 Rationale: Laparoscopic myomectomy is increasingly performed over laparotomic myomectomy, because of the many benefits for the patient in terms of pain, hospital stay and recovery. In order to increase the success rate of a laparoscopic procedure pre-treatment to decrease the volume might be beneficial. Gonadotropin-releasing hormone agonists GnRHa are used for this purpose with good results in terms of volume reduction, but sometimes resulting in loss of distinction of the right surgical planes. Ulipristal is a new pre-operative treatment option for symptomatic fibroids, which has demonstrated good results in terms of volume reduction. The effect on cleavage planes is unknown. This study is performed to evaluate if Ulipristal is as effective as GnRHa in terms of surgical outcome.
