What causes IVF abortion?
IVF is a method of assisted reproduction through in vitro fertilization (IVF) technology, which can help couples who are naturally difficult to conceive to realize their reproductive dreams. However, IVF also has a certain risk of abortion. IVF abortion refers to the phenomenon of spontaneous loss of embryos during pregnancy. The following will elaborate on the causes of IVF abortion from four aspects: hormone level, embryo quality, uterine problems and blood coagulation problems.
1. The hormone level is unstable
The instability of hormone levels is a major cause of IVF abortion. During IVF, patients usually need hormone therapy to promote ovarian ovulation and endometrial growth. However, sometimes the regulation of hormone levels does not fully meet the development needs of the fertilized egg, leading to the failure of the embryo to grow normally in the early pregnancy, leading to IVF abortion.
In addition, the instability of hormone levels may also lead to the inability of the endometrium to reach sufficient thickness, which makes it difficult to implant in the uterus. When the embryo cannot be firmly implanted, it is easy to miscarry. Therefore, stable hormone levels are essential for the maintenance of IVF pregnancy.
2. Embryo quality problems
Embryo quality is another important factor affecting IVF abortion. The quality of IVF embryos directly affects the growth and development of embryos during pregnancy. Some embryos with poor quality or chromosomal abnormalities are easy to lose naturally in early pregnancy, leading to IVF abortion.
Scientists have made great progress in embryo screening and detection, and can judge the quality of embryos through chromosome screening and gene detection. The risk of abortion can be greatly reduced by selecting high-quality embryos for transplantation.
3. Uterine problems
Uterine problems are also one of the common causes of IVF abortion. Uterine abnormalities such as hysteromyoma, endometrial polyps, adenomyosis, etc. may have a negative impact on embryo implantation and growth. In addition, abnormal shape or structure of the uterus may also lead to abnormal development of the embryo and abortion.
Some advanced hospitals provide uterine evaluation services before test tube babies, and conduct a comprehensive examination of the uterus through ultrasound, hysteroscopy and other technologies, so as to find and solve uterine problems in a timely manner.
4. Blood coagulation problem
Blood coagulation problems may also lead to IVF abortion. Some women with blood coagulation diseases, such as anti phospholipid antibody syndrome (APS), can easily coagulate blood, which will lead to insufficient oxygen supply for embryos, and eventually lead to abortion.
Testing the blood coagulation function and anticoagulant function can help doctors judge whether patients have blood coagulation problems, and take appropriate treatment measures to reduce the risk of IVF abortion.
summary
IVF abortion is the result of multiple factors. Unstable hormone levels, embryo quality problems, uterine problems and blood coagulation problems may all lead to IVF abortion. In order to reduce the risk of miscarriage, comprehensive evaluation and personalized treatment before IVF are very important. At the same time, the couple should actively cooperate with the doctor's guidance, maintain good living habits, pay attention to regulating emotions, and improve the success rate of pregnancy.
