The severity of pelvic pain and the incidence of infertility are not related to the localization of the lesions or to the stage of the disease (Gruppo Ital-iano per lo Studio dell Endometriosi 2001), as categorized according to the revised American Fertility Society (r-AFS) guidelines (American Fertility Society 1985). In fact, the r-AFS classification system is inadequate to express the severity of the symptomatology because it does not reflect the disease in terms of cellular mass or activity.
