Abstract:

Busulfan (Bus), is an alkylating agent widely used in chemotherapy which has been proven to possess toxic side effects on testicles. This study was carried out to compare the probable treatment effects of resveratrol (Res) or/and l-carnitine (Lca), as strong antioxidants, on the testicular tissue as well as on the level of sex hormones in busulfan-induced azoospermic rat models. A total of 78 adult male rats, were divided into six different experimental groups including: 1) Control; 2) Lca + Res; 3) BUS; 4) Bus + Lca; 5) BUS + Res and 6) Bus + Lca + Res. Busulfan was intraperitoneally administered in a single dose (10 mg/kg b.w), while resveratrol (20 mg/kg b.w/day) and l-carnitine (200 mg/kg b.w/day) were orally administered by gavage during 48 consecutive days to the rats. At the end of the experiment in all groups the level of LH, FSH, and testosterone were biochemically analyzed by ELISA and the testicular tissue evaluated histologically using stereological technique. Results showed that Lca or/and Res, increased the body and testis weight, the volume of the testis, interstitial tissue, germinal epithelium, and seminiferous tubule, the number of the different cells of germinal epithelium and the level of testosterone. On the other hand, Lca, Res and their combination decreased the concentration of LH and FSH compared to the group treated with Bus. In conclusion, these results suggested that l-carnitine or/and resveratrol treatment significantly attenuated busulfan -induced changes of the rat reproductive system led to the recovery of both testis and sperm parameters. However, co-administration of L-ca and Res was more effective than their individualtreatment. This combination may alleviate the side effects of alkylating drugs, such as busulfan and may be beneficial for spermatogenesis.
