Radiation can affect sperm motility and vitality, and cause DNA fragmentation. As an example, in one Argentinian study, scientists studied the effect of laptop Radio Frequency (RF) radiation and WiFi on human male sperm.

• 25% of the sperm was no longer active compared to 14% from sperm samples stored at the same temperature over the same time period and away from the source of EMF.
• 9% of the sperm showed DNA damage, 3 times the damage experienced by the comparison samples.
