Have you noticed your vaginal odor has changed in perimenopause or menopause? That things just smell different or stronger than they did before? If so, you can relax, because this is a normal phenomenon. And most of the time, it’s pretty simple to address vaginal odor during menopause.
Vaginal odor in menopause is common, caused by declining estrogen, an imbalanced microbiome, and pH that’s suddenly off down there.
First, you’ve got to make sure you don’t have an infection going on, which is possible because, as estrogen levels change, your microbiome shifts, and it becomes easier for pathogens to thrive.
Then, supporting your vaginal microbiome and pH with diet, probiotics, and vulvar moisturizer goes a long way. Here’s how to tackle the problem holistically.
Healthy Vaginas Smell…Like Vaginas
First of all, let’s get a huge misconception out of the way. Your vagina is not meant to smell like roses, a fresh ocean breeze, or strawberries and champagne.
Vaginas have a scent. Yours is unique to you. But generally, it’s a softer, inoffensive smell that may be a little on the tangy, musky side. Maybe a bit like sourdough bread starter, if you’ve ever smelled that. Or molasses.
Having a little bit of a smell down there doesn’t mean you are dirty or have poor vaginal hygiene. It just means you have a functioning colony of microbes that reside in the neighborhood. When they are doing their job, they release gases that have a slight smell to them.

Does Menopause Cause Vaginal Odor?
During perimenopause and menopause, you may notice significant changes to the light smell you’ve been accustomed to smelling for most of your life.
You may notice:
Changes in odor
The most frequently reported complaint. Menopause vaginal odor can range from a mild, unfamiliar scent to something more pronounced and fishy. It may be constant, or it may come and go. Many women notice it's worse after sex, after exercise, or at certain points in the month.
Changes in discharge
Vaginal discharge after menopause often becomes thinner, more watery, or less frequent than before. Some women, particularly in perimenopause when hormones are still fluctuating, experience more discharge than usual. Color can shift to yellow or grayish, which often accompanies changes in smell. Discharge may become thicker or resemble cottage cheese.
Dryness paired with odor
It might seem contradictory, but vaginal dryness and odor often go hand in hand. As tissue thins and natural lubrication decreases, the entire vaginal environment shifts — including its scent.
Itching, irritation, or a burning sensation
These can accompany odor changes and may signal a secondary issue like bacterial vaginosis or a yeast infection layered on top of the hormonal changes already underway.
Perimenopause vaginal odor that comes and goes
If you're still cycling but noticing new smells that seem random or cyclical, this is classic perimenopause territory. Hormones fluctuating unpredictably create an equally unpredictable vaginal environment.
These are all clues to what’s going on in your body right now. Your vaginal odors and discharge are sending signals. Let’s talk further about how to decode them.
What Causes Menopause Feminine Odor?
Menopause creates a confluence of factors that can trigger odors down below, including the following.
Estrogen Decline and Vaginal Atrophy (GSM)
Estrogen is one of the foundations of vaginal health. It keeps tissues thick, elastic, and well-lubricated. It maintains the glycogen content of vaginal cells. And critically, it supports the beneficial bacteria that keep your vaginal environment in balance.
When estrogen drops, whether you're in the hormone rollercoaster of perimenopause or the lower, more stable levels of postmenopause, vaginal tissues thin and dry out.
This is known as Genitourinary Syndrome of Menopause (GSM). GSM fundamentally alters the biochemical environment in ways that directly affect odor and discharge, and affects 27-84% of women. (1,2)
Urinary Leakage
One of the big symptoms of GSM? Urinary leakage. That’s because when your estrogen drops, it affects all of your tissues down there, including your urethra and pelvic floor.
This often leads to incontinence, which may be subtle at first.
Tiny drops of urine can leak out, then dry on your underwear. This can be a huge source of odors during menopause. And it can lead to further microbial imbalances, which cause odors.
Rising Vaginal pH
Healthy vaginal pH in a premenopausal woman sits between 3.8 and 4.5, moderately acidic. (3) This creates an environment that suppresses harmful bacteria while supporting protective ones. Estrogen is what maintains this acidity.
So when estrogen declines, pH rises — often to between 5 and 7. (4)
That shift toward alkalinity matters enormously. Harmful bacteria thrive in a higher-pH environment, multiplying and producing chemical byproducts called amines. And amines are what create that distinct fishy odor. This is why vaginal odor after menopause is often worse after sex: semen is alkaline and temporarily raises vaginal pH, triggering the odor-producing bacterial response.
Disruption of the Vaginal Microbiome
Your vagina is home to an entire ecosystem of bacteria, and in a healthy, premenopausal environment, it's dominated by one genus: Lactobacillus. Lactobacillus produces lactic acid (which keeps pH low), hydrogen peroxide (which suppresses harmful bacteria), and other protective compounds. A Lactobacillus-dominant microbiome means low odor, low infection risk, and high comfort.
