Percentages of TUNEL-positive spermatozoa, for each patient (P1-P6) and control (C1-C6). Chi2 results with p < 0.05 were considered as statistically significant

Patient	% of TUNEL-positive sperm	Control	% of TUNEL-positive sperm	p
P1	1.2 %	C1	1.8 %	NS
P2	12.3 %	C2	0.6 %	p < 0.001
P3	2 %	C3	0.8 %	NS
P4	4 %	C4	1.4 %	p < 0.001
P5	4.8 %	C5	1.8 %	p = 0.01
P6	4.4 %	C6	1.2 %	p < 0.001
