If urine is "so sterile", why does it smell bad?
maybe it doesn't smell bad coming out, but when someone pisses in an alley it always stinks! and if someone pees in a public toilet and leave it, that stinks too! so how does it go from being sterile to being so nasty?
Asked by Norman Fentress 2 years ago.
Sterile doesn't mean without smell, it means without bacteria/infectious disease. Animals excrete uric acid and urea, which breakdown upon excretion to ammonia, which stinks. Animals also excrete MHC compounds (major histocompatibility complex) which is a way of of using our sense of smell to identify kin and non-kin. Rats and mice use it quite a lot for assortative mating, as do humans. ANYWAY, other people stink to us and some of the odor is that its someone else's urine. And, in my opinion, male urine reeks the most. Did you know that pregnant women's urine was the only urine used to treat and tan walrus hides for umiaks and in general to treat hides for tanning by the Yupik peoples? Presumably because gals pee doesn't stink as badly. Male urine would work, but the smell is up there - I assume from the pheromones. Answered by Lanita Waston 2 years ago.

Why Does Urine Smell Bad Answered by Jerome Sloman 2 years ago.
Urine is sterile as it leaves the body as long as a person is healthy, but it picks up bacteria from skin upon exiting. As it sits there, especially in a warm, moist environment, that bacteria will grow exponentially, many times causing a bad smell. There are many things that can make urine smell. Being dehydrated causes one's urine to have a strong ammonia smell. Someone with diabetes often has sweet smelling urine, and a foul smell indicates a bacterial infection of the kidneys or bladder. I work in a microbiology lab, where we do hundreds of urine cultures each day. I've seen plenty of non-sterile urine cultures. Answered by Delana Cordel 2 years ago.
Here is an experiment for you. Eat a nice big plate of asparagus. Go ahead, it tastes great and it is good for you. The next batch of urine will smell awful. You do not have bacteria, you are simply passing the smelly breakdown products of the compound asparagine. Many other chemicals that have odor find their way into urine because the body is getting rid of waste, or surpluses of those compounds. You are right that urine goes bad fast and smells strong, but that is mostly due to bacteria that grow in the urine after it is out of the body. Answered by Owen Baurer 2 years ago.
urine is generally sterile when it comes out, but it doesn't stay that way one it hits the ground. All sorts of bacterial processes and chemical reactions occur that convert urine into smelly chemicals. One of the first reactions is the conversion of uric acid to urea and ammonia. Both of these chemicals have a strong odor and they also irritate the mucosal linings of the nasal passages and lungs. Answered by Asley Rissler 2 years ago.
um.... this is a weird question but i know the answer. urine is 95% water and 5% waste that is why it smells bad. i think the reason it doesnt smell coming out is because when it touches oxygen the waste part multiplies.... Answered by Deloise Hinaman 2 years ago.
Do you know if urine is sterile?
i have found out that human urine is sterile or atleast mostly if it doesnt pick up bacteriea on the way out of te body but is all urine sterile or are different animals' urine different i know this is a wierd question but i want to know lol
Asked by Sara Flowe 2 years ago.
Whether it's sterile or not would depend on the person. If it's a normal person, yes...it is sterile. It has no bacteria or whatever. It was filtered to contain only those simplest smallest molecules such as water and urea. Even blood proteins aren't included. They even clean snake bites with urine when you can't find water(in the forest). However, there are some conditions where your kidneys might not be working properly and blood might be excreted along with your urine. In cases like these, it is no longer sterile. Just stick to your anti-septic, I'm sure it's available in pharmacies. :D Answered by Tyrell Scammon 2 years ago.
I wouldn't call it sterile necessarily, but it is definitely the cleanest bodily fluid there is, as urine goes through a filtering process before being eliminated from the body. I would NEVER do it, but I actually saw a special on TV that said people can drink their own urine. Nasty! Answered by Delphia Rosendahl 2 years ago.
Which is the most and least sterile fluid that the body secretes?
by sterile i hope to mean containing the least amount of bacteria; taking into account sweat, urine, vaginal secretions, tears, saliva, mucus, and any more that i cant think of...
Asked by Fredericka Fire 2 years ago.
urine is the most sterile bodily fluid because it has a high concentration of urea. the reason it can kill you after passing it through twice is not because it is sterile, but because you are re absorbing the waste that your body was trying to get rid of the least sterile would probably be feces. Answered by Signe Shellman 2 years ago.
Aside from poop, probably saliva is the least sterile. Urine, CSF, and blood are considered sterile, but any bodily fluid can have some microorganisms in it. The GI tract just happens to be so non sterile you don't need to observe sterile fields during a GI exam. Answered by Lillia Edwin 2 years ago.
Unless there is a urinary tract infection, urine is the most sterile fluid produced (until it hits the air). Answered by Nora Krajcer 2 years ago.
Pee, the first time through(ie. water, soda, milk) is the most sterile. Pee is also the least sterile. After it has been drunk and has gone through once, it can kill you. If you are ever in a situation where you must drink your pee to live, DO NOT DRINK YOUR PEE MORE THAN 1 TIME! Answered by Malia Deshayes 2 years ago.
If urine is sterile, why do we have to wash our hands after we use the bathroom?
Asked by Libby Pestana 2 years ago.
Urine is mostly sterile, and definitely safe to drink. Most people forget that urine is mostly water. Water is the filter of the human body. Waste that our cells produce, collectively known as urea, ends up in our bloodstream. Our kidneys remove the urea, along with excess water, and the result is urine. Now, you ask if it's sterile - and yes, for the most part it is - but as urine leaves the body - that's where it picks up the other bacteria that exists outside the body, on the toilet stool, etc. It is necessary to wash our hands often - just to remove the bacteria from it. The hands often pick up much of the bacteria that we attribute to colds, flu, and other things. To be honest - we don't wash our hands nearly enough. Answered by Fonda Leonaggeo 2 years ago.
Urine is generally considered to be sterile. When it leaves the body, however, the urine can pick up bacteria from the surrounding skin, which would contaminate it. Therefore we wash our hands to prevent that bacteria from entering other parts of our body. Answered by Georgeann Dubrow 2 years ago.

