Abstract

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. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
