Trying to Conceive, Laptops Can Hurt Your Chances

 

FGF Trying to Conceive, Laptops Can Hurt Your ChancesA new study shows that men who use their laptops on their laps have increased temperature in their testicles, which can seriously impact sperm quality and their ability to fertilize an egg. A man’s testicles are located away from the body so that sperm are maintained at a temperature a few degrees cooler than the body’s core temperature. Studies have shown that increasing scrotal temperature by just 1.8 degrees Fahrenheit can harm sperm.

A team of researchers led Yelim Sheynkin, M.D (State University of New York at Stony Brook) studied the effects of seating position and laptop use on scrotal temperature in 29 healthy male volunteers. They measured scrotal temperature as the men sat using their laptops  in a variety of positions:

  • with a laptop resting on a desk
  • with their knees together and laptops on their laps
  • with their knees together and laptops resting on lap pads on their knees
  • with their knees apart and the laptop on their laps
  • with their knees apart, a lap pad on their knees between their laps and the laptop

After 11 minutes, scrotal temperature increased by more than 1.5 degrees when the men sat with laptops on their laps without the use of a lap pad (left side from 0.96C to 2.31C, right side from 0.91C to 2.56C). Even with the use of a lap pad, scrotal temperature still rose to the same degree in just 14 minutes (left side from 0.69C to 2.18C, right side from 0.72C to 2.06C).

Scrotal temperature did go up less when the men sat with their knees apart, but the increase in temperature was still a cause for concern.  Within 28 minutes, the temperature on the left side rose from 0.66C to 1.41C, and on the right side from 0.62C to 1.47C even with the use of a lap pad.

The investigators concluded that (a) using a lap pad does not shield men sufficiently from scrotal hyperthermia (increased temperatures) and (b) the only way to minimize scrotal hyperthermia is in male laptop users is to make sure men sit with their legs apart and keep the amount of time they sit with the laptop on their laps very short.
