Background: As assisted reproductive technologies become increasingly available to patients, more women with Müllerian agenesis may undergo ovarian stimulation and oocyte retrieval to have genetically-related offspring. The risk of ovarian torsion is increased in patients utilizing assisted reproductive technologies compared to patients who do not undergo these treatments.

Case: A 25-year-old G0 with Mayer-Rokitansky-Kuster-Hauser syndrome presented to the emergency room two days after oocyte retrieval with an acute abdomen. During laparoscopy, she was found to have torsion of her left ovary.

Summary and Conclusion: As more young women with Müllerian agenesis present for fertility treatment, this anatomically unique patient cohort may be at an especially high risk for ovarian torsion. Physicians should recognize this risk and counsel their patients on this risk when discussing fertility options in patients with Müllerian agenesis.
