What are the causes of fetal arrest and empty sac?

Embryo implantation and continuous development depend on the coordination of complex endocrine system. Any abnormal link can lead to abortion. During the early development of embryo, three important hormone levels are needed, one is estrogen, one is progesterone, and the other is human chorionic gonadotropin. As a mother, if her own endogenous hormone is insufficient, it can not meet the needs of the embryo, which may cause the embryo to stop breeding and abortion.

Intrauterine embryo or fetus is allogeneic transplantation, because the fetus is the combination of parents' genetic material, and it can not be exactly the same as the mother. Maternal fetal immune maladjustment causes maternal rejection of the fetus. The common autoimmune diseases are systemic lupus erythematosus, scleroderma, mixed connective tissue disease and dermatomyositis. The second is the problem of reproductive immunity. If we carry certain antibodies, it may affect the development of embryos.

The internal environment of the uterus and the overall environment of the uterus may have an impact on the embryo. The internal environment is the endometrium. If it is too thin or too thick, it will affect the implantation.
