OBJECTIVE: The goal of this study was to investigate the potential protective effect of L-carnitine (20 mg/kg bw, 1/20 LD 50) against aluminum chloride (AlCl3) on the quality of the male rats’ testicles and sperm, as well as to determine whether or not the effects of AlCl3 could be counteracted by using L-carnitine as an antioxidant.
MATERIALS AND METHODS: Six groups of 36 adult male albino rats (n=6) were randomly formed. In Group I (Gp I), saline injection was given orally as a control. Group II (Gp II) was injected orally with 75 mg/kg body weight of L-carnitine. Group III (Gp III) was given a high dose of L-carnitine (150 mg/kg body weight) orally, while Group IV (G IV) was given a low dose of AlCl3 (20 mg/kg body weight). Group V (Gp V) was given an oral injection of AlCl3 (20 mg/kg) and L-carnitine (75 mg/kg body weight). Group VI (Gp VI) was given AlCl3 at a dose of 20 mg/kg and L-carnitine at a dose of 150 mg/kg body weight for 60 days. The reproductive capacity of each group was assessed. Thus, in addition to histopathological analysis and the comet assay to evaluate sperm DNA deterioration, final body weight, testicular weight change, and sperm analysis were carried out.
RESULTS: The findings revealed that AlCl3 caused a significant decrease in final body weight, relative weight of sex organs, sperm concentration, motility and viability, serum testosterone concentration, and a significant increase in sperm abnormalities. Furthermore, AlCl3 caused visible changes in the histological structure of the testis.
CONCLUSIONS: L-carnitine treatment alleviated the harmful effects of AlCl3, as evidenced histopathologically by a noticeable improvement in testis tissues. When it comes to treating AlCl3-induced reproductive toxicity in male rat testes, L-carnitine shows promise.
