Comparison of protocols efficacy in poor responders: differences in oocytes/embryos competence with different protocols, a retrospective study

摘要

At present, there is no agreement on poor ovarian response definition, and no definitive evidence that this prognosis can be changed by a specific protocol. Our data suggest that a flare-up protocol with a depot gonadotropin-releasing hormone (GnRH) agonist formulation gives higher total pregnancy and implantation rates than a GnRH antagonist, possibly by improving oocyte/embryo competence.
