Protein levels of the proinflammatory cytokines IL-6 (a), IL-8 (b), and IL-12 (c); the anti-inflammatory cytokine IL-10 (d); the pro-inflammatory factors HIF-1α (e), TGF-β (f), and NF-kB (g); and TOSC values against peroxyl (h) and hydroxyl (i) radicals in follicular fluid (FF) samples from poor-quality (NTQ) and top-quality (TQ) embryos. The interleukins and pro-inflammatory factors were measured with commercial ELISA kits, while the antioxidant activity (TOSC vs. peroxyl and hydroxyl radicals) of FF samples was measured by chromatographic analysis. The data are reported as the mean values ± SD. Statistical analysis was performed by unpaired t-tests: #
p < 0.05, ##
p < 0.01, ###
p < 0.001 (TQ vs. NTQ).
