The case for laptop computers kept on the lap when they&#x27;re hot having an effect on this clearer because they can heat up the groin and part of the reason there is a ball sack hanging out of the body is to keep them cooler than the rest of the body, so heating them up is not a good idea if you&#x27;re interested in getting a woman pregnant. This is not major worry though since apparently it is reversible if you stop using laptops this way. For a phone though unless it&#x27;s hot, harder to understand why this would cause this.<p>I like how the articles specifies men&#x27;s sperm as opposed to women&#x27;s sperm. Although that does bring up a point about whether someone should research the effect on corresponding female parts.
