Kiani M, Parto P., Effect of L-Carnitine on semen of adult NMRI mice injected prolonged Cimetidine, Onl J Vet Res., 22 (3):210-215, 2018. Cimetidine is given for stomach ulcers, but its prolonged use can affect the male reproductive system. We report effects of L-carnitine on semen from adult mice treated daily for 15 days with 100mg/kg cimetidine. Groups of 5 NMRI mice each were injected intraperitoneally (IP) with 100 mg/kg cimetidine, 100 mg/kg L- carnitine, or 100 mg/kg cimetidine with 100mg L- carnitine in phosphate buffered saline (PBS) daily for 15 days. Controls were injected 1ml/L PBS IP. Cimetidine caused a decrease (P≤0.05) in motility, viability and normal morphology, but did not affect sperm count. Compared with mice given only cimetidine, L- carnitine with cimetidine increased (P≤0.05) sperm count, motility, viability and normal morphology. Our findings suggest that L- carnitine prevented toxic effects of cimetidine in sperm of adult NMRI mice.
Key Words: Cimetidine, L-Carnitine, semen, mice.
