hi you need some kind of thermal ice bag with crushed ice inside it but cant think how it could be done but its going to give you a hell of a bulge that will attract comments. its an idea but cant think how and also to stop it leaking but it would keep your sack cool. needs some thinking. good luck
i need to keep my scrotum cold in order to fully recover from infection and inflammation on left testicle. how to do it? . left testicle had gotten stiff (not completely) and doubled its size and weight. doc said it'd take it up to 3 months to get back to normal but my country is too warm and that makes the sick testicle hang too low and that's delaying my recovery because i'll always inadvertently hurt the left testicle while sleeping trying to walk etc. so the 3 months passed it's only shrinked around 10%! so i was wondering if there is a way to keep my scrotum cold to make it stay retracted. thanks.
