Brief Summary

Endometriosis, one of the most common diseases of women during their reproductive period., may present a chronic disabling disease with major impact on women's life. Therapeutic options are limited and recurrence of disease symptoms is frequent. The current study investigates the quality of life and several risk factors for the development of endometriosis as well as satisfaction with medical support in a minimum of 600 women with different stages of endometriosis and the same number of control women matched for age (± 3 years) and nationality. To evaluate specific features of endometriosis-associated pain a second group of 100 women with chronic abdominal/pelvic pain not related to endometriosis is investigated. Recruitment takes place in different university clinics, and districts hospitals in Switzerland, Germany. And Austria. Control women i.e. women without any evidence for endometriosis presenting for annual routine gynaecological controls are collected at the same places. A composition of different internationally validated questionnaires as well as specific questions on dealing with endometriosis is used to collect information on the quality of life and potential risk factors for endometriosis. Questions on sexuality and partnership are also distributed to women's partners. All diagnosis of endometriosis and classification of ASRM (American Society for Reproductive Medicine) disease stages are based on woman's medical charts.
