- InterventionsOn Cycleday 2 and Cycleday 20 a gynaecological investigation, a transvaginal ultrasound and MRI will be performed. Also a bloodsample (serum Ca 125) will be collected. In case of a cystectomy also a pippelle from the endometrium will be taken.
- Primary outcomeThe difference in the amount of blood-stained peritoneal fluid measured by TVUS and MRI in women with endometriosis versus healthy controls.
- Secondary outcome1. The localisation and amount of resorption of blood stained peritoneal fluid;
2. The volume and aspect of endometrial cysts;
3. Signal intesity and thickness of the junctional zone in endometriosis patients and controls;
4. Apperent Diffusion coefficient (ADC) in endometrial cysts, myometrium and junctional zone.

- Brief summaryEndometriosis is defined as the presence of endometrial- like tissue (which is in normal circumstances only inside the uterus) within the pelvis and other extra-uterine sites. It is a common estrogen dependant disease which is thought to affect up to 10% of women of reproductive age. This can rise up to 35-50% in women presenting with pelvic pain and infertility or both. The etiology remains unclear. Sampson described the theory of menstruation in 1927. This theory describes the backflow of menstrual fluid from the uterine cavity through the tubes to the peritoneal cavity. In this study we will test this theory with modern imaging techniques (TVUS and MRI).