Estrogen feeds Lactobacillus. So when estrogen declines, Lactobacillus populations drop. (5,6) And the space they used to occupy doesn't stay empty…other bacterial species move into the neighborhood. These newcomers produce the amines and compounds responsible for the odors you notice in menopause.
This is one of the core biological mechanisms behind the pressing question "why do I smell during menopause?" and it's also why the problem tends to recur without addressing the underlying biology.
The pH-microbiome relationship is a self-reinforcing cycle: fewer Lactobacillus → less lactic acid → rising pH → better conditions for harmful bacteria → further Lactobacillus displacement.
Once the cycle begins, it tends to perpetuate itself.
These changes to the vaginal microbiome can also allow yeast to thrive. While yeast infections may not produce a strong odor in the same way bacterial vaginosis does, they certainly can change the way your vagina smells.
Bacterial Vaginosis (BV)
Can menopause cause a fishy odor?
Yes, menopause can cause a fishy odor, and BV is the most common reason why. BV isn't an infection in the traditional sense; it's an overgrowth of bacteria that naturally live in the vagina when the environment tips out of balance.
In menopause, that tipping is almost inevitable without support: estrogen decline, rising pH, and depleted Lactobacillus all create prime conditions for BV. This is why women in perimenopause and menopause are more prone to recurrent BV. (7,8)
Can menopause cause a fishy smell even without BV? Sometimes. But if the odor is distinctly fishy and accompanied by thin grayish discharge, BV is the most likely explanation. The good news is that it's one of the most treatable aspects of menopause vaginal odor.
Changes to Vulvar Skin and Sweat Glands
The external vulvar tissue changes with age and declining estrogen as well.
Skin thins, sebaceous glands shift, and the moisture balance of the area changes. This can contribute to menopause feminine odor even when the internal vaginal environment is relatively stable.
And it's often exacerbated by synthetic underwear, tight clothing, or artificially fragranced products applied to sensitive skin.

Lifestyle Factors
Diet, stress, sleep, and hygiene habits all influence the vaginal ecosystem in ways that become more pronounced in menopause.
High sugar intake can feed bacterial and yeast overgrowth. Chronic stress affects immune regulation. And the products most heavily marketed to address feminine odor, like douches, scented sprays, fragranced washes…all actually make things worse by further disrupting pH and wiping out beneficial bacteria. The vagina is self-cleaning; it doesn't need artificial fragrance to mask smells. It needs its natural ecosystem intact.
6 Steps To Fix Vaginal Odor
Supporting your body so it can get back to smelling like its normal self involves rebuilding the foundation of your vaginal health. Here’s how.
1. Support The Vaginal Microbiome
Supporting your microbiome with vaginal probiotics containing Lactobacillus strains may help to strengthen the “good guys” in your microbiome so they edge out the ones causing the odors.
Some of the more well-researched strains include (9):
Lactobacillus crispatus (LBV 88)
Lactobacillus gasseri (LBV 150N)
Lactobacillus jensenii (LBV 116)
Lactobacillus rhamnosus (LBV 96)
Lactobacillus acidophilus (LA-5)

Fermented foods like yogurt, kefir, kimchi, and sauerkraut also support broader microbiome health.
And if you need to take antibiotics for any reason, always follow up with probiotics. Broad-spectrum antibiotics wipe out Lactobacillus along with harmful bacteria. Restoring the microbiome afterward matters.
2. Restore And Maintain Healthy pH
Avoid alkaline disruptors: no douching, no scented soaps or sprays near the vaginal opening, no artificially fragranced products.
Plain warm water for external cleansing is sufficient.
Boric acid vaginal suppositories are available over the counter and could help restore acidic pH, which antecdotally may be particularly supportive for BV. Discuss them with your provider, and see if they are right for you.
3. Rethink Your Daily Habits
You may not love this suggestion, but try switching to plain, cotton underwear. Cotton breathes; those sexy, lacy synthetics trap warmth and moisture, creating conditions where bacteria thrive.
Change out of sweaty workout clothes promptly rather than wearing them for hours after exercise.
Simplify your hygiene routine. Less really is more. Gentle, unfragranced cleansing of the external vulva is all that’s necessary. Never clean inside the vaginal canal with soap.
Look at your diet. Reducing refined sugar and alcohol, increasing hydration, and eating more fiber and fermented foods can all support a healthier vaginal environment.
One of the best things you can do for your vaginal microbiome, pH, and menopausal vaginal odors is to quit sugar. Here’s a sustainable way to start the journey.
4. Moisturize Your Vulva
When things smell off down there, and you’re feeling dry, itchy, or irritated, I always recommend moisturizing the skin directly with something emollient that won’t further disrupt the vaginal flora.
