Percentages of motile sperm after incubation with Mn2+/Ca2+ (A) or Mg2+/Ca2+ (B) at different concentrations (0 mM, 0.1 mM, 1 mM, 5 mM, 10 mM and 50 mM) and for different incubation times (0 min, 2 min, 10 min, 30 min, 60 min). Different letters indicate significant differences (P ≤ 0.05) between concentrations of Mn2+/Ca2+ (A) or Mg2+/Ca2+ (B) at a given time point. Differences between time points within a given concentration are not shown
