"Quality of a man’s sperm depends on how intelligent he is, and vice versa"

I don't think people know what "depends" means anymore. Especially the "vice versa" part.

That means if you improve the quality of your sperm, as a direct consequence you will become more intelligent, which brings forward all kinds of interesting questions, such as do men really think with their balls?

Agreed. That title made wonder what kind of crazy set of working memory training experiments took place. And I don't even know how they would test things in the other direction...
