Apparently the idiots pursuing this ludicrous exercise, never learned in biology class that the testes descend into the scrotum during puberty, because they function best when they are allowed to dump heat into the surroundings, and operate at a temperature cooler than ambient body temperature.
Still, if right wing fantasists want to destroy their sperm count and produce fewer offspring, we should encourage them to do so. Means we’ll have fewer of them to deal with in future fenerations.
