Then is it still a problem ? Well , it's a problem due to the heat related effects . And then people say , well , I don't actually feel the heat of the phone .

Um It's uh really interesting however , and there are more and more quality data coming out all the time . And I think going forward , we are going to see that indeed , there are some negative effects of smartphones related to both their radio frequency um transmission and the fact that they generate heat and in general heat is not good for biological tissues .

And then people say , well , I don't actually feel the heat of the phone . It doesn't get that warm , but the temperature effects of the phone it turns out are enough even under conditions in which people don't report it to be uncomfortably warm that it can change the temperature milieu of the testicle in ways that can diminish sperm quality . How much and how that relates to fertility and healthy pregnancy , not clear .

And so if any of you would like to peruse the data in this me meta analysis , they're quite good . This study looked at 18 studies that include 4200 and 80 samples , they were able to separate out the radio frequency versus the heat effects and they were able to eliminate this time of usage . Um , variable that previously we thought if you were exposed to a lot of um cell phone contact , that it was far worse than if you were exposed to a little bit .

Since what we're mainly talking about now are smartphones . We want to separate out the heat effects of smartphones from the EMFS related to the fact that they are Wi Fi smartphones or they're using cellar towers and Wi Fi one or the other a combination . Ok .
