OBJECTIVE: To analyze the effect of a previous donor oocyte cycle on the outcome of subsequent attempts. DESIGN: Retrospective study. SETTING: Oocyte donation program at The New York Hospital/Cornell Medical Center. PATIENT(S): Two hundred sixty-seven patients undergoing 354 fresh cycles of oocyte donation. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Clinical outcomes were divided into groups based on the attempt number of each cycle for each patient. Results were calculated for each recipient cycle. RESULT(S): A clinical pregnancy rate of 56.2% and ongoing pregnancy/delivery rate per retrieval of 50.3% were noted. No statistically significant differences in clinical outcomes were found between the first, second, and third attempts. A significant increase was noted in the ongoing pregnancy/delivery rate per recipient cycle for the second attempt in those patients who had a delivery after the first attempt compared with those who did not. CONCLUSION(S): We demonstrated an overall clinical pregnancy rate of 56.2% and an ongoing pregnancy/delivery rate of 50.3% per retrieval. Outcome for the second attempt was associated with success or failure during an initial attempt at oocyte donation.
