I suspect you would find many women are mentally impaired during pregnancy, based on my anecdotal experience. The hormones screw up your brain.
But, of course, that's irrelevant, since the men who lost teeth in the OP's study weren't tested for cognition deficits the second they lost a teeth. It was an ex post facto observed link --- and they don't know why.
So my comment had lots of good sense in it, while yours had none.
