Amifostine protective effect on cisplatin-treated rat testis

Area of Science:

• Reproductive toxicology
• Oncology
• Pharmacology

Background:

• Cisplatin is a crucial chemotherapy agent but induces significant testicular toxicity, including germ cell damage.
• Amifostine is recognized for its protective effects against radiation and chemotherapy-induced side effects.
• Understanding amifostine's role in mitigating cisplatin-induced testicular damage is vital for fertility preservation in cancer patients.

Purpose of the Study:

• To investigate the cytoprotective efficacy of amifostine against cisplatin-induced testicular damage in prepubertal rats.
• To evaluate the impact of amifostine on germ cell apoptosis, necrosis, and histological parameters following cisplatin exposure.

Main Methods:

• Prepubertal Wistar rats were administered cisplatin (5 mg/kg) with or without prior amifostine treatment.
• Testicular tissues were analyzed using histological, morphometric, and stereological methods.
• Apoptotic germ cells were quantified using the TUNEL assay, alongside scoring of abnormal nuclear morphology.

Main Results:

• Cisplatin treatment led to significant testicular damage, including reduced tubular diameter and increased interstitial tissue and lymphatic space volume, indicative of edema.
• Amifostine pre-treatment (ACE group) significantly reduced histological alterations compared to cisplatin-only treated rats (CE group).
• The numerical densities of apoptotic germ cells and germ cells with abnormal nuclear morphology were lower in the ACE group than in the CE group.

Conclusions:

• Amifostine demonstrates a partial protective effect on the rat seminiferous epithelium against cisplatin-induced toxicity.
• Pre-administration of amifostine can mitigate cisplatin-induced testicular damage and germ cell loss in prepubertal rats.
• These findings suggest amifostine as a potential therapeutic agent for preserving fertility during cisplatin-based chemotherapy.
