Heated Car Seats are Frying Men’s Sperms

Posted by Alex in Car & Vehicle, Medicine on August 28, 2008 at 11:14 pm


Heated car seats are nice and toasty for your bottom, but it may prove be too toasty for men’s sperms:

Optimal sperm production requires a temperature 1 to 2 °C below
the core body temperature of 37 °C. 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, Andreas Jung 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 °C, with a maximum temperature in one man of 39.7 °C. [...] 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.

    It’s a good thing my seat heaters haven’t worked since I bought the Jeep. Then again, I did have that vasectomy, so…er, nevermind. Hope your move went well, but heard it didn’t!

    “…colleagues FITTED temperature sensors to the scrotums of 30 healthy men…”

    Sperms? I thought the plural was just “sperm”…

    I’ve heard the same thing can happen with disposable diapers and baby boys. Well, what do you expect if you encase the testicles in non-breathable plastic for 24 hours a day?

    I hear Scientologists are using car seat heaters to help eliminate body thetans, as well.

    I live in Southern California. I dont understand why nearly every car even has car seat heaters.

    Truthfully, it seems to me it would be better if the cars has seat coolers.