Well, I assume you are not peeing on your hands but you are touching your genitals when you wipe and they can be full of bacteria.

Is it true that human urine is sterile?
Asked by Lu Minaai 2 years ago.
yes. urine is virtually sterile and nearly odorless. Subsequent to elimination from the body, urine can acquire strong odors due to bacterial action. Most noticeably, the asphyxiating ammonia is produced by breakdown of urea. Some diseases alter the quantity and consistency of the urine, such as sugar as a consequence of diabetes.

Urine is sterile while it is in the bladder (unless one has a bladder infection). However, the ureter is open to the outside world and is not sterile, so once urine leaves the bladder it is no longer sterile. Answered by Paul Sautner 2 years ago.

Asked by Gidget Riveron 2 years ago.
The urine goes through the kidneys where it is filtered. Any waste products from the filtering goes into your ****, leaving your urine relatively clean and sterile. Urine is sterile until it reaches the urethra where the epithelial cells lining the urethra are colonized by facultatively aerobic Gram negative rods and cocci. Urine is a transparent solution that can range from colorless to amber but is usually a pale yellow. Urine is an aqueous solution of approximately 95% water, with the remaining percentages being metabolic wastes such as urea, dissolved salts, and organic compounds. Fluid and materials being filtered by the kidneys, destined to become urine, come from the blood or interstitial fluid. Answered by Deloris Cord 2 years ago.
Urine is absolutely sterile unless you have an infection. Don't mean to be a jerk but can't understand why people post answers when they really don't know the answer? This is easily verified on almost every reputable medical website such as the nih.gov website. Normally, urine is sterile. It is usually free of bacteria, viruses, and fungi but does contain fluids, salts, and waste products. An infection occurs when tiny organisms, usually bacteria from the digestive tract, cling to the opening of the urethra and begin to multiply. The urethra is the tube that carries urine from the bladder to outside the body. Most infections arise from one type of bacteria, Escherichia coli (E. coli), which normally lives in the colon. In many cases, bacteria first travel to the urethra. When bacteria multiply, an infection can occur. An infection limited to the urethra is called urethritis. If bacteria move to the bladder and multiply, a bladder infection, called cystitis, results. If the infection is not treated promptly, bacteria may then travel further up the ureters to multiply and infect the kidneys. A kidney infection is called pyelonephritis.

Is urea a component of DMSO?
Asked by Kattie Hurry 2 years ago.
Dimethyl sulfoxide (DMSO, RIMSO-50) was the first of two therapies approved by the US FDA for the treatment for IC in the early 1970's. Its use has quickly diminished due to the growing popularity of rescue Instillation's and research that suggests that DMSO can be damaging to the bladder muscle. Many clinics no longer use DMSO treatments. IT ISN"T A GOOD IDEA to have DMSO Tx in my opinion, I had them, made it worse then before! It burns the bladder, and originally was used on animals! If your question relates to having treatments, I strongly suggest to get a second opinion, but if it is for lab testing/experiments, I doubt it very seriously, a waste product of urine would be part of a compound placed into the bladder. I'm saying "no" from what I know. :o) DMSO is a dilute, sterile, and purified version of a chemical that was used for many years as an industrial solvent before being found to have anti-inflammatory, analgesic, muscle relaxant, mast cell stimulation and collagen dissolution properties. Urological Association suggests that DMSO may cause damage to the muscle of the bladder when used at the 50% dosage. In "DMSO - Does it change functional properties in the bladder wall" researchers tested various concentrations of DMSO on strips of bladder muscle to try to determine what, if anything, the DMSO did to muscle. They found that DMSO triggered intense muscle contractions and, at doses higher than a 30% solution, caused what appeared to be long-lasting contractions that could be irreversible. Since the normal FDA approved dosage used for humans is 50%, researchers suggested that the dosage be reduced to, at most, 25% to avoid any possibility of muscle damage. It is dissolved in blood and excreted by the kidney as a component of urine. In addition, a small amount of urea is excreted (along with sodium chloride and water) in sweat. UREA is a waste product, I doubt it would be part of a DMSO cocktail for humans, but maybe in animals it may have some purpose? Answered by Forest Vonstein 2 years ago.
No. And FWIW, DMSO has a big hazard warning on it that says: "MSDS recommends wearing safety glasses because DMSO can cause chronic damage to the eyes. Glove selection is important when working with DMSO. Thick rubber gloves are recommended." Answered by Tana Pronto 2 years ago.
No, but the compounds are similar. Urea is a s double bonded to an O, and flanked by two nh2 (amine) groups. DMSO is flanked by two methyl groups instead. Answered by Douglas Berends 2 years ago.

Urine is sterile (good for washing wounds in an emergency) The concentration of urea is not sufficient to have much effect and it is soon washed off Birds (like bald eagles) use urea to keep their legs free of parasites and infection but its very concentrated - bird cr.p might help with athletes foot but thats considerably less convenient and would probably burn Answered by Kris Gorney 2 years ago.
