Heated car seats can burn fatherhood chances
An optimal temperature of between 35 and 36 degree Celsius is needed to produce healthy sperm. This is one reason why the testicles hang outside the main part of the body.
To test whether heated car seats might be raising scrotal temperatures above this threshold,at the University of Giessen in Germany and his colleagues fitted temperature sensors to the scrotums of 30 healthy men, who then sat on a heated car seat for 90 minutes.
An hour in, and scrotal temperature had already risen to an average of 37.3 degree Celsius, with a maximum temperature in one man of 39.7 degree Celsius. Men who sat on unheated car seats reached an average scrotal temperature of just 36.7 degree Celsius, reports.
Although that”s only a slight increase due to the heated seats, Jung notes that it may nevertheless be enough to damage the sperm production process.
Sitting in a car for long periods of time, even without a heated seat, is already known to raise scrotal temperatures. And previous research suggests that couples take longer to conceive if the man drives for more than 3 hours a day.
The team did not test the effect of the heated seat on sperm quality or quantity.
Heated car seats could lower a man’s sperm count, scientists
Heated car seats raise tempratures to 37.3C
A study found that electric-generated heat emitted by some driver’s seats raises body temperature to a point that interferes with the production of healthy sperm.
It follows the news that men who sit in a car for more than three hours a day, or who work as long distance lorry drivers or long-haul pilots, could be putting their fertility at risk.
The ideal temperature for sperm production is around 35C, just below the average core body temperature.
But if men wear tight fitting underwear or trousers, have long hot baths or spend too long sitting down the temperature rises.
Some experts believe changes in fashion and lifestyles are partly to blame for falling fertility rates.
Scientists from the University of Giessen, Germany, fitted temperature sensors to 30 healthy volunteers who than sat on a car seat fitted with a warmer for 90 minutes.
Within an hour, temperatures had risen to an average of 37.3C, a level at which sperm count is damaged, New Scientist magazine reported.
Sitting on an unheated car seat led to slightly raised temperatures of around 36.7C.
While the researchers did not test the quality or quantity of sperm, they say the effects of car seat heaters pose a greater risk to fertility than merely sitting for long periods.
Researchers in Holland compared the sperm counts of men who wore tight-fitting underpants for six months with those who wore loose garments and found that it fell.
