Patient experience with follitropin alfa prefilled pen versus previously used injectable gonadotropins for ovulation induction in oligoanovulatory women.

Objective: To evaluate patient satisfaction with the follitropin alfa prefilled pen (Gonal-f RFF Pen), compared with previously used injectable gonadotropins (vial/ampoules and syringe), in women undergoing ovulation induction (OI).

Research Design And Methods: Women aged 18-40 years undergoing OI for oligoanovulatory infertility were enrolled from nine US fertility centers in this prospective, open-label clinical trial. Participants received recombinant follitropin alfa using a prefilled pen.

Prospective, randomized trial comparing cetrorelix acetate and ganirelix acetate in a programmed, flexible protocol for premature luteinizing hormone surge prevention in assisted reproductive technologies.

Objective: To compare the safety and efficacy of single-dose cetrorelix acetate (3 mg) and daily ganirelix acetate (0.25 mg) in the inhibition of premature LH surge in women undergoing cycle-programmed ovarian stimulation before Assisted Reproductive Technology (ART).

Design: Prospective, open-label, randomized, comparative study.
