Semen parameter	Inter-rater agreement^a		Intra-rater agreement^b
Semen parameter	MSA (n=10)	X1 PRO (n=10)	MSA (n=10)	X1 PRO (n=10)
Concentration (10⁶/mL)	0.94	0.95	0.98	0.99
Total motility (%)	0.94	0.91	0.99	0.94
Progressive motility (%)	0.88	0.93	0.98	0.92

^aThree different operators were involved. ^bReadings were taken in triplicates.
