A randomized controlled trial of increasing recombinant follicle-stimulating hormone after initiating a gonadotropin-releasing hormone antagonist for in vitro fertilization-embryo transfer

The use of rFSH and a GnRH antagonist in good candidates for IVF resulted in outstanding implantation and pregnancy rates. Increasing the dose of rFSH after starting a GnRH antagonist does not alter the estradiol response or improve the implantation and pregnancy rates.
