Abstract

Cisplatin is an effective chemotherapeutic drug used to treat many types of tumours. However, it may cause male reproductive toxicity. Gallic acid exhibits beneficial effects such as antioxidant, anti-inflammatory and antitumor. The current study investigated the beneficial effects of gallic acid against testis and epididymis toxicity induced by cisplatin. Male rats were divided into 4 groups as follows (n = 7): Control, cisplatin (a single dose of 8 mg/kg), Gallic acid (50 mg/kg) and cisplatin +Gallic acid groups. Testis was examined morphometrically by stereological methods. In addition, apoptosis, DNA damage, oxidative stress parameters in testis and testosterone in serum were measured. Epididymis was histopathologically evaluated. As a result, a significant decrease was observed in the number of spermatogonia, Leydig and Sertoli cells, testicular volume, height of germinal epithelial, Bcl-2 immunopositive cell number, activity of CAT, GSH and SOD enzymes and serum testosterone levels compared with the cisplatin group control group, while a significant increase was observed in the number of Caspase-3, Bax and 8-OHdG immunopositive cells and the MDA levels. However, Gallic acid significantly restored these parameters. Our study reveals that Gallic acid may improve Cisplatin-induced male reproductive toxicity by reducing oxidative stress, suppressing apoptosis and DNA damage and restoring structural and functional deterioration.
