In a report in the medical journal "Fertility and Sterility," scientists from Argentina conducted an experiment, placing semen under a laptop. After four hours, 25 percent of the sperm were no longer swimming and nine percent showed significant DNA damage. The culprit? The report says the damage was caused by electromagnetic radiation generated during wireless communication and from the heat of the laptop.
“I think that is a stretch. Most men will not tolerate a hot laptop on their lap for very long. So in fact, there have been no studies to show that a laptop sitting on the lap cause infertility,” said urologist Dr. Andrew McCullough.
It is also a stretch to think fertility is affected by sitting in heated car seats, but high temperatures in the long term could.
"Evolution has taught us that there’s probably a better place for testicles to be: outside of the body where it is cooler. So anything that might increase the heat theoretically might contribute to male infertility," said Dr. McCullough.
While there has been no data proving laptops affect fertility, other proven data is that for 40 percent of couples who are not able to conceive, it is because of the male.
“It can be caused by low testosterone. It can be caused by anatomical issues such as extra veins that heat up the testes. Or it could be - we just don't know - it could be environmental,” said Dr. McCullough.
And if you're wondered about cell phones being carried in gentlemen's front pockets affecting infertility…
“Despite the controversy, there really have been no studies linking either cell phone or laptops to male factor infertility,” said Dr. McCullough.
