|Exposure duration||continuous for 4 h|
|Distance between exposed object and exposure source||3 cm|
|Setup||400 µl sperm suspension sample placed in 35 mm x 10 mm Petri dish, covered with 3 ml of embryo oil (to avoid evaporation); placed under a laptop computer connected via WiFi to the internet; computer worked actively uploading and downloading information; temperature kept constant at 25°C|
|Sham exposure||A sham exposure was conducted.|
Exposed sperm samples showed a significant decrease in progressive sperm motility and an increase in DNA fragmentation. Levels of dead sperms showed no significant differences between the two groups.
The authors speculate that keeping a laptop connected wirelessly to the internet on the lap near the testes may result in decreased male fertility.
