Is the probability of IVF stopping high?
IVF is a baby born by implanting the fertilized egg into the mother's body after it has been cultured to a certain stage in vitro through assisted reproduction technology. This technology gives hope to couples who cannot conceive naturally, but whether IVF has a higher risk of fetal arrest than natural pregnancy has always been a concern. This article will give detailed answers from four aspects: genetic factors, maternal age, diseases and medical measures.
1. Genetic factors
Genetic factors are an important factor affecting the termination of IVF. Some couples may carry genetic defects such as chromosome aberration or gene mutation, which increases the risk of embryo termination. In addition, some normal embryos may be damaged or lost in the process of artificial fertilization due to operational techniques or laboratory conditions.
In addition, the quality of fertilized eggs is also a key genetic factor. The quality of the fertilized egg depends on the quality of the sperm and egg and the chromosome combination when they are combined. If the quality of the fertilized eggs is poor, the embryo development may be abnormal, which may easily lead to embryo implantation failure or fetal arrest.
However, with the continuous development of modern assisted reproductive technology, the risk of fetal arrest caused by some genetic factors has been successfully reduced by selecting fertilized eggs with good embryonic quality for transplantation.
2. Maternal age
The maternal age of IVF infants is also an important factor in the risk of fetal arrest. With the increase of age, the number and quality of female eggs will decline, increasing the risk of abnormal embryonic development and fetal arrest, especially for women over 40 years old. This is because women's eggs are fixed at birth. As they grow older, exposure to various environmental and internal and external factors will lead to chromosomal abnormalities, increasing the possibility of embryonic dysplasia and fetal arrest.
However, the progress of modern medical technology enables older women to successfully conceive through IVF technology. Doctors will assess the potential risks according to women's age and health status, and take corresponding preventive measures, such as selecting more suitable fertilized eggs, to improve the success rate.
3. Disease
Some diseases also increase the risk of IVF fetal arrest. For example, gynecological diseases such as endometriosis and polycystic ovary syndrome may lead to ovarian dysfunction, abnormal egg development or unsuitable intrauterine environment for embryo implantation, which increases the possibility of fetal arrest. At the same time, some metabolic diseases, such as hypertension and diabetes, will also affect embryonic development and fetal health, increasing the risk of fetal arrest.
However, in the process of IVF, doctors will conduct a comprehensive physical examination and assessment in advance for these couples with potential disease risks, and give targeted treatment or adjustment to minimize the risk of fetal suspension.
4. Medical measures
In the process of IVF, medical measures are also an important factor affecting the probability of fetal arrest. For example, in the process of embryo transfer, whether the operation technology is skilled and the operation process is standardized will play an important role in the successful insertion of embryos into the uterine wall. In addition, the drug treatment program also needs accurate calculation and reasonable adjustment to ensure the healthy development and smooth implantation of embryos.
During the whole IVF cycle, doctors and technicians will strictly control environmental factors to reduce interference to embryonic growth. The professional level and rigorous operation of the medical team can significantly reduce the probability of tire stoppage.
Summary
In conclusion, the risk of IVF fetal arrest is closely related to genetic factors, maternal age, diseases and medical measures. Although there are certain risks in IVF compared with natural pregnancy, with the continuous progress of medical technology, IVF is still a viable option for couples with infertility problems. By selecting healthy fertilized eggs, evaluating and treating potential diseases in advance, and strictly controlling the medical process, we can effectively reduce the risk of IVF abortion and improve the success rate.
