One theory is that men who use laptops on their laps could be at greater risk of testicular cancer because of the heat near the scrotum, which could damage cells. Some claim that such damage could potentially lead to skin cancer, but there is no evidence to prove this. Computers, like many other electrical appliances, produce electric and magnetic fields, however most are in the extremely low frequency range.
According to the World Health Organization, the field strengths are far below international exposure limit guidelines and there is no scientific evidence of health effects from long-term, low-level exposure. Even men keeping their knees together for prolonged periods can generate enough heat to decrease sperm viability, one study found. This makes an unfortunate scientific case for manspreading, but also suggests that the heat from laptops could pose a problem for fertility. Some research also suggests a link between laptops and scrotal hyperthermia risk, but these findings involved a small sample of men and were conducted in , before technological advances made laptop batteries cooler.
Although heat is a concern however minor that concern may be , experts generally agree that exposure to electromagnetic frequencies EMF from laptops is not. One study that suggested exposure to EMF decreased sperm motility and caused DNA fragmentation had poor methodology; other research claiming that exposure to cell phones caused significant drops in sperm motility failed to look at laptops specifically, and suffered from small sample size. Animal studies are similarly inconclusive.
