BACKGROUND The aim of this study was to analyze whether the length of controlled ovarian stimulation affects in vitro fertilization (IVF) cycle outcomes. METHODS This retrospective cohort study was performed at a private, university-affiliated fertility centre. We reviewed 1522 IVF cycles, comprising 979 long gonadotropin-releasing hormone (GnRH) agonist and 543 GnRH antagonist protocols. All subjects underwent controlled ovarian stimulation followed by fresh embryo transfer. Logistic… CONTINUE READING
