Implantation and growth of endometriosis was determined by immune cell. There were several immunologic cells that promoting implantation and cell proliferation such as macrophages, Natural killer, lymphocyte and monocyte. Infected endometrioma was associated in women with revised American Society for Reproductive Medicine (ASRM) stage III-IV. Neutrophil lymphocyte ratio (NLR) was a simple systemic inflammation response markers. The sensitivity and spesificity CA-125 in predicting endometrioma was very low but it had been used to monitor the progress of endometriosis. Therefore, measuring mean in leucocyte, NLR, PLR and CA-125 level in infected endometrioma was necessary.
