A significantly decreased fertilization rate (FR) was found for sperm exposed to 10(-5) M Ce, La and their combination, opposed to a significant increase of FR following 10(-7) and 10(-8) M REE sperm exposure. The offspring of REE-exposed sperm showed significantly increased developmental defects following sperm exposure to 10(-5) M REEs vs. untreated controls, while exposure to 10(-7) and 10(-8) M REEs resulted in significantly decreased rates of developmental defects. Both of observed effects-on sperm fertilization success and on offspring quality-were closely exerted by Ce or La or their combination.en10.1007/s00128-023-03701-zinfo:eu-repo/semantics/openAccessRare earth elementsFertilizationDevelopmental defectsTransmissible effectsHormesisRare-Earth-ElementsAnimal HealthHormesisGrowthPerformanceToxicityHormetic Effects of Cerium, Lanthanum and Their Combination at Sub-micromolar Concentrations in Sea Urchin SpermArticle1103WOS:0009508481000012-s2.0-8515031342436922429Q2Q3
