They report changes in semen quality after 5 hours of exposure compared with control, including reduced sperm vitality at 1 cm and 10 cm distances.",

  "summary": "This in vitro study exposed live spermatozoa to emissions from a Wi‑Fi network active laptop at different distances and durations. The authors report reduced sperm activity and observed mortality, with reduced vitality compared with control after 2 and 5 hours of exposure. The paper concludes that laptop/device radiation may interfere with sperm fertilizing ability and advises caution with device use and distance.",
  "key_points": [
    "The study is an in vitro experiment using live spermatozoa exposed to a Wi‑Fi network active laptop.",
    "The authors report that sperm activity decreased and mortality was observed with exposure.",
    "Reported effects varied by exposure duration (2 h vs 5 h) and distance (1 cm vs 10 cm).",
    "The abstract reports reduced sperm vitality compared with control after exposure.",
    "The authors interpret the findings as potentially affecting fertilizable ability and fertility.",
    "Key exposure metrics (e.g., frequency, SAR) and sample size are not provided in the abstract."
