If you’re reading this and thinking “what’s TikTok?” then congratulations, you’re officially not young anymore! For the uninitiated, it’s a social network full of iconic videos and memes from (mostly) gen-Zers.
According to Dr Kieran Kennedy, these people are either lying or convincing themselves that they can taste the soy sauce. He told Men's Health Australia:
The study (or any that have followed) hasn’t shown that any animal can actually ’taste’ via these receptors like we’d taste something from the mouth. There is no scientific or medical evidence to back up any claims that men (of any species) can actually taste things through their junk.
So while the fact that there might be taste receptors in the testicles is pretty damn interesting, it unfortunately doesn’t mean (at least unfortunately for TikTok soy sauce users) there’s any evidence they can actually taste things.
Why isn’t it working?
The key difference seems to be that people are confusing the scrotum with testicles. Testicles are kept inside the scrotum and while they can taste things, the skin on the scrotum can’t. So really there’s zero chance that the soy flavour is actually being picked up. Either that, or people could just be smelling the soy flavour. As IFL Science's James Felton points out, studies have shown over half of our sense of taste actually comes from smell.
Maybe people should try tasting the soy through their anus instead? Because that might (genuinely) produce actual results.
