Antioxidant Nanoparticles May Protect Male Fertility During Chemotherapy
A preclinical study published in Reproductive and Developmental Medicine found that combining melatonin with zinc oxide nanoparticles mitigates cyclophosphamide‑induced reproductive toxicity in male rats. The antioxidant duo restored testosterone and luteinizing hormone levels, lowered oxidative stress markers, and preserved spermatogenic cell populations. Researchers administered the treatments weekly for eight weeks across six experimental groups, demonstrating that the combined formulation outperformed either agent alone. The findings suggest a promising strategy to protect male fertility during chemotherapy, pending human trials.
