Summary of article contents:
Introduction
Cyclophosphamide (CP) is a widely used chemotherapeutic agent known for its effectiveness in treating various malignancies. However, it has significant side effects, particularly on reproductive health, leading to reproductive toxicity and infertility. The present study investigates the protective effects of Aquilaria malaccensis (AM), a traditional medicinal plant recognized for its high antioxidant properties, on sperm quality in male rats subjected to CP-induced toxicity.
Antioxidant Role of Aquilaria malaccensis
The study reveals that CP treatment resulted in diminished sperm quality characterized by reduced motility and increased abnormal morphology. The administration of AM extract significantly countered these effects, highlighting its potential as an antioxidant. Specifically, AM reduced the percentage of abnormal sperm and improved the overall sperm parameters. The protective effect of AM is attributed to its ability to scavenge free radicals generated by CP, thereby mitigating oxidative stress and preventing damage to sperm cells.
Conclusion
This research supports the hypothesis that Aquilaria malaccensis could be a valuable adjunct therapy for preventing reproductive toxicity associated with CP. It suggests that supplementation with AM may enhance sperm quality and offer a protective mechanism against oxidative stress induced by chemotherapy. Further studies are needed to elucidate the exact biochemical pathways involved and to validate these findings through larger sample sizes. Overall, AM demonstrates the potential as a therapeutic agent in safeguarding male reproductive health during CP treatment.
