Group	Control	L-carnitine	Diabetic	Diabetic + LC50	Diabetic + LC100	Diabetic + LC200
STD (µm)	285.7 ± 15.81	287.5 ± 15.43	249.9 ± 10.86${}^{\text{a}}$***	251.5 ± 13.06	256.1 ± 12.34	10.94 ± 261.5${}^{\text{b}}$***,${}^{\text{c}}$**
EGH (µm)	92.10 ± 10.21	94.72 ± 10.10	54.10 ± 11.98${}^{\text{a}}$***	56.80 ± 11.37	59.80 ± 11.34	64.00 ± 14.29${}^{\text{b}}$***,${}^{\text{c}}$*
Johnson’s scores	9.19 ± 0.39	9.22 ± 0.53	6.06 ± 0.75${}^{\text{a}}$***	6.21 ± 0.70	7.39 ± 1.05${}^{\text{b}}$*	8.08 ± 0.83${}^{\text{b}}$***,${}^{\text{c}}$**
Note: The data are expressed as mean $\pm$ SD. Statistical significance is represented as follows: (*p $<$ 0.05, **p $<$ 0.01, ***p $<$ 0.001) ${}^{\text{a}}$: compared with control group; ${}^{\text{b}}$: compared with diabetic group; ${}^{\text{c}}$: compared doses of LC 200, 100 with LC50. STD: seminiferous tubule diameter; GEH: Germinal epithelium height; LC: L-carnitine
