Possible causes of IVF abortion
IVF abortion refers to the termination of development or spontaneous death of embryos after pregnancy through assisted reproductive technology (such as IVF-IVF), resulting in pregnancy interruption. There are many reasons for IVF abortion, which will be described in detail in the following four aspects: embryonic factors, maternal factors, environmental factors and other factors.
Embryonic factor
Embryo factor is one of the main reasons for IVF abortion. There are certain risks in the process of embryo culture in vitro, including embryo chromosome abnormalities, embryo development obstruction, etc. Chromosome abnormality is one of the most common causes of spontaneous abortion of embryos. The common abnormalities include numerical abnormality, structural abnormality and functional abnormality. In addition, embryo development is also an important reason for abortion. The development obstruction may be caused by the quality problem of the fertilized egg and the maladjustment of the embryo to the culture environment.
Chromosome abnormalities and development obstacles are important embryonic factors in IVF abortion. The hospital will carry out embryo chromosome detection during IVF technical operation, and improve the quality of embryo development by optimizing the culture environment and other measures, so as to reduce the risk of abortion.
maternal factors
Maternal factors are also one of the important reasons for IVF abortion. Age is an important factor affecting the abortion rate of IVF babies. The older the female, the higher the risk of abortion. In addition, gynecological diseases such as thin endometrium, hysteromyoma and uterine malformation will also increase the risk of IVF abortion.
Before IVF, women should receive a comprehensive examination to understand their own reproductive health, and take appropriate treatment according to the doctor's recommendations. The hospital will take corresponding measures according to different causes, such as surgical treatment of uterine diseases, regulation of endocrine status, etc., to reduce the risk of abortion.
environmental factor
Environmental factors are one of the potential causes of IVF abortion. Environmental factors include living environment, working environment, social environment, etc. The study found that smoking, drinking, overwork and other bad habits were associated with the increased risk of IVF abortion. In addition, exposure to harmful substances, radiation and other environmental pollution may also have adverse effects on embryonic development and pregnancy stability.
Couples preparing for IVF should pay attention to improving their lifestyle and avoiding adverse environmental impacts. The hospital will remind the couple to pay attention to environmental protection and avoid contact with harmful substances during the operation of IVF, thus reducing the risk of abortion.
Other factors
In addition to the above embryo, maternal and environmental factors, there are other factors that may lead to IVF abortion. For example, the operation technology of assisted reproductive technology, drug application and other factors will also affect the abortion risk of IVF. In addition, pregnancy diseases, immune factors, coagulation dysfunction and other factors are also considered to cause IVF abortion.
The hospital will carry out training and quality control for operation technology, drug application and other issues to ensure standard and safe operation. For diseases during pregnancy and abnormal immune factors, the hospital will conduct comprehensive inspection and intervention treatment to reduce the risk of abortion.
Summary
There are many reasons for IVF abortion, including embryonic factors, maternal factors, environmental factors and other factors. Embryonic chromosomal abnormalities and development obstacles are the most common causes of embryonic factors; Age and uterine diseases are important factors in maternal factors; Smoking, drinking and environmental pollution are key factors in environmental factors; Operation technology, drug application, pregnancy diseases, etc. are other factors that need attention. By understanding and targeting these potential causes, intervention and treatment can reduce the risk of IVF abortion and improve the probability of successful pregnancy.
