Series of 55 pregnancies following ulipristal acetate treatment of symptomatic uterine fibroids

Introduction: Treatment with ulipristal acetate effectively controls excessive bleeding due to uterine fibroids and reduces their size. Uterine fibroid size reduction is expected to improve the results of the myomectomy and the reproductive prospects of the patient. Methods: Retrospective and descriptive analysis of a series of 53 patients who achieved pregnancy after being treated for symptomatic uterine fibroids. The primary endpoints were pregnancy and birth outcomes in women with symptomatic uterine fibroids that conceived following at least one course of therapy with ulipristal acetate 5 mg/day. The secondary endpoints were time until pregnancy, reasons for ulipristal acetate treatment, number of treatment courses completed, hemorrhagic control achievement, hemoglobin levels, fibroid FIGO classification, largest fibroid diameter, and type of myomectomy (if any). Results: Fifty-five pregnancies were registered in 53 patients following ulipristal acetate therapy (43 live births, 9 miscarriages, and 3 ongoing pregnancies). Half of the patients became pregnant without interval surgery. Bleeding control was achieved in 96% of the cases. A significant increase (p Conclusion: So far, this is the largest case series reporting both pregnancy and birth outcomes following ulipristal acetate therapy for uterine fibroids. Our data support favorable outcomes after therapy for this population subset.
