Narrative ReviewHuman2025
Do mobile phones and laptop computers really impact sperm?
Plain-language summary
This review set out to examine whether mobile phones and laptops, as sources of electromagnetic radiation and heat, might harm male fertility by affecting semen quality. It analyzed existing studies, including original research, systematic reviews, and meta-analyses, to weigh the evidence on how these devices impact sperm health. The findings were mixed, with some studies suggesting a negative effect but others showing no clear link, leaving the overall impact uncertain. The authors concluded that while the evidence is not definitive, men concerned about fertility may choose to limit exposure to these devices as a precaution.
