Therefore, the number of pregnancies, as well as potential disruptive factors identified during gestation—such as general conditions (infections, viral illnesses, gestational diabetes, hypertension, hypothyroidism, hemorrhages), administration of medications (antibiotics, non-steroidal anti-inflammatory drugs, hormonal therapies, antispasmodics), variations in thyroid hormones, vitamin D, serum calcium, fever, and other complications (blood group incompatibility, placenta previa, anemia)—did not show statistical significance (Table 4). The gene discussed is TG; the disease is hypothyroidism.
