N2 - Background: Use of recombinant follicle stimulating hormone (rFSH) in a cartridge pen device offers obvious benefits for donor oocyte cycles including the administration of fewer and more patient-friendly injectable medications. Methods: In a University-based IVF program, a total of 98 oocyte donor cycles using rFSH either reconstituted or as a pen device given to 118 recipients (eight split cycles) were retrospectively reviewed. Following discontinuation of oral contraceptive, controlled ovarian hyperstimulation was begun using either reconstituted rFSH (n = 19) or rFSH with a cartridge pen device (n = 79) (150-300IU qd). GnRH-antagonists (Ganirelix, Organon) and an additional 75 IU of rFSH/day were begun when lead follicles were 13-14 mm in greatest diameter. The primary endpoints analyzed included cycle stimulation characteristics for each donor group and donor medication tolerance assessment with respect to each rFSH formulation, while secondary outcome measures included clinical pregnancy and implantation rates. Results: Oocyte donors using the pen required significantly less rFSH (2734 IU vs. 3276 IU, p < 0.05) and scored significantly higher medication tolerance scores (3.9 ± 0.4 vs. 3.1 ± 0.6, p < 0.05). No other differences in cycle stimulation for oocyte donors and clinical outcomes for recipients were seen including pregnancy rates (pen, 77% vs. reconstituted, 55%, p - NS) and clinical pregnancy rates (61 % vs. 45%, p - NS). However, significantly greater implantation rates (57% vs. 31%, p < 0.01) occurred in the pen group. Conclusion: Compared to reconstituted formulations, the pen device results in lower gonadotropin requirements and provides a simplified dosing method with better tolerance.
