I can't keep you from getting teh herp or any other STD, but I can help you avoid having to pay child support for 18 years. Go buy yourself one of those heated/vibrating back massagers for your truck.

I also suggest you wear "tighty-whities", they keep your junk nice and warm too (making it difficult for the little dudes to function).

Researchers Claim Heated Seats Can Cause Male Sterility


According to Drive, researchers in Germany have published a study linking the use of heated seats with a drop in fertility among men who use them for an hour or more at a time. Anecdotal evidence suggests that, just like in a jacuzzi, the extra heat raises the temperature of key equipment above its suggested operating range, causing potential damage to the finished product. Upon wider publication of the study, we feel it's safe to predict a surge in heated-seat popularity for men between the ages of 18 and 34.


Heated seats fry men's sperm: study, August 28, 2008


European researchers have found that heated seats could damage men's fertility.

Heated car seats bring relief in cold winter weather but new research suggests this luxury extra might be damaging men's chances of conceiving children.

Tests on German men have shown that the heated seats found in many European cars and new model Asian-designed vehicles raise scrotum temperature above optimal sperm production conditions.

Sperm-making is best at 35.5 degrees celsius, slightly below body temperature, explaining why the scrotum hangs outside the body.

But a study involving 30 men published in New Scientist magazine found heated seats raised the mercury of scrotums to 37.3 degrees after one hour of sitting, compared with 36.7 degrees on unheated seats.

One man's vital equipment reached 39.7 degrees, according to the study which was first published in the journal Fertility and Sterility.

Lead author Andreas Jung of the University of Giessen said although the increase was only slight it may nevertheless be enough to damage the sperm production process.

Professor Michael Chapman, a reproductive endocrinologist and fertility specialist in Sydney, said high temperatures had been shown to damage both the quality and quantity of sperm.

Men who work in hot environments like glass furnaces, as well as those who sit for long periods like truck drivers and taxi drivers, have been shown anecdotally to have lower sperm counts, Prof Chapman said.

"This increase seen with heated seats is unlikely to be a significant issue unless you are sitting in a car for a long period of time on a regular basis with the heater on," he said.

"But these are the types of things men should be considering if they want to have a baby but are having trouble conceiving."

Specialists now estimate 50 per cent of infertility troubles are due to sperm quality, with rates of sperm "breakage" increasing with age.

Prof Chapman said men concerned about the problem should "try wearing baggy underwear and getting out of your vehicle a few times during the day if you're a taxi driver or truck driver".
