The incidence of ovarian torsion is high in patients receiving ovarian hyperstimulation due to enlarged ovaries, and ovarian hyperstimulation syndrome (OHSS) also facilitates the occurrence of ovarian torsion. Furthermore, intense exercise and body movement may increase the risk of ovarian torsion. Case Report: Herein, the case of a patient with ovarian torsion after ovarian hyperstimulation is reported here. This ovarian torsion may have been related to the vibration caused when she rode a motorcycle for an entire day on her holiday, 3 days after transvaginal oocyte retrieval. Conclusion: Ovarian torsion is a rare but severe complication in patients receiving assisted reproductive technology (ART), and emergent surgery with conservative treatment is recommended for final diagnosis and management. Exercise and vibration, which may increase the risk of torsion, should be considered as a risk factor for ovarian torsion, particularly in patients receiving ovarian hyperstimulation.
