PURPOSE: Previous reports have suggested that the ovarian response to leuprolide acetate is predictive of in vitro fertilization pregnancy rates. This study evaluated the outcome of in vitro fertilization cycles complicated by elevated estradiol levels during leuprolide acetate down regulation and the outcome of subsequent cycles in the same patients.
METHODS: Two hundred fifty-two in vitro fertilization cycles were initiated utilizing leuprolide acetate down regulation beginning on cycle day 1.
RESULTS: Seventy-four of these cycles had an elevated estradiol level at the time of the baseline scan (28%). This group of patients had a higher maternal age, a higher cycle cancellation rate (27.5 vs 16.3%), and a high rate of recurrence on subsequent cycles (63%).
CONCLUSIONS: The pregnancy rate per retrieval was equivalent in the two groups. This suggests that patients with advanced maternal age or a history of failure to suppress in a previous cycle may benefit from alternate regimens of superovulation.
