EFFECT OF ZINC OXIDE NANOPARTICLES ON VIABILITY OF HUMAN SPERMATOZOA

摘要

Background: The extensive use of different nanoparticles has raised great concerns about their occupational and biological safety.Objective: The aim of this study was to evaluate the cytotoxic effect of zinc oxide nanoparticles (ZnO NPs) on viability of spermatozoa.Materials and Methods: Semen samples were obtained from 15 healthy persons, and were analyzed using WHO guidelines. Each semen sample was separately incubated with different concentrations of ZnO NPs (10, 100, 500, and 1000
