Watch Where You Put That Laptop, Guys

Consider this a public service announcement of sorts. Don't say I didn't warn you.

A Chicago fertility expert warns that, along with such activities as wearing briefs and soaking in the hot tub, laptop use may diminish sperm count. "Laptops are becoming increasingly common among young men wired into the latest technology," says Dr. Suzanne Kavic, director of the division of reproductive endocrinology at Loyola University Health System. "However, the heat generated from laptops can impact sperm production and development, making it difficult to conceive down the road." Kavic says when couples try unsuccessfully to conceive, males are the cause in 40 percent of cases.
