Who of the guys puts it on their lap ?

Pasche said a much larger concern involves laptop heat emissions and ?a decrease in spermatogenesis,? or the production of healthy male sperm.
The issue was given considerable ink in 2004, when a U.S. study printed in the leading medical journal Human Reproduction said that laptop heat can raise scrotal temperatures up to five degrees, a significant difference.
The study found that ?significant but reversible changes? in sperm production resulted from short-term laptop use. However, using a laptop often day after day doesn?t give the body a chance to recover from heat exposures, and ?may cause irreversible or partially reversible changes in male reproductive function," the study said.
U.S. news outlets trumpeted the news, with headlines like ?Doctors warn young men: Get the laptop off your lap!?
However, a leading fertility doctor in Chicago isn?t overly concerned right now.
?I would view it as an anecdotal report,? said Dr. Edmond Confino.
Confino, who is reproductive endocrinologist and infertility doctor at Northwestern University?s Feinberg School of Medicine, said the knowledge that heat and infertility are connected goes back to Roman times (they noticed hot bath frequenters had trouble bearing children).
Men?s testicles are very temperature-sensitive ? they hang away from the main body to keep their temperature a few degrees cooler than the body?s ?core temperature.?
However, Confino said the study was far from authoritative, and he is still unsure if the heat from laptops is really enough to affect male sperm.
?It needs more work,? he said.
