Failure rate of test tube babies in Shanghai Red House
1. Operation failure rate
Shanghai Red House is a hospital specializing in IVF. Although the technology and equipment are very advanced, IVF surgery itself has a certain failure rate. In vitro baby surgery, women need to collect eggs, and then transplant the fertilized eggs into the uterus after cultivating them to a certain stage in the laboratory. There are many uncertain factors in this process, which may lead to the possibility of failure of the operation.
First of all, during the egg collection process, it may not be possible to obtain enough eggs in quantity and quality, which is critical to improve the success rate of surgery. In the process of egg collection, doctors need to conduct ovarian puncture through hysteroscope or pelvic endoscope under the guidance of ultrasound to extract eggs. However, the number and quality of eggs are closely related to women's age and ovarian function, so older women or women with poor ovarian function may collect fewer eggs.
Secondly, the cultivation and selection of fertilized eggs is also an important link in IVF surgery. In the process of IVF, not all eggs can be successfully fertilized, and sometimes the fertilized eggs may stop developing during the cultivation process, leading to the failure of surgery.
Finally, the migration process may be difficult. Even if healthy embryos are successfully cultivated, the process of intrauterine transfer may encounter difficulties. For example, problems such as the thickness and quality of the endometrium and the anatomical structure of the uterus may have an impact on embryo transfer, leading to the failure of IVF surgery.
2. In vitro fertilization failure rate
In vitro fertilization is a key step in IVF surgery, and its failure rate is also one of the factors affecting the success rate of IVF surgery. In vitro fertilization requires the combination of sperm and egg in the laboratory to form a fertilized egg, and then the fertilized egg is cultivated to a certain development stage before transplantation.
However, there are many reasons for IVF failure. First, sperm quality may affect the success rate of IVF. The number, morphology and mobility of sperm are key factors affecting the fertilization rate. If the number of sperm is insufficient or the quality of sperm is poor, the success rate of IVF will be affected.
Secondly, the maturity and quality of eggs also play an important role in the success rate of IVF. Only a mature egg can successfully combine with sperm to form a fertilized egg. At the same time, the quality of the egg will also affect the development ability of the fertilized egg.
In addition, the level of laboratory operation technology is also one of the key factors determining the success rate of IVF. Laboratory staff need to operate under strict sterile conditions to ensure that the combination of eggs and sperm can be carried out smoothly. If the operation is improper, it is easy to lead to fertilization failure.
3. Failure rate of IVF transplantation
In IVF operation, the transfer of fertilized embryos is an important link, and it is also a part with high requirements for operation technology. The failure rate of IVF transplantation is mainly affected by the following factors.
First of all, the choice of embryo transfer is an important factor. In IVF surgery, doctors usually choose the healthiest and most promising embryos for transplantation, but even the healthiest embryos may not be able to successfully implant and develop into babies.
Secondly, the quality and thickness of endometrium also have a certain impact on the success rate of IVF transplantation. The endometrium needs a certain thickness and quality to provide sufficient nutrition and environment for the fertilized embryo and promote the implantation and development of the embryo.
Finally, the use of progesterone and other drugs may also affect the success rate of IVF transplantation. Progesterone is a commonly used substitute for progesterone, which is used to promote the development of endometrium and maintain pregnancy. However, if the progesterone dosage is not accurate or the use time is improper, it may affect the development of endometrium, leading to the failure of IVF transplantation.
4. Influence of psychological and physiological factors on failure rate
In addition to physiological factors, the failure rate of IVF surgery is also affected by psychological and physiological factors. IVF surgery is a major psychological pressure for both husband and wife. If there are anxiety, tension, depression and other negative emotions before or during the operation, it may affect the recovery after the operation and the success rate of the operation.
In addition, the lifestyle and habits of both spouses will also have a certain impact on the failure rate of IVF surgery. For example, smoking, drinking, excessive mental stress, irregular work and rest time and other factors may affect the success rate of IVF surgery.
To sum up, Shanghai Red House, as a hospital specializing in IVF, has advanced technology and equipment, but IVF surgery still has a certain failure rate. The failure rate of surgery is mainly affected by the risk factors of surgery itself, the failure rate of in vitro fertilization, problems in the process of transplantation, and psychological and physiological factors. For those couples who plan to perform IVF surgery, they need to understand and fully consider the risk of failure of the surgery, and choose a hospital with rich experience and good reputation for surgery to maximize the success rate of the surgery.
