Classifying the causes of miscarriage into hypoxic damage (defective implantation and vascular damage) and other causes (chromosome disease syndromes of the embryo, immunological damage and inflammatory damage), it was found that miscarriages from hypoxic damage accounted for 88.24% in the study group versus 51.52% in the control group, and the difference was highly significant ( p = 0.01).
