PURPOSE: To identify treatment-related factors influencing low oocyte maturation rates in standard ovarian stimulation (OS) cycles and patients' candidates for clinical studies on rescue-IVM. METHODS: Retrospective study including retrievals with ≥ 1 cumulus-oocyte-complex (COC; years: 2008-2022). The weighted-mean immaturityrate (19%) was defined in the whole dataset (N = 16,155). Variables associated with...