5. Talk To Your Doctor
If you're experiencing persistent or strong vaginal odor after menopause, or recurrent discharge changes, a conversation with your healthcare provider is a critical step. BV, yeast infections, and other imbalances are easily diagnosed with a simple swab. You may have an infection going on. Knowing exactly what you're dealing with means you can treat it correctly rather than guessing.
Remember, if you are prescribed antibiotics for BV or an infection, be sure to follow them up with a high-quality probiotic. Many times, BV becomes recurrent without the right support for your wider microbiome.
Also, be sure to ask about local (vaginal) estrogen therapy. This may be one of the most effective interventions available for GSM and all its downstream effects. We don’t have a ton of research tying it to odor relief directly, though. Because it's applied directly to the vaginal tissue rather than taken systemically, very little enters the bloodstream, making it appropriate for many women who aren't candidates for systemic hormone therapy.
I hear a lot of women who are worried about the potential side effects of estrogen therapy and cancer risks. Even though they’ve removed the FDA black box warning, it still gives a lot of women pause, which is understandable after years of being told it isn’t safe. Have an honest discussion with your doctor about it and see if it’s appropriate for you.
Most menopause vaginal odor is manageable and not a sign of anything serious. But see your provider promptly if you notice:
A strong fishy or foul odor paired with gray, green, or frothy discharge
Itching, burning, or significant discomfort alongside odor
Any blood-tinged discharge after menopause — this always warrants evaluation
Symptoms that recur frequently despite treatment
Anything that feels new, concerning, or is affecting your quality of life
6. Pelvic floor therapy
Pelvic floor physical therapy (PFPT) is one of the most underutilized and genuinely transformative tools available for menopausal vaginal health, and it may directly impact the conditions that contribute to odor and discharge changes.
That’s because PFPT addresses many of the broader GSM symptoms that cluster together in menopause: painful sex, urinary leakage, pelvic pressure, and vaginal dryness. Treating these as a connected system, rather than isolated complaints, tends to produce far better outcomes. (10)
I’ve seen women use Julva in conjunction with PFPT for wonderful results.
Vaginal Odor In Menopause
Vaginal odor in menopause is not a hygiene problem or a personal failing. It's a biological signal. Your body is telling you that estrogen has declined, pH has shifted, and the vaginal microbiome needs support.
I know it’s frustrating. Trust me. But don’t feel ashamed, and don’t worry. Just stick to the basics, and you’ll be feeling fresher in no time.
FAQ
How to get rid of menopause smell down there?
The most effective approach to get rid of vaginal odors in menopause targets the root cause rather than masking the odor.
Start by seeing your provider to rule out bacterial vaginosis, which is easily treated. From there, local vaginal estrogen therapy, vaginal probiotics containing Lactobacillus strains, and boric acid suppositories could all help restore the pH and microbiome balance that menopause disrupts.
Avoid artificially scented products, douches, and synthetic underwear. These strategies can remove common irritants that make things worse. For many women, a combination of two or three of these approaches produces the most lasting results.
Can menopause cause a fishy odor?
Yes, menopause can cause a fishy odor. And it's more common than most women realize. The fishy smell associated with menopause is typically caused by bacterial vaginosis (BV), which becomes significantly more prevalent after estrogen begins to decline.
Lower estrogen raises vaginal pH and depletes Lactobacillus, the protective bacteria that normally keep odor-causing bacteria in check. When those bacteria overgrow, they produce compounds called amines, and amines smell distinctly fishy. The good news is BV is treatable, and addressing the underlying hormonal and microbiome shifts can reduce how often it recurs.
Will hormone therapy help with vaginal odor?
Hormone therapy may not help with vaginal odor directly, but local (vaginal) estrogen therapy may help some of the underlying issues that cause vaginal odor.
Because estrogen decline is the root cause of most menopausal vaginal odor — triggering pH changes, tissue thinning, and microbiome disruption…restoring estrogen to the vaginal tissue can reverse much of that cascade. Local estrogen comes in the form of creams, suppositories, or a vaginal ring, and because it works directly on the tissue with minimal systemic absorption, it's appropriate for many women. Systemic hormone therapy (pills or patches) can also help, but for vaginal symptoms specifically, local delivery tends to be more targeted and effective. Talk to your provider about which option makes sense for your overall health picture.
Are vaginal dryness and odor linked?
Yes, vaginal dryness and odor are linked. Both are symptoms of the same underlying shift: declining estrogen leading to thinner vaginal tissue, reduced lubrication, and rising pH.
When the vaginal environment dries out, the ecosystem that controls odor, particularly the Lactobacillus-dominant microbiome, loses the conditions it needs to thrive. Harmful bacteria move in, pH climbs, and odor follows. Treating dryness (through local estrogen, vulvar moisturizers, or both) very often improves odor as well, because you're restoring the broader vaginal environment rather than chasing individual symptoms.
