Having laptop on your lap will definitely impact your fertility?


One of the articles we found says

In women, the answer is almost certainly no. Since eggs are produced in the ovaries, which are inside a woman's body, heat from a laptop or other external source is not likely to be so intense that it raises your core body temperature enough to damage the ovaries and hurt egg production.

The answer for men is less clear. Sperm is produced in the testicles, which are in the scrotum. Because the scrotum is located outside of the body, it's more vulnerable to external heat than a woman's ovaries are. Research suggests that an increase in scrotal temperature may lower sperm production and possibly affect the ability of the sperm to fertilize an egg. That's why some fertility experts advise men to steer clear of hot tubs, saunas, hot baths, and briefs when they're trying to get a woman pregnant – they all generate extra heat around the testicles.

In a small study at the State University of New York at Stony Brook, fertility researchers found that men who sat with working laptops on their laps for an hour had an average increase in scrotal temperature of about 5 degrees Fahrenheit, or about 2.7 degrees Celsius. Although the researchers didn't check whether the temperature increase actually affected the men's sperm production, previous studies have shown that even an increase of 1 degree Celsius in scrotal temperature can affect the production of healthy sperm.

More research is needed before we can say that laptops definitely have a negative effect on male fertility. Still, while you're trying to conceive, it's always better to play it safe. The researchers who conducted the study recommend that men who want to be fathers should work with their laptop on a desk or table, rather than on their lap.


According to another research, it says


New research published in the Archives of Environmental and Occupational Health evaluated five commonly used laptops of different brands.

After measuring the EMF exposure produced, researchers found EMF values were within the guidelines put forth by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), but "considerably higher than the values recommended by 2 recent guidelines for computer monitors magnetic field emissions, MPR II (Swedish Board for Technical Accreditation) and TCO (Swedish Confederation of Professional Employees), and those considered risky for tumor development."

Further, they noted that the EMF values became alarmingly high when the laptop was used close to the body:

"When close to the body, the laptop induces currents that are within 34.2% to 49.8% ICNIRP recommendations, but not negligible, to the adult's body and to the fetus (in pregnant women).

On the contrary, the power supply induces strong intracorporal electric current densities in the fetus and in the adult subject, which are respectively 182-263% and 71-483% higher than ICNIRP 98 basic restriction recommended to prevent adverse health effects."

This led them to conclude:

"Laptop is paradoxically an improper site for the use of an LTC, which consequently should be renamed to not induce customers towards an improper use."

Even typing on a Laptop May Expose You to Unsafe Levels of EMFs

If you use your laptop on a desk, as opposed to your lap, does this mean you're safe? If you want to be sure your health is not at risk, not only should your laptop not be put on your lap, but you should not type on it either. As I explain below, I have used a gauss meter on many notebook computers, and found EMF levels higher than 100 milligauss on most of them; safe ranges are less than 0.3.  

About the Personal Experience with Laptops

I have used a 13-inch notebook for many years as I travel. It was a marvellous way to keep productive during my travels on a plane and as a passenger in a car. For some reason, it never occurred to me to measure the EMF radiation coming from the device. Recently I used a gauss meter on my notebook computer, and on those of a number of my staff.

I was shocked to find that the EMF levels were off the chart on the device and most readings were higher than 100 milligauss. Safe ranges are less than 0.3. I do still use my notebook computer, but needless to say, I have made some VERY serious adjustments to using it -- and I would strongly encourage you to do the same. Most of the radiation decreases about 2-3 inches away from the computer. So I have been using an external keyboard ever since I found out that the readings were so high. I never put the device on my lap unless there is a 1-foot cushion under the notebook, as that is about how far the field extends out.

If you don't believe me on this one I would strongly encourage you to get a gauss meter and measure your own notebook computer and see for yourself. Fortunately, my favourite gadget, the iPad, measures within acceptable ranges so I continue to use that without an external keyboard.

However, there are additional considerations on using a notebook computer, which I discuss below.

Why Your Reproductive Health May be Especially at Risk

If you're a man who uses a laptop often, and you would like to have children in the future, or simply protect your reproductive health, consider this a warning … In the first study to evaluate the direct impact of laptop use on human sperm, published in the journal Fertility and Sterility, those exposed to a wireless internet-connected laptop showed a significant decrease in sperm motility and an increase in sperm DNA fragmentation. And this was after just four hours of exposure. Researchers concluded:

"We speculate that keeping a laptop connected wirelessly to the internet on the lap near the testes may result in decreased male fertility."

The culprit? Once again, it appears the electromagnetic radiation generated during use of wireless devices, similar to that generated during cell phone use, may have a devastating impact on your fertility.

Previous studies have found that laptop use may damage sperm through athermal effect, that is, by heating up the scrotum during use (this occurred even when a lap pad was used, most likely because the men's closed leg position, required to balance the laptop, also contributed to the heating effect). However, the current study found laptop use also leads to non-thermal adverse effects, which means even if you manage to avoid the heating effect, laptop use, on your lap, may still damage your fertility.

This is an area that deserves immediate and serious attention, considering the use of wireless technologies is growing at an exponential rate. And it's not only laptops that are the problem … According to a study published in Fertility and Sterility in 2008, statistically significant changes were found in men sperm count and health of the sperm based on cell phone use, too. Their conclusion? 

"Use of cell phones decreases the semen quality in men by decreasing the sperm count, motility, viability and normal morphology. The decrease in sperm parameters was dependent on the duration of daily exposure to cell phones, and independent of the initial semen quality."

One another research gives these following findings

Though more research is needed, using your laptop on your lap for long periods of time may affect your sperm quality and quantity. This is due to the heat the laptop generates. Testicles are more vulnerable to heat than ovaries, so women are unlikely to be affected in the same way. 

Research suggests that an increase in testicle temperature is closely linked to poor sperm quality and a temporary decrease in sperm production. Some fertility experts advise that while you're trying for a baby you should avoid using anything that could overheat your testicles.

This includes  heated waterbeds, saunas, electric blankets and spabaths.

In one study, men who had working laptops on their laps for an hour had an average increase in scrotal temperature of about 2.7 degrees C. But this was a small study and we can't say for certain that this has a negative effect on men's fertility. 

In addition, connecting to the internet using Wi-Fi while the laptop is on your lap may expose your testicles to radio-frequency electro-magnetic waves (RF-EMW). 

One study tested the effect on sperm outside of the human body. After four hours of exposure to Wi-Fi, sperm were less able to swim, and had changes in their genetic code (DNA). However this isn't enough evidence to prove that it will harm your fertility. 

The Final word

We saw quite a few view, opinions and research reports which all suggest that usage of laptop on our laps is definitely harmful so to play it safe while you’re trying to conceive, place your laptop on a desk or table when you use it, rather than on your lap.
