Risk and index increase of IVF fetal arrest
With the development of the times, the IVF technology has become increasingly mature, and more and more couples have realized their reproductive dreams through this technology. However, IVF is not a completely negligible method, and fetal arrest is one of the risks. This article will elaborate on the risk and index increase of IVF fetal arrest from the aspects of treatment plan selection, maternal age, embryo quality and auxiliary technology.
Treatment scheme selection
In IVF treatment, different treatment schemes may affect the risk of fetal arrest. First, the use of ovulation promoting drugs may increase the risk of multiple pregnancy, and multiple pregnancy itself is a major factor in the risk of fetal arrest. Therefore, when choosing a treatment plan, doctors need to balance the probability of multiple pregnancy and the risk of fetal arrest according to the specific situation of the patient.
Secondly, the number of embryo transfers may also affect the risk of fetal arrest. Research shows that the success rate of single embryo transfer is relatively high, and the risk of fetal development abnormalities and fetal arrest is low. Therefore, for older patients or patients with multiple IVF failures, single embryo transfer is recommended to reduce the risk of fetal arrest.
In addition, for patients who have lost embryos, egg retrieval and embryo culture may need to be carried out again, which may also increase the risk of IVF abortion. Therefore, in the choice of treatment plan, doctors need to comprehensively consider the specific conditions of patients and technical means to reduce the risk of fetal arrest.
Maternal age
Maternal age is one of the important factors affecting the risk of IVF fetal arrest. The number and quality of female eggs decrease with age, and the ability to support embryonic development also decreases. Studies have shown that the risk of IVF abortion is significantly increased in women over 35 years of age. Therefore, older women need to pay more attention to monitoring and regulation during IVF treatment to avoid the risk of fetal arrest.
In addition, older women may be accompanied by other reproductive system diseases or potential fertility problems, which may also increase the risk of fetal arrest. Therefore, before IVF treatment, it is necessary to conduct a comprehensive reproductive system assessment and related examinations, and develop personalized treatment plans according to the specific conditions of patients.
Embryo quality
Embryo quality is one of the important factors that affect the risk of IVF abortion. The quality of embryo directly affects the probability of embryo implantation and development. Studies have shown that abnormalities in the number and morphology of embryonic cells are associated with an increased risk of fetal arrest. Therefore, in the process of embryo culture, it is necessary to closely monitor the development of embryos and screen high-quality embryos for transfer in time to reduce the risk of fetal suspension.
In addition, embryo quality may also be affected during embryo freezing and thawing. Research shows that the speed of embryo freezing and the method of thawing may have adverse effects on embryo quality. Therefore, in the process of selecting and thawing frozen embryos, it is necessary to strictly control the operation technology to avoid unnecessary damage.
Auxiliary technology
The risk of IVF abortion is closely related to the selection and operation of auxiliary technology. Common auxiliary techniques include embryo biopsy and PGD/PGS screening. Embryo biopsy may damage the morphology and development of embryos, thus increasing the risk of fetal arrest. Therefore, when conducting embryo biopsy, it is necessary to select appropriate time and technology to ensure the safety and accuracy of the operation.
The application of PGD/PGS screening can help screen safe and healthy embryos and reduce the risk of embryo abnormalities and fetal suspension. However, this technology itself may bring certain risks and uncertainties. Therefore, when PGD/PGS screening is applied, risks and benefits need to be carefully evaluated to ensure scientific and reliable operation.
summary
The risk of IVF fetal arrest is closely related to the increase of the index. Factors such as treatment options, maternal age, embryo quality and assistive technology will affect the risk of fetal arrest. Therefore, in the process of IVF treatment, doctors need to consider these factors comprehensively according to the specific conditions of patients and develop personalized treatment plans to reduce the risk of fetal arrest.
