[Toxicity of nanoparticles on reproduction]

Nanoparticles (NPs) are sized between 1 and 100nm. Their size allows new nanoscale properties of particular interest for industrial and scientific purpose. Over the past twenty years, nanotechnology conquered many areas of use (electronic, cosmetic, textile…). While, human is exposed to an increasing number of nanoparticles sources, health impacts and, particularly on reproductive function, remains poorly evaluated. Indeed, traceability of nanoparticles use is lacking and nanotoxicology follows different rules than classical toxicology. This review focuses on the impact of NPs on health and particularly on fertility and addresses potential risks of chronic exposure to NPs on human fertility.
