According to the researchers from Argentina a laptop with WiFi may cause the damage of sperms. A test was done by putting a drops of healthy sperm near a laptop downloading a data. After an hours the sperms where stopped swimming compared to the sperms placed away from the computer.In relation to these, a DNA near a laptop was damage three times to the sample control away from the device.
The main reason for this is the Electromagnetic radiation in the wireless devices. Another study conducted in US by making a test to the men working on laptops placing a temperature sensors on their scrotums. The result made the temperature rose to levels that can damage the production of sperm.
For maximum sperm production, testicles need to remain cool, even one to two degrees below body temperature. Using a laptop computer can cause temperatures to rise by 2.5°C in one hour, according to the study.
A remedy for this is to use a desk for placing your laptop.Or try a laptop pad and keep your legs apart, but men, this will only buy you 20 minutes before your testicles heat up to sperm-killing temperatures, according to the study's lead urologist Dr. Yefim Sheynkin of the University of New York at Stony Brook.
