The implicitly suggested volume measure might not be the wrong measure either since fertility depends on quite a few variables, several we don't even know about.
These unknowns are actually a bit concerning on their own since fertility has been falling rapidly, at least in most of the western hemisphere, and the cause is unknown.

At least it's several times bigger than European and USA consumption.
Citation required for what? The fact that they eat more soy?
Demonizing soy is just a fad. Like demonizing meat or dairy.
Most of USA and Europe eats female mammals like cows and chickens, are we going to make claims that female animal estrogen contained in that flesh makes men infertile? Seems like a much more probable cause than phytoestrogen from plants, not that I would be irresposible to make that argument without any evidence, as is the case for soy.
