Protective Effect of L-Carnitine on the Sperm Parameters of Adult Mice Treated with Ciprofloxacin

The present study examined the gonadotoxic effects of ciprofloxacin antibiotics and protective effects of L-carnitine.
In this study, 20 NMRI mice were divided into four groups: control, ciprofloxacin, L-carnitine, L-carnitine-ciprofloxacin (each group included 5 animals). The control group received normal saline, the treatment group 1 received 12.5 mg/kg ciprofloxacin, the treatment group 2 received 100 mg/kg L- carnitine and the treatment group 3 received 100 mg/kg L- carnitine and 12.5 mg / kg ciprofloxacin simultaneously. All animals were treated by intraperitoneal administration for 15 days. Testis and epididymis were collected to evaluate sperm parameters (sperm count, motility, morphology and viability).
In the ciprofloxacin group, a significant decrease in sperm count, sperm viability, sperm motility, progressive sperm motility and normal sperm as well as a significant increase in rotating sperm motility, sperm without movement, head and tail abnormalities were observed (p≤0.05). A significant increase in sperm count, sperm survival, motility and progressive sperm motility, normal sperm and a significant decrease in rotating sperm motility, sperm without movement and head abnormalities in the L-carnitine-ciprofloxacin group were observed (p≤0.05); however, the reduction in tail abnormalities of sperm was not significant.
L-carnitine improves sperm parameters in the adult mice treated with ciprofloxacin.
