People Share The Most NSFW Facts They Know About The Human Body

I hate body facts. I'm sheepish.

How about Dinner First?

"Doctors will press on the penis glans while having one finger in the anus, if by pressing the gland the sphincter of the anus try to close, it means the reflex is still alive, it is sometimes used to check if theres any damage to the spinal cord after an accident."

Bad to Worse

"The most f**ked up human fact I know is: generally, during a kidney transplant, the old kidneys are not removed from the body, they are left inside after the transplant. There is actually a gentleman in the Netherlands who holds the world record for number of kidneys inside his body, which is currently 7."

"I’ll make it worse. The native kidneys shrivel up like raisins. So they’re just little beans hanging around uselessly once the transplant has been there awhile. They have such a complicated vascular system, it’s easier to leave them in — and it helps that they won’t take up too much room for long."

Quite a Load

"The average human poops close to 400lbs per year."

"My guess is it’s calculated by looking at throughput volume in sewage systems and dividing by the number of people in the service area using census data."

"Could also be a very long series of laborious collections from individuals, but I personally wouldn’t want to participate in that work (as the pooper OR the scientist). Now what would be really interesting if we did have individual-level data would be to examine the median, mode, range, error, etc. to determine if the average is 'normal' or skewed by a small percentage of insanely high-volume poopers."

Going Down

"Human vaginal secretions contain hyaluronic acid and squalene, which are both used in skincare for hydration and elasticity. Squalene is also produced in high amounts in shark liver, so vaginas and sharks have that in common."

Clots

"If you continue to have an erection for several hours, blood will start to clot and harden, which decreases oxygenated blood flow to the tissue and can cause ischemia in the penile tissue. If one has an erection for longer than 24 hrs, the chances of having Erectile Dysfunction afterwards are exponentially higher statistically, from my understanding."

Finding Room...

"Toddler's adult teeth are stored right under their eyes at some point."

"Can confirm. During my studies the first time we were shown a child x-ray and asked for diagnosis, everybody was freaking out that there is something seriously wrong (we didn't know it was a child). Turns out we were completely bamboozled and it was a healthy child. That day I learned where and when adult teeth develop during childhood."

Unsafe/Unclean

"There are traces of human fecal matter pretty much everywhere."

M-Test24

"Mythbusters did a test where they were trying to see if putting your toothbrush in the cupboard would keep it cleaner. They had controls in other rooms that they expected to stay 100% poop free, but every single one tested positive for poop. There is no escape, there is nowhere safe."

Let it Burn

"The stomach acid in humans is so strong it could eat through most metals. However we're protected because of the mucus lining our gut."
