Effects of CdCl₂ alone and in combination with letrozole (CdCl₂ + letrozole) on the body weight and absolute and relative testes weights of male mice

Groups	Body weight		TW	TW/BW ratio (mg/g)
	Initial BW	Final BW
Control	30.52 ± 0.41	35.97 ± 0.57	0.25 ± 0.01	0.68 ± 0.02
Cd (4 mg/kg)	30.99 ± 0.64	33.55 ± 0.53*	0.24 ± 0.01	0.73 ± 0.03
Cd + letrozole (4 + 0.25 mg/kg)	30.85 ± 0.21	34.89 ± 0.31#	0.25 ± 0.01	0.72 ± 0.03

BW Body weight, TW Testis weight. Means ± SEM of five animals in each group. Compared with control group, *p < 0.05; compared with the Cd group, #p < 0.05
