Figure 5. Sperm membrane lipid disorder evaluated through M540/YO-PRO-1 co-staining.

Figure 5

The figure shows percentages (mean±SEM) of viable spermatozoa with low membrane lipid disorder (M540−/YO-PRO-1) before and after freeze/thawing when sperm is stored at 17°C either for 3 h or for 24 h. Different superscripts (a, b, c, d, e) mean significant differences (P<0.05) among bars, each bar representing different holding times (3 h or 24 h), preservation (Ext vs. F-T) and post-thawing times (30 min or 240 min). Ext = Extended semen (17°C). FT-C = Frozen-thawed semen.
