Effect of L-carnitine (LC) on sperm maturity and sperm DNA quality of adult male Wistar rats in control and treated groups

Group	Control	L-carnitine	Diabetic	Diabetic + LC50	Diabetic + LC100	Diabetic + LC200
Sperm maturity (%)	85.58 ± 4.42	86.35 ± 5.45	64.43 ± 4.46${}^{\text{a}}$***	66.28 ± 3.22	71.48 ± 3.37	79.20 ± 8.72${}^{\text{b}}$***,${}^{\text{c}}$**
DNA integrity (%)	6.0 ± 1.78	5.66 ± 1.36	15.33 ± 1.86${}^{\text{a}}$***	14.50 ± 1.51	12.83 ± 1.47	10.67 ± 1.36${}^{\text{b}}$***,${}^{\text{c}}$**
The data are expressed as mean $\pm$ SD. Statistical significance is represented as follows: (**p $<$ 0.01, ***p $<$ 0.001) LC: L-carnitine ${}^{\text{a}}$: compared with control group; ${}^{\text{b}}$: compared with diabetic group; ${}^{\text{c}}$: compared doses of LC 200, 100 with LC50
