    Abstract:
    OBJECTIVE: To explore the protective effect of L-carnitine (LC) on the reproductive function of male rats with asthenospermia induced by ornidazole (ORN). METHODS: Forty male SD rats (200-230 g) were randomly divided into Groups A (control: 0.5% carboxymethylcellulose solution), B (medium-dose ORN: 400 mg/kg/d), C (medium-dose ORN + LC: ORN 400 mg/kg/d + LC 100 mg/kg/d), D (high-dose ORN: 800 mg/kg/d), and E (high-dose ORN + LC: ORN 800 mg/kg/d + LC 100 mg/kg/d). All the rats were treated via gastric gavage for 20 days consecutively, and then killed for the detection of sperm motility and the sperm count of the cauda epididymis. RESULTS: Compared with Group A, there was a significant decrease in sperm motility and sperm count in Groups B and D (P < 0.05), while Group C showed a significant increase in both the parameters as compared with B (P < 0.05), but with no significant difference from A (P > 0.05). Group E exhibited no obvious improvement in sperm motility and sperm count, with no difference from D (P > 0.05). CONCLUSION: L-carnitine can improve the sperm motility and sperm count of the male rats with ornidazole-induced asthenospermia.
