Introduction:
To report a case of ovarian torsion following ovarian hyperstimulation with subsequent detorsion and oocyte retrieval.
Case description:
The patient was diagnosed with torsion following acute onset abdominal pain following her leuprolide acetate trigger injection. The patient underwent diagnostic laparoscopy which confirmed right ovarian torsion. Following detorsion, the patient underwent oocyte retrieval as planned with 72 total oocytes and 70 mature oocytes retrieved. Thirty-six mature oocytes were cryopreserved; 34 were inseminated with conventional in vitro fertilization, of which 27 (79.4%) were fertilized. Sixteen blastocyst stage embryos were cryopreserved.
Discussion:
Ovarian torsion during ovarian hyperstimulation is a rare event, but consideration should be given to detorsion first, followed by oocyte retrieval. We demonstrate that mature oocytes can be retrieved even after temporary vascular compromise to the ovary with subsequent excellent fertilization and blastocyst conversion rates.
