Alternative theory: men think with their junk. OK, I'll see myself out...
In all seriousness, it'd be great to see a more thorough study here. I see so many confounding factors. Measuring intelligence is a tough one. Perhaps people more likely to score higher on intelligence tests come from a part of the world where higher sperm counts were selected for genetically. For example, how do sperm counts correlated with the number of cold vs hot days during an average year? Or humidity levels? Or circumcision traditions? Or average penis size? My point is that there are so many factors that go into calculating intelligence and at least to me it seems there are as many factors that affect sperm count that this correlation may be influenced by several other hidden variables.
