Stage and localization of pelvic endometriosis and pain.

We analyzed the prevalence of dysmenorrhea, pelvic pain, and dyspareunia in relation to the disease stage in 160 women with endometriosis but no other associated pelvic disease who underwent their first gynecologic surgery (laparoscopy or laparotomy) at the First Obstetric and Gynecology Clinic of the University of Milan between 1985 and 1987. Dysmenorrhea was reported by 78% of the patients, pelvic pain by 39%; and deep dyspareunia by 32%. No relation was found between severity of the pain symptoms and stage of the disease or site of the endometriotic lesions.
