Protective effects of quercetin against testis damage caused by cisplatin

Abstract

We investigated the effects of quercetin on cisplatin induced testicular toxicity using histopathological, immunohistochemical and biochemical methods. We used four groups of Wistar albino male: control, quercetin, cisplatin, cisplatin + quercetin. We measured tissue malondialdehyde (MDA) and catalase (CAT) biochemically. We assessed apoptosis as indicated by P63 immunoreactivity. Testis tissues of the control group exhibited normal histology. In the cisplatin group, the diameter of the seminiferous tubule and thickness of the germinal epithelium were decreased compared to the control group. In the cisplatin group, degeneration of the germinal epithelium, cell separation from the basal membrane, giant cell formation, cell loss, atrophy and vacuolization were observed in the seminiferous tubule. We found hyalinization around the seminiferous tubule, intertubule hyalinization and perivascular fibrosis. In the cisplatin + quercetin group, we found that quercetin decreased atrophy, giant cell formation and vacuolization significantly. We found that quercetin exhibited ameliorative effects following cisplatin induced testicular damage.
