Cumulative live births and predictive factors of emergency oocyte cryopreservation: a retrospective cohort study
Emergency oocyte vitrification yielded a cumulative live birth rate of 29.2%, with rates differing by clinical indication: 39.5% in the absolute male factor group and 11.8% in the relative male factor group. Moreover, the factors associated with reduced live birth rates differed depending on the underlying indication for vitrification. These findings support the clinical utility of emergency oocyte vitrification and underscore the significant contributions of both female and male factors to reproductive outcomes of oocyte cryopreservation.
