Effect of vitamin C on histomorphometric changes of testis, epididymis, prostate, and seminal vesicle induced by acrylamide in rat.

Acrylamide (ACR) has adverse effects on the rat testis. This study aimed to assess the impact of ACR and vit C exposure on reproductive organs in rats. In this experimental study, 32 adult male rats were used. The animals were divided into 4 groups (n = 8): (1) control group, (2) ACR (10 mg/kg) group, (3) vit C (200 mg/kg), (4) ACR (10 mg/kg) + vit C (200 mg/kg) daily for 5 weeks by gavage. After the administration period, testis, prostate, seminal vesicle, and epididymis of animals are removed; after preparing tissue sections, the structural changes of the tissues are examined by stereology. Data were analyzed using one-way ANOVA followed by the Tukey test in SPSS software. A value of p ≤ 0.05 was considered significant. The testis weight, volume (mm3), and the mean Johnsen score showed a significant decrease in comparison with the control group and vit C-treated group. These parameters were increased in ACR + vit C group. The number of spermatogonia, spermatocyte, spermatid, and Sertoli and Leydig cells in ACR-treated group showed a significant decrease in comparison with the control and vit C-treated groups. The number of these cells was increased in the ACR + vit C group. Epithelium height and folding of prostate and seminal vesicle in the ACR-treated group were decreased. Epithelium lost its integrity. In the ACR + vit C group, histopathological changes were decreased. Seminal vesicle of ACR + vit C-treated group showed mild degeneration and rupture in epithelium integrity. The epididymis of ACR + vit C group also showed mild degeneration and rupture in epithelium integrity.
