Personally,I’d like to know why the men’s sperm counts are so low..maybe something to do with how their balls are spaced.
Interesting hypothesis. I'd advise you to propose a study and get a grant. The testing phase should be exciting, just how would one measure the spacing? (As a guy I naturally am curious....). :-)
Too tight underwear probably. That's why it's traditional boxers for me. Unless I'm wearing the kilt, then it's free and breezy.
