Abstract | Introduction: The association between estrogen and hypercoagulability is well-established but little is known about coagulation dynamics during IVF. Our goal was to measure coagulation potential prior to, during, and following an IVF cycle and to investigate differences by conception outcome. Materials and methods: Patients undergoing IVF with fresh embryo transfer at a single academic center using oral contraceptive pills for cycle batching underwent evaluation of thrombin generation using the calibrated automated thrombogram at multiple points during the IVF cycle. Multiple thrombin generation parameters were compared across timepoints and by IVF cycle outcome using ANOVA repeated measures analysis. Results: Of the 17 patients included, 11 conceived. There was a significant increase in peak and total thrombin generation in the entire cohort between the pre-treatment natural follicular phase and following a short course of oral contraceptive pills used for cycle batching. Further increase in these parameters was seen at the time of oocyte retrieval. In the pre-treatment natural follicular phase, patients who conceived had lower peak thrombin generation. There were changes throughout the cycle for factors II, V, VIII, X, XI, XII, antithrombin, and tissue factor pathway inhibitor. Only Factor XI was distinguishable by conception status; values were lower at all visits in patients who conceived. Conclusion: Increases in coagulation potential are seen in patients undergoing IVF following a short course of oral contraceptive pills for cycle batching and continue during controlled ovarian hyperstimulation. Those who conceived were seen to have lower peak thrombin generation in the pre-treatment natural follicular phase. |
