Laptop Computer Use May Affect Male Fertility

December 11, 2004|From Times Staff and Wire Reports

Scientists at Stony Brook University Hospital on Long Island have discovered that an hour of using a computer on the lap is enough to heat up a man's testes, and the 4.9-degree Fahrenheit increase may impair fertility, they reported in the journal Human Reproduction.

Further tests are necessary to determine just how much heat would be detrimental to sperm, they said, and the next step is to measure sperm count before and after laptop use. Nevertheless, said Dr. Yefim Sheynkin, he will add a new question to his medical evaluation when he sees patients dealing with infertility.
