Causes of IVF failure
IVF technology is an important means to help infertile couples achieve their reproductive dreams. However, there are still a certain proportion of IVF failures. The reasons can be explained from the following aspects.

Scientific factors
Scientific factors are an important reason for the failure of IVF. First, the success rate of IVF is closely related to women's age. With the growth of age, the quality of female eggs decreases, the number of eggs decreases, and embryos are prone to chromosomal abnormalities, leading to transplant failure or abortion. Secondly, the fertilization process may be interfered by various factors, such as the quality of fertilized eggs, implantation conditions and abnormalities in the process of embryo development. These scientific factors may lead to the failure of IVF.
Although scientific progress has made IVF technology gradually mature, there are still many unknown factors. The IVF technology and operation methods adopted by different hospitals will also be different, leading to different success rates. Therefore, scientific factors are an important factor leading to the failure of IVF.
Lifestyle factors
Lifestyle factors are also an important reason for IVF failure. First of all, bad living habits will have a negative impact on embryonic growth and development. Smoking, excessive drinking, unreasonable diet and other bad habits will increase the risk of IVF failure. Secondly, pressure is also an important factor leading to the failure of IVF. Stress will lead to endocrine disorder in the body and affect ovarian function, thus reducing the success rate of IVF.
Therefore, both husband and wife should maintain good living habits, which is not only beneficial to their own health, but also can create favorable conditions for the success of IVF.
psychological factor
Psychological factors are an important reason for IVF failure. The pressure, anxiety, worry and uneasiness in the process of IVF will have a negative impact on the body, thus affecting the success rate of IVF. Psychological factors have an impact on female hormone secretion, egg quality, endometrial thickness, etc. In addition, the lack of understanding and support of both spouses in the IVF process will also increase the risk of IVF failure.
Therefore, both husband and wife should maintain a positive and optimistic attitude, alleviate stress and anxiety, actively cooperate with the doctor's treatment, and increase the success rate of IVF.
Hospital technical factors
Hospital technology is also an important reason for IVF failure. The equipment and operation level of IVF technology in different hospitals are different. Hospitals without sufficient experience and expertise may make some mistakes in the operation process, which will affect the success rate of IVF. In addition, the hospital environment and health conditions will also have a certain impact on the success of IVF.
Therefore, when choosing a hospital for IVF operation, both husband and wife should take into account the hospital's technical level, advanced equipment and credibility to ensure that the appropriate hospital is selected for IVF operation.
Summary
The failure of IVF may be caused by multiple factors. Scientific factors, lifestyle factors, psychological factors and hospital technical factors may affect the success rate of IVF. Therefore, both husband and wife should actively cooperate with the doctor for treatment, maintain good living habits in daily life, relieve psychological pressure, and choose a suitable hospital for treatment. Only by comprehensively considering these factors can we improve the success rate of IVF and finally realize the fertility aspirations of couples.
