Fig. 1From: Aquaglyceroporins but not orthodox aquaporins are involved in the cryotolerance of pig spermatozoaSperm quality parameters in the presence of 1,3-propanediol (PDO) at three different concentrations (0.1 mmol/L, 1 mmol/L and 10 mmol/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 pointBack to article page
