Effects of melatonin administration on testicular redox status (a) MDA (b) SOD (c) Catalase (d) GSH (e) GPx (f) GST of pregabalin-exposed male Wistar rats. Data are expressed as mean ± standard deviation (n = 5). Bars carrying superscript a are statistically significant (p < 0.05) when compared to Ctrl; b are statistically significant (p < 0.05) when compared to Mel; c are statistically significant (p < 0.05) when compared to LD PG; d are statistically significant (p < 0.05) when compared to HD PG; e are statistically significant (p < 0.05) when compared to LD PG + Mel
