Abstract

PurposeEndometriosis is not only associated with infertility, it is also a common cause of pain in women, leading to work absenteeism and a reduced quality of life. The objective of this study was to confirm the increased peritoneal fluid (PF) concentration of several cytokines in endometriosis patients, to investigate their association with pain levels, and to identify new biological markers in the PF which are neurostimulatory and thus responsible for the appearance and severity of different types of pain.MethodsOur sample group included 111 patients with histologically confirmed endometriosis and 47 controls undergoing laparoscopy for reasons of abdominal pain or infertility. They rated their pain during menstruation, during sexual intercourse and general lower abdominal pain prior to undergoing surgery in our clinic using a visual analogue scale. During laparoscopy, PF was aspirated. Marker cytokine concentrations were measured by immunoassay and correlated to the Revised American Fertility Society (r...
