Well hi there julieTG
Yes, i thought people might be intrigued by the warm testes trick. I got the idea many years ago after hearing about some Egyptian doctor who had invented underwear that do this as a novel means of birth control. Then years later i came across how this works - that the ratio of testosterone/estrogen output of the testes is a function of temperature. So even before i started doing it i was pretty confident it would work. And it definitely has.
Take note - This practice does not prevent erections, but it definitely can change your semen so it's clear and watery - meaning you are likely infertile. I don't know if that's reversible.
