The Lupron screening test: Tailoring the use of leuprolide acetate in ovarian stimulation for in vitro fertilization

Research output: Contribution to journalArticle

Abstract

Study Objective: To evaluate the prognostic and therapeutic value of a Lupron (leuprolide acetate; Tap Pharmaceuticals, North Chicago, IL) screening test before ovarian stimulation for in vitro fertilization (IVF). Design: Prospective. Setting: Outpatient IVF program. Patients: Eighty patients exhibited four early estradiol (E2) patterns. Patients with pattern A and B remained on a flare-up ovarian stimulation protocol. Patients with pattern C were randomized to three ovarian stimulation protocols. Patients with pattern D were treated with the flare-up protocol using a high pure follicle-stimulating hormone (FSH) dose. Results: Patterns A, B, C, and D occurred in 44%, 16%, 25%, and 15% of the patients, respectively. The E2 pattern recurred in 77% of subsequent IVF cycles. Pattern A and B patients achieved a 41% (23/56) and 22% (5/23) ongoing pregnancy rate (PR) per stimulated cycle. An early luteal phase Lupron protocol had the best ongoing PR per stimulated cycle (10/27, 37%) in patients with a pattern C response. Pattern D patients had a 20% (5/25) ongoing PR per stimulated cycle. Conclusion: The Lupron screening test allows prospective selection of stimulation protocols in ovulatory patients undergoing IVF. Early E2 patterns A and B should be treated with the flare-up protocol. Pattern C patients benefit from the luteal phase Lupron protocol and pattern D patients benefit from a high pure FSH flare-up protocol.
