Comparison of testes weight and serum testosterone concentrations in the control group and the groups treated by tamsulosin (n = 10)

Parameters Groups	Control (mean $\pm$ SD)	Experimental 1 (mean $\pm$ SD)	Experimental 2 (mean $\pm$ SD)	P-value
Testicle weight (gr)	1.00 $\pm$ 0.15	0.99 $\pm$ 0.15${}^b$	0.80 $\pm$ 0.10${}^a$	0.004
Testosterone (ng/ml)	1.05 $\pm$ 0.21	0.81 $\pm$ 0.09${}^c$	0.60 $\pm$ 0.10${}^b$	0.0001
LH (ng/ml)	0.194 $\pm$ 0.048	0.172 $\pm$ 0.051	0.155 $\pm$ 0.039	0.186
FSH (ng/ ml)	0.202 $\pm$ 0.048	0.254 $\pm$ 0.042	0.304 $\pm$ 0.057${}^a$	0.0001
Mean $\pm$ SD, one-way ANOVA, and post-hoc tests;${}^a$Significant between the control group and the experimental group 2; ${}^b$Significant between the experimental groups 1 and 2; ${}^c$Significant between the control group and the experimental group 1; Control: The group that received distilled water; Experimental 1: The group that received 0.2 mg/kg/day tamsulosin; and Experimental 2: The group that received 0.4 mg/ kg/day tamsulosin. LH: Luteinizing hormone; FSH: Follicle-stimulating hormone; SD: standard deviation
