TNF and venous thromboembolism: The insertion of ENG implant during the immediate postpartum period was not associated with differences in lochia duration [175] or alteration in the maternal metabolism and hemostatic system (blood pressure, maternal, BMI, waist circumference, complete blood count, CRP, IL-6, TNF-alpha, lipid profile, fasting serum glucose) [176,177]; similarly, no increased rate of venous thromboembolism [178] or negative impact on bone turnover [179] were observed.
