The CE effect on the spermatogenesis index.

Parameters	Experimental Groups a
	Control (H2O)	CE 100 mg/kg bw/day	CE 500 mg/kg bw/day	CE 1000 mg/kg bw/day
Number of animals evaluated	10	10	10	10
Spermatogenesis index b	3.47 ± 0.02	3.49 ± 0.02 ns	3.71 ± 0.02 *	3.76 ± 0.02 **

^a—Male rats were orally treated with either H₂O (control) or CE (100, 500, or 1000 mg/kg bw/day) for 60 days; ^b—mean ± SE. * p  =  0.001, ** p = 0.002; ^ns—the differences between the CE-treated and control groups were not statistically significant.
