Let’s get one thing out of
the way right now: Despite what your awful ex or the latest douching ads say,
your vagina is supposed to have a bit of an odour.
Sometimes a little musty
“Just like with the gut, the vagina has its own microbiome filled
with different bacteria and yeast, many of which are incredibly helpful,” says
Dr Mary Jane Minkin, a clinical professor of obstetrics and gynaecology at the
Yale University School of Medicine in New Haven, Connecticut. And, yep, those
bacteria give your vag its signature scent.
But uh, what does that typically smell like? “The acidic pH naturally
found in the vagina might make it a little sour smelling, sometimes a little
musty,” says Dr Christine Masterson, obstetric-gynaecologist and chief of the
women and children’s service line at Summit Medical Group. “But it shouldn’t be
an overwhelming odour.”
Still, there are times when you catch a waft that smells a
bit… off. The cause can be as innocuous as sweat or as troubling as an
infection, says Dr Minkin, so it’s worth taking a deeper whiff (yes, really),
especially if the unusual aroma is accompanied by symptoms like itching or
Scan through the scents below to see if your smell is on our list,
but don’t hesitate to get yourself checked out by a professional either way.
The most likely culprit behind this scent is bacterial vaginosis
(BV), the most common vaginal infection in women ages 15 to 44, according to
the Centers for
Disease Control and Prevention (CDC). The infection can creep
in when the vagina’s pH gets thrown out of whack by an overgrowth of “bad”
bacteria, says Dr Minkin.
Docs aren’t sure why this happens, but BV isn’t an STI, stresses
Dr Minkin, so BV on its own is pretty harmless. Still, you may be able to
re-balance your vaginal acidity with some over-the-counter “pH warfare”, says
Dr Minkin. Check your local drugstore for a pH gel, which is designed to
balance out your vagina’s pH and nix odours.
If this doesn’t take away the smell within a week or so, see your
ob-gyn. You might need an antibiotic to clear up the infection, or you might
actually have trichomoniasis, a common and easily treatable (via antibiotics)

Most yeast infections aren’t terribly smelly, but occasionally the
thick, cottage cheese-like discharge that’s a hallmark of the itchy nuisance
has a faint scent of beer or yeast. If you notice redness or burning around
your vagina, or have pain after you pee, this is the likely cause, says Dr
Diabetic women may especially notice this since yeast feed on
sugar, and diabetic women tend to have more glucose (a.k.a. sugar) in their
vaginal secretions, says Dr. Minkin. See your doc about what’s going on down
there, and she might prescribe something or recommend something you can buy
Two questions: Did you just pound out a major sweat session at the
gym and are you wearing synthetic underwear (think: nylon or polyester)?
Exercise and non-breathable knickers can cause a musky smell from
trapped sweat, says Dr Minkin. It should go away as soon as you shower (use
just water or a mild soap). To minimise the scent in the future, switch to
cotton undies (or at least ones that have a cotton lining) and don’t sit around
with sweaty clothes.
Of all the scents your vagina can have, this is definitely the
most concerning one. A tampon that’s been left in your vagina for days or
longer can smell rancid or foul. “The scent is brought on by an overgrowth of
bacteria in a confined space,” she says.
To dislodge it yourself, lie on your back or squat with one foot
propped on the toilet, then reach into your vagina with clean fingers to search
for the string. No luck? See your ob-gyn who can use a speculum to get the job
One thing to note, though: If left behind too long the bacteria
can sometimes (but rarely) trigger toxic shock
syndrome, a deadly condition linked to tampon use. If you know your
tampon’s been in for more than eight hours (or, tbh, you can’t remember the
last time you changed it), and you’ve got flu-like symptoms (fever, nausea,
achiness), it’s time to see a doc, asap.

Blood (you know, from your period) can change the pH of your
vagina, making it smell coppery or tinny, says Dr Minkin. You can wash
your vulva with soap – just avoid going crazy with strong scented soaps because
they can throw the pH even further out of whack, says Dr Minkin. But other
than that, you’ve just gotta ride this one out.
There’s a couple different reasons why your vagina might take on a
chemical smell of bleach or ammonia: Dr Masterson says that BV – which,
again, usually smells fishy – can sometimes smell like ammonia instead.
There’s also a chance that the smell is actually coming from your
urine, especially if you’re dehydrated. Lastly, Dr Masterson says that
intercourse (specifically the low-acid pH level of sperm) can trigger an
ammonia smell, and so can any lubricants and spermicides you might have used.
Basically, you can wait this smell out a little bit to see if it fades on its
own. If it doesn’t in a few days, check in with your obstetric-gynaecologist.

If you notice a sweet smell down there, you might not be super
inclined to think anything is wrong (it’s better than a rotten smell, right?!).
And you’re pretty much right: Dr Masterson says this is usually diet-related.
“Sometimes citrus fruit can cause a sweet odour,” she says.
“Asparagus and garlic are known to change the way urine and discharge smell,
That said, she adds that yeast can sometimes cause a sweet odour,
so if you’re also having symptoms of a yeast infection,
grab an OTC treatment or check in with your doc.
