dc.description.abstractObjective: To report an emergency approach of random-start controlled ovarian hyperstimulation (COH) in the late follicular or luteal phase of the menstrual cycle for embryo cryopreservation in patients with cancer. Design: Case series. Setting: Academic tertiary referral centers. Patient(s): Three patients with a diagnosis of breast cancer requiring emergency fertility preservation in the late follicular or luteal phase of the menstrual cycle. Intervention(s): After baseline pelvic ultrasound and hormonal evaluation, random-start COH was commenced immediately on menstrual cycle days 11, 14, or 17 with use of letrozole 2.5 mg/d and recombinant FSH 150 to 300 IU/d. Gonadotropin-releasing hormone antagonist was administered to prevent ovulation in all cases. Ovulation was triggered with either 250 mu g of recombinant hCG or 10,000 IU of urinary hCG. Main Outcome Measure(s): Number of oocytes harvested, maturity and fertilization rates, number of embryos frozen. Result(s): Nine to 17 oocytes were harvested, resulting in the freezing of seven to 10 embryos with the mean maturity and fertilization rates of 58.8% to 77.7% and 69.2% to 87.5%, respectively. Conclusion(s): In an emergent setting, ovarian stimulation can be started at a random cycle date for the purpose of fertility preservation without compromising fertilization rates in letrozole cycles.
