Table 1.

The relative weight of the right testis (g) in the control and the PNP-treated groups

Time (after PNP administration)		PNP (mg/kg b.w.)
	Control (PBS)	0.01 (low dose)	0.1 (mid dose)	1.0 (high dose)
0.5 month	0.32 ± 0.13	0.25 ± 0.07	0.54 ± 0.12	0.40 ± 0.13
1 month	1.18 ± 0.12	1.34 ± 0.17	1.45 ± 0.20	1.16 ± 0.22
1.5 months	1.44 ± 0.08	1.54 ± 0.08	1.27 ± 0.17	1.46 ± 0.12
2 months	1.74 ± 0.08	1.49 ± 0.06	1.30 ± 0.05*	1.41 ± 0.07*
2.5 months	1.43 ± 0.17	1.31 ± 0.11	1.53 ± 0.15	1.33 ± 0.16

Each value represents the mean ± SEM of (n = 5) quails per group
