Description of intervention(s) / exposure
This is a randomised study comparing two different surgical techniques for ovarian endometriosis designed to assess the ability to maintain ovarian function and to prevent recurrence of ovarian disease in the 6 months following surgery. No such study has ever been performed, though both surgical techniques are widely used. It is possible that the results from this study will give good evidence as to the benefit and risks from each surgical technique and provide our female patients with good evidence for their capacity for reproduction in the future.
