Let’s go back in time a few years to a Reddit post from user “CappnPoopdeck” told in classic “rage comic” form. Apparently the good Cap’n took a pregnancy test as a joke and discovered something unusual.

While pregnancy tests aren’t generally considered good screening methods, they do provide readings for the hormone human chorionic gonadotropin, which is produced by pregnant women and also by some men with testicular tumors. There’s no substitute for regular self-examination and yearly visits to your doctor, but if you’ve got a spare stick laying around, why not pee on it? It can’t hurt!
