Does ghouls use pheromones to tell the difference between a human and a ghoul?

Since the ghoul´s sense of smell has been mentioned from time to time, then is it possible that part of the ghoul biology involves pheromones unique to ghouls to display their presence?

And the fact that the males could tell that Kaneki emitted the scent of a "female" ghoul (Rize) then would they be able to smell sex pheromones as well?

(Unless Kaneki been sniffed out as female by other female ghouls in the story and called on it (I don´t know if a female ghoul ever told him he smell of a female) then could the differences in scents perhaps be a hint on how ghouls finds partners that aren´t human...)

Example: "I smell a adrenaline pumped male ghoul nearby... Screw it, I´m out of here."

Example two: "I smell a hot female in the heat nearby... Screw it, I´ll be right there in minute."

So I can imagine some of the ghouls get quite confused when they stumble on Kaneki...

But if Tsukiyama´s initial reaction is to be believed, the pheromones are quite the "high" for a ghoul...

So is it plausible that the ghouls can tell the difference from each other by releasing pheromones unique to them and their genders in the air?
