Interaction Between Decidual Cells and NK Cells in Endometriosis

Endometriosis is a chronic gynecological disease characterized by the presence of endometrial-like tissue outside the uterus and is frequently associated with pelvic pain and infertility. Increasing evidence suggests that immune dysfunction may contribute to the development and persistence of the disease. The purpose of this prospective case-control study is to compare immune cell characteristics in women with deep endometriosis and women without endometriosis during the secretory phase of the menstrual cycle. Participants will undergo collection of clinical data, blood samples, endometrial samples, and vaginal microbiota samples. For participants undergoing clinically indicated pelvic surgery, additional biological samples may be collected during the procedure. The study aims to improve understanding of the immune mechanisms involved in endometriosis and to identify potential biomarkers associated with the disease.
