve the success rate of IVF. Secondly, the in-depth research on IVF technology can provide more personalized treatment plans for different types of infertility patients, thus improving the success rate.
To sum up, the success rate of IVF has been relatively stable at present, and is expected to be further improved with the progress of technology and medicine. However, individual factors still affect the success rate of IVF. Therefore, for infertile couples, selecting appropriate hospitals and doctors for comprehensive physical examination and evaluation is an important step in selecting IVF treatment.
