Studies have shown that laptops (which heat up), when placed on the lap of males for extended periods of time, have been shown to lower fertility. So does taking long hot water baths or being in a jacuzzi for too long.
Korean scientists did a study on rats where they bathed them in hot water for a number of weeks, and there was a reduction in testosterone levels… with a stronger effect in the older rats.
A man’s testicles are meant to be colder then their body temperature. That’s why in hot weather, your nuts drop far from your body, to keep cooler than your body.
Hot water, warm testicles = bad for testosterone… cold water, cold testicles = better for testosterone.
Recently, the University of California at San Francisco did a study where men were exposed to 30 minutes of “wet heat” (hot baths and such) a week. When the men cut this exposure out, their sperm count went up by 491%, and their sperm’s motility improved as well.
According to a study done in 1993 by the Thrombosis Research Institute in England, cold water showers actually increase testosterone production in men. Increased testosterone levels not only naturally boost a man’s libido and erection quality, but also his overall strength and energy level.
