	Control	50 ppm	100 mg/kg body weight	50 ppm
		PS	PNP	PNP + PS
Sperm count (×107/g)	89.65 ± 4.49	90.25 ± 4.61	65.77 ± 4.68*	73.80 ± 9.14
Abnormal sperm (%)	2.10 ± 0.20	1.96 ± 0.18	2.87 ± 0.61	2.57 ± 0.45
Testosterone (ng/ml)	2.34 ± 0.10	2.60 ±0.16	1.82 ± 0.13*	2.20 ± 0.28

The values shown are the mean ± SEM of five animals per group.
