Successful Oocyte Retrieval After Follicular Fluid Aspiration in Suspicious of Ovarian Torsion.

During controlled ovarian stimulation, a 34-year-old woman complained of right lower abdominal pain after the decision to retrieve oocytes. Ovarian torsion was suspected and confirmed, so aspiration of follicular fluid was performed prior to oocyte retrieval for volume reduction of the affected ovary. Two days after that, oocytes were successfully collected. Four months later, the frozen embryo was transferred and got pregnant. In conclusion, it is possible to perform volume reduction before ovum pick up (OPU), and also possible to become pregnant by embryo transfer afterward. This is the rare case report of follicular aspiration prior to oocyte retrieval.
