Causes of unsuccessful IVF
The development of IVF technology has brought good news to many infertile couples. However, not all IVF babies can successfully conceive and be born. The reasons for the failure of IVF may involve many aspects. The following will elaborate on four aspects: embryo selection, hormone level control, uterine environment and quality management.
Embryonic selection
In the process of IVF, embryo selection is an important link. Embryo quality is one of the key factors affecting the success rate of IVF. Some embryos may have chromosome abnormalities, genetic diseases and other problems, which will reduce the implantation ability and development potential of embryos, leading to the failure of IVF. In addition, the embryo may also be affected by the external environment during the culture process, such as the quality of the culture medium, the operation technology of cells, etc. These factors may have adverse effects on the embryo development.
In order to improve the success rate of IVF, some hospitals have begun to use embryonic genetic screening technology to detect chromosomes, genes and other aspects of embryos, so as to screen healthy embryos for transplantation and reduce the risk of failure caused by abnormal embryos.
Hormone level control
Hormone level control is an important link in IVF. Hormone levels play an important role in ovarian function and embryo implantation. Hormone use and dose control during IVF cycle may change due to individual differences. If hormone is used improperly, follicular development will be blocked or overdeveloped, which will affect the quality of fertilized eggs and the development of embryos.
In addition, the instability of hormone level will also affect the development of endometrium, leading to the intrauterine environment is not suitable for embryo implantation. Therefore, the hospital needs to accurately control the use and dosage of hormones in the IVF cycle, make corresponding adjustments according to individual differences, and improve the success rate of IVF.
Uterine environment
The uterine environment has an important impact on the success rate of IVF. Endometrial nutrition supply, blood circulation and other factors play a vital role in embryo implantation. If endometrial dysplasia, poor blood circulation, abnormal immune environment and other problems exist, embryo implantation and development will be affected.
In order to improve the adaptability of uterine environment, some hospitals began to use assistive technology to improve the intrauterine environment. For example, the problem of endometrial adhesion can be solved by endometrial adhesion lysis; Improve endometrial blood circulation through hemodynamic monitoring and regulation, so as to improve the success rate of IVF.
Quality Assurance
The success of IVF is also related to the quality management of the hospital. IVF technology requires accurate operation and good team cooperation. The professional technical level and management ability of hospitals directly affect the achievement of results. Some hospitals may lack sufficient experience and technical strength, resulting in improper operation and lax quality control, thus affecting the success rate of IVF.
Therefore, selecting a hospital with rich experience, professional team, advanced equipment and standardized management for IVF operation can significantly improve the success rate of IVF.
Summary
The reasons for the failure of IVF can be summarized into four aspects: embryo selection, hormone level control, uterine environment and quality management. The problem of embryo quality, inappropriate use of hormone, poor adaptability of uterine environment and the technical level and management ability of hospitals will all have an important impact on the success rate of IVF. Therefore, when conducting IVF technology, it is necessary to scientifically evaluate and select hospitals, conduct accurate hormone control and embryo screening, improve the uterine environment, and ensure that hospitals have excellent technical teams and quality management systems to improve the success rate of IVF.
