A doctor has explained how you can figure out the size of someone's penis and it doesn't involve getting out a tape measure or ruler (luckily). He reveals all here:
Dr Karan Rajan has parted with the information and referred to a scientific study to back up what he's saying.
Basically, and simply, you can estimate or measure the size of a man's penis by how short his index finger is in comparison to his ring finger.
In a video posted on to his TikTok channel @dr.karanr, he says: "You can guess the size of a man's cactus [TikTok safe work for penis] by how short his index finger is.
"According to a urological study in the Asian Journal of Andrology, a shorter index finger compared to ring finger correlates to a bigger schnozwangler."
Quick second to appreciate the word 'schnozwangler', please.
He goes on to add: "This is known as the second to fourth digit ratio, calculated by dividing the length of the index finger by the length of the ring finger.
"The smaller the index finger, the lower the 2D 4D ratio.
"A smaller digit ratio points to high exposure to testosterone in the uterus. According to the study testosterone doesn't just control future penis length but also future finger length."
Commenting on the TikTok video - which has been watched over 940,000 times - one person wrote: "While women are wondering if this is true, men are still watching and comparing their index and ring finger."
Another added: "I'll walk around with my hands in my pockets from now on..."
A third commented: "On todays episode of things I never wanted to know. Medicine studies some weird stuff..."
It might not be a 'rule' to live by though, unfortunately. As Dr Rajan explained: "This is not a HARD and fast rule, it's an interesting study but by no means a rule book! Love how this has triggered so many."
Lucky for us all, Dr Rajan is full of useful information. Not too long ago he explained why we hiccup and, more importantly, how we can really get rid of them.
There are all kinds of old wives' tales about this with suggestions including: drink water upside down, somehow scare the s*** out of yourself, or knock on at your neighbour's completely naked.
But why listen to the advice of an old wife when we've got TikTok Doc Karan? He proposed a number of methods.
He said: "Deep breathing - breathe in for five seconds, hold, and breathe out for five.
"Or you could imagine you're on a toilet trying to squeeze one out. You know, like holding your breath and bearing down?
"This is known as a Valsalva manoeuvre. If you've got a heart problem don't do this - that's how Elvis went out.
"Another Valsalva manoeuvre is gently pressing on your eyeballs - don't do it too hard."
There we have it, thanks doc.
