Introduction: To evaluate the association between endometrial polyp (EP) and inflammatory markers such as neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), monocyte/lymphocyte ratio (MLR) and plateletcrit (PCT).,Methods: In this retrospective and comparative case series, a total of 137 patients who had undergone endometrial biopsy due to various causes were included. Forty-eight of these patients were diagnosed with EP and classified as the patient group. Eighty-nine patients were diagnosed with proliferative/secretory endometrium and classified as the control group. The groups' PCT, NLR, PLR and MLR values were compared as statistically.,Results: There was no significant difference between the EP and control groups in terms of the NLR, PLR and MLR and the PCT value.,Conclusion: This is the first study in the literature evaluating the relationship between NLR, PLR and MLR and PCT value and EP. Further large-scale studies are essential to determine the exact role of NLR, PLR and MLR and PCT value on EPs.
