Possible mismatch of IVF
Test tube baby is an assisted reproductive technology, which combines sperm and eggs in vitro culture, and then transfers embryos to the mother to realize the process of pregnancy and delivery. However, in the whole process, due to various reasons, some mismatches may occur. The following are possible mismatches of IVF:
Embryo selection error
Embryo selection is one of the keys to the success of IVF. After in vitro fertilization, doctors usually select the most promising embryos from multiple fertilized eggs for transfer. However, due to human factors or technical reasons, errors may occur in the process of embryo selection. For example, the transfer of poorly developed embryos by mistake may lead to pregnancy failure or embryo termination. In addition, if doctors transfer multiple embryos, it may also increase the risk of multiple pregnancies.
In order to reduce embryo selection errors, doctors need to carefully observe and evaluate the development of embryos, and select the best embryo transfer.
Mismatch during fertilization and embryo culture
Fertilization and embryo culture are the key steps of IVF. However, mismatches may also occur in this process. For example, the pairing of eggs and sperm may be wrong, resulting in mismatching of parental genes or unexpected gender. In addition, when culturing embryos, doctors may make mistakes in the preparation of embryo culture medium, which may lead to the obstruction or abnormality of embryo development.
In order to avoid the mismatch in the process of fertilization and embryo culture, doctors need to operate in strict accordance with the operating procedures and set strict quality control standards in the laboratory environment.
Mismatch of embryo transfer
Embryo transfer is the last and most critical step of IVF. In the process of embryo transfer, embryo transfer position error or embryo implantation failure may occur. Some studies also show that the implantation quality of embryos and the environmental factors in the mother may also affect the survival rate of IVF.
Doctors need to carefully select the appropriate embryo transfer location and follow the operating procedures during the transfer process. At the same time, it is also helpful to improve the success rate of embryo transfer by controlling the patient's internal environment, such as adjusting hormone levels or endometrial thickness.
Errors in screening for genetic diseases in infants
In vitro babies are usually screened for genetic diseases before embryo transfer. This screening can help doctors exclude embryos carrying genetic disease genes, thereby reducing the risk of genetic diseases in infants. However, due to technical and human factors, errors may occur in the screening process of infant genetic diseases.
In order to reduce the errors in screening genetic diseases of infants, doctors need to select appropriate screening methods and strictly follow the operating procedures when implementing screening.
In conclusion, IVF may have multiple mismatches in the whole process. Doctors need to have rich experience and professional knowledge, and operate in strict accordance with operating procedures to reduce the risk of mismatch and improve the success rate of IVF.
