Ovarian Hyperstimulation Syndrome in Spontaneous Pregnancy

Background: Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of supraphysiologic ovarian stimulation but infrequently has been described in spontaneous pregnancy. Aim: To present a case of a woman in spontaneous pregnancy complicated by OHSS. Results: A 32-year-old gravida 1, para 1 with spontaneous conception, was diagnosed with moderate OHSS at the 11th week of gestation and was managed conservatively. The woman delivered vaginally at term a health female infant. Conclusion: Although the ovarian hyper stimulation syndrome is characteristic for patients undergoing ovarian stimulation or assisted reproductive technologies it may also occur in spontaneous pregnancy. Multidisciplinary approach has to be taken in managing of those patients.
