Concentrations of selected antibacterial proteins in semen collected from the studied groups.

	Excellent Motility (n = 43)	High Motility (n = 40)	Acceptable Motility (n = 41)
Lysozyme [U/L]	3.76 (3.45; 4.02)	3.02 (2.55; 3.33) *EM	1.97 (1.48; 2.19) ***EM; ***HM
Lactoferrin [mg/100 mL]	11.20 (10.00; 12.80)	12.90 (11.55; 13.93)	13.55 (13.15; 14.53) **EM
PLPA2 [ng/mL]	0.87 (0.76; 0.90)	0.89 (0.79; 0.88)	0.99 (0.82; 1.19)

Values are represented as median (25th; 75th percentile). * p < 0.05; ** p < 0.01; *** p < 0.001. ^EM—versus excellent motility group; ^HM—versus high motility group. PLPA2—phospholipase A2.
