Comparison of plasma seminal L-carnitine concentrations in asthenozoospermic, tratozoospermic

The key role of L-carnitine in sperm metabolism is justified by high level of L-carnitine in epididymis fluid. In present study, plasma seminal L-carnitine concentrations in asthenozoospermic, oligozoospermic, tratozoospermic and necrozoospermic infertile men are compared. Semen analysis was performed according to World Health Organization guidelines. Sperm parameters included liquefaction, pH, volume, sperm count, motility, viability and normal morphology. The results showed that plasma seminal L- carnitine concentration in asthenozoospermic specimens was significantly lower than specimens which had high motility, (p<0.001). On the other hand, plasma seminal L-carnitine concentration in necrozoospermic specimens was significantly lower than specimens which had high viability, (p<0.001). Also, plasma seminal L-carnitine concentration in tratozoospermic specimens was significantly lower than specimens which had high normal morphology, (p<0.01). Plasma seminal L-carnitine concentration in oligozoospermic specimens was significantly lower than specimens which had high sperm count, (p<0.001). In conclusion, plasma seminal L-carnitine concentration in infertile men with low quality semen parameters supplementation is lower than men with normal semen quality. So, L-carnitine treatment could affect on men infertility.
