This wild tale has been circulating for several years now. The first clue to its questionable veracity is the variety of reported effects: Drinking Mountain Dew will shrink your testicles. Or decrease your sperm count. Or cause your penis to grow smaller. Well, whatever occurs, it only happens to guys, and it hits them below the belt, right? Sounds a lot like the early 1990s legend that claimed Tropical Fantasy soft drinks contained a "secret ingredient" to cause sterility in Black male drinkers, doesn't it? This rumor is primarily spread about PepsiCo's Mountain Dew soft drink, although it has also been told about Mello Yello (a Coca-Cola product which, though still available, has been supplanted by Surge). The key is the presence of a dye called Yellow No. 5 in these drinks (presumably in large quantities), a food coloring that allegedly has nasty effects on one's manhood. Yellow No. 5, also known as tartrazine, is an FD&C (approved for use in food, drugs, and cosmetics) coloring dye commonly used to give various foods (such as beverages, candy, and ice cream) a bright lemon yellow color. It has long been deemed safe by the Food and Drug Administration. It has also been in use since 1916, so if it were shrinking penises and testicles, we'd probably have heard something more than rumors about it by now. (The FDA's established acceptable daily intake [ADI] for tartrazine is 5.0 milligrams per kilogram of body weight per day, which is about .01 ounces for a 132-pound person.) Many other common food products contain Yellow No. 5 as well, so more than just Mountain Dew drinkers would notice the effect if it were real. (Soft drinks don't contain a significantly larger amount of Yellow No. 5 than other food products.) The FDA has required since 1979 that food and drugs containing Yellow No. 5 be labeled to indicate its presence (and the U.S. Department of Agriculture requires similar labeling for meat and poultry), but that requirement came about because tartrazine was found to be associated with a variety of allergic type reactions in sensitive people, not because it wreaked havoc with the male reproductive system. If you're male and drink a lot of Mountain Dew, you will notice one related but perfectly harmless side effect: quite a bit of yellow liquid will flow out of your penis. ---http://www.snopes.com/toxins/yellow.htm NOTE: My source is usually pretty reliable when it comes to such myths or "urban legends."

Mountain Dew does not make your penis smaller. Yellow 5, which is found in Mountain dew lowers your sperm count. Yellow 5 is found in a lot of red, orange, green or yellow dyed foods like M &Ms

I seariously doubt it does squat, lately i have been drinking alot of Mountain Dew and i don't see any change in my testies, scrotium, or penis

I DID SEE SOMETHING ON THE NEWS A FEW YEARS BACK WHERE THIS GUY HAD A REALLY SMALL PENIS AND HE HAD WENT TO THE DOCTOR ABOUT IT, AND AFTER RUNNING LOTS OF TEST IT WAS DETERMINED THAT HE HAD A SMALL PENIS FROM DRINKING ANY DRINKS WITH YELLOW 5 IN THEM. HE HAD BEEN DRINKING THESE DRINKS SINCE CHILDHOOD AND APPARENTLY PREVENTED HIS PENIS FROM GROWING.

i dont think so why do u have a small one is that why your asking

There's probably some truth to it, but not because of chemicals or poisons. If you drink plenty of any soft drinks, you get a big belly which will cause the skin to "encroach" upon the share of skin your organ claimed. The same probably goes for beer, fast-food, and a sedentary lifestyle.

of course not! ron jeremy is a known endorser of this product! Mountain Dew does not cause "small penile syndrome, rather is has been linked to hairy back syndrome.....at least thats what I heard.....

I heard it makes you vote republican.

I wouldn't think so, although when my partner and i were trying to conceive a child, i found information suggesting "Mountain Dew" had an effect on male sperm counts. They stated when testing mens sperm count, over a few months on the study, there was a significant drop in all the males sperm, along with other products. This was one i remembered because my husband drinks it.

no it does not it does however lower your sperm count

I reckon if you went up a mountain to drink the dew you penis might get smaller - but that would have more to do with the temperature dropping the higher you went ;0)

Not if you mix it with Jack Daniel's! ;-)

I think this question is similar to "Do you smoke after sex"? In either case I can say I have not looked!

Not true in my case (according to my wife)! And I drink alot of Mtn. Dew!!

O yes. The same as you were actually not born but bought in walmart. Gravity is a figment of your imagination. Area 51 is full of UFO's.

Mountain dew no mountain dew does not make you smaller drinking accesive amounts of cafein however can . Why you might ask because cafein has been known to shrink blood vessels decreasing blood flow to muscles . You're penis or dick whatever you call it would only recieve a shrinkage if you drank an excessive amount of it .

no but lots of cavities !

yes dont drink it unless you want a wee-we the size of a pen cap,

if that were true then my bf's would be microscopic. not only has he been drinking Mt Dew for as long as he can remember he drinks about 3 to 5 a day. and i can tell you it is not microscopic in the least.

No, my boyfriend drinks alot of it and trust me there is no truth in that rumor!!!! +5

no

Maybe they shouldn't spend so much time reading labels.lol😈

how much moutian dew can you drink? 1 can a week wont hurt you. Stop listening to liars. If you drink 10 cans of any soft drink a day you will have problems.

Apparently coffee does too! My mom drank a lot of it and her first seven children had penises so small they were clits!!! haha! If it were that easy the gender reassignment people would be out of business!

If you want to get into the biological aspects of it, Mountain Dew does have a higher amount of caffeine than other soft drinks. And while caffeine is said to be a stimulant, it is also a diuretic that forces water out of the body. And with the blood being over 90% water, the increased caffeine reduces the viscosity of the blood, which could inhibit a healthy erection.

So that's what happened!?

ridiculous theory
