What does a vagina smell like?https://www.healthline.com/health/womens-health/vagina-smells#1Normal smells for a healthy vaginaTangy or fermentedIt’s very common for vaginas to produce a tangy or sour aroma. Some compare it to the smell of fermented foods. In fact, yogurt, sourdough bread, and even some sour beer contain the same type of good bacteria that dominate most healthy vaginas: Lactobacilli.If it smells curiously similar to that sour IPA you had last weekend, don’t freak out.Reasons for a tangy odorAcidity. The pH of a healthy vagina is slightly acidic, between 3.8 and 4.5. “The Lactobacilli bacteria keep the vagina acidic,” says Minkin. “This protects against an overgrowth of the bad kinds of bacteria.”Coppery like a pennyMany people report smelling a coppery, metallic vaginal odor. This is usually nothing to worry about. Rarely, it signifies a more serious problem.Reasons for a coppery odorBlood. Blood contains iron, which has a metallic smell. The most common reason for blood is menstruation. During your period, blood and tissue shed from your uterine lining and travel through your vaginal canal.Sex. Light bleeding after sex can be common. This is usually due to vaginal dryness or vigorous sex that can cause small cuts or scrapes. To prevent this, try using lube.A coppery smell can also be due to less common, but serious, causes of vaginal bleeding. The metallic scent shouldn’t linger too long after your period is over. If your vagina has had contact with semen, this may change the pH level and cause a metallic smell.Sweet like molassesWhen we say sweet we don’t mean freshly baked cookies sweet. We mean robust and earthy. But don’t fret, a sweetish tinge is no cause for concern.Reasons for a sweet odorBacteria. Yep, bacteria again. Your vaginal pH is an ever-changing bacterial ecosystem. And sometimes this means you might smell a little sweet.Chemical like a newly cleaned bathroomAn odor similar to bleach or ammonia could be a couple of different things. Sometimes, this odor is a reason to see a doctor.Reasons for a chemical odorUrine. Urine contains a byproduct of ammonia called urea. A buildup of urine in your underwear or around your vulva could put off a chemical smell. Keep in mind, urine smelling strongly of ammonia is a sign of dehydration.Bacterial vaginosis. It’s also possible a chemical-like smell is a sign of bacterial vaginosis. “A chemical smell often falls under the category of fishy,” says Minkin.Bacterial vaginosis is a very common infection. Symptoms include:a foul or fishy odorthin gray, white, or green dischargevaginal itchingburning during urinationSkunky like BO or a smoked herbal, earthy scentNo, it’s not just you. Many people find a similarity between body odor and marijuana. Sadly, there isn’t a good scientific answer for this, although Vice did take a stab at it. But thanks to the sweat glands down there, at least we do know why vaginas and body odor can smell so similar.Reasons for a skunky odorEmotional stress. Your body contains two types of sweat glands, apocrine and eccrine. The eccrine glands produce sweat to cool your body down and the apocrine glands respond to your emotions. These apocrine glands populate your armpits and, you guessed it, your groin.When you are stressed or anxious, the apocrine glands produce a milky fluid. On its own this fluid is odorless. But when this fluid contacts the abundance of vaginal bacteria on your vulva, it can produce a pungent aroma.Fishy or that fillet you forgot aboutYou’ve probably heard an abnormal vaginal odor described as fishy. In fact, fresh fish shouldn’t smell like much at all. Decomposing fish is the more apt comparison. Why? Trimethylamine, which is the chemical compound responsible for both the distinct aroma of rotting fish and some abnormal vaginal odors.Reasons for a dead fish odorBacterial vaginosis. “You get bacterial vaginosis when there’s an overgrowth of anaerobic bacteria in the vagina,” says Minkin. “And these anaerobic organisms are odorous.”Trichomoniasis. Trichomoniasis is the most common curable sexually transmitted infection and easily treatable with a course of antibiotics. It’s known for its pungent fishy odor. “The trichomoniasis infection can be quite smelly,” says Minkin. “It’s a more pronounced fishy odor than bacterial vaginosis.”Rotten like a decaying organismA rotten odor that makes your nose wince and your face contort is definitely not the norm. If the smell is putrid, like a dead organism, it may not be your vagina but something in your vagina.Reasons for a rotten odorA forgotten tampon. Inadvertently letting a tampon go days, even weeks, inside a vagina is much more common than you’d think. “I can’t tell you how many tampons I’ve taken out of patients,” says Minkin. “This happens to lots and lots of people. It isn’t something you need to be embarrassed about.”See your doctor if an odor is accompanied by:itching or burningpainpain during sexthick, cottage cheese dischargevaginal bleeding unrelated to your periodMenopause changes the pH level with the change estrogen levels. Pregnancy changes the pH level tooPlus your smell of smell can be enhanced while pregnant and you might smell your vagina more, but don’t worry no one else can.
