Abstract

Environ Int . 2025 May:199:109449. doi: 10.1016/j.envint.2025.109449. WHO SR4A Review Full Title: Corrigendum to "Effects of radiofrequency electromagnetic field (RF-EMF) exposure on male fertility: A systematic review of experimental studies on non-human mammals and human sperm in vitro" [Environ. Int. 185 (2024) 108509] Journal: Environment International Direct Link: pubmed.ncbi.nlm.nih.gov Protocol reference: pubmed.ncbi.nlm.nih.gov This review evaluated: 117 animal studies 10 human sperm in vitro studies Major Finding: Moderate certainty — upgraded to high certainty in a 2025 corrigendum for the key endpoint — that RF-EMF exposure in males causes: A significant reduction in pregnancy rate when exposed males are mated. This is critical. This is not a sperm-motility proxy. This is not an oxidative stress biomarker. This is a direct reproductive endpoint. It means paternal RF exposure reduced the ability to successfully impregnate females. Additional findings included: Low-to-moderate certainty for reduced sperm count Reduced sperm vitality Increased sperm DNA damage This is the “conundrum” review many researchers now reference: strong adverse reproductive findings — especially the pregnancy-rate reduction from male exposure — alongside cautious regulatory interpretation. It directly raises concern for: Germline integrity Fertility decline Potential offspring impact This review evaluated 117 animal studies and 10 human sperm in vitro studies. Major finding: moderate certainty—upgraded to high certainty in a 2025 corrigendum for the key endpoint—that RF-EMF exposure in males causes a significant reduction in pregnancy rate when exposed males are mated. Additional findings included low-to-moderate certainty for reduced sperm count, reduced sperm vitality, and increased sperm DNA damage. The pasted text notes this as a “conundrum” review with strong adverse reproductive findings (especially pregnancy-rate reduction) alongside cautious regulatory interpretation, raising concern for germline integrity, fertility decline, and potential offspring impact.
