Findings: No oocytes were found during four ovum pickups (OPU), despite a satisfactory ovarian response to controlled ovarian hyperstimulation. After the first attempt failed in the fourth case, five eggs were retrieved, fertilized, and cleaved after cycle rescue with hCG.
Conclusions: Whenever oocytes are not aspirated during OPU due to a lack of hCG administration, the cycle may be rescued if 10,000 IU of hCG is injected immediately and OPU planned for 33-36 hr later.
