Sperm quality was evaluated according to WHO criteria (volume, liquefaction time, pH, viscosity, sperm count, total motility, progressive motility, cell viability and percentage of normal morphology).
|Group 1||daily mobile phone use: < 30 min|
|Group 2||daily mobile phone use: 30 min - 2 h|
|Group 3||daily mobile phone use: > 2 h|
|Group 4||daily wireless internet use: < 30 min|
|Group 5||daily wireless internet use: 30 min - 2 h|
|Group 6||daily wireless internet use: > 2 h|
|Group 7||internet use: wireless|
|Group 8||internet use: cable|
|Group 9||habits of carrying the mobile phone: in the trouser pocket|
|Group 10||habits of carrying the mobile phone: in the handbag|
|Group 11||habits of carrying the mobile phone: in the jacket pocket|
No significant difference in sperm quality was observed between the three groups with different durations of daily mobile phone use (groups 1-3) (remark EMF-Portal: contradictory statements regarding the significance of motility between abstract and table 1 as well as text in results and discussion on the other hand).
Differences in total and progressive sperm motility were found between the groups with different duration of internet use via WLAN (group 4-6) as well as between groups with wireless internet use and wired internet use (groups 7-8).
The carrying habits of the mobile phone had a significant effect on sperm morphology but not on other sperm parameters. The lowest percentage of sperms with normal morphology was found in Jacket pocket carriers followed by trousers pocket carriers and finally handbag carriers with the highest percentage of normal morphology.
