Success rate of the third generation IVF technology
The third generation IVF technology is an important breakthrough in the field of modern medicine. It helps couples who cannot conceive in a natural way to realize their reproductive dreams through assisted reproductive technology. However, the success rate and risk are important factors that couples must face when considering this technology. The success rate of the third generation IVF technology will be described in detail below.
First of all, the success rate of the third generation IVF technology is affected by many factors, including female age, egg quality, experience level of embryo transfer and assisted reproductive hospitals. According to the statistics of some well-known hospitals in China, the success rate of young and healthy women under 35 years old using the third generation IVF technology can reach more than 50%. However, with the growth of women's age, the success rate gradually declined. The success rate of women aged 30-35 is 40% - 50%, that of women aged 35-40 is 30% - 40%, and that of women over 40 is less than 20%.
Secondly, egg quality is also an important factor affecting the technical success rate of the third generation IVF. The quality of eggs directly determines the success rate of fertilization and embryo transfer. Better egg quality will improve the fertilization rate and embryo quality, and increase the success rate. However, it is not easy to promote better egg quality, because egg quality is closely related to women's age, living habits, basic health status, etc. Therefore, before the third generation IVF technology, doctors will evaluate women to assess the egg quality, and formulate more reasonable treatment plans based on the evaluation results to improve the success rate.
Third, the method and quality of embryo transfer also play an important role in the success rate. At present, embryo transfer is mainly divided into natural cycle and artificial cycle. Natural cycle refers to embryo transfer according to women's normal menstrual cycle, while artificial cycle refers to regulating women's menstrual cycle through drug intervention. According to hospital statistics, the success rate of artificial cycle is higher than that of natural cycle, because under artificial cycle, doctors can predict and control women's menstrual cycle to improve the success rate of embryo transfer. In addition, embryo quality will also directly affect the success rate. The healthier the embryo, the higher the success rate.
Finally, the experience level of assisted reproductive hospitals also has an important impact on the success rate of the third generation IVF technology. The professional technology, equipment and quality of the medical team of the assisted reproduction hospital will directly affect the accuracy and success rate of the operation process. Therefore, when choosing an assisted reproduction hospital, couples need to examine factors such as the qualification, professional background and successful cases of the hospital.
Risks of the third generation IVF technology
In addition to the success rate, the third generation IVF technology still has certain risks. Although the development of technology and the improvement of medical level have greatly increased the probability of healthy birth of babies, there are still some risks that need couples' attention.
First, drug allergy is a common risk when carrying out the third generation IVF technology. When conducting controlled ovarian hyperstimulation (COH), doctors will use ovulation promoting drugs to increase the egg production and the success rate of egg retrieval. However, these drugs can also lead to some uncomfortable reactions, such as abdominal distension, breast pain, mood fluctuations, etc. Although adverse reactions usually do not cause serious harm to the body, attention should be paid to the dosage and use method to reduce the risk of adverse reactions.
Secondly, there may be some risks in the process of egg retrieval. In the process of ovarian ovulation promotion, doctors will use ultrasound guided technology to take eggs. This process may lead to some complications, such as abdominal bleeding after ovarian puncture, uterine cavity hematocele, etc. Although the probability of these complications is very low, doctors still need to have some experience to ensure the safety of the operation.
In addition, the success rate of blastocyst implantation after embryo transfer also has certain risks. According to data statistics, the success rate of blastocyst transfer is only about 30% - 40%, which means that not every successfully transferred embryo can be successfully implanted. This is one of the reasons why some transplant cycles fail to conceive successfully.
Finally, due to the limited number of embryo transfer options, some couples may need to try several times to successfully conceive. This will lead to an increase in the time and economic investment of couples, and bring some psychological pressure. Therefore, when choosing the third generation IVF technology, couples need to be prepared psychologically and financially.
summary
The success rate of the third generation IVF technology is affected by many factors, including female age, egg quality, experience level of embryo transfer and assisted reproductive hospitals. The success rate of young and healthy women under 35 years old using this technology is higher, and the success rate gradually decreases with age. The quality of eggs, the way and quality of embryo transfer, and the experience level of assisted reproductive hospitals are also important factors affecting the success rate.
However, the third generation IVF technology also has certain risks. Drug allergy, possible complications during egg retrieval, blastocyst implantation success rate after embryo transfer, and the need for multiple attempts are all risk factors for couples to pay attention to.
Therefore, when choosing the third generation IVF technology, couples should fully understand the success rate and risks of the technology, and choose an experienced assisted reproductive hospital for operation, so as to increase the success rate and reduce the risks. In addition, psychological and economic preparation is also very important. Couples need to make psychological adjustment and full economic preparation to cope with possible multiple attempts and uncertainties.
