Sperm quality parameters in the presence of phloretin (PHL) at three different concentrations (250 μmol/L, 500 μmol/L and 1000 μmol/L) compared to samples exposed to extender alone. a Percentage of total motile spermatozoa (TMOT); b Percentage of viable sperm (SYBR-14+/PI−); c Superoxide levels (percentage of spermatozoa E+/YO-PRO-1−); d Peroxide levels (percentage of spermatozoa DCF+/PI−). Data were collected from fresh (extended) and frozen-thawed (FT) samples 30 and 240 min after thawing. Data reported as mean ± SEM. Different letters (a-c) indicate significant differences (P < 0.05) between treatments within a given time point
