Abstract

Objective: Cisplatin (CP) is a widely used chemotherapeutic agent, but its severe side effects impact testicular function. We investigated the potential protective effects of bilberry extract against CP-induced testicular toxicity.

Methods: Forty adult male albino rats were divided into four groups. Control animals received a single oral dose of 0.9% saline. Bilberry-treated rats received oral bilberry extract (200 mg/kg body weight [BW] dissolved in 1 mL of saline) daily for 10 consecutive days. CP-treated animals were administered a single intraperitoneal dose (7.5 mg/kg BW). Finally, a bilberry+CP group received oral bilberry extract (200 mg/kg BW) daily for 10 consecutive days, with one intraperitoneal dose of CP (7.5 mg/kg BW) on day 2. We assessed sperm count, motility, viability, and abnormalities, along with testis weight, testis weight-to-BW ratio, antioxidant activity, levels of oxidative stress markers (malondialdehyde [MDA] and hydrogen peroxide [H2O2]), sex hormones (follicle-stimulating hormone [FSH], luteinizing hormone [LH], and testosterone), and apoptotic and anti-apoptotic markers, and DNA damage. Testicular tissue underwent histopathological examination.

Results: Among CP-treated rats, significantly lower values were observed for testis weight; testis weight-to-BW ratio; levels of FSH, LH, testosterone, superoxide dismutase, catalase, glutathione S-transferase, glutathione, and B-cell lymphoma 2; and sperm count, motility, and proportion of normal sperm. CP administration was associated with higher MDA, H2O2, p53, Bax, cytochrome c, caspase 9, and caspase 3 levels, along with elevated tail moment. However, bilberry extract administration significantly improved all altered parameters.

Conclusion: Bilberry treatment demonstrated protective effects and reduced CP-induced testicular toxicity via antioxidant activity and cytoprotection.
