patient questionnaire (Endometriosis Health Profile 5, EHP-5). The study will also be used to
describe the basic disease status and demographic characteristics of patients searching
treatment by a gynecologist because of their endometriosis. In addition, the study will give
insight into the typical diagnostic measures the physicians in different countries are using
