Use of laptop computers connected to
internet through Wi-Fi decreases human
sperm motility and increases sperm DNA
fragmentation.
Design
Prospective in vitro study.
Setting
Center for reproductive medicine.
Patient(s)
Semen samples from 29 healthy donors.
Intervention(s)
Motile sperm were selected by swim up. Each
sperm suspension was divided into two
aliquots. One sperm aliquot (experimental)
from each patient was exposed to an internet-
connected laptop by Wi-Fi for 4 hours,
whereas the second aliquot (unexposed) was
used as control, incubated under identical
conditions without being exposed to the
laptop.
Main Outcome Measure(s)
Evaluation of sperm motility, viability, and
DNA fragmentation.
Result(s)
Donor sperm samples, mostly
normozoospermic, exposed ex vivo during 4
hours to a wireless internet-connected laptop
showed a significant decrease in progressive
sperm motility and an increase in sperm DNA
fragmentation. Levels of dead sperm showed
no significant differences between the two
groups.
Conclusion(s)
To our knowledge, this is the first study to
evaluate the direct impact of laptop use on
human spermatozoa. Ex vivo exposure of
human spermatozoa to a wireless internet-
connected laptop decreased motility and
induced DNA fragmentation by a nonthermal
effect. We speculate that keeping a laptop
connected wirelessly to the internet on the lap
near the testes may result in decreased male
fertility. Further in vitro and in vivo studies are
needed to prove this contention.

Putting a laptop on a lap for long hours can also cause infertility cos d heat produced by d laptop can kill sperms..With or without wifi

True that!

I was just warning my brother about it and he was like, what do you mean? is it not called "laptop"? Naim i jus maintain. lol!
