Kind of a silly and "private" topic, but it sounded interesting
There's one company "Snowballs Underwear" that has cooling packets that go in their underwear that supposedly may help with male fertility (and/or may boost testosterone?)
(Again a personal note before linking to this that this is kind of a "private" topic for "mature readers": https://www.snowballsunderwear.com/)
It has some historical precedent as the site notes that Russian bodybuilders of the 70s and 80s experimented with this "natural" attempt to boost testosterone
Any men tried this or have thoughts on the topic?
Good for a laugh? Able to confer serious benefits?
