Motility, n = 28 (%progressive) 48.4 ± 2.4 (17–71) 64.4 ± 3.8 (22–91) 67.9 ± 5.4 (0–97) 8.0 ± 2.6 (0–53)
  1. Values are means ± SEM (minimum-maximum values).
  2. All values are statistically significantly different when comparing DGC+MACS, DGC, raw samples (p < 0.05, paired t-test) except for the value of motility 67.9 compared to 64.4.
