Does it increase the risk of cancer? Just below that are the testicles in men
Not the cancer risk, but there's the risk of becoming impotent (sterile) because of the hot air.
The risk is certainly increased, but as long as you don't have your laptop on your lap for several hours every day, nothing tragic should happen.
Sterile and impotent are two different things!
With the former, you only shoot with blank cartridges, with the latter, the cannon barrel can no longer be cleverly aligned.
The heat exposure can temporarily, i.e. Temporarily, become sterile. So putting the laptop on your lap is not a safe preventive measure.
No.
