Titanium Dioxide Nanoparticles: Effects on Development and Male Reproductive System

The study on titanium dioxide nanoparticles (TiO2-NPs) using zebrafish as a model found that while TiO2-NPs did not affect embryonic development, they did alter the male reproductive system by increasing oxidative stress and affecting sex hormone regulation. TiO2-NPs accumulated in adult zebrafish organs, causing histological changes and potentially acting as endocrine disruptors with androgenic activity. The research highlights the need for further investigation into the environmental and health impacts of TiO2-NPs due to their potential reproductive toxicity.
