Yes, I believe that men's hormone levels fluctuate on a (roughly) monthly schedule and these fluctuations can affect mood. But the fact that they are calling this "PMS" is a fucking joke. Last I checked, men don't shed the lining of their reproductive organs, so how can they be pre-
menstrual?
They've done nothing in this particular study to show that this is a cyclical phenomenon. They just asked men and women a bunch of useless questions. They're clearly throwing around the term "PMS" to get attention from the masses. Fucking hacks.
