Fig. 2From: Oocyte polarized light microscopy, assay of specific follicular fluid metabolites, and gene expression in cumulus cells as different approaches to predict fertilization efficiency after ICSIExtracellular LDH (a), Cu,Zn-superoxide dismutase (SOD) (b) and catalase (c) activities in the FF of the largest follicle of each patient. F group = patients whose oocyte was fertilized, nF group = patients whose oocyte was not. Measurements for each FF were performed in triplicate, and data are presented as means ± standard error of the means. F group versus corresponding nF group: *** p < 0.001Back to article page
