Embryonic arrest is a phenomenon in which an embryo stops developing and eventually dies early in pregnancy. This is a common pregnancy complication and one of the leading causes of spontaneous abortion. Although the specific cause of embryonic infertility is not fully understood, research suggests that it may be related to several factors. 1. Chromosomal abnormalities: Chromosomal abnormalities are one of the main reasons for embryonic termination. Normal embryos should have a complete pair of chromosomes, but in some cases, embryos may have chromosomal deletions, duplications, or structural abnormalities. These chromosomal abnormalities can affect the normal development of the embryo and lead to embryonic cessation.

Maternal age: Maternal age is one of the important factors in embryonic termination. As women age, their egg quality decreases and the incidence of chromosomal abnormalities increases. Therefore, women over the age of 35 are more likely to have embryonic infertility. 3. Abnormal uterine structure: Abnormal uterine structure is also one of the reasons for embryonic termination. For example, diseases such as endometriosis and uterine fibroids can affect the normal growth of the endometrium, thereby affecting the implantation and development of the embryo. 4. Endocrine disorders: Endocrine disorders may also lead to embryonic cessation. For example, diseases such as thyroid dysfunction and polycystic ovary syndrome can cause abnormal levels of estrogen and progesterone, thereby affecting the development of the embryo. 5. Immune system abnormalities: Immune system abnormalities may also be one of the reasons for embryonic termination. Some autoimmune diseases, such as systemic lupus erythematosus, cause the immune system to attack the embryo, causing it to stop fertilization. In addition to the above factors, there are other factors that may affect the normal development of the embryo. For example, maternal diseases such as diabetes and hypertension, bad living habits such as smoking and drinking, and the use of certain drugs may have adverse effects on embryonic development. To prevent embryonic infertility, you first need to maintain good living habits, including quitting smoking and drinking, and avoiding overeating, etc. In addition, women with risk factors such as advanced age and chromosomal abnormalities can undergo relevant examinations before pregnancy and receive appropriate assisted reproductive technologies, such as in vitro fertilization. Overall, embryonic termination is a complex issue involving the interaction of multiple factors. While we still have much to learn, by understanding and preventing these potential risk factors, we can reduce the incidence of embryonic abortion and increase the chance of a successful pregnancy.
