Laptops might be a factor in men’s infertility
Tech joins smoking, obesity as culprits
Could technolSAN FRANCIS CO ogy make you infertile? The problem may be resting on your lap.
A study published last week shows sperm counts in western men have been falling for the last 40 years. There are some theories about why it’s happening — smoking, obesity and stress among the culprits — but scien- tists do not have a definitive answer.
The study cites another study from 2015 that shows an increase in scrotal temperature also can cause sperm to be abnormal in quantity and quality. When the scrotum heats up, the sperm that is produced can take on a different shape that is not as effective at penetrating the egg, lowering the chances of becoming pregnant.
There are multiple factors that could cause the scrotum to heat up, such as hot tubs or tight cloth- ing, but one that has created some discussion is laptop use.
Laptop computers are designed to be easily portable and used comfortably in any situation, particularly on the lap. However, if a male uses a laptop on his lap too frequently, it is possible that his scrotum’s temperature will increase.
Yefim Sheynkin, an associate professor of urology at Stony Brook University School of Medicine, published a study in 2005 that proved laptop use can cause the scrotum’s temperature to rise. It is not only about using the laptop on the lap, but the position the body is in when using the laptop. “We did find that scrotal temperature increased, and it increased significantly, in the men using laptop computers in the laptop position,” Sheynkin told USA TODAY. “The laptop computer potentially may impact fertility by increasing scrotal temperature.” The laptop position is sitting with the legs closed with the lap- top directly on the lap, trapping the heat produced in the groin area. However, while it has been proven that increased scrotum temperature can impact the quality and number of sperm, it has not been definitively proven that laptop use leads to infertility in men.
Joshua Hurwitz, a partner at Reproductive Medicine Associates of Connecticut, said it is reasonable to assume the heat from the laptop can cause infertility. “You should get up and walk around just for general health. No one should be gaming, no one should be coding for 12 hours a day,” Hurwitz said.
